Abstract:
A young female patient was referred for pulmonary arterial hypertension (PAH). Catheterization revealed a large sinus venosus interatrial communication (SVIAC), partial anomalous pulmonary venous return (PAPVR), pulmonary vascular resistance (PVR) 15 Wood units, and bidirectional shunting. She was then put on target medication for PAH. Two years later, she had angina and underwent computed tomography examination, which showed pulmonary arterial aneurysm compressing the left main coronary. Coronary stenting was performed, which successfully relieved the compression and angina. Meanwhile, PVR lowered to 3.5 Wood units after medical therapy. Surgical correction for SVIAC and PAPVR was done successfully 5 years after diagnosis.
