Abstract

There are two commercially available transcatheter heart valve systems: balloon expandable valves (BEV) and self-expanding valves (SEV). However, there is a paucity of randomized trials comparing both systems. Electronic databases (Medline, the Cochrane Library, Web of Science, and clinicaltrials.gov) and major conference proceedings were searched for randomized trials of patients with symptomatic severe aortic stenosis and received transcatheter aortic valve implantation (TAVI) with a SEV or BEV or surgical aortic valve replacement. The main efficacy outcomes were all-cause mortality and stroke at the longest available follow-up. The main analysis was performed using a random-effects network meta-analysis complemented by several subgroup and sensitivity analyses. Ten trials with 9,439 patients (mostly undergoing transfemoral TAVI) were included. At a median of 27 months, there was no difference between BEV and SEV valves in terms of all-cause mortality (odds ratio [OR] 1.05, 95% confidence interval [CI] 0.79 to 1.42). The incidence of any stroke was higher with BEV (OR 1.51, 95% CI 1.01 to 2.26), but there was no difference in the incidence of disabling stroke. At 30-days, BEV valves were associated with lower incidence of new...Continue Reading

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.

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.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
