Abstract

To summarize the early and midterm outcomes of artificial chordae transplant in mitral valve repair. A total of 50 patients underwent mitral valve repair with artificial chordae transplant from January 2009 to January 2010 in General Hospital of Shenyang Military Command. Follow-up was conducted on 48 cases (96%) for 3-4 years. No early postoperative mortality occurred. All cases had cardiac function New York Heart Association (NYHA) grade I/II at discharge. Among 48 cases, one died of cerebral infarction after 13 months and the reminder survived and no one underwent reoperation. Among survivors, 45 cases were in cardiac function NYHA grade I and another 2 in grade II. Echocardiography showed that postoperative 3 years left atrial diameter, left ventricular end-diastolic dimension, left ventricular end-systolic dimension and the ratio of regurgitation beam area and left atrial area were significantly smaller than those preoperative ones (39.5% ± 9.7% vs 5.6% ± 0.1%, P < 0.01) and left ventricular ejection fraction increased markedly (0.55 ± 0.06 vs 0.67 ± 0.07, P < 0.01). There was no instance of artificial chordae rupture. Gore-Tex artificial chordae transplant is a safe and effective technique in mitral valve repair with exce...Continue Reading

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
