[Percutaneous tricuspid valvuloplasty].
The authors herein describe the case of a 44 year old woman, who 14 years ago underwent surgical intervention after a rheumatic disease. A double mitral-aortic valvular implantation and a tricuspid commissurotomy was carried out. The patient come under our observation for severe congestive heart failure, while both mechanical prostheses were working well. Furthermore, the Doppler echocardiography showed a severe tricuspid stenosis (mean gradient = 8.6 mm Hg) and a concurrent mild to moderate valvular regurgitation. Because of her poor clinical condition and due to the high surgical risk it was decided to perform a balloon valvuloplasty of the tricuspid stenosis. The procedure, using the percutaneous femoral approach, was carried out with a TRIAD-TWIN AT (diameter = 18 + 18 mm; length = 4 cm; Mansfield) catheter and an Amplatz guide wire was advanced up to the apex of the right ventricle. Both balloons were inflated simultaneously on three occasions to a maximum pressure of 3.5 atmospheres for 60". At the end of the procedure there was the complete disappearance of telediastolic gradient, the valvular regurgitation remained unchanged (when compared to the pre-valvuloplasty control) and the mean trans-tricuspid gradient reduced to 4 mm Hg. Immediately following the procedure there was a remarkable, rapid hemodynamic improvement of the patient and at three months her condition is constant. In conclusion tricuspid valvuloplasty even using the percutaneous femoral approach can be performed and considered a simple and effective treatment.
