The interventricular septum is made up of 2 parts - a membranous part and a muscular part. The membranous part is formed due to the fusion of bulbar ridges and proliferation of fused endocardial cushions as shown. Defects in such fusion lead to "VSDs" (ventricular septal defects)
Which can lead to cyanosis and ultimately death of not treated in a timely manner. The larger the defect, the louder is the murmur heard on auscultation.
