Severe left-to-right shunting from combined traumatic tricuspid valve rupture and atrial septal defect: bridge to surgical repair using veno-venous ECMO.

Our patient presented to the emergency room following a motor vehicle accident. The traumatic tricuspid valve rupture was diagnosed by transthoracic echocardiogram, and his respiratory status declined rapidly. He was placed on veno-venous extracorporeal membrane oxygenation (VV ECMO) to bridge him to surgical repair.

Critical Information from High Fidelity Arterial and Venous Pressure Waveforms During Anesthesia and Hemorrhage.

Purpose: Peripheral venous pressure (PVP) waveform analysis is a novel, minimally invasive, and inexpensive method of measuring intravascular volume changes. A porcine cohort was studied to determine how venous and arterial pressure waveforms change due to inhaled and infused anesthetics and acute hemorrhage.

Methods: Venous and arterial pressure waveforms were continuously collected, while each pig was under general anesthesia, by inserting Millar catheters into a neighboring peripheral artery and vein.
