Meta AnalysisCulprit Vessel Only Versus Multivessel Percutaneous Coronary Intervention in Acute Myocardial Infarction with Cardiogenic Shock: A Systematic Review and Meta-Analysis.
Previous studies comparing outcomes between culprit vessel only percutaneous coronary intervention (CV-PCI) versus multivessel percutaneous coronary intervention (MV-PCI) in patients with cardiogenic shock in the setting of acute myocardial infarction have shown conflicting results. This meta-analysis investigates the optimal approach for management of these patients considering recently published data. ⋯ This meta-analysis showed lower short-term mortality and decreased odds of renal failure requiring renal replacement therapy with CV-PCI compared to MV-PCI. However, subgroup analysis including studies exclusively assessing STEMI patients revealed no statistically significant difference in outcomes. Further randomized trials are needed to confirm these findings and evaluate long term results.

Meta AnalysisTranscatheter versus surgical aortic valve replacement in low-risk surgical patients: A meta-analysis of randomized clinical trials.
Transcatheter aortic valve replacement (TAVR) is a valid option for patients with high or intermediate surgical risk. However, clinical outcomes of TAVR in low-risk patients are lacking. Our aim was to evaluate the efficacy and safety of TAVR versus surgical aortic valve replacement (SAVR) in low-surgical-risk patients. ⋯ Among low-risk patients, TAVR offered comparable efficacy outcomes and fewer bleeding events compared with SAVR. There were increased risks of pacemaker implantation and PVL associated with TAVR, though lower atrial fibrillation risks.

Meta AnalysisDrug-Eluting Versus Bare-Metal Stents in Older Patients: A Meta-Analysis of Randomized Controlled Trials.
Despite the high prevalence of ischemic heart disease in older patients, there is a substantial lack of evidence to guide clinical decision-making in this population. Hence, we performed a meta-analysis to determine the safety and efficacy of percutaneous coronary intervention (PCI) with drug-eluting stents (DES) versus bare-metal stents (BMS). ⋯ This meta-analysis of randomized clinical trials demonstrated that drug-eluting stents were associated with a significant reduction in major adverse cardiovascular events with no increased risk of bleeding compared with bare-metal stents. The risk of bleeding was high with longer dual antiplatelet therapy duration for patients who underwent DES placement. However, short duration of dual antiplatelet therapy substantially reduced major adverse cardiovascular events with no increased bleeding risk.

Meta AnalysisPercutaneous Closure of Patent Foramen Ovale in Patients with Cryptogenic Stroke - An Updated Comprehensive Meta-Analysis.
The ideal treatment strategy for patients with cryptogenic stroke and patent foramen ovale (PFO) is not yet clear. Previous randomized controlled trials (RCTs) comparing transcatheter PFO closure with medical therapy in patients with cryptogenic stroke to prevent recurrent ischemic stroke showed mixed results. This meta-analysis aims to compare rates of recurrent stroke, transient ischemic attack (TIA) and all-cause mortality with PFO closure and medical therapy vs. medical therapy alone. ⋯ The results of this meta-analysis suggest that transcatheter closure of PFO plus medical therapy is superior to medical therapy alone for the prevention of recurrent cryptogenic stroke. However, PFO closure in these patients has not been shown to reduce the risk of recurrent TIA or all-cause mortality. There is a higher rate of transient atrial fibrillation post PFO closure device placement, the long-term effects of which have yet to be studied.
