Percutaneous mitral valvuloplasty in patients with low cardiac output at high surgical risk.
Among 1146 patients undergoing percutaneous mitral valvuloplasty for symptomatic mitral stenosis, 8 (4 men and women) were at high risk for surgery on the basis of the New York Heart Association functional class IV (n=8), severe pulmonary hypertension (n=5). All these patients aged 30+/-23.6 years had signs of right heart failure, high echocardiographic score (9.6+/-3.6) and low mitral valve area (0.50+/-0.19 cm(2)). The procedure resulted in an increase in mitral valve area (1.55+/-0.17 cm(2)) with a concomitant reduction in pulmonary artery systolic pressure (58.7+/-9.9 mm Hg) and decrease in tricuspid regurgitation. At follow-up (mean 14+/-3 months), one patient with renal failure... presented with a mitral restenosis is scheduled for mitral valve replacement, two patients with severe tricuspid regurgitation required tricuspid annuloplasty. In conclusion, percutaneous mitral valvuloplasty is feasible and safe in patients at high surgical risk and can be considered as an acceptable alternative to surgery.
