Totally Endoscopic Surgical Repair of Partial Atrioventricular Septal Defect in Children: Two Cases
In this report, we present two children who were successfully repaired partial atrioventricular septal defect by using totally endoscopic surgery without robotic assistance.
AbstractDespite improvements in valve repair techniques, conditions in which infants and children need for mechanical valve replacement (MVR) are still present. We analyzed supra-annular MVR outcomes in infants and children with small annulus and compared them with conventional annular MVR outcomes. Data were collected retrospectively from medical records of infants and children (weighing
Publication date: Available online 26 November 2019Source: The Annals of Thoracic SurgeryAuthor(s): Antonio González-Calle, Alejandro Adsuar-Gómez, Amir-Reza HosseinpourAbstractThe 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. I...
ConclusionsSecondary subaortic stenosis (SSS) occurs after DORV surgery. The Konno operation or the RRIB can be selected for surgical correction, which is more satisfactory and safer for the treatment of stenosis. For patients with SSS after the operation of VSD or PAVSD, the FMR can be chosen for the operation. The operation is relatively simple, the operation time is short and the effect is satisfactory. Existing problems include that the incidence of a third ‐degree atrioventricular block is slightly higher after the operation.
ConclusionsIn our experience, age is not a limitation of the modified single ‐patch technique, and patients even in adults with surgical indications can apply this technique. In older children and adults, we should pay more attention to atrioventricular valve annuloplasty. Infants may suffer from severe residual left atrioventricular valve regurgitation, especially in the
In this month's edition of The Journal of Thoracic and Cardiovascular Surgery, Devlin and colleagues1 present their work studying the efficacy of pulmonary artery banding (PAB) in patients with complete atrioventricular septal defect (AVSD). In an analysis of data from the Congenital Heart Surgeon's Society AVSD cohort, Devlin and colleagues1 studied 50 patients with an AVSD who underwent a PAB (median age, 1.1 months) as a staged procedure before a biventricular repair or a univentricular versus biventricular decision.
A consortium of 4 congenital heart surgery centers from Australia have reviewed their results with complete atrioventricular septal defect (CAVSD) repair and compared the outcomes of the modified single-patch and double-patch techniques.1 The authors appear to have finally settled the ongoing debate over which technique is better. The authors found no difference in survival, need for left atrioventricular valve reintervention, incidence of left ventricular outflow tract obstruction, or need for pacemaker placement.
To evaluate whether the long-term outcomes of modified-single patch (MSP) repair of complete atrioventricular septal defect (CAVSD) are equivalent to double patch (DP) repair with respect to survival and risk of reoperation for left atrioventricular valve regurgitation (LAVVR) or left ventricular outflow tract obstruction (LVOTO).

Abstract OBJECTIVE: To examine the performance of the routine 11-13 weeks scan in detecting fetal non-chromosomal abnormalities. METHODS: This was a retrospective study of prospectively collected data from 100,997 singleton pregnancies attending for a routine ultrasound examination for fetal anatomy, according to a standardized protocol, at 11-13 weeks' gestation. All continuing pregnancies had an additional scan at 18-24 weeks and 71,754 had a scan at either 30-34 or 35-37 weeks. The final diagnosis of fetal abnormalities was based on the results of postnatal examination in the case of livebirths and on the ...
ConclusionsThe specific and exclusive shape of the MVA in patients with repaired AVSD was revealed in the patients studied, resulting in a loss of the saddle shape structure. Those results could help in the comprehension of anatomic changes of the mitral valve annulus occurring after AVSD surgery.
