A 34-year-old woman was admitted to the hospital because of recently aggravated right heart failure without angina for 5 months. When she was 25 years old, patch repair with Polytetrafluoroethylene (PTFE) was performed for the secondum type of atrial septal defect (ASD) with moderate pulmonary hypertension. The chest PA, echocardiography and cardiac catheterization at current admission revealed...

We experienced the surgical repair of an extremely rare pulmonary artery dissection without pulmonary hypertension. The patient had multiple coronary-pulmonary artery fistulae, which presumably caused pulmonary artery dissection. The surgical treatment included the closure of the multiple coronary fistulae and the resection of the intimal flap in the main pulmonary artery. The patient recovered...

Coronary artery fistulas have been diagnosed with aortography, coronary angiography, and coronary computed tomography (CT). A large fistula can be occasionally found as a mass lesion on echocardiography but cannot be easily confirmed. Here, we report a new diagnostic approach to coronary artery fistulas using a contrast agent and transthoracic echocardiography. Transthoracic echocardiography of...

Extrinsic compression of the left main coronary artery by a massively dilated pulmonary artery in patients who have severe pulmonary hypertension can lead to significant myocardial ischemia. A 58-year-old man with a large patent ductus arteriosus and Eisenmenger syndrome presented with angina at rest and worsening heart failure of 3 months' duration. The new symptoms were recognized to be secon...

In order to delineate further the function of the main pulmonary artery as a receptor site, a specially designed Laks triple-lumen balloon catheter was inserted transvenously and positioned in the main pulmonary artery. In six conscious nonsedated dogs, inflation of a balloon in the main pulmonary artery produced acute reversible pulmonary arterial hypertension; the pressure beyond the balloon ...

OBJECTIVE We evaluated the efficacy of the early rehabilitation of remnant pulmonary artery in unilateral absent intrapericardial pulmonary artery and the factors affecting pulmonary artery growth. METHODS We retrospectively reviewed the medical records and imaging modalities of 15 patients with unilateral absent intrapericardial pulmonary artery (7 left and 8 right; median age at diagnosis, ...

BACKGROUND Pulmonary hypertension is a disease characterized by an elevation in pulmonary arterial pressure that is diagnosed invasively via right heart catheterization. Such pathological altered pressures in the pulmonary vascular system should lead to changes in blood flow patterns in the main pulmonary artery. METHODS AND RESULTS Forty-eight subjects (22 with manifest pulmonary hypertensio...
