Abstract

Two kinds of monocusp patch were used for reconstruction of right ventricular outflow tract in patients with a variety of congenital heart defects. A bovine pericardial patch with monocusp (MVOP) was used in 11 patients (group M), and a separate transannular outflow patch (STOP) with turned-down equine pericardial monocusp was used in 10 patients (group S). Mean age at operation was 9 years 5 months in group M, and 7 years 9 months in group S. There was one operative death in group M. Survivors have completed a mean follow-up of 19 months. There were no late deaths. In early postoperative period, mean peak systolic pressure gradient between right ventricle and main pulmonary artery was 21 +/- 11 mmHg in group M and 21 +/- 11 mmHg in group S, which were not statistically significant. During follow-up period, no significant increase of peak systolic pressure gradient was noted in both groups. In late postoperative period, pulmonary regurgitation was moderate in 7 and severe in 1 in group M, while it was non-significant in 1, mild in 6 and moderate in 2 in group S. The difference between two groups was significant (p < 0.005). In conclusion, both types of patches equally relieved right ventricular outflow obstruction, but STOP prevented postoperative pulmonary regurgitation more effectively.

[Evaluation of the growth of a new pulmonary trunk after the reconstruction of right ventricular outflow tract without using an external conduit].

To evaluate the growth of a pulmonary trunk reconstructed without an extracardiac conduit, the hemodynamics and diameter of a new pulmonary trunk were measured in 5 patients from the right ventriculogram and MRI at postoperative follow-up periods. There were tetralogy of Fallot with pulmonary atresia in two patients, tetralogy of Fallot with single coronary in one, truncus arteriosus type I in one and transposition of the great arteries with ventricular septal defect and pulmonary stenosis in one. The age at operation ranged from 26 days to 4.5 years. The posterior wall continuity of the right ventricle and pulmonary artery was established by the direct pulmonary-right ventricular anastomosis in three patients and by the interposition of the left atrial appendage in two. Postoperative follow-up periods ranged from 2 years and 6 months to 3 years and 10 months (median: 2 years and 11 months). In four of them, the postoperative right ventricular to aortic or left ventricular systolic pressure ratios were less than 0.4 without any significant systolic pressure gradients between pulmonary artery and right ventricle. In these four patients, the diameters of the reconstructed pulmonary trunks grew from 10-18 mm to 18-21 mm postoperatively. These diameters were more than 100% of normal values. In the remaining patient with tetralogy of Fallot and single coronary artery, the obstruction of the new pulmonary trunk by a bulged left atrial appendage, which was used as the posterior wall, was observed on the right ventricular outflow tract reconstruction without an extracardiac conduit has growth potential in the future.

Tricuspid valve replacement: UK Heart Valve Registry mid-term results comparing mechanical and biological prostheses.

BACKGROUND: Little is known of time-related outcome and comparative performance of biological and mechanical prostheses following tricuspid valve replacement (TVR). METHODS: A retrospective UK Heart Valve Registry study (Jan 1, 1986 to June 30, 1997) identified 425 patients who underwent TVR. Two-hundred twenty-five (52.9%) received biological and 200 (47.1%) received mechanical valves. One-hundred sixty (38%), 158, and 76 had isolated, double, and triple valve replacements, respectively. The follow-up was 96% complete with a total of 1,585 patient-years. RESULTS: Thirty-day mortality for TVR was 17.3% (73 deaths). One-, 5-, and 10-year survival rates were 72.2%, 59.9%, and 42.9%, respectively. Year of operation (p = 0.04), age (p = 0.04), and number of valves implanted (p = 0.0 3) predicted overall mortality. Age (p<0.001) and year of operation (p = 0.002) predicted overall survival. Thirty-day mortality for biological and mechanical prostheses was 18.8% and 15.6%, respectively. One-, 5-, and 10-year survival rates were 70.5%, 61.5%, and 47.7% for biological and 74.0%, 57.9%, and 33.9% for mechanical prostheses, respectively. Freedom from reoperation at 1 and 10 years was 98.7% and 97.4%. Freedom from death or reoperation was 71.2% at 1 year and 41.9% at 10 years. None of the above outcomes was significantly different between the type of valve prostheses. CONCLUSIONS: TVR carries a high 30-day mortality and a poor longer term survival. No superiority could be identified for biological or mechanical prostheses in the tricuspid position for either survival or reoperation.
