2024年10月16日 · Characteristics: Infundibular VSD, also referred to as supracristal, is a rare VSD type that accounts for only 6% of all cases but occurs in about 30% of the Asian population. Aortic valve prolapse and regurgitation frequently develop due to inadequate support for the right and noncoronary cusps of the aortic valve.

2006年11月14日 · Defects in the infundibulum are called infundibular, outlet, supracristal, conal, conoventricular, subpulmonary, or doubly committed subarterial defects. A deficient infundibular septum may be present with corresponding degrees of malalignment. All defects should be assessed for location, size, and multiplicity.

1997年3月4日 · Such defects result in a communication between the apex of the LV and the infundibular apex and have been termed LV-infundibular apical VSDs. The prevalence of LV-infundibular apical VSD among 274 consecutive patients with muscular VSD was 7.3%. This type of defect made up 43% of apical VSDs.

2020年11月10日 · The ventriculinfundibular fold is a muscular fold or inner heart curvature that separates an arterial from an atrioventricular valve at the base of the ventricles. 14, 15 When it is present, as in a normal right ventricle, it completes the …

A ventricular septal defect (VSD) is an integral part of most congenital heart defects (CHD). To determine the prevalence of VSD in various types of CHD and the distribution of their anatomic types. We reviewed 1178 heart specimens with CHD from the ...

Ventricular septal defect (VSD) — also known as a “hole in the heart” — is a congenital heart defect. It involves a hole in the wall between the heart’s lower chambers. Ventricular septal defects can be further described by; 1) Size of the defect, 2) Location of the defect, 3) Whether there is more than one defect present,

2019年7月7日 · Infundibular VSD (<5%, also called outlet, supracristal, choanal, conoventricular, subpulmonary, or doubly committed subarterial defects ): located in the infundibular muscular septum, which is the portion of the septum separating the right and left ventricular outflow tracts.

2023年2月7日 · Ventricular septal defect (VSD) is one of the most common congenital heart defects (second only to bicuspid aortic valve), but accounts for only 10 percent of congenital heart defects in adults because many close spontaneously . VSDs are of various sizes and locations and can be single or multiple.

Anatomically, the ventricular septum can be divided into four regions based on the anterior and posterior extension of the septomarginal trabecularis. These include the inlet septum, trabecular septum, outlet or infundibular septa, and the membranous septum.

1997年3月4日 · Left ventricular-infundibular apical VSDs constitute a distinct morphological type of muscular VSD that can be distinguished by echocardiography and cineangiography. In selected cases, the infundibular apex can be separated from the rest of the right ventricular inflow and outflow to eliminate flow …
