Right Ventricular Dysfunction During Endurance Exercise as Determined by Pressure-Volume Analysis

A 37-year-old athlete completed invasive endurance (90 km) bicycle exercise testing for right ventricular pressure-volume analysis. Increased right ventricular afterload caused declines in ventricular-arterial coupling and cardiac output, causing increased arteriovenous oxygen difference to maintain...

Descripción
Sumario:A 37-year-old athlete completed invasive endurance (90 km) bicycle exercise testing for right ventricular pressure-volume analysis. Increased right ventricular afterload caused declines in ventricular-arterial coupling and cardiac output, causing increased arteriovenous oxygen difference to maintain oxygen uptake. These findings demonstrate effects of changes in right ventricular performance on exercise capacity. (Level of Difficulty: Intermediate.)
