It's been almost 4 months since finishing ABVD for IIa. An echocardiogram was done before treatment and another after, and the recent one is showing an "ejection rate" of 40%. (My previous one showed 55%) The nurse says it's due to the Doxorubicin (Adriamycin) and that it may need to be monitored. I had mitral valve prolapse prior to treatment and that part seemed to have remained stable. Anybody out there with a similar situation? Please let me know.
