“…The imp lan tation of a prosthet ic car diac valve with a large enough diame te r in th e aortic position not seldom fails because of too small an aortic annulus, especiall y in pat ients with aortic valve stenosis. On these grounds variou s operative procedures have been devel oped for the enlargement of the left ventricular o utflo w tract (3 -5, 9, 15, 16, 20, 26, 32), inclu ding the incorporation of a graft in the aortic incision whi ch has been ex tended through the valve annulus as far as th e ante rio r mitral valve leaflet (3,5,14,16), 3 1). This procedure , recommended by N icks and co-worke rs (20) in 1970, clinically tested by Borst and co-workers in 1973 (3,5,12,13), and finally developed furt her by Manouguian in 1976 (16), has been routinely used in patients with small aortic root s in our clinic sinc e au tumn Received fo r Publi cati on : March 25, 1985 1976 (5,12,13).…”

From 1976 to 1984, 31 patients underwent enlargement of very small aortic roots using autologous pericardial strips the subannular part of which extended into the incised anterior mitral valve leaflet. The majority of these interventions (n = 24) were carried out before the end of 1980. Over an average follow-up period of 52.5 months, only one of the surviving patients had a complication traceable to the pericardial implantation (aneurysmatic patch dilatation), and 2 late deaths were also not directly connected with the type of surgical procedure. Objective findings for evaluating the hemodynamic status and behavior of the patch material were attained in a total of 14 patients by heart catheterization and angiography. Eleven patients were examined twice at an average of 2.5 months, and 11 at an average of 52.5 months. Eight of latter patients had undergone an early postoperative investigation. The hemodynamic results after prosthetic valve replacement and aortic annulus enlargement was satisfactory in those examined. No evidence could be found in any patient of disturbance of the mitral valve's function, paravalvular leakage at the aortic prosthesis, or obstruction of the left ventricular outflow tract caused by this operative technique. Progressive patch dilatation which had already been proved at the first examination was observed in one case. These results verify not only the efficiency of this technique for the enlargement of a small aortic root in the frame of prosthetic valve replacement, but especially the suitability of autologous pericardium as patch material for this purpose.

“…When the AMC is involved in pathological processes, the “Commando” [ 1 , 2 ] (also called “UFO” procedure [ 3 ]) is performed ( Supplementary File , Surgery). It was firstly described in 1976 [ 4 ]. This technique consists of aortic and mitral valve replacement and Left Ventricular Outflow Tract (LVOT) reconstruction with autologous or allograft pericardium.…”

The Commando procedure is challenging, and aims to replace the mitral valve, the aortic valve and the aortic mitral curtain, when the latter is severely affected by pathological processes (such as infective endocarditis or massive calcification). Given the high complexity, it is seldomly performed. We aim to review the literature on early (hospitalization and up to 30 days) and long-term (at least 3 years of follow-up) results. Bibliographical research was performed on PubMed and Cochrane with a dedicated string. Papers regarding double valve replacement or repair in the context of aortic mitral curtain disease were included. The metaprop function was used to assess early survival and complications (pacemaker implantation, stroke and bleeding). Nine papers (540 patients, median follow-up 41 (IQR 24.5–51.5) months) were included in the study. Pooled proportion of early mortality, stroke, pacemaker implant and REDO for bleeding were, respectively 16.2%, 7.8%, 25.1% and 13.1%. The long-term survival rate ranged from 50% to 92.2%. Freedom from re-intervention was as high as 90.9% when the endocarditis was not the first etiology and 78.6% in case of valvular infection (one author had 100%). Freedom from IE recurrences reached 85% at 10 years. Despite the high mortality, the rates of re-intervention and infective endocarditis recurrences following the Commando procedure are satisfactory and confirm the need for an aggressive strategy to improve long-term outcomes.

An anatomical study of a new method for enlargement of narrowed aortic annulus: Intra-arterial aorto-infundibuloplasty

A new procedure "intraarterial aorto-infundibuloplasty" for the narrowed aortic annulus is described. Aortic valve replacement is performed through an aorto-pulmonary and infundibular septal incision which is eventually enlarged by a single patch, i.e., a two-dimensional patch instead of a three-dimensional patch as in Konno's procedure. An anatomical study showed that a prosthetic valve three sizes larger than the natural annular diameter could be implanted and the natural annular diameter was increased by as much as 42%.
