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.
A pulmonary homograft (a pulmonary valve taken from a cadaver) is then used to replace the patient's own pulmonary valve. This procedure was first performed in 1967 and is used primarily in children, as it allows the patient's own pulmonary valve (now in the aortic position) to grow with the child. [17] Tissue valves can last 10–20 years. [18]
Since the main causes of right ventricular hypertrophy is tricuspid regurgitation or pulmonary hypertension (discussed above), management involves treatment of these conditions. [3] Tricuspid regurgitation is typically treated conservatively by aiming to treat the underlying cause and following up the patient regularly. [ 12 ]
Pulmonary valve stenosis is a crescendo-decrescendo systolic murmur. One can hear it best at the left upper sternal border. It has association with a systolic ejection click that increases with inspiration. This finding results from an increased venous return to the right side of the heart. Pulmonary stenosis sometimes radiates to the left ...
Regurgitation in or near the heart is often caused by valvular insufficiency (insufficient function, with incomplete closure, of the heart valves); for example, aortic valve insufficiency causes regurgitation through that valve, called aortic regurgitation, and the terms aortic insufficiency and aortic regurgitation are so closely linked as ...
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 ...
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.
