Palliative arterial switch as first-line treatment before the fontan procedure in patients with single-ventricle physiology and subaortic stenosis.

Introduction And Objectives: There are several techniques for the palliative treatment of patients with single-ventricle physiology, ventriculoarterial discordance and subaortic stenosis. The Fontan procedure relies on optimal initial palliation to avoid the development of subaortic stenosis (as well as ventricular hypertrophy and diastolic dysfunction).

Methods: We present seven patients with single-ventricle physiology, transposition of the great arteries and subaortic stenosis, with low systemic output and high pulmonary flow, aged 21 to 383 days (median, 75) and weighing between 3.

Minimally invasive pediatric cardiac surgery. Atrial septal defect closure through axillary and submammary approaches.

Introduction And Objectives: Minimally invasive approaches in less-complex cardiac procedures can avoid unpleasant cosmetic results. Moreover, surgery can be scheduled in younger patients. In previous papers, we compared submammary and midline sternotomy.

Use of a pulmonary neovalve with a transannular patch for repair of tetralogy of fallot.

Introduction And Objectives: To report on our initial experience with the implantation of a pulmonary valve using Nunn's technique in association with a transannular patch for the complete repair of the tetralogy of Fallot.

Methods: In total, 21 patients were treated between September 2008 and February 2010. Their ages ranged from 7 months to 15 years (median 12 months) and weights from 6.
