Zilebesiran and Hypertension: A Systematic Review and Meta-analysis.

Objectives: Zilebesiran is an investigational RNA interference therapeutic designed to lower blood pressure by targeting the hepatic production of angiotensinogen, the most upstream precursor of the renin-angiotensin-aldosterone system. This approach aims to offer long-lasting blood pressure control with potentially fewer doses compared to traditional antihypertensive medications. The objective of this systematic review and meta-analysis was to assess the antihypertensive efficacy of zilebesiran in patients with hypertension.

Comparative Efficacy and Safety of Transcatheter Mitral Valve Repair Versus Mitral-valve Surgery in Elderly Patients With Mitral Regurgitation: A Systematic Review and Meta-analysis.

Objectives: Mitral valve surgery is the reference treatment for severe symptomatic mitral regurgitation (MR). Percutaneous mitral valve interventions, such as the MitraClip procedure, offer an alternative, particularly for high-risk patients. The aim of this systematic review and meta-analysis was to analyze the safety and effectiveness of transcatheter mitral valve repair (TMVR) compared to surgical mitral valve repair or replacement (SMVR) in elderly patients with mitral regurgitation.

Comparative Outcomes of Transcatheter Versus Surgical Aortic Valve Replacement in Elderly Patients With Severe Symptomatic Aortic Stenosis: A Systematic Review.

Objectives: Aortic stenosis is the most common valvular heart disease globally; while transcatheter aortic valve replacement (TAVR) has proven to be a competitive alternative to surgical aortic valve replacement (SAVR) and revolutionized treatment, its safety and efficacy has yet to be comprehensively assessed against SAVR for certain subsets of aortic stenosis patients; therefore, this study aims to systematically analyze all the available clinical evidence from randomized clinical trials on TAVR versus SAVR among intermediate and low-risk patients with severe symptomatic aortic stenosis.

Methodology: We performed a systematic review of the randomized controlled trials (RCT), studies comparing TAVR and SAVR in low- and intermediate-risk patients were identified by a comprehensive search of the major databases. Mortality, stroke, length of stay, and other perioperative outcomes were assessed.
