Ross-Konno operation for patients with Shone complex.

We report the cases of 2 pediatric patients who had Shone complex. Each child had severe left ventricular outflow tract obstruction and marginal mitral obstruction, and both underwent the Ross-Konno operation. The mitral valve was left alone. Both patients survived the operations, and serial follow-up echocardiography up to 4 years later showed a decreased or decreasing trend in the peak mitral diastolic velocity. The Ross-Konno procedure can be an acceptable approach for a subgroup of patients who have Shone complex.
