Observational StudyThree Generations of Self-Expanding Transcatheter Aortic Valves: A Report From the STS/ACC TVT Registry.
The aim of this study was to assess the evolution of early outcomes for 3 iterative self-expanding transcatheter aortic valves. ⋯ Advancements in transcatheter valve technologies and expanding indications for TAVR have resulted in improved outcomes for patients undergoing TAVR in the United States with self-expanding, supra-annular valves. In particular, the addition of an outer pericardial tissue wrap designed to enhance sealing at the level of the aortic annulus has resulted in very low rates of significant aortic regurgitation while maintaining excellent hemodynamic status.

Safety of Paclitaxel-Coated Balloon Angioplasty for Femoropopliteal Peripheral Artery Disease.
The aim of this study was to assess safety outcomes of femoropopliteal drug-coated balloon (DCB) angioplasty using patient-level data from the Lutonix clinical program. ⋯ Analyses of patient-level data identified no mortality differences between DCB angioplasty and PTA. Furthermore, the lack of dose-response relationships or clustering of causes of death argues against a causal relationship between paclitaxel and mortality. (LEVANT 1, The Lutonix Paclitaxel-Coated Balloon for the Prevention of Femoropopliteal Restenosis [LEVANT 1], NCT00930813; Moxy Drug Coated Balloon vs. Standard Balloon Angioplasty for the Treatment of Femoropopliteal Arteries [LEVANT 2], NCT01412541; LEVANT 2 Continued Access Registry, NCT01628159; LEVANT Japan Clinical Trial, NCT01816412).

Randomized Controlled Trial Multicenter Study Comparative Study1-Year Outcomes of Delayed Versus Immediate Intervention in Patients With Transient ST-Segment Elevation Myocardial Infarction.
The aim of the present study was to determine the effect of a delayed versus an immediate invasive approach on final infarct size and clinical outcome up to 1 year. ⋯ At follow-up, patients with transient STEMI have limited infarction and well-preserved myocardial function in general, and delayed or immediate revascularization has no effect on functional outcome and clinical events up to 1 year.

Multicenter StudyClinical Implication of Quantitative Flow Ratio After Percutaneous Coronary Intervention for 3-Vessel Disease.
The aim of this study was to investigate the impact of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) on clinical outcomes in patients with de novo 3-vessel disease (3VD) treated with contemporary PCI. ⋯ A higher post-PCI QFR value is associated with improved vessel-related clinical outcomes in state-of-the art PCI practice for de novo 3VD. Achieving a post-PCI QFR value ≥0.91 in all treated vessels should be a target when treating de novo 3VD. These findings require confirmation in future prospective trials.
