RESUMO
BACKGROUND: Predictors of permanent pacemaker implantation (PPMI) after self-expanding transcatheter aortic valve implant (TAVI) were described. Is unknown if PPMI predictors remain in the era of high implants using the cusp overlap (COP). METHODS: Single-center, prospective, consecutive case series of patients undergoing self-expanding TAVI with the COP approach. The status of PPMI and other clinical events were ascertained at 30 days. RESULTS: A total of 261 patients were included (84% with Evolut, n = 219). Implant depth >4 mm was infrequent (13.8%). TAVI depth (OR 1.259; p = 0.005), first or second-degree auriculo-ventricular block (OR 3.406; p = 0.033), right-bundle (OR 15.477; p < 0.0001), and incomplete left-bundle branch block (OR 7.964; p = 0.036) were found to be independent predictors of PPMI. The risk of PPMI with deep implant and no electrical disturbances was 3%, and 0% with high implant and no prior electrical disturbances. Those who received PPMI had no statistically significant increased risk of death, myocardial infarction, stroke, bleeding events, or vascular complications at 30 days, but longer hospital stay (mean difference 1.43 days more, p = 0.003). CONCLUSIONS: Implant depth and prior conduction abnormalities remain the main predictors of PPMI using self-expanding TAVI in the COP era. Patients with high implants and no prior conduction abnormalities may be candidates for early discharge after uneventful self-expanding TAVI, while the rest may need inpatient monitoring regardless of achieving a high implant. The need for PPMI was associated with longer hospital stays.
RESUMO
Background: Periprocedural myocardial injury (PPMI) frequently occurs after transcatheter aortic valve implantation (TAVI), although its impact on long-term mortality is uncertain. Methods: We performed a pooled analysis of Kaplan-Meier-derived individual patient data to compare survival in patients with and without PPMI after TAVI. Flexible parametric models with B-splines and landmark analyses were used to determine PPMI prognostic value. Subgroup analyses for VARC-2, troponin, and creatine kinase-MB (CK-MB)-defined PPMI were also performed. Results: Eighteen observational studies comprising 10,094 subjects were included. PPMI was associated with lower overall survival (OS) after two years (HR = 1.46, 95% CI 1.30-1.65, p < 0.01). This was also observed when restricting the analysis to overall VARC-2-defined PPMI (HR = 1.23, 95% CI 1.07-1.40, p < 0.01). For VARC-2 PPMI criteria and VARC-2 troponin-only, higher mortality was restricted to the first 2 months after TAVI (HR = 1.64, 95% CI 1.31-2.07, p < 0.01; and HR = 1.32, 95% CI 1.05-1.67, p = 0.02, respectively), while for VARC-2 defined CK-MB-only the increase in mortality was confined to the first 30 days (HR = 7.44, 95% CI 4.76-11.66, p < 0.01). Conclusion: PPMI following TAVI was associated with lower overall survival compared with patients without PPMI. PPMI prognostic impact is restricted to the initial months after the procedure. The analyses were consistent for VARC-2 criteria and for both biomarkers, yet CK-MB was a stronger prognostic marker of mortality than troponin.
RESUMO
BACKGROUND: Cardiac magnetic resonance (CMR) allowed to precisely identify the substrate in scar-related ventricular tachycardia (VT). New software has been developed to define the 3D scar and corridors to help VT ablation by integrating the scar and electroanatomical mapping (EAM). The objective of this study is to evaluate the results of VT ablation aided by the integration of EAM and CMR software processed scar. METHODS: We selected patients that underwent VT ablation with the integration of EAM and CMR processed using ADAS software and imported to the CARTO system using VTK file format. RESULTS: From 2019 to 2021, eight patients (mean age 63 ± 4.4, 62.5% male; EF 47 ± 12%) underwent CMR-aided VT ablation. Mean procedural time was 281 ± 77 min. There was of 9 ± 4.4 epicardial and 7.9 ± 4.3 endocardial bulls eye segments with at least 2 g of border zone or core scar. In a median follow-up time of 532 days (Q1: 284, Q3: 688), three patients (37.5%) presented VT recurrence, all three underwent a second procedure, with no VT recurrence on the follow-up. No patient died in the follow-up. CONCLUSION: CMR aided is ablation is feasible and effective in patients with scar related VT.

The seismic impact of transcatheter interventions is rocking the spectrum of structural heart disease (SHD) treatment, with the compelling and attractive appeal of minimally invasive procedures and fast-track discharge. The trend is relentless and continual innovation comes to our doors nearly on a daily basis. Litwinowicz and colleagues describe their trailblazing experience in 223 consecutive patients in whom they performed left atrial appendage occlusion via the percutaneous route. All interventions were performed by surgeons, who had undergone pretraining in a simulation model. Soon thereafter, they were able to achieve outcomes that were comparable with those obtained by experienced interventional cardiologists. The unique surgeons' training and skills in open-heart surgery make their contribution to perfection and safety of SHD treatment, which are potentially exceptional and distinctive. Extrapolating for the entire field of SHD, which is blossoming ahead, the message to be conveyed is that cardiac surgeons must be trained and embrace every aspect of SHD.

Resumen La red sanitaria en el entorno de la pandemia por COVID-19 ha sufrido un gran impacto. La reorganización de la misma ha sido fundamental para poder atender la emergencia sanitaria, y en algunos países, ha sido incluso de forma abrupta. La atención oportuna de las enfermedades cardiovasculares continúa siendo una prioridad por la elevada mortalidad que ella implica especialmente en estadios muy avanzados de la enfermedad, y la modificación en la atención médica en el contexto actual no puede afectar la asistencia de patologías cardíacas. Los programas de cardiología estructural y cirugía cardíaca en nuestro país se han consolidado y crecido en los últimos años, ofreciendo múltiples procedimientos percutáneos o mínimamente invasivos para cardiopatías de alta morbimortalidad. La continuación de los mismos, a pesar de las dificultades por la pandemia, es necesaria en ciertos casos. Este documento reúne las principales recomendaciones basados en textos internacionales al respecto, para mantener el cuidado cardiovascular en Costa Rica pese al COVID-19 en el ámbito de la cardiopatía estructural.
Abstract The health system in the context of the COVID-19 pandemic has suffered a great impact. Thus, organization has been essential in maintaining the ability to respond to the health emergency, and in some countries, it has even been abrupt. The treatment of cardiovascular diseases continues to be a priority, and the modification of medical care in the current context cannot affect the timely procedures of cardiac pathologies. The structural cardiology and cardiac surgery programs in our country have been consolidated and grown in recent years, offering multiple percutaneous or minimally invasive procedures for heart disease with high morbidity and mortality. Their continuation, despite the difficulties caused by the outbreak, is necessary in certain cases. This document brings together the main recommendations based on international guidelines and experts opinions in this regard, to maintain cardiovascular care in Costa Rica despite COVID-19.

Objective: Cardiac sympathetic denervation (CSD) using video-assisted thoracoscopy is a therapeutic alternative for cardiac arrhythmias refractory to conventional treatment in patients with ventricular structural heart disease, mainly due to ischemia, and in patients with hereditary conditions associated with sudden death such as long QT syndrome. In general, it is performed in cases with recurrent episodes of ventricular tachycardia or electrical storm, in spite of conventional treatment. The objective of this study is to show the experience of this institution with DSCI in refractory patients to conventional management and the results derived from its application. Methods: This was an observational retrospective study. The records of patients with a history of ventricular arrhythmias treated in our center with pharmacological treatment, catheter ablation, or implantation of an implantable cardioverter-defibrillator (ICD), who underwent video-assisted CSD were analyzed and described. Results: A total of six patients were included in the study. Patients with structural heart disease were the most frequent, median age was 56 ± 16 years; 67% were male. The procedure evolved without complications in any of the patients and an overall significant improvement was observed. A 24-month follow-up was conducted; two patients had recurrence episodes presenting as slow ventricular tachycardia without severe symptoms and a third patient presented an episode of ventricular fibrillation aborted by the ICD. Conclusion: Video-assisted CSD should be considered as a treatment option for patients with potentially dangerous arrhythmias that do not respond to conventional treatment, especially in recurrent ventricular tachycardia.
Objetivo: La denervación simpática cardiaca izquierda (DSCI) por toracoscopia se ha convertido en una alternativa terapéutica para el manejo de arritmias cardíacas refractarias al tratamiento convencional en pacientes con cardiopatía estructural, principalmente isquémicos, y enfermedades hereditarias asociadas con muerte súbita como el síndrome de QT largo. Generalmente se realiza en quienes manifiestan episodios recurrentes de arritmias ventriculares o incluso tormenta eléctrica a pesar del tratamiento convencional. El objetivo de este estudio es mostrar la experiencia de esta institución con la DSCI en pacientes refractarios al manejo convencional y los resultados derivados de su aplicación. Métodos: Se revisaron los registros de 6 pacientes con antecedente de arritmias ventriculares tratados previamente con medicamentos y en algunos casos con ablación con catéter y la mayoría con desfibrilador automático implantable, que fueron llevados DSCI por toracoscopia video-asistida (VATS). Resultados: La principal enfermedad de base fue la cardiopatía estructural, la indicación más prevalente fue tormenta arrítmica incontrolable, la edad promedio fue de 56 ± 16 años, el 67% de los individuos fueron hombres. Este procedimiento no mostró complicaciones en ninguno de los pacientes y se encontró mejoría sintomática en todos los casos. Se realizó seguimiento por 24 meses; dos pacientes tuvieron recurrencias por taquicardia ventricular lenta sin síntomas severos y uno por fibrilación ventricular. Conclusion: La DSCI por VATS debe considerarse como opción terapéutica para pacientes con arritmias de difícil manejo.

OBJECTIVE: We sought to compare the new transcatheter aortic valve replacement (TAVR) device ACURATE neo (ACT) with the already established CoreValve (MCV) and SAPIEN XT (SXT) for the treatment of severe aortic stenosis (AS). BACKGROUND: Very few data on TAVR devices are available beyond MCV and SAPIEN and there is no previous study comparing ACT with MCV and SXT. METHODS: We prospectively evaluated consecutive patients who underwent transfemoral TAVR for the treatment of severe AS. Clinical outcomes were reported following Valve Academic Research Consortium 2 (VARC-2) criteria. RESULTS: A total of 162 patients (ACT n = 49, MCV n = 56, SXT n = 57), were included. MCV group had higher valve embolization/migration rates (ACT none; MCV 9%; SXT 2%; P = 0.034) causing lower device success rates (ACT 98%; MCV 86%; SXT 95%; P = 0.043). At 30 days, there was no significant difference in all-cause mortality (P = 0.22), cardiovascular mortality (P = 0.20), periprocedural myocardial infarction (P = 0.40), stroke (P = 0.64), major vascular complications (P = 0.48), life-threatening bleeding (P = 0.29), acute kidney injury stage 2/3 (P = 0.69), or VARC-2 composite early safety endpoints (P = 0.21). MCV group had higher rates of new permanent pacemaker implantation (ACT 6%; MCV 25%; SXT 11%; P = 0.013). Follow-up echocardiography showed no significant difference in aortic valve mean pressure gradient (P = 0.73) or moderate/severe aortic regurgitation (P = 0.19) between groups. CONCLUSIONS: In a "real world" registry, ACT compared favorably against the well-studied SXT and MCV devices in both safety and efficacy. MCV implantation was associated with lower device success rates and higher rates of new permanent pacemaker implantation. © 2016 Wiley Periodicals, Inc.

Complications of transseptal puncture are significant and potentially life threatening. Aortic perforation is one of these complications and it needs to be repaired immediately. We report the case of a 48-year-old female with a history of rheumatic mitral valve disease. She underwent three previous mitral valve replacements. Her last echocardiogram reported an anterolateral leak in the mitral prosthesis. Catheterization was performed. During the procedure, when attempting to perform transseptal puncture, catheterization was complicated by a forcefully puncture of the aortic root by the Brockenbrough needle followed by an immediately advancement of an 8-Fr Mullins sheath. We decided to leave the 8-Fr sheath in the aortic root recognizing the danger of removing the sheath and finally we advanced a 6/4 mm Amplatzer ductal occluder (ADO I) through the Mullins sheath and under fluoroscopy and TEE guidance we achieved a successful deployment of the device and closure of the perforation. Subsequently, the paravalvular leak was closed with an Amplatzer Vascular Plug (AVP III 10/5 mm). There are only three cases of a similar technique for the same injury in which the authors describe successful closing of aortic perforation with percutaneous closure devices. Our case is the first described during a mitral paravalvular leak closure. It is also the first to describe a different technique of leaving the Mullins sheath in the aortic root and advancing the Amplatzer device through it to achieve successful closure of the aortic perforation. We preferred the percutaneous closure over open-heart repair. © 2015 Wiley Periodicals, Inc.
