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...
متن کاملOutcomes of Pulmonary Valve Replacement for Correction Pulmonary Insufficiency after Primary Repair of Tetralogy of Fallot (TOF)
Background Total correction of Tetralogy of Fallot (TOF) anomaly in early childhood has been practiced in many centers with good results, but in some of patients after few years sever Pulmonary valve insufficiency occurred. Materials and Methods At a cross- sectional study from January 2015 to January 2016, 10 patients who had history of primary repair of TOF with free pulmonary insufficiency (...
متن کاملDiastolic 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...
متن کاملPulmonary Valve Repair for Patients With Acquired Pulmonary Valve Insufficiency.
BACKGROUND Pulmonary valve (PV) insufficiency is often an acquired condition after treatment for pulmonary stenosis. It is recognized that PV insufficiency has serious deleterious effects. Although surgical replacement of the PV is efficacious, artificial valves inevitably fail and require re-intervention. The purpose of this study was to summarize our experience with PV repair in patients with...
متن کاملPulmonary 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...
