2025年2月17日 · VSD types. There are four main types of ventricular septal defects. They differ in their location and the structure of the hole (or holes). The types of VSDs are: Membranous. This is the most common type of VSD. These VSDs happen in the upper section of the wall between your ventricles. Muscular. These happen in the lower part of the wall.

2024年10月16日 · Ventricular septal defects (VSDs) are the most prevalent congenital cardiac anomaly in children and the second most common heart defect in adults, after bicuspid aortic valves. The primary mechanism in hemodynamic compromise in VSDs arises from abnormal communication between the right and left ventricles, leading to shunt formation.

2024年11月7日 · Ventricular septal defects (VSD) represent a hole or pathway in the interventricular septum that allows for communication between the right and left ventricles. It typically results in a left-to-right shunt. They represent one of the most common congenital cardiac anomalies and may be associated with up to 40% of such anomalies 1.

2006年11月14日 · Ventricular septal defect (VSD) is a common congenital heart defect in both children and adults. Management of this lesion has changed dramatically in the last 50 years. Catheter-based therapy for VSD closure, now in the clinical trial phase, is another step in the evolution of treatment for this disorder.

A ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle.

2024年10月19日 · A ventricular septal defect (VSD) happens during pregnancy if the wall that forms between the two ventricles does not fully develop. This leaves a hole. In babies without a heart defect, the right side of the heart pumps oxygen-poor blood from the heart to the lungs.

There are four categories of VSDs named based on the anatomical position. We will describe the main types of VSDs and focus on imaging for membranous VSDs. Membranous (perimembranous, subaortic, conoventricular): Membranous VSDs are the most common type of VSD, comprising 75-80% of all defects (2).

AV canal type VSDs lie in the inlet septum, beneath and adjacent to the tricuspid valve. This type of VSD is present in a complete AV canal defect, but can also occur in hearts without a complete canal defect, for example with a straddling tricuspid valve. Muscular VSDs occur in the muscular septum, so that their rim is entirely made up of muscle.

2024年3月5日 · A ventricular septal defect (VSD) is a congenital defect in which there's a hole in the heart's wall. One of the most telling symptoms of VSD is a heart murmur, which often becomes evident a few days after birth. Read about diagnosis, symptoms, prognosis, complications, and treatment.

VSD is an opening or hole (defect) in the wall (septum) separating the two lower chambers of the heart (ventricles). In normal development, the wall between the chambers closes before the fetus is born, so that by birth, oxygen-rich blood is kept from mixing with the oxygen-poor blood.
