| Abstract: | PURPOSE: To compare immediate and long term results balloon mitral valvuloplasty (BMV) using double balloon or bifoil balloon. METHODS: One hundred and thirteen consecutive cases of BMV used aleatory double balloon (group DB--55 cases) or bifoil balloon (group BF--16 cases). Patients were similar regarding to age, sex, valvopaty etiology, functional class and echocardiographic score. Seventy one (63%) patients achieved 12 months follow-up. RESULTS: In group DB there were 2 (4%) insuccess, 2 (4%) cardiac tamponade and 2 (4%) deaths, 91% patients had immediate criteria of success. Mitral valve area (MVA) increased from 0.8 to 1.69cm2 and mitral gradient (G) by echodopplercardiographic (ECHO) decreased from 17.9 to 4.8mmHg. Three (5%) patients developed severe mitral regurgitation (MR) and needed surgical intervention. At follow-up 2 (4%) developed mitral restenosis. MVA estimated by ECHO study after one year follow-up was inferior to 1.15cm2 in 15 (32%) cases, between 1.5 and 2.0cm2 in 17 (37%) and superior to 2.0cm2 in 14 (31%). In group BF there were 2 (12.5%) insuccess, 4 (25%) developed severe MR occurring 1 death immediate post-operative mitral valve replacement. Among 14 (87%) success cases, MVA increased from 0.8 to 1.89cm2 and G decreased from 18 to 6.4mmHg. Lately 2 (12.5%) needed surgical intervention because significative MR. At 12th month follow-up the ECHO study showed that in one (10%) case MVA was < 1.5cm2, and in 3 (27%) cases was between 1.5 and 2.0cm2. CONCLUSION: There were similar good results in both groups, however group DB had more restenosis, cardiac tamponade and vascular complications and group BF had more severe MR. |
