RESUMEN
Venous thromboembolism is a very common presentation in the hospital setting. In patients with high-risk pulmonary embolism (PE) or PE and hemodynamic instability, systemic thrombolytic treatment is generally indicated. In those with contraindications to systemic thrombolysis, catheter-directed local thrombolytic therapy and surgical embolectomy are currently considered. In particular, catheter-directed thrombolysis (CDT) is a drug delivery system coupling the endovascular drug administration nearby in the thrombus and the local facilitating effect of ultrasounds. The applications of CDT are currently debated. Here we provide a systematic review of the clinical utilization of CDT.
RESUMEN
Background: The purpose of this study is to further investigate the leading causes of readmission at 30 days in heart failure exacerbation patients, along with associations to mortality and intensive care unit (ICU) admissions. Methods: A retrospective data analysis was performed on a total of 33,400 patients between January 1, 2016, and December 31, 2020. The primary endpoints were to determine whether guideline-directed medical therapy (GDMT), length of stay, and time to first diuretic affect readmission rates. Secondary endpoints include time to first chest X-ray, time to first echocardiogram, administration of intravenous fluids, diet, presence of cardiology consult, and ICU admission. Results: Patients who received GDMT had decreased likelihood of mortality (odds ratio (OR): 0.518; 95% confidence interval (CI): 0.394 - 0.682; P < 0.001). Patients who had an echocardiogram done within 1 day of admission had less likelihood of death (OR: 0.606; 95% CI: 0.483 - 0.759; P < 0.001). In addition, patients who had a cardiac diet during their hospitalization were 0.632 times less likely to experience mortality (95% CI: 0.502 - 0.797; P < 0.001). Patients that received their first intravenous diuretic 2 h or more after admission were 1.290 times as likely to be readmitted within 30 days (95% CI: 1.018 - 1.634; P = 0.035). In addition, patients that did not receive intravenous diuretics were even more likely to be readmitted within 30 days (OR: 1.555; 95% CI: 1.237 - 1.955; P < 0.01). Patients who were treated with GDMT had a decreased chance of being readmitted within 30 days (OR: 0.781; 95% CI: 0.647 - 0.944; P = 0.01). Conclusions: This study stresses the importance of initiating GDMT, cardiac diet, diuretics, and echocardiogram in timely manner.
RESUMEN
Despite the advancements in the prevention and treatment of cardiovascular diseases, sudden cardiac death (SCD) remains a leading cause of mortality and is accountable for approximately 15% of the total mortality in the USA. The prognosis after sudden cardiac arrest (SCA) varies significantly and depends largely on the underlying etiology and the rapidity and efficiency of resuscitation; however, the outcome remains poor for most of the patients. The main culprits for SCD are coronary heart disease (CHD) and heart failure with reduced ejection fraction (HFrEF). Patients with HFrEF and an ejection fraction (EF) of less than 35% are considered for an implantable cardioverter-defibrillator (ICD) placement if the EF does not improve. A wearable cardioverter defibrillator (WCD) commonly known as a life-vest is sometimes used as a bridging modality until an ICD is implanted. The indication and utility of WCD is still a controversial topic. The purpose of this article is to provide an up-to-date comprehensive review of literature for WCD utilization.
RESUMEN
Serratia marcescens (S. marcescens) is a gram negative bacterium rarely associated with cases of infective endocarditis (IE). Involvement of three cardiac valves, as evidenced by echocardiography, is uncommon as well. S. marcescens IE and tri-valvular endocarditis have been rarely described in literature. We report a unique case of S. marcescens tri-valvular IE in a 42-year-old female with sudden altered mental status and no underlying structural heart disease complicated by embolic infarcts in both cerebral and cerebellar hemispheres, and a sub-arachnoid hemorrhage. To our knowledge, this is the first reported case of tri-valvular S. marcescens IE. We believe this report will add to the growing literature of rare bacterial IE and considering this in the differential in the right clinical scenario.
RESUMEN
Atrial fibrillation (a-fib) is one of the most frequently encountered and studied arrhythmias in medicine. The presence of A-fib in the post-operative period of coronary artery bypass graft (CABG) surgery is of particular concern for clinicians as this presents risks of post-operative stroke, hospital readmission, or anticoagulation dilemmas depending on the patient's comorbidities. In this case study, we present 5 patients who were treated with dronedarone prior to undergoing open heart procedures. We subsequently followed each patients clinical course paying close attention for any evidence of post-operative a-fib.
RESUMEN
Catheter ablation is a common procedure performed in patients with atrial fibrillation. While some commonly known complications include perforation, thromboembolism, pericardial effusion, and cardiac tamponade, gastroparesis is a less reported post-procedural complication. We present a case of a 66-year-old female admitted with intractable nausea and vomiting six weeks post-ablation. After ruling out the common causes of gastroparesis, a gastric emptying study was done, which confirmed the diagnosis of gastroparesis. Physicians should have a high degree of suspicion for vagus nerve damage in post-ablation patients that presents with unexplained persistent gastrointestinal (GI) symptoms to facilitate a better outcome.
RESUMEN
Infective endocarditis (IE) occurs when bacterial or fungal pathogens enter the blood and attach to the endocardium. Right-sided endocarditis is usually associated with intravenous drug use (IVDU), intracardiac devices, and central venous catheters. There is more data published about left-side endocarditis when compared to right-sided endocarditis. Tricuspid valve infective endocarditis (TVIE) accounts for 5%-10% of IE, and of those cases, roughly 10% are complicated by conduction deficits due to inflammatory edema, myocarditis, and abscess formation. Tricuspid valve (TV) surgical repair carries its own risks, one of which includes the development of conduction abnormalities. Here, we review the current data of TVIE complicated by heart block after tricuspid valve replacement. Also, we present a case of a 21-year-old IVDU female who presented with tricuspid valve endocarditis, subsequently underwent tricuspid valve replacement, and developed a heart block.
RESUMEN
Concomitant arterial and venous thrombosis is an infrequent event often associated with malignancy, hyperhomocysteinemia, and thrombophilic conditions. Some overlapping pathophysiology mechanisms suggest an association between arterial and venous thrombosis. It is reported that thrombosis in the arterial and venous systems develops through distinct mechanisms affecting inflammatory and oxidative pathways. Recently, the aromatase inhibitors have moved to the forefront of adjuvant hormonal therapy, however, the adverse effects of these agents are not yet fully understood. It is generally accepted that tamoxifen, but not aromatase inhibitors, is associated with an increased risk of thrombosis in women with breast cancer. Here, we report an unusual case of an 87-year-old female on anastrozole therapy with aortic thrombus extending into the left subclavian artery with associated diffuse venous thromboembolism (VTE). An 87-year-old-female with a history of breast cancer in remission, obesity, hypertension, and dyslipidemia presented to the emergency department with new onset of left arm weakness and tingling sensation. Vital signs showed respiratory rate of 20 per minute, oxygen saturation of 95% on 3 L of oxygen via nasal cannula, blood pressure of 150/79 mmHg, and pulse 81 beats per minute. Computed tomography angiography (CTA) neck showed an aortic thrombus extending into the left subclavian artery and bilateral pulmonary emboli (PE). Doppler ultrasound of the lower extremities showed a deep venous thrombosis (DVT) in the left lower extremity. Echocardiography showed no patent foramen ovale. She was started on continuous heparin infusion and subsequently transitioned to an oral anticoagulation medication upon discharge. Symptomatic ischemic lesions of the upper extremity due to thrombosis of the subclavian artery are extremely rare, occurring in less than one percent of the population. While this patient had a history of early-stage breast cancer, she was on adjuvant anastrozole therapy with no evidence of recurrence or further tumor burden as per her outpatient oncologist, who also followed her during her hospital stay. She also had no prior history of thromboembolic disease or clotting disorders. Her only risk factors appear to be her age and her obesity (with a BMI over 30). Nevertheless, the extent of thromboembolism seen in this patient is greater than that might be expected with these factors. This case highlights a concomitant rarity of arterial and venous thrombosis. Also, there are not enough studies on anastrozole effect on thromboembolism. Given these risk factors, we recommend a high degree of suspicion for VTE in patients who are on anastrozole therapy.
RESUMEN
Anomalous left coronary artery arising from the pulmonary artery (ALCAPA) syndrome is a very rare congenital heart disease with an incidence of one in 300,000 and a high rate of mortality early in life if left untreated. Adult-type ALCAPA presents when significant collaterals develop from the right coronary artery (RCA) to the left coronary artery (LCA). Even with the collaterals, chronic sub-endocardial ischemia occurs in most cases, and patients die from sudden cardiac death. Here we present a case of a 38-year-old female who lived an active and healthy life and presented with chest pain and palpitations. Initial electrocardiography (EKG) showed atrial fibrillation with rapid ventricular response. Although initial cardiac enzymes were negative and there were no ischemic EKG changes, troponins became elevated over the course of the hospital stay and the patient underwent a left heart catheterization. Results revealed a dilated RCA extending to the left ventricle and an anomalous left main originating from the pulmonary artery with complete occlusion. The patient received medical management for acute coronary syndrome, including heparin infusion for 48 hours, aspirin, metoprolol, and atorvastatin. She was referred to a tertiary care facility for surgical correction of anomaly of the coronary arteries. The next day, the patient arrived in the emergency department with an acute onset of speech difficulty and left-sided weakness. A brain CT without contrast showed hematoma in the right frontal lobe. The patient underwent surgical evacuation of the hematoma with marked improvement of her weakness. The patient recovered after a successful surgical repair involving translocation of the left main coronary artery to the aorta. It has been reported that ALCAPA should be considered in a young adult with dilated cardiomyopathy and mitral regurgitation (MR). Other common presentations include acute myocardial infarction, angina, and dyspnea on exertion. Sudden cardiac death is not uncommon; however, it tends to decrease with age of diagnosis. Interestingly, our patient was known to have MR with regular follow-up at the cardiology clinic for years. Echocardiogram never showed any abnormalities other than MR. She never received further workup to address the reason of MR, although she has no underlying chronic conditions that can explain it. In relatively young patients with a healthy lifestyle presenting with chest pain, a broader look at etiologies should be considered. We would like to emphasize the importance of looking up for possible coronary artery disease, especially in young individuals.
RESUMEN
Pneumopericardium (PP), pneumomediastinum (PM), epidural pneumatosis, and subcutaneous emphysema (SE) are identified by the existence of free air or gas in the associated spaces. They are normally self-limited unless tension pneumothorax, tension PM, cardiac herniation, air tamponade, and esophageal rupture accompany these disorders. PM and PP can be divided into "spontaneous" or "secondary" based on the preceding etiologies. Spontaneous PM is often extremely rare and benign in course. On the other hand, secondary PM and PP are more common and result from intrathoracic infections, trauma-related esophageal rupture, or tears along the tracheobronchial tree. Our patient presented four days after a fall from a chair and was found to have suffered a stroke, with complete left side paralysis. CT imaging on arrival was significant for PM, PP, and SE, the cause of which remains unclear. The patient was diagnosed with COVID-pneumonia approximately six months prior to presentation. As the COVID-19 pandemic has evolved, several scientific papers have been published reporting infected patients who had developed spontaneous PT, PM, or even PP, in the absence of invasive mechanical ventilation. Is it possible that the spontaneous findings in our patient were COVID-related? Or could the spontaneous PP, PM, and SE be a sequel to the trauma of her fall from a chair? The answer still remains unclear.
