[Quantitative assessment of hemodynamics function in treadmill test in patients after radical correction of Fallot's...

Long-term examination findings in 78 patients after radical correction of Fallot's tetralogy and preoperative assessment of the circulatory status in 68 patients using treadmill test are analysed. The quantitative estimates of circulatory defects at different levels at later postoperative terms (from 6 months to 6 years) depended on the type of plastic surgery of the outflow part of the right ventricle and pulmonary trunk: suture plasty, right ventricular outflow plasty with a xeno-pericardial flap, and transannular plasty with the use of a mono-septal xeno-pericardial graft. Preoperatively, 59.0 per cent patients were attributed to functional class IV and 41.0 per cent patients to class III. After the radical tetralogy correction, most patients (55.0 per cent) were related to the functional class I. The advantages of using mono-septal xeno-pericardial grafts for plastic surgery of the right ventricular outflow and pulmonary trunk are demonstrated.
