Small Ventricular Septal Defect (mVSD)

Here we present structure which reflect small ventricular septal defect (mVSD). In the model, a wall of right ventricle is segment without any other structures. mVSD refers to a minor opening in the interventricular septum, the wall that separates the left and right ventricles of the heart. Small VSDs are often referred to as restrictive VSDs, as the small size of the defect limits the amount of blood shunting between the ventricles.

In most cases, small VSDs cause minimal hemodynamic disturbance and may present with a loud murmur due to the high-velocity flow of blood through the defect. They are frequently asymptomatic and are often discovered incidentally during routine examinations. Many small VSDs close spontaneously within the first few years of life and do not require treatment.

In rare cases, if complications such as endocarditis or arrhythmias arise, or if the defect persists without closing, follow-up and possible intervention may be required. Regular monitoring with echocardiography is typically sufficient to ensure the defect does not enlarge or cause secondary problems.

The model is composed of two .STL files corresponding to right ventricle. They are of moderate size (37 MB each) and as they are pediatric models, they can be printed on the smaller 3D printer.
