A Retrospective Analysis Assessing Paravalvular Leak and Pacemaker Implantation Using TEE and Non-Contrast CT for CKD Patients Compared With CT Angiography for Annular Sizing Pre-TAVR.

Background And Aims: Transcatheter aortic valve replacement (TAVR) has become the treatment of choice for many patients with severe aortic stenosis. Proper pre-procedure sizing of the aortic annulus is crucial in preventing post-TAVR complications. This is typically performed with CT angiography, but the use of contrast is controversial in patients with chronic kidney disease (CKD).

Sharp Recanalization with the Upstream GoBack Catheter for Chronic Occlusive Ilio-Caval Thrombosis.

Recanalization of chronic iliofemoral deep vein thrombosis is indicated to reduce symptoms and improve quality of life. However, recanalization is dependent on the ability to cross chronic obstructions. We present a case of chronically thrombosed inferior vena cava and common iliac veins that failed conventional crossing techniques but were successfully recanalized using the recently approved Upstream GoBack Crossing Catheter.
