Because pulmonic regurgitation is the result of other factors in the body, any noticeable symptoms are ultimately caused by an underlying medical condition rather than the regurgitation itself. [3] However, more severe regurgitation may contribute to right ventricular enlargement by dilation, and in later stages, right heart failure . [ 8 ]
Pulmonary valve diseases are the least common heart valve disease in adults. [1] [4] Pulmonary valve stenosis is often the result of congenital malformations and is observed in isolation or as part of a larger pathologic process, as in Tetralogy of Fallot, Noonan syndrome, and congenital rubella syndrome. Unless the degree of stenosis is severe ...
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. [1]
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]
Ultrasound showing aortic regurgitation and vegetations on the aortic valve. [19] In terms of the diagnosis of aortic regurgitation a common test for the evaluation of the severity is transthoracic echocardiography, which can provide two-dimensional views of the regurgitant jet, allow measurement of velocity, and estimate jet volume.

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. [ 1 ] [ 2 ] In the Wiggers diagram, the X-axis is used to plot time subdivided into the cardiac phases, while the Y-axis typically contains the following ...
In The Framingham Heart Study presence of any severity of tricuspid regurgitation, ranging from trace to above moderate was in 82% of men and in 85.7% of women. [2] Mild tricuspid regurgitation tend to be common and benign and in structurally normal tricuspid valve apparatus can be considered a normal variant. [1]
The treatment of acute respiratory failure may involve medication such as bronchodilators (for airways disease), [7] [8] antibiotics (for infections), glucocorticoids (for numerous causes), diuretics (for pulmonary oedema), amongst others. [1] [9] [10] Respiratory failure resulting from an overdose of opioids may be treated with the antidote ...
