Abstract:
:To determine efficacy of the Senning procedure for correction of transposition of the great arteries we performed detailed hemodynamic and electrophysiological studies in 6 consecutive children operated upon at 5-18 months of age. Cardiac catheterizations were performed 10-19 months following surgery. All patients were asymptomatic on no medication. Hemodynamic studies demonstrated no evidence of pulmonary venous obstruction, pulmonary hypertension, or left ventricular outflow tract obstruction. 1 patient had mild upper baffle limb obstruction. Angiography demonstrated tricuspid insufficiency in 2 patients and a small atrial level shunt in 1. Ambulatory electrocardiographic monitoring in 5 of 6 patients revealed multiple premature ventricular contractions in 1. Invasive electrophysiological studies for sinus node function were normal. Corrected sinus node recovery time was 36-348 ms while total sinoatrial conduction time, determined in 4 patients, ranged between 83 and 128 ms. At our institution the Senning procedure has a low incidence of residual hemodynamic or electrophysiological abnormalities. Detailed postoperative evaluation is necessary to determine extent of residual problems.
