Pulmonic Regurgitation is a defect in the valves of the heart that causes return of blood into the right atrium. Some common causes of pulmonic regurgitation include pulmonary hypertension, carcinoid syndrome, and congenital absence of the pulmonary valve, tetralogy of fallot or infective endocarditis. It has also been found that in certain cases involving severe pulmonic regurgitation, right heart failure and right heart ventricular hypertrophy are observed.
However in the case of mild pulmonic regurgitation, the associated symptoms may not be directly related to regurgitation, as they may be related to other underlying problems. The regurgitation is mainly concerned with the backward flow of blood into the right ventricle of the heart during diastole.
The pulmonic regurgitation occurs when the blood passes in the backward direction, from the pulmonary artery and the pulmonary valve into the right ventricle. Although it is not a serious complication, this condition cannot be diagnosed without an ECG. In most cases, medical tests are aimed at identifying other problems; one may actually stumble upon the condition of pulmonary regurgitation during a routine physical test.
In most cases patients who are having the pulmonic regurgitation may not present any symptoms, and this does not require any treatment. But on the other hand, the pulmonary valve may have to be replaced by a surgical procedure .During an EKG the diastolic murmur can be heard as an early decrescendo murmur.
