RESUMO

Hypertrophic cardiomyopathy (HCM) with left ventricular outflow tract obstruction that doesn't improve with pharmacological management often requires septal myectomy. However, there are few centers with experience in the practice of this procedure in our country. We describe the clinical and echocardiographic characteristics and postoperative outcomes of patients with HCM indicated for septal myectomy at a reference center in Colombia. MATERIALS AND METHODS: Retrospective cohort study. Patients undergoing septal myectomy between 2010 and 2023 were included. Data were collected before and two years after surgery. RESULTS: 18 patients were included. The mean age was 50 years. The predominant functional class was NYHA II/III (94 %). Asymmetric septal variant (83.3 %) was the most frequent as well as obstructive phenotype (88.8 %). After myectomy, 70.5 % improved to NYHA I and 62.4 % had no significant gradient (<30 mmHg), and the most of patient improved SAM. One patient died post-procedure, anymore complications were presented. DISCUSSION/CONCLUSIONS: Septal myectomy is a safe procedure, with clinical and echocardiographic improvement, with low complication rates.

RESUMO

BACKGROUND: To evaluate the feasibility of an abbreviated focus-assessed transthoracic echocardiography protocol in morbidly obese patients. The purpose of this study was to evaluate whether good images could be obtained from this particularly difficult group of patients for whom acoustic imaging is often poor. Heart imaging could be helpful for cardiopulmonary screening and real-time monitoring. METHODS: The study included 186 morbidly obese patients, who underwent laparoscopic bariatric surgery. The mean patient age was 32 years (range 21-52), and there were 95 males. The parasternal long and short axes and apical 4 and 5 chambers were evaluated. RESULTS: In 95% of the patients, at least one view was obtained. In 78%, two views were obtained, and in 31% of the patients, all views and measurements could be performed. CONCLUSION: In obese patients, a modified focused echocardiography examination performed by anesthesiologists in the intraoperative period of morbid obese patients is feasible. The image quality was sufficient to undergo interpretation.

RESUMO

Resumen Introducción: El origen aórtico anómalo de las arterias coronarias tiene una prevalencia estimada del 0.02-5.7% y están potencialmente involucradas con complicaciones en su evolución natural o aquellos que requieran procedimientos intervencionistas hemodinámico y/o quirúrgicos. Puede asociarse a muerte súbita o dañarse durante intervenciones sobre el anillo mitral, aórtico, pulmonar o el cierre percutáneo de un defecto septal interauricular. Objetivo: identificar estos pacientes por diferentes técnicas de imágenes como el ecocardiograma Doppler color transtorácico (ETT), angiotomografía o angiografía coronaria. Métodos: Las técnicas de imágenes utilizadas para la detección de anomalías coronarias fueron el ETT, angiotomografía coronaria multicorte o angiografía coronaria convencional de acuerdo con lo universalmente aceptado. Resultados: Estudio prospectivo realizado desde enero del 2020 a junio del 2021. Se identificaron 15 pacientes y en 12/15 la sospecha fue por ETT y en los tres restantes por angiotomografía coronaria. La arteria circunfleja fue la más involucrada en forma aislada o asociada a otra anomalía coronaria (12/15 pacientes) y en los tres casos restantes la coronaria anómala tuvo un trayecto interarterial, siendo las arterias coronarias derecha y la descendente anterior las afectadas. Conclusiones: El subdiagnóstico por ETT de las anomalías de las arterias coronarias puede deberse a la dificultad para su visualización, sobre todo en la población adulta. Su detección es crucial, ya que puede generar muerte súbita asociada a isquemia miocárdica y arritmias graves o complicar procedimientos intervencionistas sobre el septum interauricular o sobre los anillos mitral, pulmonar y/o aórtico.

Abstract Introduction: The anomalous aortic origin of the coronary arteries has an estimated prevalence of 0.02-5.7%. It can be associated with sudden death when it has an interarterial or intramural pathway or be damaged during interventions on the mitral, pulmonary and/or aortic annulus or percutaneous closure of an interatrial septal defect. Objective: To identify these patients by imaging techniques such as transthoracic color Doppler echocardiography (TTE), computed tomography (CT) multislice angiography or coronary angiography. Methods: The imaging techniques used for the detection of coronary anomalies were TTE, multislice coronary angiography or coronary angiography according to what is generally accepted. Results: Fifteen patients were identified; in 12 of them the suspicion was due to TTE and in the remaining 3, CT multislice angiography was diagnostic. The circumflex artery was the coronary artery most involved, associated or not with another coronary anomaly (12/15 patients) and in the other three cases, the anomalous coronary artery had an interarterial course, with the right coronary arteries and the anterior descending coronary arteries being involved. Conclusions: The under diagnosis by TTE of coronary artery abnormalities may be due to the difficulty of visualization that is accentuated with age. Their detection is crucial because they can both, lead to sudden death associated with an intramural and/or interarterial pathway and complicate an interventional procedure on the interatrial septum or within the mitral, pulmonary and/or aortic rings.

RESUMO

Intramyocardial dissecting hematoma is a form of cardiac rupture caused by myocardial infarction, percutaneous coronary intervention, or trauma. It is a cavity between myocardial fibers caused by partial rupture of the ventricular wall. Therapeutic management, including the timing for surgical approach, has not been standardized. We present a case series describing 4 patients. (Level of Difficulty: Intermediate.).

RESUMO

Ventricular septal rupture (VSR) is a rare but highly lethal (∼60%) mechanical complication of myocardial infarction (MI). Although surgical repair has been the gold standard to correct the structural anomaly, percutaneous closure of the defect may represent a valuable therapeutic alternative, with the advantage of immediate shunt reduction to prevent further hemodynamic deterioration in patients with prohibitive surgical risk. Nonetheless, catheter-based VSR closure has faced certain drawbacks that have hampered its application. We describe a clinical case of postinfarction VSR treated with a percutaneous closure device and discuss the procedure's failure mechanism. (Level of Difficulty: Intermediate.).

RESUMO

BACKGROUND: The purpose of this study was to assess the utility of a handheld device (HH) used during common daily practice and its agreement with the results of a standard echocardiography study (STD) performed by experienced sonographers and echocardiographer. METHODS: A prospective follow-up was conducted in an adult outpatient echocardiography clinic. Experienced sonographers performed the STD and an experienced echocardiographer performed the HH. STD included 2-dimensional images, Doppler and hemodynamics analysis. Hemodynamic assessment was not performed with the HH device because the HH does not include such technology. The images were interpreted by blinded echocardiographers, and the agreement between the reports was analyzed. RESULTS: A total of 108 patients were included; and the concordance for left ventricle (LV) ejection fraction (EF), wall motion score index, LV and right ventricle (RV) function, RV size, and mitral and aortic stenosis was excellent with κ values greater than 0.80. Wall motion abnormalities had good concordance (κ value 0.78). The agreement for LV hypertrophy, mitral and aortic regurgitation was moderate, and tricuspid and pulmonary regurgitation agreements were low (κ values of 0.26 and 0.25, respectively). CONCLUSIONS: In a daily practice scenario with experienced hands, HH demonstrated good correlation for most echocardiography indications, such as ventricular size and function assessment and stenosis valve lesion analyses.

RESUMO

Resumen El derrame pericárdico (DP) es una entidad frecuente en la práctica diaria, que puede ocurrir por un amplio rango de patologías. Los métodos por imágenes constituyen una herramienta diagnóstica clave en la evaluación del pericardio. El ecocardiograma transtorácico (ETT) se considera de primera línea por su costo-efectividad. La tomografía computarizada multicorte (TCMC), por su parte, representa un valioso complemento ante limitaciones del ETT y en la evaluación de urgencia del paciente con sospecha de DP. El objetivo del trabajo es mostrar la utilidad y rol de la TCMC, mediante la medición de densidades, para estimar la etiología del DP, ilustrado con casos de nuestra institución.

Abstract Pericardial effusion (PE) is a common entity in daily practice, which can occur due to a wide range of conditions. Imaging methods are a key diagnostic tool in the evaluation of the pericardium. Transthoracic echocardiogram (TTE) is the first line imaging method because of its cost-effectiveness. Multi-slice Computed Tomography (MSCT), on the other hand, represents a valuable complement to the limitations of TTE and in emergency evaluation of the patient with suspected PE. The objective of this review is to show the usefulness and role of the MSCT —through the measurement of densities— to estimate the etiology of PE, illustrated with cases of our Institution.

RESUMO

COVID-19 es una enfermedad infecciosa respiratoria aguda, causada por el SARS-CoV-2, un nuevo coronavirus, que se extendió rápidamente por todo el mundo, dando como resultado una pandemia. Los pacientes presentan un amplio espectro de manifestaciones clínicas, entre ellas, la miocarditis, y de manera alterna, algunos pacientes sin síntomas de enfermedad cardíaca, tienen anomalías en las pruebas, como elevación de la troponina y arritmias cardíacas en el electrocardiograma, o anomalías en las imágenes cardíacas. La patogenia del compromiso miocárdico no es clara, pero las dos principales teorías prevén un papel directo de la enzima convertidora de angiotensina 2, que funciona como el receptor viral, y una respuesta hiperinmune, que también puede conducir a una presentación aislada. El estándar de oro del diagnóstico es la biopsia endomiocárdica, la cual no está disponible en la mayoría de los escenarios. En esta revisión, se pretende brindar al lector pautas para identificar las manifestaciones clínicas, ayudas diagnósticas y manejo de los pacientes con sospecha de miocarditis por COVID-19

COVID-19 is an acute respiratory infectious disease caused by a new coronavirus, SARS-CoV-2 virus, that spread rapidly around the world, resulting in a pandemic. Patients present with a wide spectrum of clinical manifestations, including myocarditis, and alternately, some patients without symptoms of heart disease have abnormalities in tests, such as elevated troponin, arrhythmias in the ECG orabnormalities in cardiac imaging testing. The pathogenesis of myocardial involvement is not completely clear, but the two main theories suggest a direct role of the angiotensin-converting enzyme, which functions as the virus receptor, and a hyperimmune response, which can also lead to an isolated presentation. The gold standard for the diagnosis is the endomyocardial biopsy, which is not available in most settings. In this review, we intend to provide the reader with guidelines to identify the clinical manifestations, diagnostic tools, and management of patients with suspected COVID-19 myocarditis

RESUMO

Incidental findings are not uncommon in echocardiography. A transthoracic echocardiogram (TTE) of an adult woman with arterial hypertension showed a tubular structure with hyperechoic walls in the atrial side of the atrioventricular groove in apical views. Coronary computed tomography angiography correlated this finding with a retroaortic course of the anomalous circumflex artery (retroaortic anomalous coronary artery [RAC], benign coronary artery variant). Recently described as the RAC sign on TTE, practitioners should be aware of this finding to avoid mistaken it as artifacts, catheters/leads, or calcified mitral annulus.

RESUMO

BACKGROUND: Pericardial cysts are uncommon masses and are the third most common cystic mass of the mediastinum. The majority are asymptomatic, however, they can be associated with serious complications such as cardiac tamponade, bronchial obstruction, or even sudden death. CASE REPORT: An asymptomatic female patient, who was referred due to a chest radiograph showing cardiomegaly. The transthoracic echocardiogram showed an image consistent with a pericardial cyst, the diagnosis was confirmed with a magnetic resonance imaging. CONCLUSIONS: Pericardial cysts may appear as an incidental finding in the chest radiograph, either computed tomography scan or magnetic resonance imaging are useful to confirm the diagnosis.

ANTECEDENTES: Los quistes pericárdicos son masas poco comunes; ocupan el tercer lugar entre las masas mediastinales quísticas. La mayoría son asintomáticos, pero se pueden asociar a complicaciones serias como tamponade cardiaco, obstrucción bronquial e incluso muerte súbita. CASO CLÍNICO: Mujer asintomática con cardiomegalia en la tele de tórax a quien se diagnostica de forma incidental, mediante ecocardiograma, un quiste pericárdico gigante, que se corroboró por resonancia magnética. CONCLUSIONES: Los quistes pericárdicos pueden ser hallazgos incidentales en la radiografía de tórax. Tanto la tomografía computarizada como la resonancia magnética son estudios útiles para confirmar el diagnóstico.

RESUMO

Quadricuspid aortic valve is rare and requires surgery when symptomatic severe regurgitation/stenosis is present. Associated anomalous coronary ostia location demands accurate diagnosis to avoid intraoperative complications, and several imaging techniques have been used, with drawbacks of low sensitivity, radiation and contrast exposure. We report a pre-operative assessment using 3-dimensional echocardiography. (Level of Difficulty: Intermediate.).

RESUMO

Background: Echocardiographic cardiac parameters in the prone position are usually obtained with an esophageal probe. The feasibility of obtaining them by means of a transthoracic approach is unknown. Objective: Estimating the feasibility to obtain parameters of the right ventricle by transthoracic echocardiography in prone position on the subject. Methods: Pilot design of consecutive case series without cardiopulmonary disease. Demographic, vital signs and echocardiographic variables were defined in the ventral initial, prone and ventral final decubitus positions. The data are shown with averages and standard deviations, and frequencies and percentages according to the variable. The differences between the positions were calculated with ANOVA of repeated samples and adjustment of Bonferroni test. Intra-subject variability was obtained by the Bland-Altman procedure and its 95% confidence interval. Results: We studied 50 subjects, 44 (88%) males, age 30 ± 6 years and body mass index 25.65 ± 2.71 kg/m2. Tricuspid annular plane systolic excursion (TAPSE) and S'-wave were measured 100% of the time. The vital signs and echocardiographic variables according to the position had differences in: heart rate (74 ± 9 vs. 77 ± 9 vs. 75 ± 8 beats/min), partial oxygen saturation (94.40 ± 1.70 vs. 96.64 ± 1.79 vs. 95.32 ± 1.36%) and mean systemic blood pressure (65.33 ± 5.38 vs. 67.69 ± 6.31 vs. 65.29 ± 5.62 mmHg); TAPSE (19.74 ± 3.24 vs. 21.60 ± 2.97 vs. 19.44 ± 2.84 mm), mean difference (bias) 0 (2, -2.0) and S'-wave (13.52 ± 1.87 vs. 15.02 ± 2.09 vs. 13.46 ± 1.55 cm/s), mean difference (bias) -0.46 (1.21, -2.14) respectively. Conclusions: Obtaining right ventricle parameters by transthoracic ecocardiopraphy is feasible in the prone position.

RESUMO

Although coronavirus disease 2019 (COVID-19) manifests in most cases with respiratory symptoms, other presentations can occur. Direct damage to the cardiovascular system has been reported and recently, acute myocardial injury has been identified as a risk factor for mortality. Transthoracic echocardiography is a non-invasive tool that allows the detection of myocardial damage with validated markers (left ventricular ejection fraction and global longitudinal strain). Herein, we present the echocardiographic findings in four patients with COVID-19. All cases had acute respiratory distress syndrome (100%). Three out of four had elevated levels of creatine kinase and creatine kinase myocardial band. One case had ventricular concentric remodeling (25%). All cases (100%) had altered ventricular function: two had a reduced ejection fraction (50%) and, of those available for global longitudinal strain analysis, all had abnormal global longitudinal strain (100%). One case was found to have a tricuspid vegetation of 12 × 10 mm with no other manifestation of endocarditis. All of our cases had left ventricular dysfunction as assessed by echocardiography. One of our patients had a vegetation in the tricuspid valve. Two of our cases had a reduced ejection fraction. The importance of acute cardiac injury in COVID-19 has recently been established. A recent study found it to be an independent risk factor for mortality in patients with this disease. Information regarding echocardiographic characteristics of this population is scarce. Further research to elucidate the impact of these characteristics on morbidity and mortality is urgently needed.

To determine the usefulness of the FATE protocol (Focused Assessment with Transthoracic Echocardiography) in the evaluation of patients in shock admitted to the Intermediate Care Unit of the "University Hospital Antonio Maria Pineda" in Barquisimeto, Venezuela, during the period August-October 2019, Methods: A descriptive cross-sectional study was done, selecting 30 patients, with an average age of 56.86 ± 15.85 years; the most affected group was 71-80 years old (23.33%), with a predominance of the male sex (63.33%) Results: According to the classification of shock by Weil and Shubin, 50% were found to have distributive shock (all due to sepsis), 20% cardiogenic, 16.67% hypovolemic and obstructive 13.33%. The main echocardiographic findings were the presence of bilateral pleural effusion (33.33%), unilateral pleural effusion (30%) and pericardial effusion (23.33%). In addition, 26.67% presented pathological myocardial thickness, 33.33% increased RV-LV dimensions, 46.67% impaired ventricular systolic function; also, 70% of contractibility and 60% of pulmonary visualization were pathological. The qualitative value of the FATE protocol resulted in: 43.33% supported the available information, 26.67% added decisive information to the therapy, 23.33% added new information and 6.67% information was poor due to a bad US window. (Mortality at 7 days was 43.33%, being more frequent in patients with distributive shock (61.54%), followed by cardiogenic (23.08%) and obstructive (15.38%); there were no deaths due to hypovolemic shock. The qualitative values of the FATE protocol in patients with distributive shock who died, was that 37.5% In contrast, in 100% of those who died by cardiogenic and obstructive shock, the FATE protocol added decisive information to the therapy. Conclusion:The results demonstrate the importance of the FATE Protocol in the management of patients with shock(AU)

RESUMO

INTRODUCTION: Echocardiography represents one of the most important advances in the monitoring of critical patients. Initially available only in cardiovascular surgery, currently, there is transesophageal echocardiography (TEE) and transthoracic echocardiography (ETT) in non-cardiac surgery, for anesthesiologists. The advantages of ETT is a non-invasive tool, of lower cost than the transesophageal transducer and therefore more feasible to be overcrowded and available in the pavilion. OBJECTIVE: To evaluate the usefulness of TTE in patients with hemodynamic compromise during non-cardiac surgery. NATERIAL AND METHODS: In a prospective manner between April 2016 and September 2018, patients were studied who during their intraoperative period presented a compromise of their hemodynamic state, defined as an average blood pressure under 55 mm Hg, for more than 3 minutes and without response to the usual therapy based on vasopressors and volume. Each of these patients had a prospective protocol for focused ETT looking for the cause of this disorder, by a duly trained operator. RESULTS: 124 patients, with an average age of 67 years (range 42 to 93 years) were evaluated. In all cases, at least one echocardiographic window was obtained that allowed a diagnosis to be made and/or to guide the therapy. The main causes of hemodynamic compromise were hypovolemia (52%), poor left ventricular function (21%) and other causes such as pericardial effusion, suspected pulmonary thromboembolism, pulmonary pathology and suspected myocardial ischemia. DISCUSSION: The ETT could be a feasible tool to use in acute hemodynamic events, since it offers good quality windows that allow new decisions based on the diagnosis and also allows to guide the selected therapies. In addition, it has been shown to positively impact clinical behaviors in the perioperative period. ETT is a non-invasive monitor, reasonably easy to learn to use; In addition to directly visualizing cardiac structures, it allows differential diagnoses of the causes of intraoperative hypotension. The therapies can also be decided according to the echocardiographic images and control how they generate changes in the cardiac cavities and in the hemodynamic state of the patient.

INTRODUCCIÓN: La ecocardiografía representa uno de los más importantes avances en la monitorización de pacientes críticos. Inicialmente disponible sólo en cirugía cardiovascular, en la actualidad, se cuenta con ecocardiografía transesofágica (ETE) y ecocardiografía transtorácica (ETT) en cirugía no cardíaca, para los anestesiólogos. Las ventajas del ETT están en ser una herramienta no invasiva, de menor costo que el transductor transesofágico y, por lo tanto, más factible de ser masificada y estar disponible en pabellón. OBJETIVO: Evaluar la utilidad de ETT en pacientes con compromiso hemodinámico durante cirugía no cardiaca. MATERIAL Y MÉTODOS: En forma prospectiva entre abril de 2016 y septiembre del 2018, se estudiaron enfermos que durante su intraoperatorio presentaron compromiso de su estado hemodinámico, definido como una presión arterial media bajo 55 mm Hg, por más de 3 minutos y sin respuesta a la terapia habitual basada en vasopresores y volumen. A cada uno de estos enfermos se le realizó un protocolo prospectivo de ETT focalizado buscando la causa de esta alteración, por un operador debidamente entrenado. RESULTADOS: 124 pacientes, con edad promedio de 67 años (rango 42 a 93 años) fueron evaluados. En todos los casos se obtuvo al menos una ventana ecocardiográfica que permitió realizar un diagnóstico y/o guiar la terapia. Las principales causas de compromiso hemodinámico fueron hipovolemia (52%), mala función del ventrículo izquierdo (21%) y otras causas como derrame pericárdico, sospecha de tromboembolismo pulmonar, patología pulmonar y sospecha de isquemia miocárdica. La ETT podría ser una herramienta factible de utilizar en eventos hemodinámicos agudos, ya que ofrece ventanas de buena calidad que permiten tomar decisiones nuevas basadas en el diagnóstico y, además, permite guiar las terapias seleccionadas. Además, ha mostrado impactar de forma positiva las conductas clínicas en el perioperatorio. DISCUSIÓN: La ETT es un monitor no invasivo, razonablemente fácil de aprender a utilizar que además de visualizar de manera directa las estructuras cardíacas, permite realizar diagnósticos diferenciales de las causas de hipotensión intraoperatoria. Además, se puede decidir las terapias de acuerdo a las imágenes ecocardiográficas y controlar cómo éstas generan cambios en las cavidades cardíacas y en el estado hemodinámico del paciente.

RESUMO

Background: Transesophageal echo (TEE) bubble study is the current gold standard for patent foramen ovale (PFO) diagnosis, but it has the disadvantage of being semi-invasive and not exempted from risks. The aim of this study was to determine the accuracy of TTE compared to TEE for PFO diagnosis. Methods and results: a systematic review was done on Medline with the terms "transthoracic echocardiography, transesophageal echocardiography, patent foramen ovale, diagnosis" yielding published literature of the last ten years. The search was completed in february 2018. Of 715 articles, 10 were analyzed. The total of patients were 1268 (mean age of 47 years +/-14) with a global prevalence of PFO of 48%. The sensibility of ETT was 90 % (IC 95: 88 % - 92 %) and the specificity 92% (IC 95: 89 % - 94 %). The positive predictive value was 93% (IC 95: 90 % - 94 %) and the negative predictive value 89 % (IC 95: 87 % - 91 %). The area under the curve and Q index value were 0,97 and 0,93 respectively. The positive and negative likelihood ratio were 18,989 and 0,072 respectively. Conclusion: The ETT shows a good specificity and sensibility for PFO diagnosis with last generation equipments, contrast use and valsalva maneuver; according to the analyzed studies.
