    CT angiography as the diagnostic and decision making method used for surgical indication in pulmonary hypertension due to chronic thromboembolism. Report of one case
    (SOC MEDICA SANTIAGO, 2005) Claro, JC; Baudrand, R; Baeza, C; Letelier, LM
    Pulmonary hypertension due to chronic pulmonary thromboembolisin 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 thromboembolisin 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.

    (SOC MEDICA SANTIAGO, 2005) Zalaquett, R; Campla, C; Scheu, M; Cordova, S; Becker, P; Moran, S; Irarrazaval, MJ; Baeza, C; Arretz, C; Braun, S; Chamorro, G; Godoy, I; Yanez, F
    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 infections endocarditis and 17 were in functional class I or II. Follow up ranged from 3 10 113 months after surgery. Results: A triangular resection of the prolapsing larger cusp, which included the middle raphe, was performed in 17 cases, in 73 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 wets not needed in 93% 6,4% at 1 year and 85% 9,5% at 5 years, these patients were all in functional class 1 (it the end of the follow-lip period. 60% bad 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.
