Successful Allogeneic Stem Cell Transplant in Pediatric Patients With Diminished Left Ventricular Ejection Fractions.

ABSTRACT

Chemotherapy-associated cardiotoxicity may delay or impair the ability to administer fully myeloablative chemotherapy for stem cell transplant in those with reduced left ventricular ejection fraction. Studies in adults have been inconsistent regarding the value of ejection fraction in predicting cardiotoxicity in the posttransplant period. Recent publications, however, have demonstrated successful stem cell transplantation in adults despite low ejection fractions. This case series highlights 2 pediatric patients who were successfully treated with stem cell transplantation without posttransplant cardiac complications, despite pretransplant ejection fractions of 38% and 29%.
