Visualization of pulmonary vein obstruction by pulmonary artery wedge injection and documentation by pressure tracings: report of one case with persistent wheezing following correction of total anomalous pulmonary venous connection.
A 21-month-old boy presented with persistent wheezing 16.5 months after cardiac surgery for supracardiac total anomalous pulmonary venous connection. 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 investigations including transthoracic and transesophageal echocardiograms revealed stenosis of the right pulmonary veins. Visualization and documentation of right pulmonary vein obstruction by pulmonary arterial wedge angiography and pressure tracings are presented.
