Ventricular septal defect

Ventricular septal defect Ventricular septal defects (VSD) can be divided into perimembranous, muscular, inlet and outlet VSDs, depending on the location. Of these perimembranous VSDs are the commonest. VSDs can decrease in size and undergo spontaneous closure. Spontaneous closure is most likely with small muscular and perimembranous VSD, while inlet and outlet VSDs are least likely to close. Perimembranous ventricular septal defect Perimembranous VSD with perimembranous aneurysm Echocardiogram in ventricular septal defect: Parasternal long axis view shows the subaortic perimembranous ventricular septal aneurysm (marked by arrows). The color mosaic jet from the left ventricular outflow tract into the right ventricle is seen in the right panel (VSD Jet). There is a perimembranous aneurysm meaning the VSD is on the closure path. Perimembranous VSD is located in the left ventricular outflow tract and if large can involve the muscular septum in addition to the perimembranous septum. The mechanisms of spontaneous closure include: 1.       Closure by aneurysm formation 2.       Closure by prolapse of the aortic valve 3.       Closure by attachment of septal tricuspid valve 4.       Closure by ingrowth of tissue When prolapse of aortic valve occurs, there is associated aortic regurgitation which can progress over the years. Similarly, when the closure is by attachment of the septal tricuspid leaflet, there can be tricuspid regurgitation. If there is a fenestr...
