RESUMEN
Objective: Postoperative atrial fibrillation is a common complication after cardiac surgery, with an incidence as high as 20-50%. Increased age is associated with a significant increase in postoperative atrial fibrillation risk. This common complication is associated with higher morbidity and mortality rates. The aim of this study was to assess the efficacy of nebivolol in preventing atrial fibrillation following coronary artery bypass surgery in patients over 60 years of age. Methods: In this prospective randomized study, 200 patients who were candidates for elective coronary artery bypass surgery were divided into two groups. The first group was administered with nebivolol and the second group was administered with metoprolol. Treatment was initiated four days prior to surgery, and patients were monitored for atrial fibrillation until discharge. Forty-one patients recieved 50 mg metoprolol succinate daily, which was initiated minimum 4 days before surgery. Results: Demographic data were similar in both groups. The incidence of postoperative atrial fibrillation in both groups was similar, with no significant difference being identified [n=20 (20%); n=18 (18%), P=0.718; respectively]. There were not any mortality at both groups during study. Inotropic agent requirement at ICU was similar for both groups [n=12 (12%), n=18 (18%), P=0.32]. Conclusion: We compared the effectiveness of nebivolol and metoprolol in decreasing the incidence of postoperative atrial fibrillation, and determined that nebivolol was as effective as metoprolol in preventing postoperative atrial fibrillation at patients. Nebivolol may be the drug of choice due to its effects, especially after elective coronary artery bypass surgery. .
Objetivo: Pós-operatório fibrilação atrial é uma complicação comum após a cirurgia cardíaca, com uma incidência tão elevada quanto 20-50%. O aumento da idade está associado com elevação significativa no risco de pós-operatório da fibrilação atrial. Esta complicação comum é associada com taxas de morbidade e mortalidade. O objetivo deste estudo foi avaliar a eficácia do nebivolol na prevenção da fibrilação atrial após cirurgia de revascularização do miocárdio de pacientes acima de 60 anos de idade. Métodos: Neste estudo prospectivo e randomizado, duzentos pacientes candidatos à cirurgia de revascularização do miocárdio foram divididos em dois grupos. O primeiro grupo foi administrado com nebivolol e o segundo grupo, com metoprolol. O tratamento foi iniciado quatro dias antes da cirurgia, e os pacientes foram monitorados para fibrilação atrial até a alta. Quarenta e um pacientes receberam 50 mg de sucinato de metoprolol diário, que foi iniciado, no mínimo, 4 dias antes da cirurgia. Resultados: Os dados demográficos foram semelhantes nos dois grupos. A incidência de fibrilação atrial pós-operatória em ambos os grupos foi semelhante, com nenhuma diferença significativa sendo identificado [n=20 (20%); n=18 (18%), P=0,718; respectivamente]. Não houve mortalidade em ambos os grupos durante o estudo. A necessidade de agente inotrópico em UTI foi semelhante nos dois grupos [n=12 pessoas (12%), n=18 (18%), P=0,32]. Conclusão: Nós comparamos a eficácia do nebivolol e metoprolol na diminuição da incidência de fibrilação atrial no pós-operatório, e verificamos que nebivolol foi tão eficaz como metoprolol na prevenção de fibrilação atrial no pós-operatório em pacientes. Nebivolol pode ser a droga de escolha devido aos seus efeitos, especialmente depois da cirurgia revascularização do miocárdio. .

We present a case of successful repair of the mitral valve for active infective endocarditis. Mitral valve repair was performed through debridement of vegetation and abscess, resection and repair of the posterior mitral leaflet and posterior repair with autologous pericardium. Postoperative period was uneventfully, with no evidence of recurrent infection, and echocardiogram showed mitral valve competence with mild mitral regurgitation. We demonstrate that valve repair is a feasible choice in cases of active endocarditis in children.

Apresentamos um caso de reparo bem-sucedido da valva mitral decorrente de endocardite infecciosa ativa. Reparo da valva mitral foi acompanhado de desbridamento da vegetação e do abscesso, ressecção e plastia do folheto mitral posterior, e anuloplastia posterior com pericárdio autólogo. Pós-operatório sem evidências de infecção recorrente, e ecocardiograma demonstrou competência da valva mitral com regurgitação mitral trivial. Concluímos que o reparo valvar é uma escolha viável em caso de endocardite ativa nas crianças.
