Criss-cross con discordancia auriculoventricular, acabalgamiento de la válvula auriculoventricular derecha, doble salida del ventrículo derecho y preexcitación

Successful catheter ablation using real-time ultrasound-assisted 3-D electroanatomical mapping system for atrioventricular accessory pathway in a 1-year-old girl with criss-cross heart

“…The second case was a newborn with cyanosis, dyspnea, and supraventricular tachycardia because of reentry who died suddenly after 6 days of follow-up. Necropsy confirmed the diagnosis of criss-cross heart with AV discordance, straddling right AV valve, double-outlet right ventricle, and ventricular pre-excitation 7 .
