Insights
Surgical repair of Ebstein's anomaly using tricuspid valvuloplasty, particularly the single-stitch technique, offers excellent long-term outcomes. This approach significantly improves patient functional status and clinical well-being.
Area of Science:
- Cardiology
- Cardiac Surgery
- Congenital Heart Disease
Background:
- Ebstein's anomaly is a complex congenital heart defect affecting the tricuspid valve.
- Previous surgical interventions, including valve replacement, have shown suboptimal results.
- Current surgical focus is on tricuspid valvuloplasty techniques.
Purpose of the Study:
- To evaluate the long-term efficacy and outcomes of tricuspid valvuloplasty in patients with Ebstein's anomaly.
- To assess the functional improvement and survival rates following surgical repair.
- To compare the results of valvuloplasty with historical valve replacement data.
Main Methods:
- A cohort of 60 patients with Ebstein's anomaly underwent surgical repair between 1974 and 1995.
- Tricuspid valvuloplasty, primarily using the single-stitch technique, was performed in 56 patients (93.3%).
- Four patients (6.7%) underwent tricuspid valve replacement with a bioprosthesis; six reoperations were required.
Main Results:
- Hospital mortality was 3.3% (2 patients), with a late mortality rate of 10.0% (6 patients).
- Actuarial survival at 18 years was 83.3% +/- 5.6%.
- Follow-up in 52 survivors (median 5.0 years) showed 93.9% in functional class I or II, with good tricuspid valve function on Doppler echocardiography.
Conclusions:
- Tricuspid valvuloplasty, especially with the single-stitch technique, is a highly effective surgical option for Ebstein's anomaly.
- The procedure leads to significant and durable improvements in patient functional capacity and overall clinical status.
- Valvuloplasty represents a rewarding surgical approach with favorable long-term results.
Background:
Ebstein's anomaly of the tricuspid valve is a complex malformation. Various operations have been undertaken with varying results. Because valve replacement yielded poor results, surgical treatment has focused on valvuloplasties.
Methods:
Between April 1974 and February 1995, 60 patients with Ebstein's anomaly underwent surgical repair. Age ranged from 5 months to 54 years. In 56 patients (93.3%), tricuspid valvuloplasty was feasible, mainly by creating a monocusp valve with the single-stitch technique. The other 4 patients had valve replacement with a bioprosthesis. Six reoperations were necessary (10.0%): four valve replacements and two repeat valvuloplasties.
Results:
There were two hospital deaths (3.3%) and a late mortality rate of 10.0% (6 patients). Forty-nine (94.2%) of 52 survivors were followed for 5 months to 18.6 years (median follow-up, 5.0 years; mean follow-up, 6.9 years). The actuarial survival rate (Kaplan-Meier) was 96.5% +/- 2.4% at 1 year and 83.3% +/- 5.6% at 18 years. At follow-up evaluation, nearly all patients showed substantial improvement (93.9% were in functional class I or II) compared with their preoperative status. Doppler echocardiographic studies demonstrated good tricuspid valve function in most patients.
Conclusions:
Valvuloplasty using the single-stitch technique is a rewarding operation. It yields good long-term results with substantial improvement in functional performance and clinical status.
