Key result
Surgical closure of the atrial septal defect combined with tricuspid annuloplasty and coronary artery bypass grafting resulted in clinical stability and no further episodes of angina at 6 months.

Highlights a rare case of extrinsic LMCA compression by an enlarged pulmonary artery due to ASD and pulmonary hypertension, successfully treated with combined structural and bypass surgery.
Consider extrinsic LMCA compression by dilated PA in ASD-PAH; single case leaves open need for systematic evaluation.
We report the case of an adult referred to our center with an initial diagnosis of stenosis of the left main coronary artery (LMCA). A preoperative investigation disclosed an atrial septal defect (ASD) with pulmonary artery hypertension. The angiographic studies confirmed the diagnosis and showed external compression of the LMCA by an enlarged pulmonary artery. Surgical closure of the ASD and tricuspid valve ring annuloplasty with coronary artery bypass surgery (left internal mammary artery to left anterior descending artery) were undertaken. Six months after the surgery, the patient is doing well.

Ergenoglu et al. (2012) conducted a case report in Extrinsic compression of the left main coronary artery (n=1). Surgical closure of ASD, tricuspid valve ring annuloplasty, and CABG (LIMA to LAD) was evaluated on Clinical stability and angina episodes. Surgical closure of the atrial septal defect combined with tricuspid annuloplasty and coronary artery bypass grafting resulted in clinical stability and no further episodes of angina at 6 months.
