Abnormal cardiac autonomic nervous activity after right ventricular outflow tract reconstruction.
BACKGROUND There are few studies of cardiac autonomic nervous activity (CANA) in patients with congenital heart disease. Methods and Results-We evaluated CANA in 54 patients after closure of an atrial/ventricular septal defect (group A), 54 patients after successful right ventricular outflow tract reconstruction (RVOTR) (group B1), 35 RVOTR patients with residual stenosis (group B2), and 47 con...
متن کاملAbnormal postexercise cardiovascular recovery and its determinants in patients after right ventricular outflow tract reconstruction.
BACKGROUND Abnormal responses of heart rate (HR) and oxygen uptake (VO2) during exercise characterize patients after right ventricular outflow tract reconstruction (RVOTR) for congenital heart defects. However, little is known about the postexercise dynamics. METHODS AND RESULTS We evaluated postexercise cardiovascular dynamics in 52 patients after closure of an atrioventricular septal defect...
متن کاملThe Role of Autonomic Nervous System on Right Ventricular Outflow Tract Tachycardia
Background: Right ventricular outflow tract ventricular tachycardia (VT) and ventricular premature complexes (VPCs) are characterized as benign in entity with ECG morphology showing LBBB pattern and inferior axis. Pathogenic mechanisms in the genesis of RVOT VT/VPC remain largely unknown. We aimed to investigate the neural mechanism in RVOT VT/VPC in canine model. Methods: Twelve mongrel dogs (...
متن کاملRight ventricular outflow tract reconstruction with an allograft conduit.
BACKGROUND Allograft conduits are used for reconstruction of the right ventricular outflow tract in patients with congenital heart disease and in the pulmonary autograft procedure. A retrospective evaluation of our experience with the use of allograft conduits for reconstruction of the right ventricular outflow tract was conducted. METHODS Between August 1986 and March 1999, 316 allografts (2...
متن کاملRight ventricular outflow tract reconstruction with bicuspid valved polytetrafluoroethylene conduit.
BACKGROUND In general, all conduits available for right ventricular outflow tract (RVOT) reconstruction eventually become stenotic or insufficient. Owing to the lack of an ideal conduit and with the hope of reducing the incidence of reoperations, we have developed and utilized a bicuspid valved polytetrafluoroethylene (PTFE) conduit for the reconstruction of the RVOT. The purpose of this study ...
