Computational Simulations for Aortic Coarctation: Representative Results From a Sampling of Patients [PDF]

, 2011
Treatments for coarctation of the aorta (CoA) can alleviate blood pressure (BP) gradients(D), but long-term morbidity still exists that can be explained by altered indices of hemodynamics and biomechanics.

Hepatopulmonary syndrome as presentation of pediatric metabolic dysfunction‐associated steatohepatitis

JPGN Reports, EarlyView.
Abstract Childhood obesity is rising and leading to serious co‐morbidities, among which is metabolic dysfunction‐associated steatotic liver disease (MASLD) predisposing individuals to cirrhosis. We describe a young 11‐year‐old Hispanic male who presented with hepatopulmonary syndrome secondary to cirrhotic portal hypertension from metabolic dysfunction‐

Pre‐ and Post‐Interventional Hemodynamic Characterization of the Femoropopliteal Artery Using Vector Flow Imaging in Peripheral Arterial Occlusive Disease

Journal of Ultrasound in Medicine, EarlyView.
Objectives The femoropopliteal (FP) artery is the most frequently revascularized segment in peripheral artery disease (PAD), followed by the iliac segment. Wall shear stress (WSS) is a key local factor implicated in both atherosclerotic plaque formation and restenosis after angioplasty.
