Conotruncal heart malformations
MONDO:0016581Conotruncal heart malformations are a group of congenital cardiac outflow tract anomalies that include such defects as tetralogy of Fallot, pulmonary atresia with ventricular septal defect, double-outlet right ventricle (DORV), double-outlet left ventricle, truncus arteriosus and transposition of the great arteries (TGA), among others. This group of defects is frequently found in patients with 22q11.2 deletion syndrome. A deletion of chromosome 22q11.2 has equally been associated in a subset of patients with various types of isolated non-syndromic conotruncal heart malformations (with the exception of DORV and TGA where this is very uncommon).
Also known as: Taussig-Bing syndrome or defect, conotruncal heart malformations, conotruncal heart malformations, variable, CTHM, Double-outlet right ventricle, conotruncal anomaly face syndrome, conotruncal cardiac defects, interrupted aortic Arch

New heart valve trial offers hope for patients with rare congenital defects
Disease control Recruiting nowThis study is testing a new heart valve (SAPIEN 3) in 108 people who have a dysfunctional right ventricle outflow tract (RVOT) due to a congenital heart defect or a previous valve replacement. The goal is to see if the valve is safe and effective at improving blood flow and reduc…

New trial aims to halve deaths in newborns with severe heart disease
Disease control Recruiting nowThis study compares performing heart surgery on newborns with complex congenital heart disease either before or after 7 days of age. Researchers will track which timing leads to fewer deaths and better recovery. The trial involves 738 babies across multiple hospitals in China.

Could a common heart drug spark new muscle growth in babies with heart defects?
Disease control Recruiting nowThis early-stage trial tests whether the beta-blocker propranolol can stimulate heart muscle cell growth in infants born with Tetralogy of Fallot, a serious heart defect. Forty infants under 60 days old will receive propranolol, and researchers will measure new heart muscle cells…

New trial tests if operating on Newborns' hearts within 28 days beats waiting months
Disease control Recruiting nowThis study compares two surgical timings for babies born with Tetralogy of Fallot, a serious heart defect. One group gets corrective surgery within 28 days of birth, the other at the usual 3-6 months. Researchers will track deaths, reoperations, and recovery to see if earlier sur…

Home workouts could boost heart health for congenital heart patients
Symptom relief Recruiting nowThis study tests whether a 12-week home-based high intensity interval training program can improve exercise capacity in people aged 12 to 45 with a congenital heart defect that required a surgical connection between the right ventricle and pulmonary artery. Participants are rando…

Could a headset boost brainpower in teens with a rare genetic condition?
Symptom relief Recruiting nowThis study tests whether a gentle brain stimulation technique called tACS, used at home for 5 days a week over 4 weeks, can improve memory and thinking in 40 young people aged 14-25 with 22q11.2 deletion syndrome. The stimulation is personalized based on each participant's MRI an…

Can baby hearts regrow? scientists seek answers in tiny tissue samples
Knowledge-focused Recruiting nowThis study aims to measure how well infants' hearts can make new muscle cells, especially in those with a heart condition called Tetralogy of Fallot. Researchers will use a special imaging technique on heart tissue that is normally removed and thrown away during surgery. The goal…
