Does VSD cause right ventricular hypertrophy?

Diagnosis of VSD If the VSD is large, chest x-ray shows cardiomegaly and increased pulmonary vascular markings. ECG shows right ventricular hypertrophy or combined ventricular hypertrophy and, occasionally, left atrial enlargement. ECG and chest x-ray are typically normal if the VSD is small.

Can VSD cause hypertrophic cardiomyopathy?

Hypertrophic cardiomyopathy (HCM) is a myocardial disease. However, the coexistence of HCM with muscular ventricular septal defect (VSD), especially those with both incomplete spontaneous closure and coronary abnormal origin, is relatively rare.

How does VSD affect cardiac output?

CARDIOVASCULAR EFFECTS OF VENTRICULAR SEPTAL DEFECTS A left-to-right shunt resulting from the VSD can result in: Increased LV volume load. Excessive pulmonary blood flow. Reduced systemic cardiac output.

What is the pathophysiology of VSD?

The main pathophysiologic mechanism of VSD is shunt creation between the right and left ventricles. The amount of blood shunted and the direction of the shunted blood determine the hemodynamic significance of the VSD. These factors are governed by the size, location of the VSD, and pulmonary vascular resistance.

Why does VSD cause CHF?

Children born with a VSD have a hole in the heart wall, called the septum, that separates the left and right lower chambers, called the ventricles. If the hole is large, too much blood is pumped into the lungs, making the heart work harder than normal. This may lead to congestive heart failure.

Does VSD cause tricuspid regurgitation?

Small ventricular septal defects (VSD) have high velocity flow across the defect. These can cause high velocity tricuspid regurgitation(TR) either by impinging on anterior tricuspid leaflet and richoceting as TR,1, 2 or as gerbode defect which can be mistaken as pulmonary hypertension.

What is a VSD heart murmur?

A ventricular septal defect is an abnormal opening (hole) in the heart that forms between the heart’s lower pumping chambers (ventricles), as shown in the heart on the right. This allows oxygen-rich and oxygen-poor blood to mix.

What part of the cardiac conduction system might be affected by VSD?

AV canal defects . This is the only type of VSD where serious defects of conduction occur . Interruptions can also occur in the AV node.

What would happen if there was a hole between the left and right ventricle?

This hole allows blood from the left ventricle to go back into the right ventricle instead of out of the heart through the aorta. When this happens, too much blood can enter the lungs and may cause problems over time.

Why does VSD cause respiratory infections?

In the case of a large VSD, the extra blood flow can increase the pressure in the pulmonary arteries. These are the blood vessels leading from the heart to the lungs. Over time, this can cause more lung problems.

Why does VSD cause rapid breathing?

In most cases the hole is in the membranous part of the septum; more serious VSDs are located in the muscular part of the septum. Babies with large VSDs will have excess fluid in their lungs, causing rapid and labored breathing and a fast heartbeat.
