Pathophysiology of right ventricular volume/pressure load
HF/RV function & TR Educational Series: Episode #2
Summary
Follow Karl-Philipp Rommel as he shares insights on physiology relevant to diagnosing and treating TR-related right heart failure.
In this video you will learn:
- to recall the unique physiology of right ventricular function
- to understand the implications of RV pressure and volume load using the pressure-volume-loop framework
- to illustrate the concept of right ventricular-pulmonary arterial (RV-PA) coupling
Take-home messages of Episode #2
- RV function: a unique contraction pattern and physiology
- RV-PA coupling: indexes RV function (contractility) to afterload and describes the match of RV and PA properties to optimize RV performance
- Tricuspid regurgitation: RV energetic efficiency↓ (stroke work↑ but cardiac output↓), further aggravated by RV dysfunction, effective RV afterload↓
- Chronic RV volume overload: low RV contractility and low contractile reserve
