Abstract

This study was performed to analyse the impacts of functional mitral stenosis (MS) following mitral valve (MV) repair on late cardiac function and new onset of atrial fibrillation or survival. We retrospectively reviewed 602 patients with mitral regurgitation who underwent MV repair for Type II dysfunction from 2001. Functional MS was diagnosed when the mean transmitral pressure gradient (MTPG) was ≥5 mmHg on postoperative echocardiography. We analysed preoperative and surgical risk factors for functional MS (MS group). We then compared long-term outcomes and late cardiac function over time between patients in the MS and no-MS groups using a mixed-effects model with repeated measures. On postoperative echocardiography, 51 patients had an MTPG of ≥5 mmHg (MS group) and 551 had an MTPG of <5 mmHg (no-MS group). Only the ring size was an independent predictor of MS (28.8 ± 2.1 mm in the no-MS group vs 28.0 ± 1.9 mm in the MS group, P = 0.004). During follow-up, increases in the tricuspid regurgitation (TR) pressure gradient (PRV-RA) and TR severity over time were significantly greater in the MS group than in the no-MS group (PRV-RA: 0.72 ± 0.16 vs 0.35 ± 0.17 mmHg per year, respectively, P = 0.03; TR severity: 0.072 ± 0.014 vs 0.0...Continue Reading

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.

Atrial Fibrillation

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.
