[Long-term results of percutaneous mitral valvuloplasty in patients over 50 years old]. / Resultados de valvuloplastía mitral percutánea en pacientes mayores de 50 años y seguimiento a largo plazo.

UNLABELLED: Advanced age has been identified as a predictor factor for complications and poor outcome at Percutaneous Mitral Valvulotomy (PMV) with balloon, nevertheless this has been associated to the inadequate valvular anatomy, whereby the contribution of each factor needs to be determinate. OBJECTIVE: Describe the immediate and final outcome of PMV with Inoue balloon in patients over 50 years old and associate complications with age and Wilkins score. MATERIAL AND METHODS: A retrospective and analytic study was performed with a data base of 430 patients. We included all the patients proceeding from the Centro Medico Nacional Siglo XXI Cardiology Hospital. From January 1996 to December 2005. RESULTS: We selected 137 patients with rheumatic mitral stenosis. We found a Mitral Valvular Area (MVA) before the PMV proceeding of 1.01 cm2 +/- 0.18 and 1.99 cm2 +/- 0.30 post PMV (P < 0.001), with pre procedure transmitral gradient of 14.3 +/- 3.18 mm Hg and of 4.3 +/- 2.6 mm Hg post (P < 0.001). In 128 (93%) the immediate proceeding was considered successful. The Wilkins score was 8.41 +/- 1.31. The observed complications were present in 19 (13.8%), stroke in 3 (2.2%), tamponade in 3 (2.2%), conduction disorder in 5 (3.7%), severe mitral insufficiency in 7 (5.1%), residual interatrial communication in 1 (0.7%). A clinical and echocardiographic follow-up was performed in 113 (83%) MVA was > 1.5 cm2 in 113 at 70 [IBM1] months average, 1.1 to 1.49 cm2 in 14 (10.2%) and < 1 cm2 in 9 (7%). CONCLUSIONS: PMV with Inoue balloon in patients over 50 years old is a procedure with an immediate high successful index and of acceptable risk. We found a restenosis index of 27 (19%) after long follow-up 70 months average.

[Immediate and long-term results of implantation of the new platinum coronary stent (atlas stent) in patients with coronary artery disease]. / Resultados inmediatos y a largo plazo del implante de un nuevo stent coronario de platino (stent Atlas) en pacientes con enfermedad arterial coronaria.

BACKGROUND AND OBJECTIVES: We evaluated the technical and clinical results of implantation of the Atlas stent, the hospital stay, and the short and long-term clinical and angiographic outcome. PATIENTS AND METHOD: The study included 169 patients (60.1 10.8 year-old), 60.3% of which had acute coronary syndromes and complex lesions. Immediate success was achieved in 98% of cases. The clinical follow-up in 85.7% of the patients at 14.3 6.8 months, revealed that 89% remained free of adverse events and most (94.4%) were functional class I of the CCS. Angiographic follow-up at 8.4 4.1 months of 40.9% of the cases revealed restenosis in 27.9%. There were 2 cases of subacute thrombosis. CONCLUSIONS: The application of the Atlas stent in patients with a diverse clinical spectrum demonstrated good immediate and long term results, with a rate of restenosis similar to that of other stents available on the market.

Introducción y objetivos. Evaluamos el resultado técnico y clínico de la aplicación del stent coronario de platino, la evolución hospitalaria, así como la evolución clínica y angiográfica, tanto a corto como a largo plazo. Pacientes y método. Incluimos a 169 pacientes consecutivos de 60,1 +/- 10,8 años, en su mayoría (60,3 por ciento) con síndromes isquémicos agudos y lesiones complejas. Se obtuvo éxito inmediato en el 98 por ciento de los casos. El seguimiento clínico en el 85,7 de los pacientes a los 14,3 +/- 6,8 meses reveló qu el 89 por ciento se mantuvo libre de acontecimientos adversos y la mayoría (94,4 por ciento) en clase funcional I. El seguimiento angiográfico a los 8,4 +/- 4,1 meses en 40,9 por ciento de los casos puso de manifiesto reestenosis en el 27,9 por ciento. Hubo 2 casos de trombosis subaguda. Conclusiones. La aplicación del sten Atlas TM en pacientes con espectro clínico diverso demostró buenos resultados inmediatos y tras el seguimiento, con tasas de reestenosis similares a las obtenidas con otros stents disponibles en el mercado (AU)

[Stenting and redilatation of the ductus arteriosus in univentricular heart with pulmonary atresia. A case report]. / Stent y redilatación con globo del conducto arterioso en ventrículo único con atresia pulmonar. Descripción de un caso.

Complex congenital heart disease with pulmonary atresia is ductus arteriosus-dependent. Two palliative treatments have been available for years: a systemic pulmonary shunt and prostaglandin E1 infusion. Recently, interventional cardiology has offered a new procedure for these patients: stenting of the patent arterial duct. We report a case with univentricular heart and pulmonary atresia in which percutaneous balloon angioplasty and stenting of the arterial ductus were performed successfully. Nineteen months later the patient is in good clinical conditions with 75% of oxygen saturation.
