Predictors of high-degree atrioventricular block in patients with new-onset left bundle branch block following transcatheter aortic valve replacement.

Background: The development of new left bundle branch block (LBBB) is frequently seen post TAVR and is a known risk factor for progression to high degree AV block. The timing and likelihood of progression into complete heart block is variable and can develop after hospital discharge. We sought to determine predictors for the development of high degree AV block in patients who developed LBBB following TAVR.

Integrating hemodynamics with ventricular and valvular remodeling in aortic stenosis. A paradigm shift in therapeutic decision making.

Aortic valve stenosis (AS) has traditionally been approached in hemodynamic terms. Although hemodynamics and symptoms have formed the basis of recommending interventional treatment in AS, other factors reflecting left ventricular and valvular and/or vascular remodeling are equally important for the prognosis and outcome of patients with AS. Left ventricular and valvular/vascular remodeling in AS do not consistently correlate with hemodynamic severity of AS.

The Single-Access Technique for Impella Protected Percutaneous Coronary Intervention: A Single-Center Experience.

In this era of complex high-risk percutaneous coronary intervention (HR-PCI), mechanical support is being increasingly used. Traditionally, mechanical circulatory support with the Impella CP device requires a large-bore arterial access and an additional arterial access for the subsequent coronary intervention. We present a case series of the novel single-access for HR-PCI (SHIP) technique, in which a single arterial access is used for both mechanical support and coronary intervention.
