Since the first introduction of pulmonary balloon valvuloplasty by Kan in 1982, the procedure has been used for relief of pulmonary valve stenosis. It is normally recommended that the procedure should be performed for peak-topeak gradients in excess of 50 mm Hg,1 and the balloon/ annulus ratio should be 1.2 to 1.25 for effective and safe results.2 Complications of the procedure are minimal and ...

Scanning suprasternal echocardiography was performed in 280 patients with a variety of cardiac anomalies. By using the special suprasternal transducer on the suprasternal notch, the aortic arch, right pulmonary artery, and left atrium were recorded superoinferiorly. From this reference position various scanning techniques were made to record the main pulmonary artery, pulmonary valve, ascending...

A 36-year-old woman was seen with complaints of exertional chest pain and shortness of breath. Her medical history included atrial fibrillation and diabetes. Physical examination was unremarkable except for an irregular cardiac rhythm. Myocardial perfusion imaging revealed the presence of a large area of infarction involving the entire anterior and apical walls and part of the anteroseptal wall...

We present a rare case of main pulmonary artery stenosis secondary to protruding fibrous material in the main pulmonary artery associated with patent ductus arteriosus. A 1-month-old baby boy manifested cardiac murmur. Echocardiogram showed circumferential high echogenic mass inside the main pulmonary artery with pressure gradient of 49 mmHg and patent ductus arteriosus. The mass did not regres...

Pulmonary arterial dilatation associated with pulmonary hypertension may result in significant compression of local structures. Left main coronary artery and left recurrent laryngeal nerve compression have been described. Tracheobronchial compression from pulmonary arterial dilatation is rare in adults, and there are no reports in the literature of its occurrence in idiopathic pulmonary arteria...

PURPOSE Massive pulmonary embolism (PE) causes hemodynamic compromise and is associated with a high rate of mortality. We sought to create a model of massive PE and to determine whether occlusion of the right main bronchus could mitigate the physiological effects of massive PE in this model. MATERIALS AND METHODS We used 27 female sheep to generate a model of massive PE by either autologous b...

CONTEXT AND OBJECTIVE The location of embolism is associated with clinical findings and disease severity in cases of acute pulmonary embolism. The level of gamma-glutamyl transferase increases under oxidative stress-related conditions. In this study, we investigated whether gamma-glutamyl transferase levels could predict the location of pulmonary embolism. DESIGN AND SETTING Hospital-based cr...

Figure 2: Intraoperative view. The main right pulmonary artery dissected proximally and distally to expose the lesion (A). The opened aneurysm (B). Three segmental arteries arising from the aneurysmal sac (arrows). Surgical ties placed around the main pulmonary artery proximal and distal to the aneurysm and around the segmental branches. RUL: right upper lobe; VCS: vena cave superior; RPA: righ...
