Tetralogy of Fallot (TOF) is the most common cyanotic heart defect and occurs in 5-10% of all children with congenital heart disease. The classic description of TOF includes four cardiac abnormalities: overriding aorta, right ventricular hypertrophy (RVH), large perimembranous ventricular septal defect (VSD), and right ventricular outflow tract obstruction (RVOTO). About 20% of patients with TOF have PA at the infundibular or valvar level, which results in severe right ventricular outflow tract obstruction. PA means that the pulmonary valve is closed and not developed. When PA occurs, blood can not flow through the pulmonary arteries to the lungs. Instead, the child is dependent on a patent ductus arteriosus (PDA) or multiple systemic collateral vessels (MAPCAs) to deliver blood to the lungs for oxygenation. These MAPCAs usually arise from the de- scending aorta and subclavian arteries. Commonly, the pulmonary arteries are abnormal, with hypoplastic (small and underdeveloped) central and branch pulmonary arteries and/ or non-confluent central pulmonary arteries.

  • Pulmonary Atresia / Intact Ventricular Septum
    Pulmonary Atresia / Intact Ventricular Septum What is it? In pulmonary atresia, no pulmonary valve exists. Blood can’t flow from the right ventricle into the pulmonary artery and on to the lungs. The right ventricle and tricuspid valve are often poorly developed. What causes it? In most children, the cause isn’t known. Some children can have other heart defects along with pulmonary atresia. (Children with tetralogy of Fallot who also have pulmonary atresia may have treatment similar to others with tetralogy of Fallot.) How does it affect the heart? An opening in the atrial septum lets blood exit the right atrium, so low-oxygen (bluish) blood mixes with the oxygen-rich (red) blood in the left atrium. The left ventricle pumps this mixture of oxygen- poor blood into the aorta and out to the body. The infant appears blue (cyanotic) because there’s less oxygen in the blood. The only source of lung blood flow is the patent ductus arteriosus (PDA), an open passageway between the pulmonary artery and the aorta. How does pulmonary atresia affect my child? If the PDA narrows or closes, the lung blood flow is reduced to critically low levels. This can cause very severe cyanosis. Symptoms may develop soon after birth. What can be done about the defect? Temporary treatment includes a drug to keep the PDA from closing. A surgeon can create a shunt between the aorta and the pulmonary artery that may help increase blood flow to the lungs. A more complete repair depends on the size of the pulmonary artery and right ventricle.

  • Early and Intermediate Outcomes After Repair of Pulmonary Atresia With
    Early and Intermediate Outcomes After Repair of Pulmonary Atresia With Ventricular Septal Defect and Major Aortopulmonary Collateral Arteries Experience With 85 Patients V. Mohan Reddy, MD; Doff B. McElhinney, MD; Zahid Amin, MD; Phillip Moore, MD; Andrew J. Parry, MD; David F. Teitel, MD; Frank L. Hanley, MD Background—Pulmonary atresia with ventricular septal defect (VSD) and major aortopulmonary collaterals (MAPCAs) is a complex lesion with marked heterogeneity of pulmonary blood supply. Traditional management has involved staged unifocalization of pulmonary blood supply. Our approach has been to perform early 1-stage complete unifocalization in almost all patients. Methods and Results—Since 1992, 85 patients with pulmonary atresia, VSD, and MAPCAs have undergone unifocal- ization (median age, 7 months). Complete 1-stage unifocalization and intracardiac repair were performed through a Downloaded from midline approach in 56 patients, whereas 23 underwent unifocalization in a single stage with the VSD left open, and 6 underwent staged unifocalization through sequential thoracotomies. There were 9 early deaths. During follow-up (1 to 69 months), there were 7 late deaths. Actuarial survival was 80% at 3 years. Among early survivors, actuarial survival with complete repair was 88% at 2 years. Reintervention on the neo–pulmonary arteries was performed in 24 patients. Conclusions—Early 1-stage complete unifocalization can be performed in Ͼ90% of patients with pulmonary atresia and http://circ.ahajournals.org/ MAPCAs, even those with absent true pulmonary arteries, and yields good functional results. Complete repair during the same operation is achieved in two thirds of patients. There remains room for improvement; actuarial survival 3 years after surgery is 80%, and there is a significant rate of reintervention.

  • Midline Unifocalization for Pulmonary Atresia with Ventricular Septal Defect and Major Aortopulmonary Collateral Arteries
    1273 Original Article on Management of Congenital Heart Disease Midline unifocalization for pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries Richard D. Mainwaring Division of Pediatric Cardiac Surgery, Lucile Packard Children’s Hospital/Stanford University, Stanford, CA, USA Correspondence to: Richard D. Mainwaring, MD. Stanford University School of Medicine, 300 Pasteur Drive, Falk CVRC, Stanford, CA 94305, USA. Email: [email protected]. Background: Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA/VSD/MAPCAs) is a relatively rare and extremely heterogeneous form of congenital heart disease. Despite vast improvements in the surgical management of this disease, there is still an ongoing controversy regarding the optimal treatment. The purpose of this chapter is to summarize the surgical algorithm used at Stanford University with a special focus on midline unifocalization. Methods: We have an experience with well over 300 patients undergoing primary surgical treatment of PA/VSD/MAPCAs. There were three pathways employed to accommodate the various forms of this heart defect. The dominant pathway is midline unifocalization, which was utilized in 80% of all patients. Less frequently employed strategies included creation of an aortopulmonary window (15%), and other approaches (5%). Results: For the patients who underwent a midline unifocalization, 85% had a single-stage complete repair while 15% had a unifocalization and shunt. The operative mortality was 1.5% for the single-stage complete repair group vs. 8% for the unifocalization/shunt group. Ultimately, 97% of the midline unifocalization patients were repaired. However, the mean right ventricle to aortic pressure ratio was lower in patients who had a single-stage complete repair compared with an initial unifocalization/shunt (0.36±0.09 vs.
