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 ...
The degree of pulmonary regurgitation with right or left ventricular dysfunction, as well as the level of pulmonary hypertension, are linked to an increased risk of pregnancy complications. [71] Fetal death is more likely in women who have moderate right ventricular hypertension or who have undergone a palliative shunt.
Pulmonary function testing is a safe procedure; however, there is cause for concern regarding untoward reactions and the value of the test data should be weighed against potential hazards. Some complications include dizziness, shortness of breath, coughing, pneumothorax, and inducing an asthma attack.
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 (PVS) is a heart valve disorder. Blood going from the heart to the lungs goes through the pulmonary valve, whose purpose is to prevent blood from flowing back to the heart. In pulmonary valve stenosis this opening is too narrow, leading to a reduction of flow of blood to the lungs. [1] [5]
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 ...
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.
