Article Abstract
Noncompaction myocardium (NCM) is a rare cardiac condition characterized by prominent trabeculation, associated with an increased risk of heart failure, arrhythmias, and embolism. We report the case of a 46-year-old man, smoker, with a family history of sudden cardiac death, who presented to the emergency department with progressive dyspnea. Echocardiography revealed dilated cardiomyopathy with severe biventricular dysfunction and marked apical trabeculation of the left ventricle. Coronary angiography showed a single coronary artery with anomalous origin of the right coronary artery from the mid-segment of the left anterior descending artery, without significant stenosis. Cardiac magnetic resonance imaging confirmed the NCM phenotype with a noncompacted-to-compacted myocardial ratio of 2.4. The simultaneous presence of NCM and single coronary artery is extremely rare in the literature. This phenotypic combination may suggest a common genetic predisposition and warrants targeted diagnostic investigations for optimal cardiovascular risk management.

Objectives: Coronary artery bypass grafting (CABG) using bilateral internal thoracic artery (BITA) conduits can achieve good outcomes for multivessel lesions. This study evaluated early angiographic patency and outcomes following off-pump CABG (OPCAB) using only in situ BITA and right gastroepiploic artery (rGEA) grafts.
Methods: This retrospective analysis included patients undergoing OPCAB using only in situ skeletonized BITA and rGEA grafts (July 2007 to March 2019).

Uric acid to HDL ratio (UHR) is a new measure of inflammation that has been widely used to study cardiovascular disease relationships. The aim of this study was to investigate the relationship between uric acid to HDL ratio and hypertension. We found that UHR was positively associated with hypertension prevalence in a nationally representative sample of U.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly. Its clinical course is typically severe in infancy, leading to left ventricular ischemia, cardiogenic shock, and high mortality without surgical intervention.We describe a rare case of a 3-year-old girl diagnosed with ALCAPA, showing extensive right-to-left collaterals, preserved left ventricular function, and minimal myocardial injury.

Purpose Of Review: Symptom relief is now recognized as the primary remit of percutaneous coronary intervention (PCI) in patients with stable coronary artery disease. The relationship between the nature of angina symptoms and the likelihood of successful symptom relief from PCI had not been systematically studied until recently.
Recent Findings: The ORBITA-2 symptom-stratified analysis found that while the severity and nature of symptoms were poorly associated with the severity of coronary disease, the nature of the symptoms powerfully predicted the efficacy of PCI in relieving angina.

Single coronary ostium and intramural coronary artery variations in patients with transposition of the great arteries significantly increase the mortality and morbidity after arterial switch operation (ASO). In these patients, the classic coronary button implantation may cause kinking or twisting of the coronary artery which can cause coronary insufficiency. This case series presents two patients, a 15-month-old girl with transposition of the great arteries and a 10-month-old boy with a Taussig-Bing anomaly.
