Flow murmur associated with partial occlusion of the right pulmonary artery.
An 18-year-old male student presented with a brief history of syncope followed by shortness of breath with exertion, and the development of murmur over the right chest. The symptoms and murmurs were related to a pulmonary embolus which partially occluded the right pulmonary artery and its major branches. The murmur gradually diminished and disappeared when right pulmonary perfusion had almost returned to normal as determined by lung scan. The association of pulmonic flow murmurs and pulmonary emboli is reviewed.
