Tricuspid regurgitation (TR) in patients with rheumatic heart disease is associated with poor outcome and predicts poor survival, heart failure, and reduced functional capacity.
The objective of this study is to review our surgical outcomes with tricuspid De Vega annuloplasty’s for functional tricuspid regurgitation in rheumatic heart disease.
Patients and Methods
Number of Patients: 520
Age : 37 ( 18 – 67 Y)
Gender (Male/Female): F: 52% M: 48%
II : 78 paients (15% )
III: 296 patients (57%)
VI: 146 patients (28%)
Valve surgery: Numbre of patients
MVR 306 ( 59%)
MVP 43 ( 8%)
MVR and AVR 150 ( 29%)
MVP and AVR 21 (4%)
MVR : mitral valve replacement, MVP : mitral valve plasty, AVR : aortic valve replacement
De Vega annuloplasty:
- Annuular size per tricuspid annuloplasty: Tightening over 2 fingers of the surgeon
- The tricuspid competence was checked with saline test : all patients
Result (1): Early post-operative
Operative mortality : 23 ( 4,4%)
complications of annuloplasty De Vega:
- Right sided Heart failure 1 to 2 weeks after De Vega annuloplasty: 7(1,4%) patients (with severe pulmonary hypertension and or right ventricular dysfunction).
-Tricuspide stenosis: 4 patients (0,7%)
Dyspnea NYHA Class improvement: grade III- IV to grade I and II in 85,5% patients.
Post-operative echo study:
- Midl or less TR: 453 patients (87%)
Moderate TR : 37 patients (7%)
Severe TR: 7 patients (1.34%)
- Pylmonary hypertention : 47 (35- 85mmhg)
Result (3): Follow up: 5 years after surgery
Late mortality: 17 patients (3.2%):
- Lower LVFE: 3 P
- Heart failure with severe TR: 3 P
- Prosthetic valve endocarditis: 2 P
- Anticoagulation-related hemorrhage: 6 P
- Thromboembolism of Prosthetic valve: 1 P
- Sudden death (unexplained): 2 P
NYHA Status for surviving patients: 320 patients
- I - II : 295 Patients (92% )
- III : 16 Patients (5 %)
- VI : 10 Patients (3 %)
De Vega annuloplasty: is a simple, short, and inexpensive procedure with few complications.
Preoperative Pylmonary hypertention is one of risk factors to attribute to recurrent TR.
In a developing country like Morocco, De Vega annuloplasty remains the procedure of choice in the management of functional tricuspid valve incompetence.
