Role of Intravascular Imaging in Complex Percutaneous Coronary Intervention: A Meta-Analysis of Randomized Controlled Trials.

Intravascular imaging (IVI) during percutaneous coronary intervention (PCI) has been shown to improve clinical outcomes. However, data is limited in complex PCI and the adoption remains low. We aimed to conduct a meta-analysis of all available randomized controlled trials comparing IVI with conventional angiography in patients who underwent complex PCI.

Effect of Furosemide Versus Torsemide on Hospitalizations and Mortality in Patients With Heart Failure: A Meta-Analysis of Randomized Controlled Trials.

Loop diuretics are essential in the treatment of patients with heart failure (HF) who develop congestion. Furosemide is the most commonly used diuretic; however, some randomized controlled trials (RCTs) have shown varying results associated with torsemide and furosemide in terms of hospitalizations and mortality. We performed an updated meta-analysis of currently available RCTs comparing furosemide and torsemide to see if there is any difference in clinical outcomes in patients treated with these loop diuretics.

Safety and Effectiveness of Adjunctive Posterior Wall Isolation in Atrial Fibrillation Patients: An Updated Meta-Analysis.

As the atrial fibrillation (AF) recurrence rate remains high after pulmonary vein isolation (PVI), additional left atrial posterior wall isolation (PWI) has been studied in randomized controlled trials, however, the results are conflicting. We performed an updated meta-analysis by searching online databases for the randomized controlled trials comparing the PWI + PVI group to the PVI alone group in patients with AF. The outcomes of interest were AF recurrence, all atrial arrhythmia recurrence, and atrial flutter/atrial tachycardia (AT) recurrence.
