Abstract Background and objectives: The aneurysm in the pulmonary trunk is a rare disease. Because of its location, a rupture can lead to right ventricular failure and sudden death. Aneurysmorraphy is the most widely used surgical treatment in these cases. The aim of this study is to report a successful...
Com o envelhecimento populacional, o implante percutâneo de bioprótese valvular aórtica (TAVI, sigla em inglês) vem ganhando espaço no tratamento da estenose aórtica em indivíduos de maior risco operatório. A seleção do paciente para intervenção, no atual momento, leva em consideração risco...
O implante de prótese valvar aórtica por cateter (TAVI, do inglês transcatheter aortic valve implantation) constitui o tratamento de escolha para pacientes com estenose aórtica considerada inoperável e surge como opção terapêutica à cirurgia em indivíduos com alto e moderado risco operatório. ...
Resumen Objetivo: Evaluar el EuroSCORE II y el STS score como predictores de la morbilidad y la mortalidad postoperatoria en pacientes que van a la cirugía cardiaca valvular aislada por el abordaje mínimamente invasivo. Metodología: Estudio observacional de una cohorte retrospectiva de 273 pacient...
Abstract Background: Paravalvular regurgitation (paravalvular leak) is a serious and rare complication associated with valve replacement surgery. Studies have shown a 3% to 6% incidence of paravalvular regurgitation with hemodynamic repercussion. Few studies have compared surgical and percutaneous appro...
Abstract Objective: To complement the ISO 5840 standards concerning the duration of left ventricular systole and diastole as a function of changes in heart rates according to in vivo studies from the physiologic literature review. Methods: The systolic and diastolic durations from three in vivo studies...
Abstract Objective: This work describes the experimental validation of a cardiac simulator for three heart rates (60, 80 and 100 beats per minute), under physiological conditions, as a suitable environment for prosthetic heart valves testing in the mitral or aortic position. Methods: In the experiment,...
