Objective:
To review the results of the valve-sparing operation (David procedure) in patients with aortic root disease.
Methods:
Twenty-nine patients with aortic root disease, 20 males and 9 females, aged 39 +/- 17 (10-64), 10 being of heart functional class I, 15 of class II, and 4 of class III, and 15 with gentle, 9 with moderate, and 5 with severe aortic insufficiency underwent David procedure, one undergoing the aortic valve-sparing reimplantation (David I), 25 undergoing aortic valve-sparing remodeling (David II), and 3 undergoing a new modified aortic valve-sparing operation. After the operation the patients were followed up for 29 +/- 15 months (5-74 months).
Results:
No intra-operative death was found. The mean extracorporeal circulation time was 126 min +/- 25 min, and the aortic crossclamp time was 87 min +/- 22 min. All patients recovered to heart functional class I. Post-operatively 11 patients showed no normal, eight gently and two moderate aortic regurgitation.
Conclusion:
The valve-sparing operation is an ideal operation to the aortic root aneurysm with more or less normal aortic leaflets and valvular ring normal.
