Acute and Long-Term Scar Characterization of Venous Ethanol Ablation in the Left Ventricular Summit.

Background: Venous ethanol ablation (VEA) can be effective for ventricular arrhythmias from the left ventricular summit (LVS); however, there are concerns about excessive ablation by VEA.

Objectives: The purpose of this study was to delineate and quantify the location, extent, and evolution of ablated tissue after VEA as an intramural ablation technique in the LVS.

Methods: VEA was performed in 59 patients with LVS ventricular arrhythmias.

Substrate Ablation by Multivein, Multiballoon Coronary Venous Ethanol for Refractory Ventricular Tachycardia in Structural Heart Disease.

Background: Ablation of ventricular tachycardia (VT) in the setting of structural heart disease often requires extensive substrate elimination that is not always achievable by endocardial radiofrequency ablation. Epicardial ablation is not always feasible. Case reports suggest that venous ethanol ablation (VEA) through a multiballoon, multivein approach can lead to effective substrate ablation, but large data sets are lacking.

Cor Triatriatum Dexter: An Innocent Bystander.

Cor triatriatum dexter is a rare congenital heart defect with a varied clinical presentation ranging from asymptomatic to right heart failure. Accurate diagnosis is imperative as it may affect clinical decision making. We present a multimodality imaging assessment of cor triatriatum dexter in a 70-year-old woman with severe tricuspid regurgitation.

Arrhythmias in COVID-19.

The coronavirus pandemic remains a major public health burden with multisystem disease manifestations. There has been an ongoing global effort to better understand the unique cardiovascular manifestations of this disease and its associated arrhythmias. In this review, we summarize the current data on incidence and outcomes of arrhythmias in the acute and convalescent period, possible pathophysiologic mechanisms, and medical management.

Large Cell Neuroendocrine Cervical Carcinoma: A Case Report.

We herein report a unique case of a large cell neuroendocrine tumor in a female presenting with right upper quadrant pain. She was found to have multiple metastatic lesions in the liver noted on imaging and underwent workup for malignancy of unknown origin. The initial differential diagnoses included gastrointestinal, urothelial, genital, or breast primary sites.

A Rare Case of Infective Endocarditis Caused by Gemella haemolysans.

Gemella haemolysans is a gram-positive coccoid, facultative anaerobe of the mucous membranes. In rare cases, it has been identified as an opportunistic pathogen in the development of endocarditis. Here, we describe a case of infective endocarditis in a patient with a bicuspid aortic valve.

Loperamide Mimicking Brugada Pattern.

Brugada syndrome is an inherited arrhythmia that increases a patient's risk of sudden cardiac death. Certain pharmacologic agents may induce a transient Brugada pattern on surface electrocardiogram (EKG). One of these is loperamide, an over-the-counter agent commonly used to manage diarrhea.

Building an Adult Congenital Heart Program: Critical Components and Important Allies.

Purpose Of The Review: The purpose of this review is to illustrate specific challenges and opportunities in the building of an adult congenital heart disease (ACHD) program and to highlight critical components and important allies.

Recent Findings: With more than 1.4 million adults with congenital heart disease in the USA alone, access to specialized, compassionate, high-quality comprehensive care requires a shift toward more aggressive expansion of ACHD care, especially in the context of sparse ACHD provider representation in the vast majority of adult medical centers.

A Rare Catch in a Nonhealing Wound.

Introduction: Mycobacterium smegmatis is a common microbe found in soil, dust, and water that rarely causes infections in humans.

Case Report: A 45-year-old man with a past medical history of hypertension presented with a nonhealing surgical wound in his anterior chest wall, measuring 0.5 cm x 0.
