[Traumatic tricuspid insufficiency. 5 cases].
Five men (mean age 39 years) were followed up for 6 to 60 months for tricuspid valve regurgitation caused by a front-to-back injury (in a car in four cases, in an aircraft in one case). The time elapsed between the accident and the signal symptoms varied from 28 days to 20 years. The condition was diagnosed on clinical data (stage 2) and on the results of echocardiography and cardiac catheterization. Four patients were operated upon and provided with a bioprosthetic valve. The post-operative period was marked by resolutive atrioventricular block in one case and inferior myocardial infarction in one case. Four points ought to be highlighted: 1. The long-term development of dilatation of the annulus, cicatricial fibrosis or altered left ventricular contractility; 2. The usefulness of pulsed Doppler echocardiography for the diagnosis and surgical indications (quantification of the regurgitation, right ventricular kinetics); 3. The adaptation of treatment to the lesion: repair whenever possible, or annuloplasty, or bioprosthetic valve replacement (mechanical valves must be excluded); 4. The time for surgery is difficult to determine in view of the asymptomatic period, which may be very long. The decision to operate is based on clinical, echocardiographic, haemodynamic and dromotropic (complete arrhythmia due to atrial fibrillation) data. This decision must be reached before right ventricular myocardial deterioration sets in.
