Background: Surgical valve repair is a good alternative for correction of incompetent bicuspid aortic valve. Aim: To report the early and late surgical, clinical and ecochardiographic results of surgical repair of incompetent bicuspid aortic valves. Patients and methods: Retrospective review of medical records of 18 patients aged 19 to 61 years, with incompetent bicuspid aortic valve in whom a valve repair was performed. Four patients had infectious endocarditis and 17 were in functional class I or II. Follow up ranged from 3 to 113 months after surgery. Results: A triangular resection of the prolapsing larger cusp, which included the middle raphe, was performed in 17 cases; in 13 of these, a complementary subcommisural annuloplasty was performed. In the remaining case, with a perforation of the non-coronary cusp, a pericardial patch was implanted; this procedure was also performed in 2 other cases. In 3 cases large vegetations were removed. Postoperative transesophageal echocardiography showed no regurgitation in 11 patients (62%) and mild regurgitation in 7 (38%). There was no operative morbidity or mortality. There were no deaths during the follow-up period. In 3 patients (17%) the aortic valve was replaced with a mechanical prosthesis, 8 to 108 months after the first operation. Reoperation was not needed in 93%±6,4% at 1 year and 85%±9,5% at 5 years, these patients were all in functional class I at the end of the follow-up period. 60% had no aortic regurgitation, 20% had mild and 20% moderate aortic regurgitation on echocardiographic examination. A significant reduction of the diastolic diameter of the left ventricle was observed, but there were no significant changes in systolic diameter or shortening fraction. Conclusions: Surgical repair of incompetent bicuspid aortic valves has low operative morbidity and mortality and has a low risk of reoperation (Rev Méd Chile 2005; 133: 279-86). (
CT angiography as the diagnostic and decision making method used for surgical indication in pulmonary hypertension due to chronic thromboembolism. Report of one casePulmonary hypertension due to chronic pulmonary thromboembolism is frequently underdiagnosed and has a very poor prognosis if untreated. When the presence of central pulmonary artery thrombus is confirmed, thromboendarterectomy is the treatment of choice, with very good results. We report a 28 years old male with two previous episodes of deep venous thrombosis (DVT) who was admitted due to 8 months of progressive shortness of breath and a syncope. He underwent a CT pulmonary angiogram and an echocardiogram. Severe pulmonary hypertension was confirmed, secondary to a chronic pulmonary thromboembolism with an overlapped acute component. He received systemic thrombolysis with partial thrombus disappearance. Therefore a pulmonary thromboendarterectomy was performed and an inferior vena cava filter was placed. The patient was discharged with marked improvement in his functional capacity (Rev Méd Chile 2005; 133: 565-9). (Recibido el 24 de mayo, 2004. Aceptado en versión corregida el 8 de marzo, 2005.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
