Long-term results following surgical operation of tetralogy of Fallot.
(1) The ECGs of 84 patients who survived corrective surgery for tetralogy of Fallot were reviewed. The overall incidence of sudden death during at least 5 years period of follow-up was 4%, mortality being highest in those with CRBBB and LAH (40%). (2) The ratio of leftward to rightward QRS forces projected on the X axis (Rs/Sx) is significantly decreased in postoperative T/F patients. (3) Twenty-seven patients who had corrective surgery for tetralogy of Fallot underwent cardiac catheterization postoperatively. LVEF was mildly, but significantly diminished and LVEDV was increased significantly, while peak dp/dt, Vpm and Vmax were significantly depressed. These findings indicate that patients who had corrective surgery for tetralogy of Fallot have impaired left ventricular function.
