Background The aim of this study was to determine the frequency of coronary artery anomalies (CAAs) in Tetralogy of Fallot (TOF) patients undergoing computed tomography (CT)-angiography in a tertiary care hospital. Methodology In this observational study, we included consecutive TOF patients undergoing CT-angiography without prior history of cardiac surgery or congenital heart disease. CAAs were defined based on either origin or course of the artery. Results Out of 441 TOF patients, the prevalence of CCAs was 3.6% (16), of which 13 were below 18 years of age. Anomalous left main artery was observed in six (1.4%) patients, followed by left anterior descending artery and right coronary artery, observed in four (0.9%) patients each, and two (0.5%) patients had a single coronary artery originating from the left coronary cusp with an interarterial course. Conclusions CAAs were observed in a significant number (3.6%) of TOF patients. A CT-angiographic assessment before surgical correction would help identify the exact anatomy for better surgical planning to minimize complications.

Background And Aims: Vitamin D binding protein (DBP) serves a dual function as a vitamin D carrier and actin scavenger. Free DBP is present in high concentrations in serum, while a smaller pool is bound to lipoproteins like HDL and VLDL. The role of DBP's interaction with lipoproteins remains unclear.

Background: Rates of premature coronary artery disease (CAD) are stagnant, and the prevalence of cardiovascular risk factors in young and middle-aged adults is increasing. Lipid-lowering therapy (LLT) is effective in preventing CAD but is underutilized in younger patients. The reasons for and consequences of this underutilization are not fully understood.

Background: Atrial infarction is a complication of myocardial infarction with ventricular infarction; however, isolated atrial infarction (IAI) has rarely been reported. Herein, we report a case of IAI associated with sick sinus syndrome and atrial fibrillation (AF).
Case Summary: An 83-year-old woman was brought to the emergency department with a complaint of general malaise.
