Postangioplasty Aneurysm Of Right Coronary Artery

Background: Coronary artery aneurysms are an uncommon disease whose incidence ranges from 0.3% to 5.3%. The right coronary artery is affected in 40%-70% of cases. Percutaneous coronary angioplasty is among causative factors, in particular with stent implantation.Aims: We present a case of large postangioplasty aneurysm of the right coronary artery requiring surgical correction.Materials & Methods: A 70-year-old man with history of multiple coronary angioplasty procedures was admitted with diagnosis of aneurysm of the right coronary artery at the site of past DES insertion.Results: Under cardiopulmonary bypass, the large aneurysm was incised and oversewn with final grafting of the posterior descending artery with in situ right internal mammary artery. The postoperative course was uneventful.Discussion: The treatment options for coronary artery aneurysms range from medical, percutaneous and surgical approaches.Conclusion: In this case the surgical approach was indicated due to the large aneurysm and the high risk of rupture.
