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.
