Original Articles“I” ministernotomy for aortic valve replacement
Section snippets
Material and methods
Eighteen randomly selected patients, 11 men and 7 women, 25 to 73 years old (mean, 55.1 years), were operated on for isolated aortic stenosis (10 patients) or aortic regurgitation (8 patients) through an “I” ministernotomy at Chang Gung Memorial Hospital, Taipei, Taiwan (MINI group). Patients associated with coronary artery disease, mitral or tricuspid valvular disease, severe aortoiliac occlusive disease, or severe atherosclerotic disease of the ascending aorta were excluded from this
Results
Aortic valve replacements were performed in all patients. Conversion to full sternotomy did not occur in any patient of the MINI group. The length of skin incision was significantly shorter in patients of the MINI group (Table 2). The aortic cross-clamping time was 40 to 78 minutes (65 ± 8 minutes, mean ± standard deviation) in patients of the MINI group and was 30 to 52 minutes (40 ± 5 minutes) in those of the FS group (p < 0.05) (Table 2). The total bypass time was 55 to 90 minutes (77 ± 7
Comment
In this report, 18 patients were operated on successfully by “I” ministernotomy for aortic valve lesion. Compared with 16 patients operated on through full sternotomy, the incision length was shortened, the incisional pain was reduced, the hospital stay was decreased, and the recovery was enhanced. This indicates that ministernotomy is technically feasible and may be a good alternative procedure in the surgical treatment of aortic valve lesions.
