ABSTRACT
OBJECTIVES: To analyze immediate and long-term results of balloon dilation for aortic coarctation in a three-center experience in Mexico, and to determine factors associated with increased risk. BACKGROUND: Results demonstrated that the procedure is effective and safe, however its use in some groups is still controversial, specially in neonates and infants. METHODS: In a ten-year period, 333 patients with aortic coarctation on underwent balloon dilation with an immediate success rate of 93.7% and a major complication incidence of 1.8%. Of the total cohort, 272 patients were followed for a period of 24.3 +/- 20 months. Demographic and procedural data were analyzed to determine factors related to a poor outcome or to sustained high blood pressure. RESULTS: Cox regression analysis found age (risk ratio 3.42 p = 0.0001), isthmic hypoplasia (risk ratio 4.64, p < 0.0001), and post-dilation gradient (risk ratio 2.19, p = 0.0113) as independent risk factors for a follow-up event, mainly restenosis. Age at dilation was the only independent factor related to sustained hypertension with a seven-fold increase in the risk. CONCLUSIONS: Balloon dilation is an effective and safe alternative to treat aortic coarctation. Patients younger than one year of age, with severe isthmic hypoplasia and a post-dilation gradient > 20 mmHg have the highest risk to develop an event in the follow-up period. When the dilation procedure is performed in patients older than 10 years of age, and specially those older than 20 years, the probability that they remain or develop high blood pressure is increase.

Se presentan cinco casos de cor triatriatum correspondientes a sujetos con edad promedio de 3.6 años (límites: 11 meses y 10 años), que fueron manejados durante un periodo de menos de 2 años, y se hace una revisión de la literatura. Tres pacientes fueron operados con resultados satisfactorios, otro enfermo falleció después del cateterismo cardiaco por edema pulmonar agudo y el último, con una obstrucción poco significativa, está en espera del tratamiento quirúrgico. Se hace énfasis en la utilidad del eco Doppler color para establecer el diagnóstico de esta cardiopatía congénita. No tenemos una explicación completa para la frecuencia del tal cardiopatía en un lapso tan corto

Se presentan dos casos de enfermedad de Kawasaki con aneurismas coronarios diagnosticados por ecocardiografía. El primer paciente de un año de edad, con afección del tronco de la coronaria izquierda, desarrolló infarto del miocardio y falleció tres semanas después de la detección de los aneurismas. El segundo de 2 meses, con afección de la coronaria derecha, se encuentra asintomático a tres meses del diagnóstico. Se hace énfasis en la utilidad de la ecocardiografía para el diagnóstico de las complicaciones cardíacas
