Reoperation for Left Ventricular Outflow Tract Obstruction After Repair of Atrioventricular Septal
Abstract: Left ventricular outflow tract obstruction (LVOTO) is an important source of morbidity and mortality after repair of atrioventricular septal defect (AVSD). The intrinsic anatomy of the left ventricular outflow tract in AVSD is complex and predisposes to the development of LVOTO. LVOTO after repair of AVSD usually involves multiple levels and sources of obstruction, and surgical intervention must address each component of the obstruction. This includes fibromuscular obstruction, septal hypertrophy, and valve related sources of obstruction. Special attention is also directed to the anterolateral muscle bundle of th...

A Modification of the Pulmonary Autograft Procedure to Prevent Late Autograft Dilatation
This article reviews a technique we have used in 36 patients since October, 2004 that stabilizes the autograft so that it cannot dilate. There have been no operative or late deaths and the autograft has continued to function in 34 patients. Two patients have undergone autograft replacement because of early failure, which we believe was likely related to technical considerations in our early technique (first reported in the 2005 STCVS Pediatric Cardiac Surgery Annual). The technical modifications described in this article have produced a more reliable and reproducible technique and have not resulted in any autograft failure...

Tetralogy of Fallot and Pulmonary Valve Replacement: Timing and Techniques in the Asymptomatic Patient
This article examines the current literature and presents guidelines regarding pulmonary valve replacement in the asymptomatic patient. Also, in the current era of percutaneous valve replacement, certain technical considerations should be given toward valve replacement and are discussed as well.

When Repair is not Feasible: Prosthesis Selection in Children and Adults with Congenital Heart Disease
Abstract: Congenital heart surgeons face many challenges when dealing with valvular pathology in the pediatric population. Because of the concerns related to growth, repair should be the main goal. However, this is not always feasible and valve replacement becomes the only other alternative. Valve replacement also represents one of the most common procedures performed for adults with congenital heart disease, with several valve options existing including homografts, xenografts, autografts, and other artificial prostheses. The choice sometimes may be difficult because there are advantages and disadvantages to each valve sub...

Reoperations for Pediatric and Congenital Heart Disease: An Analysis of the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database
Abstract: In this descriptive analysis, data in the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database pertaining to patients who underwent reoperative cardiac surgery were analyzed. Practice patterns and outcomes are described. Reoperative cardiac surgery for congenital heart disease is common, with one third of index operations in the database occurring subsequent to prior cardiothoracic operation(s) performed on cardiopulmonary bypass. This analysis suggests that a history of previous cardiac surgery does not independently confer a significant incremental risk of operative mortality, but that patients ...

Introduction
The 2014 Seminars in Thoracic and Cardiovascular Surgery Pediatric Cardiac Surgery Annual is a collection of manuscripts derived from the presentations at the 2013 AATS Post Graduate Course and Skills Course in congenital heart surgery. The two courses were dedicated to the theme of reoperations in congenital heart disease. A concerted effort was made to coordinate topics between the Saturday Skills course and the Sunday Post Graduate course that address strategies for reoperation, technical aspects of the redo, and outcomes for various categories of congenital heart disease that require reoperation(s). The format for this...

In Favor of the Hybrid Stage 1 as the Initial Palliation for Hypoplastic Left Heart Syndrome
There are many reasons to consider using the Hybrid Stage 1 procedure as the initial palliation for hypoplastic left heart syndrome. It allows all options for treatment, including a delayed traditional approach, as well as a platform to evolve our overall approach to this challenging heart defect.

Neonatal Cardiopulmonary Bypass
Cardiac surgery with cardiopulmonary bypass is routinely used in neonates who require early repair of congenital heart diseases. However, the bypass temperature and use of deep hypothermic circulatory arrest, the composition of the priming and the acceptable degree of hemodilution, the prophylactic use of antifibrinolytic agents and steroids, the choice of myocardial protection, the best PaO2, and even the pump flow, are still subjects of debate, despite major improvements in neonatal bypass over the last decade. Nevertheless, there are some techniques that have reached a near-consensus and are highly recommended in neonat...

The Norwood Procedure: In favor of the RV-PA Conduit
Evolution of the Norwood procedure has culminated in there currently being three treatment strategies available for initial management: the ‘classical’ Norwood (utilizing a Blalock-Taussig shunt), the Norwood with right-ventricle to pulmonary artery (RV-PA) conduit, and the ‘hybrid’ Norwood procedure utilizing bilateral pulmonary artery banding and ductal stenting. Each variant has its potential advantages and disadvantages, and this paper looks to examine the evidence in favor of each strategy, with emphasis on the supportive data for the RV-PA conduit. The ‘classical’ procedure has the benefit of the greatest...

The Neonatal Hypoplastic Aortic Arch: Decisions and More Decisions
Neonatal patients with hypoplasia of the aortic arch constitute a heterogeneous group with a wide spectrum of severity. The milder end of the spectrum comprises patients with aortic coarctation and isthmus hypoplasia. At the other end of the spectrum are patients with severe transverse arch hypoplasia or hypoplastic left heart syndrome. The aim of this paper is to discuss the various strategies and surgical approaches available for this group of patients, focusing on the surgical decisions that influence individual patient management. Many of the things discussed are applicable to any neonatal arch problem. We also describ...

Strategies to Maintain Biventricular Circulation in Patients With High-Risk Anatomy
Although hypoplasia of left heart structures presents with a spectrum of severity, management decisions are typically dichotomous: single-ventricle palliation or biventricular repair. Since the long-term outcomes of single-ventricle palliation are sub-optimal, strategies to aggressively pursue biventricular circulation in patients with borderline left heart structures have been developed. Recent strategies and surgical techniques to rehabilitate the left heart in patients with borderline left heart are described.

Unbalanced Atrioventricular Septal Defect: Defining the Limits of Biventricular Repair
Unbalanced atrioventricular septal defect (uAVSD) is a challenging lesion with suboptimal outcomes in the current era. Severe forms of uAVSD mandate univentricular repair with well-documented outcomes. Determining the feasibility of biventricular repair (BVR) in patients with moderate forms of uAVSD is difficult. Ventricular hypoplasia has traditionally formed the cornerstone of defining uAVSD. However, malalignment of the atrioventricular junction and related derangements of the anatomy and physiology of the atrioventricular inflow play a central role in establishing and sustaining a biventricular end state. Atrioventricu...

Neonatal Cardiac Care, a Perspective
Every year in the United States approximately 40,000 infants are born with congenital heart disease. Several of these infants require corrective or palliative surgery in the neonatal period. Mortality rates after cardiac surgery are highest amongst neonates, particularly those born prematurely. There are several reasons for the increased surgical mortality risk in neonates. This review outlines these risks, with particular emphasis on the relative immaturity of the organ systems in the term and preterm neonate.
