ABSTRACT

We present the immediate results of mitral valvuloplasty in 10 patients using Nucleus balloon. Several publications show highly successful results obtained with the Inoue balloon and double balloon technique. There are no publications of Nucleus balloon. We consider that this device could offer several advantages according to its physical and technical characteristics. We performed the procedure in 10 female patients, with severe mitral valve stenosis, with an average age of 44.8 years (23-70) and an average Wilkins score of 7.5 (6-9), using a combined technique. The increase in mitral valve area with Gorlin equation was 1.03 ± .13 to 2.6 ± .67 cm2, the decrease in transmitral gradient from 15 ± 4.1 to 3.42 ± 2.6 mm Hg, and decrease in systolic pulmonary pressure from 54.1 ± 18.8 to 24.9 ± 5.1 mm Hg. One patient developed grade I mitral insufficiency after the procedure, and another non significant interatrial shunt. Conclusions. Good results are obtained with this balloon, the valvuloplasty technique is more simple than with double balloon, it is much cheaper than Inoue balloon and we consider it could be useful in moderately calcified valves.
