Etiology of right bundle-branch block in patients undergoing total correction of tetralogy of Fallot.

چکیده
curs routinely in patients after open-heart surgery for tetralogy of Fallot (TF). To determine the etiology of the RBBB pattern, 14 patients with TF, seven with ventricular septal defects (VSD), and one with pulmonary stenosis (PS) were studied during and after cardiac surgery. Bipolar electrograms from 10 selected right ventricular epicardial sites were recorded simultaneously with an ECG. Records were obtained before and immediately after vertical right ventriculotomy, after infundibular resection, and after repair of a ventricular septal defect (VSD). The vertical ventriculotomy alone

Sudden Death Among Postoperative Patients with Tetralogy of Fallot
Two hundred and forty-three patients were evaluated following total correction of tetralogy of Fallot with special emphasis on postoperative conduction disturbances and on the occurrence of sudden death. The average follow-up period was 12 years with a range of 61/2 to 161⁄2h years. Sudden death occurred in seven patients. Four deaths were among those with right bundle branch block pattern (RBB...
متن کاملIs Right Bundle Branch Block Avoidable in Surgical Correction of Tetralogy of Fallot?
Right bundle branch block (RBBB) is usually considered almost unavoidable after repair of tetralogy of Fallot (TOF). By modifications of the standard technique, its frequency has been decreased to 32% in a series of 100 consecutive patients. These modifications are: (1) a very short right ventricular incision, avoiding the ventriculotomy-induced RBBB pattern; (2) an infundibular resection limit...

Combined left anterior hemiblock and right bundle-branch block after surgical closure of ventricular septal defects and correction of tetralogy of Fallot is evaluated in 240 patients. It wasfound that 7 of IO9 patients or 6-4 per cent with ventricular septal defect and I4 of I3I patients or IO-7 per cent with tetralogy of Fallot developed this combination of conduction disturbances as a consequ...
متن کاملThe mechanism of apparent right bundle branch block after transatrial repair of tetralogy of Fallot.
The electrocardiographic pattern of right bundle branch block (RBBB) is routinely observed after transatrial repair of tetralogy of Fallot even though no ventriculotomy has been performed. The mechanism of this conduction disturbance was studied in 16 patients with tetralogy of Fallot and one patient with infundibular pulmonic stenosis. Preoperative ECGs and vectorcardiograms showed right ventr...
