A 50 year old man with a past medical history of Tetralogy of Fallot and status post surgical repair at age 2 was found to have complete heart block with a ventricular escape rhythm of 37 beats per minute (bpm) on an electrocardiogram (ECG) performed during his annual physical exam.

BACKGROUND: Myocardial fibrosis is linked with adverse clinical outcomes in adults after tetralogy of Fallot repair (rTOF). Native T1 times (T1) by cardiac magnetic resonance have been shown to be a surrogate marker of diffuse myocardial fibrosis. The objective was to quantify native T1 in children post-rTOF and to evaluate their relationship with surgical, imaging, and clinical factors. METHODS AND RESULTS: A retrospective cross-sectional study was performed. Midventricular native T1 were obtained in 100 children post-rTOF using a modified look-locker inversion recovery cardiac magnetic resonance sequence and compared with 35 pediatric controls...

BACKGROUND: Pulmonary valve replacement (PVR) often is performed in adults with repaired tetralogy of Fallot (TOF). For patients who have tricuspid regurgitation (TR), tricuspid valve (TV) repair associated to PVR is still debated. OBJECTIVE: We sought to evaluate perioperative factors related to TV repair when performed at the time of PVR in patients with repaired TOF. METHODS: We retrospectively reviewed 104 patients with repaired TOF (or its equivalent) who underwent PVR (2002-2014)...

PURPOSE: Adults after surgical repair of tetralogy of Fallot (ToF) may have impaired vascular and cardiac autonomic function. Thus, we wanted to assess interrelations between heart rate variability (HRV) and heart rate recovery (HRR), as parameters of cardiac autonomic function, and arterial stiffness, as a parameter of vascular function, in adults with repaired ToF as compared to healthy controls. METHODS: In a case-control study of adults with repaired ToF and healthy age-matched controls we measured: 5-min HRV variability (with time and frequency domain data collected), carotid artery stiffness (through pulse-wave analysis using echo-tracking ultrasound) and post-exercise HRR (cycle ergometer exercise testing)...

Purpose The aim of this study was to determine whether the exercise tolerance test can provide diagnostic and prognostic information regarding children and young adults and help predict outcome. METHODS: A total of 87 patients, aged 7-29 years (median 13, mean 13.4) were selected retrospectively. They underwent exercise test at the Freeman Hospital from December, 2015 to May, 2016. There were two groups of patients - 46 had symptoms such as chest pain, palpitations, syncope, or dyspnoea on exertion and no cardiac diagnosis, and 40 patients had a cardiac diagnosis such as hypertrophic cardiomyopathy, transposition of the great arteries with post-arterial switch operation, aortic stenosis or regurgitation, tetralogy of Fallot, abnormal coronary arteries, Wolff-Parkinson-White syndrome, or supraventricular tachycardia...

BACKGROUND: Left atrial (LA) size predicts cardiovascular outcome in chronic heart failure. Its prognostic value in adults with repaired tetralogy of Fallot (ToF) is unknown. This study therefore investigated the association of LA size and function with cardiovascular events in adults with ToF. METHODS: Clinically stable adults with ToF who visited the outpatient clinic between 2011 and 2013 underwent echocardiography and were prospectively followed for the occurrence of death, heart failure, hospitalizations, arrhythmia, thromboembolic events, and re-interventions...

BACKGROUND: Left ventricular (LV) dysfunction in patients with repaired tetralogy of Fallot (rTOF) is an important risk factor for adverse outcomes. The aim of this study was to assess the details and time course of such LV dysfunction using layer-specific strain analysis by echocardiography.Methods and Results:The 66 patients with rTOF (mean age, 16.3±9.3 years) were divided into 3 groups (T1: 4-10 years, T2: 11-20 years, T3: 21-43 years), and 113 controls of similar age (mean age, 17...

Tetralogy of Fallot (TOF) is one of the most common forms of cyanotic congenital heart disease usually managed by serial surgical repairs. The repaired prosthetic valve or conduit is susceptible to life-threatening infection. FDG-PET is an effective alternative to evaluate the source of infection when other examinations are inconclusive. We report an unusual case of an infected pulmonary artery conduit after TOF repair although the echocardiogram was negative for vegetation, which was later confirmed by surgery and pathology...

Importance: Adults late after total correction of tetralogy of Fallot (TOF) are at risk for major complications. Cardiovascular magnetic resonance (CMR) imaging is recommended to quantify right ventricular (RV) and left ventricular (LV) function. However, a commonly used risk model by Khairy et al requires invasive investigations and lacks CMR imaging to identify high-risk patients. Objective: To implement CMR imaging in noninvasive risk stratification to predict major adverse clinical outcomes...

Percutaneous pulmonary valve implantation (PPVI) has become a widely practiced treatment option for patients with right ventricular outflow tract (RVOT) dysfunction. For this procedure, the Melody transcatheter pulmonary valve has become the most widely used system. On-label indications are limited to the treatment of failing circumferential conduits. However, there is growing but still limited experience with the off-label treatment of native or patched RVOTs. Here, the case is reported of a 57-year-old patient in whom redo-surgery for a dysfunctional pulmonary valve could be avoided by PPVI into the patched RVOT at 51 years after tetralogy of Fallot repair...

Philippe Maury, Frederic Sacher, Anne Rollin, Pierre Mondoly, Alexandre Duparc, Katja Zeppenfeld, Sebastien Hascoet
Malignant ventricular arrhythmias and sudden cardiac death may late happen in repaired tetralogy of Fallot, although probably less frequently than previously thought, especially with the advent of new surgical techniques/management. Ventricular tachycardias are caused by reentry around the surgical scars/patches and valves. Many predictive factors have been proposed, which suffer from poor accuracy. There is currently no recommended indication for prophylactic implantable cardioverter defibrillator implantation-except maybe in the case of multiple risk factors-while radiofrequncy ablation may be proposed in secondary prevention with or even without a back-up implantable cardioverter defibrillator in selected cases...

Tetralogy of Fallot (TOF) is the most frequently diagnosed congenital cyanotic heart disease. It is often associated with additional findings, such as atrial septal defect (i.e., pentalogy of Fallot) or right sided aortic arch. Association of this pentalogy of Fallot with situs inversus totalis is rarely reported in paediatric literature and it can cause technical challenges to intracardiac repair. We report the case of pentalogy of Fallot with dextrocardia and situs inversus presenting as parieto-occipital abscess in a 12-year-old child...

Background: Three-dimensional (3D) echocardiography coupled with speckle-tracking echocardiographic (STE) capability is a novel methodology which has been demontrated to be useful for the assessment of left atrial (LA) volumes and functional properties. There is increased scientific interest on myocardial deformation analysis in adult patients with corrected tetralogy of Fallot (cTOF). Objectives: To compare LA volumes, volume-based functional properties and strain parameters between cTOF patients and age- and gender-matched healthy controls...

BACKGROUND: Transcatheter pulmonary valve implantation (TPVI) with the Melody® transcatheter pulmonary valve (TPV) has demonstrated good haemodynamic and clinical outcomes in the treatment of right ventricular outflow tract (RVOT) conduit dysfunction in patients with repaired congenital heart disease CHD. We present the first Australian single centre experience of patients treated with Melody TPV. METHOD: A prospective, observational registry was developed to monitor clinical and haemodynamic outcomes in patients with RVOT dysfunction treated with the Melody TPV (Medtronic Inc, Minneapolis, United States)...

A 38-year-old female patient with a history of tetralogy of Fallot repair at 10 years of age underwent pulmonary valve replacement with a mechanical prosthesis, tricuspid annuloplasty, and right ventricular outflow tract cryoablation due to pulmonary regurgitation, tricuspid regurgitation, and multiple premature ventricular contractions with sustained ventricular tachycardia. After surgery, she had an uneventful postoperative course with arrhythmia monitoring. She was discharged without incident, and a follow-up Holter examination showed a decrease in the number of ventricular ectopic beats from 702 to 41...
