A new method for atrioventricular valve repair in atrioventricular septal defect.

Summary of "A new method for atrioventricular valve repair in atrioventricular septal defect."

The left atrioventricular valve in atrioventricular septal defect is conventionally repaired by suturing the "cleft". This may be complicated with stretching/dehiscence of the sutured zone by naturally-diverging cordal traction, and stenosis by restricting leaflet mobility. This prompted us to develop a different approach, especially for adults and adolescents, who may or may not have undergone surgical repair previously. It consists in not closing/re-opening the "cleft", constructing neo-cordae connecting the cordless edge of each bridging leaflet to the opposite papillary muscle, i.e. the papillary muscle to which it has no natural connection ("crossing neo-cordae"), and inserting an annuloplasty ring.

Twelve Years of Complete Atrioventricular Septal Defect Repair.

Surgical repair is the standard treatment for complete atrioventricular septal defect. At our institution, this repair is performed by single patch, modified single patch or two patch techniques, acco...

Medical and Biotech [MESH] Definitions

A spectrum of septal defects involving the ATRIAL SEPTUM; VENTRICULAR SEPTUM; and the atrioventricular valves (TRICUSPID VALVE; BICUSPID VALVE). These defects are due to incomplete growth and fusion of the ENDOCARDIAL CUSHIONS which are important in the formation of two atrioventricular canals, site of future atrioventricular valves.

A small nodular mass of specialized muscle fibers located in the interatrial septum near the opening of the coronary sinus. It gives rise to the atrioventricular bundle of the conduction system of the heart.

A rare form of supraventricular tachycardia caused by automatic, not reentrant, conduction initiated from sites at the atrioventricular junction, but not the ATRIOVENTRICULAR NODE. It usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication with a HEART RATE ranging from 140 to 250 beats per minute.

A fetal heart structure that is the bulging areas in the cardiac septum between the HEART ATRIA and the HEART VENTRICLES. During development, growth and fusion of endocardial cushions at midline forms the two atrioventricular canals, the sites for future TRICUSPID VALVE and BICUSPID VALVE.

A developmental abnormality in which the spiral (aortopulmonary) septum failed to completely divide the TRUNCUS ARTERIOSUS into ASCENDING AORTA and PULMONARY ARTERY. This abnormal communication between the two major vessels usually lies above their respective valves (AORTIC VALVE; PULMONARY VALVE).
