Aortogram showed complete opacification of the LV. (Movie II in the online-only data supplement). These findings are pathognomonic for acute severe aortic regurgitation. Figure 1. M-mode echocardiography showing type A early closure of the mitral valve with diminished A wave ( arrow ). 1. Figure 2.
Hemodynamic changes of aortic regurgitation - PubMed

Hemodynamic changes of aortic regurgitation. Hemodynamic changes associated with acute AR include a rapid increase in LV pressures during diastole, markedly elevated pressures at end diastole, and premature closure of the mitral valve. Systemic diastolic pressures may be low, but there is a minimal increase in pulse pressure.
Hemodynamic Assessment of Aortic Regurgitation After …
https://pubmed.ncbi.nlm.nih.gov/27131441/
Abstract Objectives: Assessment of aortic regurgitation (AR) immediately after transcatheter aortic valve replacement (TAVR) is essential to guide further intervention in cases of relevant AR. It was the aim of this study to identify a simple and reproducible hemodynamic parameter for the assessment of AR.

Complete Hemodynamic Evaluation of Patients With Aortic Regurgitation by Outpatient Right Heart Catheterization and Digital Subtraction Angiography - PubMed. The aim of this study was to demonstrate that total hemodynamic evaluation of patients with aortic regurgitation can be performed on an outpatient basis by combining right heart catheterization with digital …
Quantitative assessment of the hemodynamic …
https://pubmed.ncbi.nlm.nih.gov/3298358/
The purpose of this study was to evaluate the ability of continuous wave Doppler ultrasound recordings to reflect the magnitude and hemodynamic effects of aortic regurgitation. Forty-five patients with angiographically proved aortic regurgitation had Doppler studies performed within 24 hours of cardiac catheterization.

The hemodynamic alterations of aortic regurgitation form the basis for understanding the clinical, invasive, and echocardiographic manifestations of the disease and have practical applications to appreciating complications during transcatheter aortic valve replacement (TAVR). The classical physical findings of chronic aortic insufficiency, wide pulse …

The aortic valve separates the left ventricle from the aorta. The hemodynamic changes associated with aortic regurgitation (AR) differ depending on the time–course of the valve dysfunction. In chronic AR, stroke volume increases to maintain effective forward flow. This causes dilation of the LV, leading in some patients to the development of a massively dilated …

To obtain proper hemodynamic tracings, 6F or even 7F catheters may be required if the smaller catheters do not produce high-quality pressure contours. Catheters with side holes should be used to measure ventricular pressures. Catheters with end holes should be used to measure wedge pressures.
