Successful surgical treatment for total circumferential aortic and mitral annulus calcification: application of half-and-half technique.
Patients with total circumferential mitral annular calcification (MAC) extending into the intervalvular fibrous body and aortic annulus have a high risk of cardiac surgery, which remains a technical challenge for surgeons. Our technique for MAC is characterized as simple supra-mitral annular prosthesis insertion after minimum debridement of calcification ("half-and-half technique"). To date, our technique has been applied in only simple MAC cases and has good results. Herein, we report successful two cases of total circumferential MAC, extending into the intervalvular fibrous body and aortic annulus that were treated by a simple double valve replacement with application of our "half-and-half technique".
