We analyzed the results of mitral valve repair in 81 consecutive patients with severe mitral regurgitation. Of these patients, 66.6% had myxomatous degeneration, 11% ischemic disease, 8% chordal rupture, 5% congenital disease, and 3.7% endocarditis. Repair could not be achieved in five patients, and valve replacement was necessary. ⋯ During follow-up (mean 30 [8] months), there was one death due to refractory ischemic heart failure and mitral regurgitation (>or= 2/4) was observed in 11 patients. A good result (i.e., survival without a prosthesis, major complications, or mitral regurgitation >1/4) was obtained in 78% of patients with myxomatous degeneration versus 48% of those with other etiologies (P=.023). A good result was obtained more frequently in cases of isolated posterior cusp degeneration than in those involving degeneration of both cusps (85% vs 70%; P=.03).

Comparative Study
[The implantable cardioverter-defibrillator and hypertrophic cardiomyopathy. Experience at three centers].
Although implantable cardioverter-defibrillators (ICDs) are recommended for high-risk patients with hypertrophic cardiomyopathy (HCM), there is no agreement on their general use. Moreover, little information is available on ICD use in this setting in Spain. Our aims were to describe the characteristics of HCM patients who received ICDs at three hospitals in Spain, and to study indications for device implantation and the results of follow-up in device users. ⋯ The percentage of HCM patients undergoing ICD implantation at Spanish hospitals was highly variable, possibly due to different selection criteria. When used as secondary prevention, ICD therapy was administered appropriately in a high proportion of cases (50% in 3 years).

As patients who are Jehovah's Witnesses are against blood transfusion, they are difficult to manage when a cardiac intervention is required. Between 1998 and 2004, all Jehovah's Witness patients with an indication for cardiac surgery (n=10) were operated on by the same multidisciplinary team. The mean fall in hematocrit was 30% during cardiopulmonary bypass, 35% during the postoperative period, and 22% at discharge. ⋯ All patients survived operation and were discharged. At follow-up, 1 patient died due to respiratory failure. Technological developments that reduce bleeding and enable lost blood to be recovered have made it possible to perform operations involving a risk of hemorrhage in Jehovah's Witnesses.
