Atypical Case of Partial Anomalous Pulmonary Venous Connection Misdiagnosed as Primary Pulmonary Arterial Hypertension.

Atypical Case of Partial Anomalous Pulmonary Venous Connection Misdiagnosed as Primary Pulmonary Arterial Hypertension. Heart Surg Forum. 2017 Oct 31;20(5):E231-E233 Authors: Lu S, Wei L, Wang C Abstract In this case report, we present the delayed diagnosis of an atypical partial anomalous pulmonary venous connection, which was initially misdiagnosed as primary pulmonary arterial hypertension. It was difficult to make a conclusive diagnosis using transthoracic echocardiography (TTE), because the two high right superior pulmonary veins drained into the superior vena cava and limited the shunt of patent foramen ovale. Preoperative TTE only showed right heart volume overload, pulmonary arterial hypertension, and severe tricuspid valve insufficiency. A chest CT-angiography (angio-CT) finally found the anomalous right superior pulmonary venous connection, which was further confirmed by surgery. The postoperative course was uneventful.
