Abstract

Since the introduction of the annuloplasty ring, many attempts have been made to obtain a flexible ring that preserves the physiological motion of the mitral annulus. We experimented with a new technique using autologous pericardium to construct a more flexible ring. Twenty patients underwent mitral valve repair for degenerative disease and were treated by a posterior pericardial annuloplasty and the usual valvuloplasty procedures. A long strip of pericardium was prepared, marked with metal clips and rolled up in a tubular fashion with the serosal surface on the outside. The pericardial tube was apposed on the posterior annulus just beyond the commissures. No patient required early or late reoperation. Doppler analysis showed good valve function: 18 patients had no or mild, and 2 had moderate regurgitation. Transmitral flow indexes were nearly normal (MVA =3.7 ±0.4 cm2; flow velocity peak=1.06 ± 0.2 m/s). Fluoroscopic examination was employed for assessing annular motion using the metal clips as radiopaque markers. Planimetry of the hemiarea showed a mild narrowing (mean 8.5% ± 6.4%) of annular size during ventricular systole. There was a trend toward a systolic reduction of the anteroposterior diameter of the annulus. These findings demonstrate that the mitral orifice preserves its flexible properties after this type of annuloplasty. Posterior pericardial annuloplasty seems to be a physiological correction of annular dilatation in patients with degenerative disease. [Eur J Cardio-thorac Surg (1991) 5:226-229].
