When there is an obstacle or stenotic heart valve, it is known as pulmonary valve disease. To treat this blockage or clots, balloon pulmonary valvuloplasty is used, which is also called balloon valvotomy. In common, pulmonary valves manage the deoxygenated blood from the heart to the lungs. This valve is situated between the right ventricle and the pulmonary artery in the heart. https://healthcheckbox.com/cardiology/balloon-pulmonary-valvuloplasty/
