Fissurating aneurysm of the right coronary artery repaired with interposition of a Gore-Tex graft

Abstract

Coronary artery aneurysms are exceedingly rare and are most often discovered incidentally. Rupture of such aneurysms is even more uncommon. In this case report, we describe an 82-year-old patient who presented with sudden-onset chest pain and was diagnosed with a fissurating aneurysm of the right coronary artery. The aneurysm was associated with a congenital abnormality of the coronary venous sinus return. The patient underwent emergency surgery. Given her advanced age, the surgical strategy focused solely on addressing the imminent risk of rupture. A 10-mm Gore-Tex graft was implanted because direct suture repair or vein grafting was deemed unsuitable. The patient recovered well postoperatively and was given dual antiplatelet therapy. At nine months of follow-up, she remains asymptomatic, with no recurrence of chest pain.
