Abstract (English): Introduction: 1 in 40 000 to 100 000 births represents the incidence of cojoined twins and only 1 in 200 000 live births. They also tend to be more frequent in females (3: 1). Cardiac malformations represent almost half of malformations at birth, meaning that 0.8% of live births have some congenital heart disease. Materials and methods: The ablation of both cardiopulmonary blocks of the cojoined twins was performed and the mediastinum were dissected. Results: In the pathological anatomy the cojoined twins shared lower limbs, pelvis, abdomen and a common thoracic cavity, without fusion of any intrathoracic organ. One of the twins presented a normal heart, the other, multiple cardiovascular malformations. When the heart was opened, the heterotaxia of the heart was confirmed by: complete atrioventricular canal, complete transposition of the great vessels, hypoplasia of the right pulmonary artery and lusoria subclavian artery, associated with agenesis of the inferior vena cava, persistent superior left vena cava and a single pulmonary vein.

Abstract (Spanish): Introducción: 1 de cada 40 000 a 100 000 partos representa la incidencia de gemelos unidos y solamente 1 de cada 200 000 nacidos vivos. También suelen ser más frecuentes del sexo femenino (3:1). Las malformaciones cardíacas representan casi la mitad de malformaciones al nacer, es decir que el 0,8% de los nacidos vivos presenta alguna cardiopatía congénita. Materiales y métodos: Se procede a la ablación de ambos blocks cardiopulmonares de los gemelos toracodimos y se disecaron los mediastinos. Resultados: En la anatomía patológica los gemelos unidos compartían miembros inferiores, pelvis, abdomen y una cavidad torácica común, sin fusión de ningún órgano intratorácico. Uno de los gemelos presentaba un corazón normal, el otro, múltiples malformaciones cardiovasculares. Al realizar la apertura del corazón se constató la heterotaxia del mismo constituida por: canal aurículo ventricular completo, transposición completa de los grandes vasos, hipoplasia de la arteria pulmonar derecha y subclavia lusoria, asociada a agenesia de vena cava inferior, vena cava superior izquierda persistente y vena pulmonar única.
