RESUMO
Sustained ventricular tachycardia (VT) in the early postoperative period following intracardiac repair for tetralogy of Fallot is rare. In stable VT, amiodarone forms the mainstay of management. However, where amiodarone and other antiarrhythmic drugs are contraindicated, suppressive overdrive atrial pacing can be used as a safe and efficient alternative to maintain cardiac output. We present a case of 1-year 5-month-old child who developed VT with low cardiac output syndrome with deranged hepatic function, who was managed efficiently using suppressive atrial pacing to ameliorate the effects of sustained VT.
RESUMO
Pulmonary atresia with ventricular septal defect and coronary-dependent pulmonary circulation arising from both major coronary arteries is rare. Dependence of pulmonary blood flow on the coronaries and the risk of early development of pulmonary vascular obstructive disease warrant early surgical repair in these patients. We report a case of a ten-month-old infant with pulmonary atresia with ventricular septal defect and coronary artery-to-main pulmonary artery connections who was successfully managed with ligation of the coronary fistulas and intracardiac repair.
