Hemodynamic response of the aortic valve during dobutamine onset then progressive aortic banding.

An increasing number of procedures over the past two decades for aortic stenosis (AS) reflects the combination of an aging population and less invasive transcatheter options. As a result, the hemodynamics of the aortic valve (AV) have gained renewed interest to understand its behavior and to optimize patient selection. We studied the hemodynamic relationship between pressure loss (ΔP) and transvalvular flow (Q) of the normal AV as well as the impact of a variable supravalvular stenosis.

Contemporary Use of Post-Dilatation for Stent Optimization During Percutaneous Coronary Intervention; Results From the Netherlands Heart Registration.

Backgrounds: Post-dilatation after stenting with a non-compliant (NC) balloon can be used to improve overall percutaneous coronary intervention (PCI) result. Due to lack of evidence on the effect of post-dilatation on adverse clinical endpoints there is no consensus whether post-dilatation should be used routinely. The aim of the current study was to determine the contemporary practice of post-dilatation.

Impact of Sheath Type on Vascular and Bleeding Complications After Transcatheter Aortic Valve Replacement: A Post Hoc Analysis From the MARVEL Registry Study.

Background: Vascular and bleeding complications remain a concern after transfemoral transcatheter aortic valve replacement (TAVR). The impact of the sheath type on these complications remains unclear.

Methods: The prospective MARVEL registry study analyzed enrolled 500 patients undergoing large-bore transfemoral procedures and arteriotomy closure with the MANTA vascular closure device from 10 hospitals in Europe and Canada.

Impact of Bifurcation Lesions on Outcomes After FFR-Guided PCI or CABG.

Background: In the era of first-generation drug-eluting stents and angiography-guided percutaneous coronary intervention (PCI), the presence of a bifurcation lesion was associated with adverse outcomes after PCI. In contrast, the presence of a bifurcation lesion had no impact on outcomes following coronary artery bypass grafting (CABG). Therefore, the presence of a coronary bifurcation lesion requires special attention when choosing between CABG and PCI.

Deferral of routine percutaneous coronary intervention in patients undergoing transcatheter aortic valve implantation: Rationale and design of the PRO-TAVI trial.

Background: Concomitant coronary artery disease (CAD) is highly prevalent in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI). The optimal treatment strategy for CAD is a topic of debate. An initial conservative strategy for CAD in patients undergoing TAVI may be favorable as multiple studies have failed to show an evident beneficial effect of percutaneous coronary intervention (PCI) on mortality after TAVI.
