Transplantation is effective therapy for congestive heart failure (CHF),
but few donors are available and many patients are not candidates. We have
therefore developed a surgical approach to CHF that offers several options.
Patients with no medical or psychosocial contraindications are listed for
heart transplantation (HT). Patients with ischemia on thallium scan and
operable vessels have coronary artery bypass grafting (CABG). Patients who
are not candidates for either of these options are evaluated for
cardiomyoplasty (CMP). One hundred nineteen patients have now had operation
for CHF: 61 had HT, 27 had CABG, and 31 had CMP. The mean ages of the three
groups were 51 +/- 1 years, 59 +/- 3 years, and 56 +/- 2 years,
respectively. Preoperative pulmonary capillary wedge pressure was 22 +/-
1.1 mm Hg in the HT group, 20 +/- 2.9 mm Hg in the CABG group, and 19 +/-
1.9 mm Hg in the CMP group. Left ventricular ejection fraction improved in
operative survivors in each group: 0.23 +/- 0.01 to 0.69 +/- 0.01 for the
HT group, 0.31 +/- 0.01 to 0.39 +/- 0.02 for the CABG group, and 0.26 +/-
0.01 to 0.33 +/- 0.03 for the CMP group (p < 0.01). The operative
mortality rate was 7% for the HT patients, 4% for the CABG patients, and
16% for the CMP patients, and 1-year survival rates for those discharged
were 94%, 91%, and 65%, respectively. Long-term survivors of CMP and CABG
are functionally improved but still require medical therapy for CHF.
Survivors of HT do not have CHF but suffer the consequences of
immunosuppression.(ABSTRACT TRUNCATED AT 250 WORDS)
