Core Tip
Core Tip: A 31-year-old woman diagnosed with postpartum pulmonary embolism was readmitted to hospital, when conventional echocardiography found pulmonary artery hypertension. Right-heart contrast echocardiography showed microbubbles appearing in the left ventricle, with a slight delay after right-heart filling with microbubbles but no microbubbles in the left atrium; microbubbles also appeared in the descending aorta almost simultaneously to the right pulmonary artery. Computed tomography angiography showed no sign of pulmonary artery embolism but did show a patent ductus arteriosus. Ultimately, right-heart contrast echocardiography showed a special imaging sequence for unexplained pulmonary artery hypertension with aortic valve insufficiency and simultaneous patent ductus arteriosus.
