[Serial Doppler echocardiography follow-up studies in the postoperative evaluation of severe pulmonary hypertension following surgery for mitral and mitral-aortic defects].
Between January 1987 and December 1991 26 patients with mitral and mitro-aortic disease and severe pulmonary hypertension (> or = 60 mmHg) were subjected to surgery. In 22 patients we have studied systolic pulmonary pressures by echocardiography-Doppler examination at 3-6 and 12 months from surgery. We noticed a decrease in pulmonary pressure values in all patients within 3 months from surgery (mean values pre-op 75 +/- 12.14; mean values post-op 42 +/- 11.26); within 6 months from surgery physiological values were reached in all patients (mean values 35 +/- 5.3). We have further divided patients in two subgroups: group A with pulmonary pressures superior or equal to 80 mmHg (mean values 90.00 +/- 17.32) and group B With pressure values between 60 and 79 mmHg (mean values 69.12 +/- 3.64). The first Doppler evaluation demonstrated a greater decrease in group B (mean values 37.8 +/- 6.5 versus 57 +/- 12.4); at the second control there was no statistically significant difference between the two groups (group A 36 +/- 5.48, group B 33.33 +/- 5.37). The only two operative deaths were caused by the pre-op cardiogenic shock. There has been no late mortality among survivors, 22 in NYHA Class I and 2 in NYHA Class II. Pulmonary hypertension decreases after surgery independently of the adopted procedure (replacement, repair or lysis).
