Congenital Absence of the Left Circumflex Artery With Super-Dominant Right Coronary Artery: Extremely Rare Coronary Anomaly.

Among the congenital anomalies of the coronary arteries, absent left circumflex artery (LCX) defect is extremely rare. Only a few cases have been reported in the literature. We report a case of a 48-year-old female who presented with a 4-month history of exertional chest pain with positive stress (treadmill) test.

"Superdominant" Left Anterior Descending Artery Continuing as Posterior Descending Artery: Extremely Rare Coronary Artery Anomaly.

The posterior descending artery (PDA) supplying the posterior one-third of the inter-ventricular septum usually arises from the right coronary artery (RCA) or the left circumflex artery (LCX). PDA arising from the left anterior descending artery (LAD) is an extremely rare anomaly. Here we report a rare type of left dominant circulation in which a large LAD is continuing as PDA after winding round the apex in the presence of a diminutive RCA.

Thrombolysis Is an Effective and Safe Therapy in Stuck Mitral Valves With Delayed Presentation as Well as Hemodynamically Unstable Patients: A Single Centre Study.

Background: Thrombosis is a complication of prosthetic valves on oral anticoagulants which is associated with significant morbidity and mortality. A re-operation carries a substantial risk, with mortality rate from 10% to 15% in selected series, which may be 2- or 3-folds higher in critically ill patients. This study conducted in a tertiary care cardiology unit aimed to evaluate the effectiveness and safety of thrombolytic therapy in stuck mitral bileaflet heart valves.

Acute Respiratory Distress Syndrome Caused by Mercury Inhalation: A Case Report.

Inhalation of mercury vapor is an uncommon cause of acute respiratory distress syndrome. It may go unnoticed if appropriate environmental/occupational history is not taken. A 2-year-old child presented with severe respiratory distress and progressed to develop acute respiratory distress syndrome, necessitating high-pressure mechanical ventilation.
