Aneurysmal transformation of a venous coronary bypass graft is a rare (incidence of 0.07%), yet potentially fatal complication of coronary artery bypass grafting. It is postulated > 5 years following coronary artery bypass graft (CABG) multiple factors contribute to the development of graft aneurysm, including atherosclerosis, endothelial dysfunction, changes in smooth muscle orientation in the proximity of valves [ ] and trauma during surgical handling of the vein [ ]. Establishing the final diagnosis is hampered by unspecific clinical presentation (chest pain, dyspnea), with nearly 1/3 of cases being diagnosed incidentally [ ]. In consequence, patients undergo extensive and time-consuming cardiological workup prior to treatment. Despite cardiac surgery remaining the mainstay of treatment for coronary bypass graft aneurysms, minimally invasive endovascular procedures constitute an accepted and effective alternative for patients with multiple comorbidities without mechanical complications [ – ].
