[Long-term results of valvular condition and clinical state in patients operated with the Senning method].

8 patients suffering transposition of the great arteries (d-TGA) aged from 8-17 years (mean 12.6 years) after Senning procedure performed were analyzed. Right atrium and right ventricle enlargement was detected in all patients. Small jet tricuspid valve regurgitation was confirmed in 5 patients, significant tricuspid valve insufficiency in 3 patients. 4 patients had presented with tricuspid valve, aorta valve and mitral valve insufficiency. In one patient insignificant pulmonary artery stenosis had been diagnosed. Chronic cardiac failure (NYHA III/IV) has been diagnosed in 2 patients, other patients from the analyzed group are in good clinical condition. All patients but 2 were diagnosed with arrhythmia using 24-hour Holter ECG. In 2 patients sinus node dysfunction was noted. Also supraventricular extrasystole, ventricular extrasystole, supraventricular tachycardia, ventricular salve, paroxysmal atrial fibrillation were described. No drug therapy in 4 patients is needed, one is treated with ACE-inhibitors, one with diuretic drugs. 2 patients suffering cardiac failure had been treated with 4 drugs, also temporary with intravenous dopamine. One death had been noted, caused by serious arrhythmia. One patient had been qualified for heart transplantation, there is no further data regarding this case. Senning procedure can be considered high risk for various problems, so patients who underwent this type of correction should be carefully observed.
