In VSD type, the VSD is subaortic.&nbsp; <span style=\"color: #0000ff;\">Fallot type<\/span> has either a subaortic or double committed VSD and pulmonary outflow stenosis. <span style=\"color: #0000ff;\">TGA-type (Taussig-Bing)<\/span> present in new born period like transposition of great arteries. It has a subpulmonary VSD and the pulmonary artery does not arise 100% from the right ventricle. In <span style=\"color: #0000ff;\">DORV non-committed VSD or remote VSD type<\/span>, the VSD is not related to either great vessel and can extend from perimembranous region to the inlet or trabecular region. The VSD is separated by muscle of size more than the aortic diameter from the great vessels [3]. Double conus is constantly present in this type and both great vessels arise fully from the right ventricle [4].<\/p>\n<p>Eight echocardiographic types have been suggested by Pang KJ et al. The classification was based on 3 factors: the relative position of great arteries, whether it was normal or abnormal; the relationship between great arteries and the VSD, whether committed or non committed; and the presence or absence or right ventricular outflow tract obstruction [5]. They named types I, II, III and IV with subtypes A and B, making a total of 8 types. This classification was called Modified Fuwai Classification after the name of their hospital.<\/p>\n<p><span style=\"color: #0000ff;\"><strong>References<\/strong><\/span><\/p>\n<ol>\n<li>Lacour-Gayet F, Maruszewski B, Mavroudis C, Jacobs JP, Elliott MJ. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/10925219\/\">Presentation of the International Nomenclature for Congenital Heart Surgery.
