Swiss Cheese Heart: A Tale of Multiple Valve Perforations.

Gerbode defect, an anomalous connection between the left ventricle and right atrium, is often congenital but can be acquired or iatrogenically formed. We present an exceedingly rare case of this defect associated with multiple valve perforation in an otherwise healthy patient with bicuspid aortic valve and endocarditis.

Dipyridamole-induced STEMI: case report and review of the literature.

Dipyridamole nuclear myocardial perfusion imaging is a safe and useful modality for assessing myocardial ischemia. It is the modality of choice for cardiac risk stratification in patients who are unable to exercise. Intravenous dipyridamole causes coronary vasodilation and may result in heterogeneity of coronary blood flow in significant coronary artery disease.

Left Bundle Branch Pacing: A Paradigm Shift in Physiological Pacing for Patients With Atrioventricular Block and Preserved Left Ventricular Systolic Function, A Systematic Review and Meta-analysis.

His-Purkinje conduction system pacing (HPCSP) via His bundle pacing (HBP) and Left Bundle Branch Pacing (LBBP) offer a physiological approach to pacing by restoring normal ventricular activation. This meta-analysis compares the feasibility, outcomes, and success rates of HBP and LBBP in patients with atrioventricular block (AVB) and preserved left ventricular function. A systematic search identified studies comparing LBBP with HBP in AVB patients with preserved systolic function.

Polypill Therapy in Cardiovascular Disease: A Meta-Analysis of Randomized Controlled Trials.

The effectiveness of polypill therapy in the prevention and treatment of cardiovascular disorders is still unclear. This meta-analysis aimed to assess the efficacy of polypill therapy in reducing cardiovascular risk factors. We conducted a systematic search of PubMed, Cochrane CENTRAL, SCOPUS, and Google Scholar for randomized controlled trials (RCTs) that evaluated polypill therapy for cardiovascular diseases, hypertension, or dyslipidemia.

Efficacy of Hydroxychloroquine and Tocilizumab in Patients With COVID-19: Single-Center Retrospective Chart Review.

Background: During the initial phases of the COVID-19 pandemic, there was an unfounded fervor surrounding the use of hydroxychloroquine (HCQ) and tocilizumab (TCZ); however, evidence on their efficacy and safety have been controversial.

Objective: The purpose of this study is to evaluate the overall clinical effectiveness of HCQ and TCZ in patients with COVID-19. We hypothesize that HCQ and TCZ use in these patients will be associated with a reduction in in-hospital mortality, upgrade to intensive medical care, invasive mechanical ventilation, or acute renal failure needing dialysis.

Meta-Analysis Comparing the Safety and Efficacy of Prasugrel and Ticagrelor in Acute Coronary Syndrome.

Prasugrel and ticagrelor are preferred over clopidogrel for patients with acute coronary syndrome who underwent percutaneous coronary intervention. We sought to determine the relative merits of 1 agent over the other. Multiple databases were queried to identify relevant randomized control trials (RCTs) and observational cohort studies.
