Review Meta Analysis Comparative Study
Transcatheter aortic valve replacement versus surgical aortic valve replacement in patients with previous coronary artery bypass surgery: A systematic review and meta-analysis.
Patients with severe aortic stenosis (AS) and previous coronary artery bypass graft (CABG) surgery have increased risk for aortic valve replacement. Whether surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) offers better outcomes in this population is unclear. We aimed to assess outcomes of TAVR and SAVR in patients with previous CABG. ⋯ Patients with previous CABG who underwent TAVR had similar perioperative and long-term survival while experiencing more pacemaker implantations and shorter hospital stay compared to those who had SAVR making TAVR a safe and efficacious alternative to SAVR.

Levosimendan meta-analyses: Is there a pattern in the effect on mortality?
Levosimendan is an inodilator developed for treatment of acute heart failure and other cardiac conditions where the use of an inodilator is considered appropriate. Levosimendan has been studied in different therapeutic settings including acutely decompensated chronic heart failure, advanced heart failure, right ventricular failure, cardiogenic shock, septic shock, and cardiac and non-cardiac surgery. This variety of data has been re-analysed in 25 meta-analyses from 15 different international research groups, based on different rationales to select the studies included. ⋯ The existing meta-analyses, now based on a population of over 6000 patients, provide the general message of significant benefits for levosimendan in terms of patient mortality. The weight of evidence is now clearly in favour of usefulness/efficacy of levosimendan, with data from multiple randomized trials and meta-analyses.

Review Meta Analysis
Efficacy and safety of preoperative intra-aortic balloon pump use in patients undergoing cardiac surgery: a systematic review and meta-analysis.
Intra-aortic balloon pump (IABP) can be used prior to coronary artery bypass graft surgery (CABG) in high-risk patients. Whether this technique remains safe and effective in contemporary practice is controversial. ⋯ In contemporary practice, evidence showing clinical benefit for preoperative IABP in high-risk patients remains limited and requires further validation in an appropriately sized multicenter randomized trial.

Relative efficacy and safety of non-Vitamin K oral anticoagulants for non-valvular atrial fibrillation: Network meta-analysis comparing apixaban, dabigatran, rivaroxaban and edoxaban in three patient subgroups.
Stroke is the most serious clinical consequence of atrial fibrillation, which is the most common cardiac arrhythmia. Non-vitamin K antagonist oral anticoagulants (NOACs) have emerged as efficacious, safe and convenient stroke prevention agents. This updated network meta-analysis focused on the relative efficacy and safety of apixaban compared with dabigatran, rivaroxaban and edoxaban for stroke prevention in (i) patients with CHADS2 score ≥ 2, (ii) secondary stroke prevention, and (iii) patients with high quality anticoagulation control with warfarin. ⋯ Among the NOACs, apixaban offered the most favourable efficacy and safety profile in the overall patient population as well as in the three subgroups investigated.
