Further Outpatient Care

Give careful attention to atrioventricular valve (AVV) function and development of left ventricular (LV) outflow obstruction on follow-up visits if a biventricular repair was accomplished.

If a single-ventricle repair was performed, follow-up care and complications occur as with other patients with a single ventricle. See Single Ventricle for a comprehensive list of postoperative complications and medical management.

Inpatient & Outpatient Medications

If a successful biventricular repair is accomplished, long-term cardiac medications are generally not needed after surgical convalescence.

In patients who underwent single-ventricle palliation, aspirin with or without warfarin (Coumadin) may be used to reduce the risk of thrombus formation within the Fontan circuit. Additionally, an ACE inhibitor may be prescribed to optimize ventricular function or for the treatment of AVV regurgitation. Antiarrhythmic medications are used as indicated for the treatment of specific arrhythmias.
