Posterior pulmonary artery bifurcation side-to-side arterioplasty for branch pulmonary artery stenosis

A case of isolated peripheral pulmonary artery branch stenosis associated with multiple pulmonary artery aneurysms.

Selective right pulmonary arteriography and 3-dimensional computed tomography revealed multiple severe stenoses of the peripheral pulmonary artery associated with poststenotic aneurysms in a 65-year-old woman. She was referred to the hospital for evaluation of dry cough, gradually increasing dyspnea and multiple nodular shadows on a chest radiograph. Echocardiography and cardiac catheterization...

Pulmonary artery stenosis.

SINCE the description by Mbller' in 1953 of stenosis of peripheral pulmonary arteries, this congenital lesion has been recognized with increasing frequency. The lesion is of interest both from a clinical and physiologic standpoint. From the latter standpoint, there is sufficient documentation to warrant the inclusion of this congenital anomaly as one of the causes of right ventricular hypertens...

Diastolic prolongation of forward flow in branch pulmonary artery stenosis

Diastolic prolongation of forward flow, or diastolic tail is present in unilateral branch pulmonary artery stenosis in patients after the arterial switch operation for transposition of the great arteries and after repair for tetralogy of Fallot. Interestingly, as a result of a diastolic tail, flow through the stenosed artery is comparable to that in the non-stenosed artery and therefore the imp...

Acquired pulmonary stenosis and pulmonary artery compression.

Pulmonary artery stenosis after systemic-to-pulmonary shunt operations.

OBJECTIVE Systemic-to-pulmonary shunt operations are still required for palliation of certain congenital heart defects. The aim of this study was to analyze the incidence and etiology of the development of pulmonary artery stenosis after these procedures. METHODS AND RESULTS Pre- and post-operative angiograms of 59 patients who underwent 54 peripheral and 12 central shunt operations were anal...
