Resultados imediatos da artéria torácica interna direita e artéria radial como segundo enxerto arterial em revascularização do miocárdioImmediate results of right internal thoracic artery and radial artery as the second arterial graft in myocardial revascularization Abstract Objective: We sought to compare early clinical outcomes in patients receiving a right internal thoracic artery or a radial artery as the second arterial graft in myocardial revascularization.Methods: We retrospectively studied 58 consecutive patients who underwent coronary artery bypass surgery and received both a left internal thoracic artery graft and either a right internal thoracic artery (n=20) or a radial artery graft (n=38), between January 2004 and March 2006. Hospital mortality, pleural drainage, operative time and postoperative complications were analyzed.Results: There were no significant preoperative differences between groups. There was only one (1.7%) in-hospital death which occurred in the Radial Group. Operative times was significantly higher in the Right Internal Thoracic Group (p-value = 0.0018), but were not associated with increased Intensive Care Unit stays, mechanical ventilation or other postoperative complications. We were able to perform significantly more distal anastomosis using the radial artery than the right internal thoracic artery (1.57 versus 1.05: pvalue =0.003).Conclusion: In our group of patients, the use of a right internal thoracic artery as a second arterial graft was associated with a prolonged operative time, but had no interference with the immediate clinical outcomes. 61MIANA, LA ET AL -Immediate results of right internal thoracic artery and radial artery as the second arterial graft in myocardial revascularization Braz J Cardiovasc Surg 2007; 22(1): 60-67

Objetivo: Avaliar a experiência cirúrgica do grupo no tratamento dos tumores cardíacos durante o período de janeiro de 1985 a dezembro de 1994. Casuística e Métodos: De um total de 2268 cirurgias cardíacas com circulação extracorpórea realizadas neste período de 10 anos, 6 foram para extirpação de tumores intracavitários, perfazendo 0,26% dos casos. Destes, 3 eram mixomas de átrio esquerdo, 1 fibroelastoma papilar de valva mitral, 1 rabdomioma de ventrículo esquerdo e 1 fibroma de ventrículo esquerdo. A forma clínica de apresentação foi embolia sistêmica (3 casos) ou insuficiência cardíaca (3 casos). O diagnóstico foi ecocardiográfico (5 casos) e angiográfico (6 casos). Resultados: Todos os pacientes tiveram evolução imediata favorável, exceto 1 deles, com mixoma de átrio equerdo, que evoluiu com mediastinite e septicemia, vindo a falecer e constituindo o único óbito hospitalar. O seguimento pós-operatório tardio, obtido em 4 pacientes (15 a 111 meses - média 49 ± 36,8 meses), não detectou qualquer recidiva, encontrando-se todos em classe funcional I (NYHA). Conclusões: Os autores concluem que os tumores cardíacos são bastante raros, de fácil diagnóstico desde que considerados, na grande maioria benignos e que cursam favoravelmente com a extirpação cirúrgica.
Purpose: To review the surgical experience of our group in the treatment of primary cardiac tumors, during a 10 year period beginning January 1985 till December 1994. Material and Methods: From a total of 2268 cardiac surgeries with the aid of extracorporeal circulation performed during this 10 year period, there were 6 cases of intracavitary tumor resection, an incidence of 0.26%. Three were myxomas of the left atrium, 1 papillary fibroelastoma of the mitral valve, 1 rhabdomyoma of the left ventricule and 1 fibroma of the left ventricle. Three patients presented systemic embolism and the other three congestive heart failure. The diagnosis was confirmed by echocardiography (5 cases) and angiography (all 6 cases). Results: All patients had uneventful revovery, except 1, with atrial myxoma, who developed mediastinitis and sepsys, dying on the 14th. post-operative day and becoming the unique hospital death. The follow up obtained in 4 patients with mean duration of 49 ± 36.8 months (range, 15 to 111 months) showed that all of them were in functional class I (NYHA) and with no evidence of recurrence. Conclusions: Cardiac tumors are rare, easily diagnosed "as long as you think of them" (Soma Weiss), most of them bening and have a favorable outcome with surgical resection

Objective: Retrospective study evaluating the morbidmortality and hospital behavior in over 70-year-old patients submitted to myocardial revascularization involving the radial artery as the second arterial graft. Method: During the period of August 1994 to December 2002, 2487 cases of myocardial revascularization were performed by the group of the Juiz de Fora Heart Institute, 476 of whom were 70 years of age or older and 36 (Group II) received the radial artery as the second arterial graft. The same type of surgery was performed in 142 under 70-year-old patients (Group I). Reoperations, off-pump operations (OPCAB) or associated procedures were excluded from this study. Results: The median age was 72.5 years, the mortality rate was 6% in this group of patients and the incidence of complications was low, comparable to the 142 under 70-yearold patients (Group I) submitted to the same type of surgery. Conclusion: The results achieved with this study lead the authors to believe that the radial artery can be safely used as the second arterial graft in well selected septuagenarian patients, despite the greater risk of co-morbidities related to this age group.
