Reoperation after surgical repair of tetralogy of fallot

BACKGROUND: Recently, improvements in the repair of tetralogy of Fallot have increased the need for reoperation in adulthood, and it's not rare that these reoperation candidates suffer from biventricular failure. However, there are no firm treatment guidelines, and each country, and even each facility, treats each case individually. CASE PRESENTATION: We report the successful staged treatment of pulmonary regurgitation and pacemaker-induced cardiomyopathy with biventricular failure in adulthood in a case of complete atrioventricular block after tetralogy of Fallot repair in childhood...

A 33-year-old man, who had previously undergone repair for Tetralogy of Fallot, presented with extensive infective endocarditis. Following thorough preoperative preparation and evaluation, we performed a simultaneous quadruple valve replacement alongside the repatching of the remaining defect. We posit that this comprehensive one-stage surgical intervention not only enhanced the patient's quality of life but also reduced the necessity for future reoperations. Our approach offers valuable insights for managing adult patients with repaired congenital heart diseases and multiple valve pathologies...

Atrioventricular septal defect (AVSD) in association with tetralogy of Fallot (TOF) is a rare and complex congenital cardiac malformation. We report our institutional experience and outcomes following surgical correction over a 20-year period. Patients who underwent combined surgical AVSD and TOF correction between October 2001 and February 2020 were included for analysis. All patients underwent primary repair. The study data were prospectively collected and retrospectively analyzed. Primary outcomes were in-hospital mortality and long-term freedom from reoperation...

OBJECTIVES: To review outcomes after a uniform strategy of transventricular repair of tetralogy of Fallot (TOF). METHODS: A total of 244 consecutive patients underwent transventricular primary repair of TOF from 2004 to 2019. Median age at operation was 71 days; 57 (23%) patients were premature; 57 (23%) patients had low birth weight (<2.5kg) and 40 (16%) genetic syndromes. The diameter of pulmonary valve annulus, right pulmonary artery (PA) and left PA were 6...

BACKGROUND: Surgical repair of tetralogy of Fallot (ToF) depends on the anatomical variations of the heart defect. A group of patients with a hypoplastic pulmonary valve annulus required a transannular patch. This study aimed to evaluate the early and late outcomes of ToF repair with a transannular Contegra® monocuspid patch in a single center. METHODS: A retrospective review of medical records was conducted. This study included 224 children with a median age of 13 months who underwent ToF repair with a Contegra® transannular patch in over 20 years of observation...

OBJECTIVE: Surgery for heart defects in children with trisomy 13 or 18 is controversial. We analyzed our 20-year experience. METHODS: Since 2002, we performed 21 operations in 19 children with trisomy 13 (n = 8) or trisomy 18 (n = 11). Age at operation was 4 days to 12 years (median, 154 days). Principal diagnosis was ventricular septal defect in 10 patients, tetralogy of Fallot in 7 patients, arch hypoplasia in 1 patient, and patent ductus arteriosus in 1 patient...

Initial management of patients with tetralogy of Fallot, unfavorable anatomy, and reduced pulmonary blood flow is controversial and continues to be a clinical challenge. Pulmonary to systemic shunt anastomosis or primary correction in neonates and small infants is associated with higher morbimortality and increased number of reoperations. Initial right ventricle outflow tract stenting palliation has emerged as an attractive alternative. We report our experience in 14 patients operated on with tetralogy of Fallot and previous right ventricle outflow tract stenting from March 2018 to June 2022...

BACKGROUND: The optimal management strategy for symptomatic young infants with tetralogy of Fallot (TOF) is yet to be determined. We aimed to evaluate the long-term outcomes of a staged approach with initial shunt palliation followed by complete repair. METHODS: Between January 1993 and July 2021, 160 children with TOF underwent a systemic-to-pulmonary shunt at our institution, including 65 neonates (41%). The mean duration of follow-up was 12.3 ± 8...

Objectives: The study objectives were to reconfirm the superiority of the pulmonary valve-sparing procedure versus the transannular patch procedure for repair of tetralogy of Fallot and to evaluate the influence of a right ventriculotomy in the pulmonary valve-sparing procedure. Methods: Between 1978 and 2003, 440 patients (aged <10 years) underwent tetralogy of Fallot repair. Of these patients, 242 (55.0%) underwent the transannular patch procedure, 106 (24...

BACKGROUND:  The aim of this study was to evaluate the long-term outcome and freedom from pulmonary valve replacement (PVR) after initial repair of tetralogy of Fallot (TOF). PATIENTS AND METHODS:  The cohort of 306 patients treated between 1980 and 2017 was divided into anatomical subgroups according to the diagnosis of TOF-pulmonary stenosis, TOF-pulmonary atresia and TOF-double outlet right ventricle. Patients were treated with transannular patch (TAP), valve sparing repair (VSR), or conduits from the right ventricle to the pulmonary arteries (RVPA conduits)...

This new and easily reproducible pulmonary valve-sparing technique for the correction of Tetralogy of Fallot is based on a conservative management of the native pulmonary valve to preserve its growth potential. From July 2015 to December 2019, 67 children presenting with a Tetralogy of Fallot were operated consecutively in a single centre using this technique in all cases. A T-shaped infundibulotomy is used to release the anterior pulmonary annulus from any muscular attachment. After myocardial resection and ventricular septal defect closure, an extensive commissurotomy is achieved...

BACKGROUND: Although valve-sparing repair remains ideal for patients with tetralogy of Fallot, the durability of valve-sparing repair and which patients may have been better served with a transannular patch remain unclear. METHODS: Retrospective review was performed of tetralogy of Fallot operations at our institution from January 2008 to December 2018. Standard demographic data were collected, including echocardiographic parameters, operative details, and clinical outcomes...

As more patients with congenital heart disease survive the definitive surgical repair, more attention has paid to their residual defects or late sequela which required surgical re-intervention. Redo-right ventricular outflow tract reconstruction is the most frequent reoperation, mostly indicated for pulmonary regurgitation after tetralogy of Fallot repair, or conduit stenosis in post-Rastelli patients. For patients with significant chronic pulmonary regurgitation, reoperation should be considered before right ventricular geometry and function becomes irreversible...

OBJECTIVE: We studied a cohort of patients with nonsyndromic complete atrioventricular septal defect with and without concomitant complex cardiac anatomy and compared the outcomes after surgical repair. METHODS: Between 1993 and 2018, 62 nonsyndromic patients underwent complete atrioventricular septal defect repair. Sixteen patients (26%) had complex complete atrioventricular septal defect with variables representing concomitant cardiac anatomic complexity: tetralogy of Fallot, double outlet right ventricle, total anomalous pulmonary venous return, concomitant aortic arch reconstruction, multiple ventricular septal defects, staged repair of coarctation of the aorta, and a persisting left superior vena cava...

OBJECTIVES: Previous studies investigating risk factors associated with reoperation or mortality after repair of complete atrioventricular septal defect (CAVSD) often have not included sizeable cohorts undergoing modified single-patch repair. Both double patch and modified single-patch techniques have been widely used in Australia since the 1990s. Using a large multi-institutional cohort, we aimed to identify risk factors associated with reoperation or mortality following CAVSD repair...

BACKGROUND: Pericardial patches are often used for repair of congenital cardiac defects. The aim of this study was to describe our initial experience with the use of equine pericardium and its safety and advantages and disadvantages compared to bovine pericardium. METHODS: We designed a retrospective cohort study of 111 patients who were surgically treated for congenital heart disease between 2017 and 2020. Equine pericardium was used in 58 patients and bovine pericardium was used in 53 patients...

OBJECTIVES: Pulmonary valve replacement (PVR) performed for pulmonary valve regurgitation is the most common indication for reoperation during mid-to-long-term follow-up after tetralogy of Fallot repair. An aneurysmal dilation of the infundibulum is often associated secondary to the infundibulotomy performed in the first operation. The right ventricular outflow tract reconstruction with endo-exclusion aims to exclude the non-contractile segments of the dilated right ventricular. This study intends to assess the safety and efficiency of the endo-exclusion technique...

Isolated pulmonary artery (PA) of ductal origin (IPADO) is a rare cardiac defect which requires surgical repair, with or without preceding palliation. We sought to determine the impact of treatment strategy on outcomes. Retrospective study of consecutive patients with IPADO that underwent staged or primary repair from 1/05 to 9/16 at 6 Congenital Cardiac Research Collaborative centers. Patients with single ventricle physiology, major aortopulmonary collaterals, or bilateral IPADO were excluded. Primary outcome was isolated PA z-score at late follow-up...

Introduction Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect. Objectives To evaluate long-term outcomes of patients who underwent complete repair of TOF at our institution and to compare the outcomes of patients with pulmonary valve- -sparing repair (annulus preserved) versus patients with a transannular patch. We also evaluated the rate of growth of the pulmonary valve annulus and pulmonary arteries. Materials and Methods Retrospective study of 142 consecutive children with TOF admitted between April 1998 and April 2019, excluding 4 patients who only had palliative surgery without posterior complete repair and 5 patients who received a right ventricle to main pulmonary artery (RV-PA) conduit with a pulmonary homograft...

OBJECTIVES: Chronic pulmonary valve (PV) regurgitation is a common late sequela after repair of congenital heart diseases like tetralogy of Fallot or pulmonary stenosis, leading to right ventricular dilatation and failure and increased late morbidity and mortality. Timely reoperation may lead to a complete right ventricular recovery. An injectable PV allows pulmonary valve replacement, with or without cardiopulmonary bypass, under direct observation, thereby minimizing the impact of surgery on cardiac function...
