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.

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...
Atrioventricular valve regurgitation is known to adversely impact outcomes of single-ventricle palliation, and valve repair rarely provides long-lasting results. Closure of a atrioventricular valve ca...
We describe an asymptomatic 7 year old boy who was taken to the operating room for repair of a subaortic membrane and possible Gerbode's defect. He was found to have a double outlet right atrium assoc...
Biventricular repair of complete atrioventricular septal defect (CAVSD) is largely achieved using the double-patch (DP) or modified single-patch (MSP) techniques in the current era, however long-term ...
Atrioventricular valve development relies upon the precisely defined dimensions of the atrioventricular canal (AVC). Current models suggest that Wnt signaling plays an important role atop a pathway th...
The purpose of this study is to determine the optimal timing for repair of left-to-right shunt lesions such as ventricular septal defects and atrioventricular canals.
In this study a new technique for ablation in atrioventricular nodal reentrant tachycardia using cryo-energy will be studied in cases where the standard approach has higher risk.
To identify genes involved in the pathogenesis of three types of congenital heart disease, atrial septal defects, paramembranous ventricular septal defects, and atrioventricular canal defe...

The purpose of the study is to assess the role of mitral valve apparatus in the development of outflow tract obstruction in patients with hypertrophic cardiomyopathy and to identify the be...
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).
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
