The authors' experience is reported of cardiac reoperations for valvular heart disease in octogenarian patients.The records of 22 consecutive patients (10 men, 12 women) agedor =80 years (mean age 82.4+/-2.3 years) who underwent cardiac reoperation for aortic and/or mitral valvular heart disease at the authors' institution between 1991 and 2001 were retrospectively reviewed.Indications for reoperation were structural dysfunction of a previously implanted bioprosthetic valve in 11 patients (50%), new valvular heart disease in six (27%), progression of rheumatic valvular heart disease in four (18%), and prosthetic valve infective endocarditis in one patient (5%). Fourteen patients (64%) underwent isolated aortic valve replacement (AVR), two (9%) had AVR plus coronary artery bypass grafting (CABG), one patient (5%) had aortic root replacement plus CABG, three patients (14%) had isolated mitral valve replacement (MVR), one patient (5%) had MVR plus ascending aorta replacement, and one (5%) had AVR plus MVR. Postoperative complications occurred in 18 patients (82%). The hospital mortality rate was 32%. Actuarial survival estimates at one year, and at three and five years were 62.6%, 56.3% and 40.2%, respectively.Cardiac reoperations for valvular heart disease in octogenarians carry a high postoperative morbidity and mortality. These findings must be taken into account in the management of associated mild or moderate valvular heart disease, and in the choice of heart valve prosthesis at the initial operation in younger patients. |
