Pulmonary (or pulmonic [4]) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent [5] and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole. [6] While a small amount of backflow may occur ordinarily, it is usually only shown on an echocardiogram and ...
A Wiggers diagram modified from [1]. A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century.
pulmonary regurgitation A Graham Steell murmur is a heart murmur typically associated with pulmonary regurgitation . [ 1 ] [ 2 ] It is a high pitched early diastolic murmur heard best at the left sternal edge in the second intercostal space with the patient in full inspiration , originally described in 1888.
The presence of this murmur is a good positive predictor for AR and the absence of this murmur strongly suggests the absence of AR. An Austin Flint murmur is usually associated with significant aortic regurgitation. Early diastolic Pulmonary regurgitation: Pulmonary regurgitation is most commonly due to pulmonary hypertension (Graham-Steell ...
Wiggers diagram of various events of a cardiac cycle, with 2nd heart sound at bottom.. A split S2 is a finding upon auscultation of the S2 heart sound. [1]It is caused when the closure of the aortic valve (A 2) and the closure of the pulmonary valve (P 2) are not synchronized during inspiration.
Tricuspid regurgitation Intensifies upon inspiration. Can be best heard over the fourth left sternal border. The intensity can be accentuated following inspiration (Carvallo's sign) due to increased regurgitant flow in right ventricular volume. Tricuspid regurgitation is most often secondary to pulmonary hypertension.
Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.
