VISUALIZATION OF PULMONARY VEIN OBSTRUCTION BY PULMONARY-ARTERY WEDGEINJECTION AND DOCUMENTATION BY PRESSURE TRACINGS - REPORT OF ONE CASEWITH PERSISTENT WHEEZING FOLLOWING CORRECTION OF TOTAL ANOMALOUS PULMONARY VENOUS CONNECTION

A 21-month-old boy presented with persistent wheezing 16.5 months afte r cardiac surgery for supracardiac total anomalous pulmonary venous co nnection. He had presented at birth with cyanosis and at the age of 25 days, underwent initial cardiac surgery in the form of anastomosis of the pulmonary venous confluence to the left atrium. Non-invasive inve stigations including transthoracic and transesophageal echocardiograms revealed stenosis of the right pulmonary veins. Visualization and doc umentation of right pulmonary vein obstruction by pulmonary arterial w edge angiography and pressure tracings are presented.
