Long-term cardiopulmonary exercise capacity after modified Fontan operation.
OBJECTIVE Early circuit separation enhances the long-term success of Fontan haemodynamics. To test this hypothesis, we analysed the postoperative cardiopulmonary capacity in children and adults. PATIENTS Spiroergometry was performed at least twice in 43 patients with a median age of 14 (range: 7-43) years, with a median time interval of 4.6 (1.1-10.4) years between early and late testing. Twe...
متن کاملReconstruction of a new pulmonary artery in arterial switch operation.
BACKGROUND This study was undertaken to evaluate the new method for the reconstruction of the pulmonary artery in arterial switch operation (ASO). METHODS A total of 108 consecutive infants with congenital heart disease were treated with ASO in our department between January 2004 and June 2012. The new pulmonary arterial root was reconstructed with a fresh autologuos pericardium which was cli...
متن کاملDecreased incidence of supravalvar pulmonary stenosis after arterial switch operation.
BACKGROUND Supravalvar pulmonary stenosis (SVPS) is frequently observed after arterial switch. Traditionally the coronary arteries are removed from the neopulmonic root by excising the entire sinus of Valsalva. As a result, reconstruction of the neopulmonic root requires a pericardial patch encompassing two-thirds of the anastomosis between the neopulmonic root and pulmonary artery. We present ...
متن کاملPulmonary artery pressure limits exercise capacity at high altitude.
Altitude exposure is associated with decreased exercise capacity and increased pulmonary vascular resistance (PVR). Echocardiographic measurements of pulmonary haemodynamics and a cardiopulmonary exercise test were performed in 13 healthy subjects at sea level, in normoxia and during acute hypoxic breathing (1 h, 12% oxygen in nitrogen), and in 22 healthy subjects after acclimatisation to an al...
متن کاملPulmonary arterial compliance and exercise capacity after pulmonary endarterectomy.
Patients with chronic thromboembolic pulmonary hypertension (CTEPH), despite successful pulmonary endarterectomy (PEA), can continue to suffer from a limitation in exercise capacity. The objective of this study was to assess whether pulmonary arterial compliance is a predictor of exercise capacity after PEA. Right heart haemodynamics, treadmill incremental exercise test, spirometry, carbon mono...
