Gazapos de la insuficiencia mitral: ¿una simuladora de estenosis aórtica?

Rev. méd. Maule; 39 (3), 2024
The article discusses mitral regurgitation (MI), a heart condition characterized by incomplete closure of the mitral valve, which causes regurgitation of blood into the left atrium. This problem can be due to various etiologies, such as degenerative or ischemic diseases, and is mainly evaluated with Dopp...

Medição automática de valva mitral a partir de ecocardiograma utilizando processamento digital de imagens

ABC., imagem cardiovasc; 36 (1), 2023
Fundamento: A avaliação da área valvar mitral por meio da reconstrução multiplano na ecocardiografia tridimensional é restrita a softwares específicos e à experiência dos ecocardiografistas. Eles precisam selecionar manualmente o frame do vídeo que contenha a área de abertura máxima da valva ...

Miocardiopatía de y movimiento sistólico anterior de válvula mitral

Rev. chil. anest; 49 (4), 2020
Tako tsubo cardiomyopathy associated with left ventricular outflow tract obstruction (LVOT) is a rare cause of persistent perioperative hypotension. One of the causes of this association is the systolic anterior motion (SAM) of the mitral valve. We report a case of a 67-year-old woman who, after undergoi...

The relationship between mitral annular calcification, metabolic syndrome and thromboembolic risk

Abstract Introduction: Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery diseas...

The factors affecting rhythm control for cryoablation of atrial fibrillation in mitral valve surgery

Abstract Objective: To evaluate the factors impacting on the conversion to sinus rhythm and on the postoperative rhythm findings in the six-month follow-up period of a mitral valve surgery combined with cryoablation Cox-Maze III procedure, in patients with atrial fibrillation. Methods: In this study, w...

Surgical treatment of atrial fibrillation in patients with rheumatic valve disease

Abstract Objective: To assess heart rhythm and predictive factors associated with sinus rhythm after one year in patients with rheumatic valve disease undergoing concomitant surgical treatment of atrial fibrillation. Operative mortality, survival and occurrence of stroke after one year were also evaluat...

Progressão de Valvopatia Esquerda durante o Uso de Dopaminérgicos

ABC., imagem cardiovasc; 30 (2), 2017
A cabergolina e a bromocriptina são drogas dopaminérgicas derivadas do ergot e utilizadas para tratamento de distúrbios hiperprolactinêmicos idiopáticos ou adenomas hipofisários, cujo mecanismo de ação é decorrente da redução da secreção de prolactina. Alguns relatos na literatura demonstram...

Experimental validation of a cardiac simulator for in vitro evaluation of prosthetic heart valves

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,...
