An evaluation of cases carried out by both root reconstruction using Carrel patch method and concomitant procedure

Abstract

During the past 7 years from January 1991 to November 1997, we experienced 31 cases of aortic root reconstruction utilizing Carrel patch method. Concomitant procedure were performed in 9 cases of them due to another cardiovascular disease. Complicated cardiovascular disease included 3 cases of ischemic heart disease, 3 cases mitral regurgitation and one case of Aortic arch aneurysm. Several concomitant procedures were performed; 5 cases of CABG, 2 cases of mitral annuloplasty, one case of CABG with mitral valve replacement and one case of aortic arch replacement. The mean extra corporeal circulation time was 190.6 +/- 39.3 minutes and aortic clamp time was 147.8 +/- 34.2 minutes in these 9 cases. There were no significant differences of operative results between the simple root reconstruction group and the concomitant procedure group. We concluded that the aortic root reconstruction using the Carrel patch method has few complications. Although further long-term follow-up is required, our experiences suggest that the aortic root reconstruction with the concomitant procedure can be carry out safely with the aid of appropriate assistance method.
