A new type of coronary artery stent.

the right lung becomes functionally impaired as a result of lung disease or surgery. For instance, a right pneumonectomy could have fatal consequences in a patient with partial anomalous pulmonary venous drainage of the left upper lobe. In such a situation, shunt volume would dramatically increase to 50% of total pulmonary blood flow, and only the left lower lobe would be contributing to the systemic oxygen supply. In such situations, surgical correction of the anomalous drainage would be indicated. We report the rare situation of an anomalous pulmonary venous drainage, associated with a left-to-right shunt which became clinically relevant under specific conditions.
