title: Early benefit of implantable cardioverter defibrillator therapy in patients waiting for cardiac transplantation.
abstract: The ICD can effectively recognize and treat ventricular arrhythmias that can lead to sudden death. Sudden death is a major problem in patients awaiting heart transplantation. We reviewed our experience with the ICD in patients with malignant ventricular arrhythmias waiting for cardiac transplantation. Nineteen patients were included. Seventeen were men, mean age was 54 +/- 11 years (range 17-66) and the left ventricular ejection fraction was 22% +/- 10% (range 9%-46%). After a mean follow-up of 6 +/- 5 months (range 1-20 months), 17 patients reached heart transplantation. One patient died and the other is waiting for a transplant. Before transplantation 71% of patients received an appropriate discharge. The mean time to the first appropriate discharge was 2 +/- 2 months (range < 1-6 months), which was significantly shorter than the mean time to first discharge in the other patients (n = 182) receiving a defibrillator in our center (11 +/- 10 months; range 1-58 months) (P < 0.0004). In conclusion, cardiac transplantation candidates with life-threatening ventricular arrhythmias can effectively be protected against sudden arrhythmic death by ICD. These patients have a high incidence of appropriate shocks occurring very early after implantation.
