Technical Details of Rechanneling of Obstructive Coronary Sinus Type of Totally Anomalous Pulmonary Venous Connection Using Malm's Coronary Sinus Cutback Technique and Left Atrial Augmentation: A Video Presentation

Abstract

Abstract Obstructive coronary sinus totally anomalous pulmonary venous connection although rare, is associated with a high mortality. A 2-month-old female child diagnosed with obstructive coronary sinus type of totally anomalous pulmonary venous connection and severe pulmonary arterial hypertension underwent complete unroofing of the coronary sinus by the “coronary sinus cutback technique” of Malm with left atrial augmentation and atrial septal fenestration.
