Modified closed chamber sutureless technique for anomalous pulmonary venous connection.

Visibility continues to be a major problem during repair of obstructed total anomalous pulmonary venous connection (TAPVC) resulting in frequent use of deep hypothermia and low flow bypass. Sutureless technique for primary repair of anomalous pulmonary venous connection is fast becoming popular. In this described modification of sutureless technique through the lateral approach, the left atrium is marsupialized around the common pulmonary venous chamber, except on the right lateral aspect, providing a bloodless field with minimal retraction of heart facilitating the surgery at mild hypothermia. This technique can be particularly useful in small confluence obstructed TAPVC and in mixed TAPVC.
