[Pulmonary valve autograft for aortic valvulopathy].

Twelve patients were operated on between February 1992 and June 1993 because aortic valve disease with pulmonary autograft replacement of the aortic valve and reconstruction of the right ventricular outflow tract with a valved tube of autogenous pericardium and bovine prosthetic pericardium valve made at the Instituto Nacional de Cardiología Ignacio Chávez. Aortic and pulmonary annular diameters were taken preoperative in all patients by transthoracic echocardiography. During the surgical procedure, transthoracic echocardiography was done in order to assess valvular function of the pulmonary autograft. There was no peri-operative morbi-mortality and no anticoagulation was required. Post operative evolution was satisfactory in all patients and were discharged after transthoracic echocardiography evaluation. Annular diameters correlated with the trans-surgical annular measurements. We conclude that the use of the pulmonary autograft in selected cases can be done, in order to relieve aortic valve disease, without significant morbi-mortality as compared with single aortic valve replacement.
