Contact-Free Optical Assessment of Changes in the Chest Wall Perfusion after Coronary Artery Bypass Grafting by Imaging Photoplethysmography [PDF]

Applied Sciences, 2020
Imaging photoplethysmography (iPPG) is a contact-free monitoring of the cutaneous blood volume pulse by RGB (red-green-blue) cameras. It detects vital parameters from skin areas and is associated to cutaneous perfusion. This study investigated the use of

Serial Changes in Right Ventricular Outflow Tract Gradient and Endocarditis Risk After Transcatheter Pulmonary Valve Replacement. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background Infective endocarditis (IE) after transcatheter pulmonary valve replacement (TPVR) remains a significant concern. Although there are overall good short‐term and long‐term hemodynamic outcomes, limited data exist comparing postimplantation echocardiographic findings leading to IE.
