Technique for Neo-Pulmonary Valve Creation With Living Tissue for Repair of Atrioventricular Septal Defect and Tetralogy of Fallot.

World J Pediatr Congenit Heart Surg 2022 Jul;13(4):499-502

Department of Surgery, Division of Cardiothoracic Surgery, Section of Pediatric Cardiothoracic Surgery, 12275Washington University School of Medicine, St. Louis Children's Hospital, St. Louis, Missouri, USA.

Long-standing effects of pulmonary regurgitation after transannular patch repair in Tetralogy of Fallot (ToF) can be especially deleterious in the setting of combined ToF and complete atrioventricular septal defect (CAVSD). We present a technique for a complete repair of combined ToF/CAVSD using right atrial appendage tissue to create a competent neo-pulmonary valve. This technique provides advantages of right heart protection via pulmonary valve competence and the use of living tissue capable of growth with the patient, potentially obviating the need for repeat interventions.

Integrated multiomic characterization of congenital heart disease.

Nature 2022 Jun 22. Epub 2022 Jun 22.

Program in Developmental Biology, Baylor College of Medicine, Houston, TX, USA.

The heart, the first organ to develop, undergoes complex morphogenesis that when defective results in congenital heart disease (CHD). With current therapies, more than 90% of CHD patients survive into adulthood but often suffer premature death from heart failure (HF) and non-cardiac causes . To gain insight into poorly understood disease progression, we performed single nuclear RNA sequencing (snRNA-seq) and analyzed 157,273 nuclei from donors and CHD patients, including hypoplastic left heart syndrome (HLHS) and Tetralogy of Fallot (TOF), two common forms of cyanotic CHD lesions, as well as, dilated (DCM) and hypertrophic (HCM) cardiomyopathies.

Cardiol Young 2022 Jun 22:1-8. Epub 2022 Jun 22.

Department of Cardiology, Santa Marta Hospital, Centro Hospitalar Universitário de Lisboa Central, Lisbon, Portugal.

A 40-year-old female is admitted for paroxysmal episodes of exertional dyspnoea, with associated cyanosis, improving with squatting, and a holosystolic murmur radiating to the interscapular area. Echocardiography showed a subaortic ventricular septal defect with left-to-right shunt and overriding aorta. The characteristic murmur prompted us to seek right ventricular outflow tract obstruction.

Baz1b Dosage Influences Cardiovascular Function, Predisposing to Dilated Cardiomyopathy.

FASEB J 2022 May;36 Suppl 1

Laboratory of Vascular and Matrix Genetics, National Heart, Lung, and Blood Institute, Bethesda, MD.

BAZ1B is one of several genes deleted in Williams-Beuren Syndrome (WBS), a complex, multisystem genetic condition that occurs in ~1 in 8000 live births. Also known as Williams Syndrome Transcription Factor (WSTF), BAZ1B is thought to be essential for neural crest migration. To evaluate the impact of Baz1b loss of function, we evaluated the "knockout first" allele of Baz1b . Read More

Joint analysis of functionally related genes yields further candidates associated with Tetralogy of Fallot.

J Hum Genet 2022 Jun 20. Epub 2022 Jun 20.

Division of Cardiovascular Sciences, School of Medical Sciences, Faculty of Biology, Medicine and Health, The University of Manchester, Manchester, UK.

Although several genes involved in the development of Tetralogy of Fallot have been identified, no genetic diagnosis is available for the majority of patients. Low statistical power may have prevented the identification of further causative genes in gene-by-gene survey analyses. Thus, bigger samples and/or novel analytic approaches may be necessary.

Nork-Marash Medical Center, Armenak Armenakyan St. 13, 0047 Yerevan, Armenia.

Background: Tetralogy of Fallot (TOF) is one of the most widespread cyanotic congenital heart disease (CHD), which can be successfully repaired in the neonatal period. However, residual problems and the surgical technique itself can create a favourable basis for arrhythmias and conduction abnormalities in these patients. Sometimes, these arrhythmias may worsen during pregnancy and require urgent intervention. Read More

Mol Genet Genomics 2022 Jun 7. Epub 2022 Jun 7.

Department of Genetics, Dr. ALM PG Institute of Basic Medical Sciences, University of Madras, Taramani, Chennai, Tamil Nadu, 600113, India.

Congenital heart disease (CHD) surges from fetal cardiac dysmorphogenesis and chiefly contributes to perinatal morbidity and cardiovascular disease mortality. A continual rise in prevalence and prerequisite postoperative disease management creates need for better understanding and new strategies to control the disease. The interaction between genetic and non-genetic factors roots the multifactorial status of this disease, which remains incompletely explored. Read More

Repair with a pulmonary neovalve in tetralogy of fallot. DOES this avoid ventricular dysfunction?

Interact Cardiovasc Thorac Surg 2022 May 30. Epub 2022 May 30.

Cardiovascular Surgeon, Department of Cardiovascular Surgery, Fundación Cardioinfantil-IC. Rosario University.

Introduction: Given the anatomical variations of tetralogy of Fallot (TOF), different surgical techniques can be used to achieve correction. Transannular patches are the most commonly used technique; they are associated with right ventricular dysfunction, the incidence of which can be reduced through pulmonary valve preservation.

Methods: Between January 2010 and July 2019, we performed 274 surgical corrections of TOF at Fundación Cardioinfantil; 63 patients (23%) underwent repair with a transannular patch in addition to a pulmonary neovalve (Group I), 66 patients (24. Read More

Right Ventricular Outflow Tract Surgical Resection in Young, Large Animal Model for the Study of Alternative Cardiovascular Patches.

Methods Mol Biol 2022 ;2485:299-309

Cellular, Molecular and Developmental Biology Program, Graduate School of Biomedical Sciences, Tufts University, Boston, MA, USA.

Tetralogy of Fallot (ToF) is a severe congenital heart defect (CHD) that requires surgical reconstruction soon after birth. Reconstructive surgery involves the implantation of synthetic cardiovascular patches to widen the right ventricular outflow tract (RVOT) and repair defects in the septal wall. However, synthetic patches can cause complications for these patients later in life as they do not integrate or adapt in the tissue of a growing patient; a limitation that could be solved with the development of a patch fabricated from a degradable biomaterial.
