Focal Atrial Tachycardia in a Patient With Surgically Corrected Tetralogy of Fallot
نویسندگان
چکیده
Tetralogy of Fallot (TOF) is a cyanotic congenital heart disease which, without corrective surgery, has a poor prognosis. These patients have an increased incidence of arrhythmias both supraventricular and ventricular post surgical correction. The supraventricular arrhythmias are usually related to the scar tissue at the surgical repair site. We present a case of a young male patient status post TOF repair who presented with a supraventricular tachycardia which was found to be unrelated to his surgical scar.

Life threatening ventricular tachycardias in late survivors of surgically corrected tetralogy of Fallot.
Electrophysiological tests were performed in three patients with surgically corrected tetralogy of Fallot (mean age at evaluation 25 years, mean age at surgical correction 4 years) who had had either a cardiac arrest or transient neurological disturbances (presyncope, syncope) associated with ventricular arrhythmias. All three patients had an excellent haemodynamic result from surgery as judged...
متن کاملProduction of Increased Right - to - Left Shunting by Rapid Heart Rates in Patients with Tetralogy of Fallot By SPENCER
A patient with tetralogy of Fallot who developed cyanosis and tachypnea during spontaneous attacks of paroxysmal atrial tachycardia had an increase in right-to-left shunting with a fall in arterial oxygen saturation from 96 to 43%. Duplication of the fast heart rate by atropine and atrial pacing reproduced these hemodynamic changes, while slowing the rate with propranolol reversed this effect. ...

متن کاملPearls for ablation in congenital heart disease.
Tachyarrhythmias occur in patients having congenital heart disease most commonly related to surgically created or naturally occurring conduction obstacles, and to postoperative hemodynamic effects on cardiac muscle. Less frequently, the underlying disease is associated with tachycardia substrates. Thorough knowledge of the patient's congenital anatomy and surgical procedures is required before ...
متن کاملRight atrial volume and body mass index in corrected tetralogy of Fallot correlate with the incidence of supraventricular arrhythmia - an MRI study
Background Patients with corrected Tetralogy of Fallot (cTOF) can develop supraventricular arrhythmias. So far, right atrial (RA) volume in TOF has not been evaluated in the context of arrhythmia. The aim of this study was to evaluate if right atrial (RA) volume in TOF correlates with the occurrence of supraventricular arrhythmias. To identify other risk factors for arrhythmias additional param...
