Methods: All patients treated with ULM-PCI with ultrathin stents (struts ≤81 μm) enrolled in the RAIN-CARDIOGROUP VII study were analyzed according to a sex-assessment evaluation. Major adverse cardiovascular event (MACE, a composite of all-cause death, myocardial infarction, target-lesion revascularization [TLR], and stent thrombosis) was the primary endpoint, whereas single components of MACE were the secondary endpoints.

Incidence, predictors and outcomes of valve-in-valve TAVI: A systematic review and meta-analysis.

Aims: Surgical aortic valve replacement has been the treatment of choice for patients with aortic valve disease before the arrival of transcatheter aortic valve replacement (TAVI), although limited by degeneration of the bioprosthesis. "Redo" intervention itself is burdened by high risk of complications and valve-in-valve (ViV) TAVI could be a valid strategy of redo for patients with comorbidities.

Methods And Results: Two independent reviewers screened all studies investigating patients undergoing ViV TAVI.

Comparison of bioresorbable vs durable polymer drug-eluting stents in unprotected left main (from the RAIN-CARDIOGROUP VII Study).

Meta-Analysis Comparing Complete or Culprit Only Revascularization in Patients With Multivessel Disease Presenting With Cardiogenic Shock.

The optimal strategy for patients with an acute myocardial infarction (MI) and multivessel (MV) coronary artery disease complicated by cardiogenic shock (CS) remains unknown. We conducted a meta-analysis of all randomized controlled trials and observational studies that reported adjusted effect measures to evaluate the association of MV-PCI (percutaneous coronary intervention), compared with culprit only (C)-PCI, with cardiovascular events in patients admitted for CS and MV disease. We identified 12 studies (n = 1 randomized controlled trials, n = 11 observational) that included 7,417 patients (n = 1,809 treated with MV-PCI and n = 5,608 with C-PCI).

Network meta-analysis comparing iFR versus FFR versus coronary angiography to drive coronary revascularization.

Aims: Instantaneous free-wave ratio (iFR) has been recently demonstrated non-inferior to fractional flow reserve (FFR) to drive coronary revascularization; however, no study has compared iFR versus coronary angiography (CA). We performed a network meta-analysis to evaluate efficacy and safety of iFR- versus CA-guided strategy.

Methods And Results: We searched for randomized trials and studies with propensity score matching in The Cochrane Collaboration Central Register of Controlled Trials, EMBASE, and MEDLINE/Pubmed.
