Randomized Controlled Trial Multicenter Study Comparative StudyA multicenter randomized comparison of drug-eluting balloon plus bare-metal stent versus bare-metal stent versus drug-eluting stent in bifurcation lesions treated with a single-stenting technique: six-month angiographic and 12-month clinical results of the drug-eluting balloon in bifurcations trial.
Percutaneous treatment of coronary bifurcation lesions remains hampered by suboptimal results, mainly in the side branch (SB), even with the use of drug-eluting stents (DES). Paclitaxel drug-eluting balloons (DEB) could provide an attractive alternative to treat bifurcations in combination with a provisional T-stenting technique in order to minimize SB restenosis. We compared angiographic and clinical outcomes of a provisional T-stenting technique with a DEB plus bare-metal stent (BMS) versus BMS versus paclitaxel DES. ⋯ Pretreatment of both MB and SB with DEB failed to show angiographic and clinical superiority over conventional BMS, using a provisional T-stenting technique. Moreover DES showed superior angiographic results than DEB and BMS.

Percutaneous retrograde left ventricular assist support for interventions in patients with aortic stenosis and left ventricular dysfunction.
To evaluate feasibility and technical outcomes in patients with aortic stenosis (AS) who have undergone high-risk procedures with continuous flow left ventricular (LV) assist, with the Impella 2.5 system (Abiomed, Danvers, MA). ⋯ Our data suggests that continuous flow LV assist with Impella 2.5 can be used in high-risk patients with severe AS who require periprocedural hemodynamic support.

Contemporary use of adjunctive thrombectomy during primary percutaneous coronary intervention for ST-elevation myocardial infarction in the United States.
We sought to examine the contemporary use of thrombectomy during primary percutaneous coronary intervention (PCI) in the United States. ⋯ Our data show that thrombectomy is performed infrequently in the US during primary PCI for STEMI. There is significant variation in the use of thrombectomy across US hospitals.
