摘要: Long-standing pulmonary insufficiency after repair of tetralogy Fallot may adversely affect ventricular function. We evaluated 20 patients at a mean 9 years by radionuclide ventriculography, 24 hour Holter monitoring, and M-mode echocardiography. The age complete was 7.1 +/- 2.6 years. Patients were divided into groups as follows: Group I (eight patients), no clinical insufficiency; II (12 moderate to severe insufficiency. further divided: IIa, transannular patch (six patients); IIb, patients). There difference between for operation, duration follow-up, right pressure, or ventricular-pulmonary arterial gradient. No patient had residual shunt all in New York Heart Association Class I. Serious dysrhythmias occurred 38% 50% (p = NS). echocardiographic ratio left end-diastolic dimension greater with than those without insufficiency: 0.83 0.17 versus 0.55 0.15, p less 0.01. Right ejection fraction 0.39 0.08 0.27 0.07 II, Left 0.64 0.12 0.53 0.02. Radionuclide angiography is useful means identifying dysfunction following Fallot. appears significantly worse
