Valve-sparing partial root repair for aortic dissection limited to the right coronary sinus of Valsalva.

BACKGROUND AND AIM OF THE STUDY: To reveal a technical feasibility and safety of valve-sparing partial aortic root repair for spontaneous aortic dissection limited to the right coronary sinus of Valsalva.

METHODS

A 68-year-old woman presented with chest pain. Twelve-lead electrocardiogram revealed atrioventricular dissociation and ST-segment elevation on II, III, and aVF. Enhanced computed tomography images showed aortic dissection limited to the right-coronary sinus and the other non-dilated sinuses of Valsalva. Localized aortic dissection was repaired by valve-sparing partial aortic root repair using a trimmed U-shaped Dacron graft and a felt strip, and the right coronary artery was revascularized by coronary artery bypass grafting using saphenous vein graft.

RESULTS

The patient was discharged on postoperative day 12 with no complications.

CONCLUSION

Valve-sparing partial aortic root repair with the patch and coronary artery bypass grafting for aortic dissection limited to the right coronary sinus of Valsalva were technically feasible and safe.
