Cardiac magnetic resonance imaging in repaired tetralogy of Fallot: A longitudinal midterm follow-up study.
PLoS One
December 2024
Rajaie Cardiovascular Medical and Research Center, Iran University of Medical Sciences, Tehran, Iran.
Background: Biventricular dysfunction is frequent in patients with repaired tetralogy of Fallot, necessitating routine imaging to monitor for worsening conditions and determine whether procedures like pulmonary valve replacement (PVR) are needed. This study aimed to highlight the parameters of cardiac magnetic resonance imaging (CMR) and their association with adverse outcomes in the midterm follow-up of these patients.
Methods: This longitudinal study recruited all patients with a history of tetralogy of Fallot total correction (TFTC) who had two CMR images at a minimum three-month interval at Rajaie Center from 2007 through 2017.

Post-operative transesophageal echocardiography (TEE) is standard of care to evaluate for residual disease and quality of surgical repair. The residual lesion score (RLS) as defined by the pediatric heart network explored the impact of residual lesions on outcomes using discharge transthoracic echocardiogram (TTE). In tetralogy of fallot with pulmonary stenosis (TOF/PS), the residual right ventricular outflow tract (RVOT) gradient is one marker of quality of repair.

Department of Bioengineering, Stanford University, Stanford, CA, USA.
Purpose: Pulmonary valve replacement (PVR) using bioprosthetic valves is a common procedure performed in patients with repaired Tetralogy of Fallot and other conditions, but these valves frequently become dysfunctional within 15 years of implantation. The causes for early valve failure are not clearly understood. The purpose of this study was to explore the impact of changing cardiac output (CO) and valve orientation on local hemodynamics and valve performance.

Article Synopsis
- Ventricular septal defect (VSD) is the most common type of congenital heart disease and often requires surgical intervention.
- The VSD patch closure surgery is crucial not only for simple VSDs but also for more complex congenital heart defects like tetralogy of Fallot and complete atrioventricular septal defect.
- To ensure successful closure without complications, surgeons must have a thorough understanding of VSD anatomy and skillfully perform sutures and ligatures.

Department of Radiology, Children's Hospital of Nanjing Medical University, Nanjing, Jiangsu Province, China.
Article Synopsis
- Cognitive impairment is a common issue in children with congenital heart disease (CHD), particularly in those with Tetralogy of Fallot (TOF), and this study explores how TOF affects brain network organization.
- The research involved 29 preschool-aged children with TOF and 19 without CHD, utilizing diffusion tensor imaging to analyze brain structures, revealing significant differences in network properties between the two groups.
- Key findings indicate that TOF children showed impaired brain connectivity and efficiency, which correlated with poorer cognitive performance, suggesting that disruptions in brain network integration could underlie cognitive deficits in these children.

Article Synopsis
- The study examined the use of right ventricular outflow tract (RVOT) stenting versus the modified Blalock-Taussig shunt (mBTS) as treatments for children with stenotic RVOTs aged 1 to 18, revealing limited literature on their comparative effectiveness.* -
- Data from 58 patients indicated that both procedures resulted in similar rates of major adverse cardiovascular events (MACE), but mBTS patients had shorter overall hospital stays, while RVOT stenting led to shorter ICU stays.* -
- Overall, RVOT stenting showed comparable results to mBTS concerning MACE and oxygen saturation levels at discharge, suggesting it could be a viable option for palliation in this patient population.*

University Health Network Toronto, Peter Munk Cardiac Centre, and University of Toronto, Toronto, Ontario, Canada.
Article Synopsis
- The study investigates the effectiveness of intracardiac echocardiography (ICE) in improving catheter ablation outcomes for ventricular tachycardia (VT) in adults with repaired tetralogy of Fallot (TOF).
- Results showed that ICE significantly enhanced isthmus localization and ablation success rates, but did not improve long-term freedom from VT or affect overall procedural times and complications.
- The conclusion emphasizes that while ICE is beneficial for tailored ablation based on individual anatomy, it does not lead to better long-term patient outcomes for VT in the context of repaired TOF.

Department of Obstetrics and Gynecology, Division of Fetal Medicine, Erasmus Medical Center, Rotterdam, The Netherlands.
Article Synopsis
- Fetal two-dimensional speckle tracking echocardiography (2D-STE) assesses fetal heart function by measuring global longitudinal strain (GLS) and strain rate (GLSR), which indicate how the heart walls stretch and deform.
- The systematic review found that fetuses with congenital heart diseases (CHD) like coarctation of the aorta and Tetralogy of Fallot have significantly lower LV-GLS, while those with a single left ventricle show higher LV-GLS values.
- The study highlights the need for more longitudinal research on 2D-STE in fetuses with CHD to better interpret the findings and explore its potential in predicting outcomes, given the observed variability across different

Article Synopsis
- This study reviews surgical outcomes of pulmonary valve replacements in adults with congenital heart disease, specifically focusing on patients who underwent this procedure over the past decade.
- A total of 79 patients were analyzed, with the majority having Tetralogy of Fallot, and the surgery involved removing the old valve and using a larger bioprosthesis, often alongside other surgeries like tricuspid valve repairs.

Discipline of Medical Radiation Science, Curtin Medical School, Curtin University, Perth, WA 6845, Australia.
Article Synopsis
- Diagnosing congenital heart disease (CHD) is tough due to its complex structures and variability, making conventional 2D visualizations inadequate.
- This study explored the effectiveness of four different visualization tools: DICOM images, 3D-printed heart models (3DPHM), virtual reality (VR), and 3D PDFs, using three CHD cases.
- Results showed that 76.4% of specialists preferred VR for understanding spatial relationships in the heart and presurgical planning, while 94.1% favored 3DPHM for patient communication and education, highlighting the strengths of both advanced technologies.
