[The Long-term Results of Valve Sparing Aortic Root Replacement and Aortic Cusp Repair for Aortic Regurgitation].

We reported our long-term results of valve sparing aortic root replacement (VSRR) and aortic cusp repair for aortic regurgitation( AR) were satisfactory. Three hundred twenty-seven patients had VSRR, and 164 patients of them had aortic cusp repair for prolapse. At 10 years after the operation, the overall survival was 91.5%, the freedom from more than mild recurrent AR was 71.2%, and the freedom from aortic valve reoperation was 82.0%. As for the aortic cusp repair technique, there was no significant difference in the mid-term results of the recurrent AR and reoperation for the aortic valve between the central plication technique and the resuspension technique (two layers of continuous mattress sutures placed the entire length of the free margin of the aortic cusp). The resuspension technique might be useful for repairing the aortic cusp with prolapse. Furthermore, among the patients with acute aortic dissection, connective tissue disease, or aortitis, the long-term results of VSRR and aortic cusp repair were also satisfactory.

[Repair of Traumatic Brachiocephalic Artery Pseudoaneurysm by Open Surgery:Report of a Case].

The patient is a 56-year-old man. He fell while playing golf and sustained a contusion on his right chest. He fell into hemorrhagic shock during surgery for a right clavicle fracture at a nearby hospital and required cardiac resuscitation. Computed tomography( CT) scan revealed left pneumothorax and right hemothorax, and a contrast-enhanced CT scan revealed a pseudoaneurysm at the brachiocephalic artery origin. He underwent surgery three weeks later. Surgery was performed through a median sternotomy and partial arch replacement (zone 2) with antegrade cerebral perfusion under moderate hypothermia. He was discharged on postoperative day 10 without significant complications.

Long-term Results of Valve-Sparing Aortic Root Replacement and Aortic Cusp Repair.

BACKGROUND: Long-term results of valve-sparing aortic root replacement (VSRR) and aortic cusp repair for aortic regurgitation are unclear. METHODS: VSRR by reimplantation was performed in 363 patients. Tricuspid aortic valve (TAV) and bicuspid aortic valve were found in 285 and 71 patients, respectively. RESULTS: Aortic cusp repair was performed in 268 patients. Of patients with TAV 129 had central plication of the Arantius node, 36 had free margin resuspension, and 71 had reinforcement. Mean follow-up was 71.4 months. Among TAV patients freedom from aortic valve reoperation at 10 and 15 years was 85.1% and 78.3%, respectively. Freedom from aortic valve reoperation at 10 years was lower in patients with cusp prolapse than without (77.4% vs 93.2%, P = .007). The overall freedom from more than mild aortic regurgitation at 10 and 15 years was 72.4% and 64.0%, respectively. It was also significantly greater in patients without cusp prolapse (78.4% vs 67.7%, P = .02). As for the cusp repair technique the freedom from aortic valve reoperation at 10 years was significantly better in patients who underwent only resuspension or reinforcement techniques compared with patients who underwent only central plication technique (100% vs 72.8%, P = .008). CONCLUSIONS: Long-term results of VSRR with aortic cusp repair were satisfactory. The resuspension technique appears to be useful for repairing aortic cusp prolapse in patients with TAV.
