Resumen
Introducción: la anomalía de Ebstein es una cardiopatía congénita compleja infrecuente, descrita por primera vez en 1866 por el médico Wilhelm Ebstein, caracterizada por malformaciones anatómicas y funcionales de la válvula tricúspide y del ventrículo derecho a consecuencia de una inadecuada deslaminización del tejido valvular tricuspídeo. Mediante la presentación de caso clínico y revisión de la literatura analizamos el abordaje de un paciente adulto con anomalía de Ebstein con preexcitación ventricular.
Caso clínico: describimos el caso de un paciente masculino de 34 años, con historial clínico de palpitaciones y disnea, en sus paraclínicos se documentó anomalía de Ebstein tipo B asociado a foramen oval permeable y taquicardia paroxística supraventricular, como tratamiento se realizó ablación por radiofrecuencia exitosa y proponiéndose valvuloplastia tricuspídea.
Conclusión: la anomalía de Ebstein es compleja de espectro clínico, morfológico y fisiopatológico heterogéneo, manifestada desde formas graves sintomáticas en el periodo neonatal hasta asintomáticas o mininamente sintomáticas detectadas de forma incidental. Su diagnóstico parte de la sospecha clínica confirmándose a partir de ecocardiografía o estudios de imagen. La estrategia terapéutica puede estar basada en manejo médico en sus formas leves asintomáticas hasta intervenciones quirúrgicas que incluyen valvulo-plastia tricuspídea, cirugía paliativa, reemplazo valvular o trasplante cardiaco.
Abstract
Background: Ebstein’s anomaly is a rare complex congenital heart disease, first described in 1866 by physician Wilhelm Ebstein, characterized by anatomical and functional malformations of the tricuspid valve and the right ventricle because of inadequate delaminization of the tricuspid valve tissue. By presenting a clinical case and reviewing the literature, we analyzed the approach of an adult patient with Ebstein anomaly with ventricular preexcitation.
Clinical case: We describe the case of a 34-year-old male patient, with a clinical history of palpitations and dyspnea, and his paraclinics documented Ebstein type B anomaly associated with patent foramen oval and paroxysmal supraventricular tachycardia, Successful radiofrequency ablation was performed and tricuspid valvuloplasty was proposed.
Conclusion: It is concluded that Ebstein’s anomaly is complex with clinical, morphological and physiopathological heterogeneous spectrum. Manifested from severe symptomatic forms in the neonatal period to asymptomatic or minimally symptomatic ones detected incidentally. Its diagnosis is based on clinical suspicion and confirmed by echocardiography or imaging studies. The therapeutic strategy may be based on medical management in its mild asymptomatic forms up to surgical interventions that include tricuspid valvuloplasty, palliative surgery, valve replacement or cardiac transplantation.
