An ventricular septal defect is a hole between the two ventricles of the heart. Normally this hole is present at birth but closes within a few days of life. Failure of this hole to close is called a ventricular septal defect, and usually is asymptomatic (no obvious symptoms are present). Created by Leslie Samuel.

I had a patient with this disorder and this really clears up the understanding of the pathophysiology. Thanks a bunch!

The L to R shunt results when the pulmonary resistance is low. However, increased amounts of blood flowing into the R ventricle are pumped to the pulmonary circulation, eventually causing an increase in pulmonary resistance, which then leads to increased pulmonary vascular resistance, causing pulmonary HTN and R ventricular hypertrophy. The effect is a R to L shunting of blood across the VSD. This can lead HF, pulmonary HTN, cyanosis, and the risk for development of aortic valve regurgitation and potential endocarditis. Is this the case if the hole in the septum is not repaired or doesn't heal spontaneously? I'm a little confused (though I love your presentation! It's very helpful and gives an excellent visual) because I'm currently studying this for nursing school and our pediatrics text book makes it sound a bit more complicated.Thanks.

Hello and Happy New Year of 2015 this will be the 59th anniversary of my ground breaking open heart surgery for VSD. I was 15 months old and was only given a 50-50 chance of survival and I will be 60 in May!

I know this is a (very) old comment, but why did you need surgery? I had this and the doctor shrugged it off like it was no problem. I actually still have it, and it still isn't a problem. (I actually have 3 defects in my heart currently, but none of them are a problem.)

I once saw a site full of CHD diagrams(congenital heart defects) and on that site, I saw a diagram of Single Ventricle Syndrome, basically a VSD, but so extreme that there’s either no interventricular septum or the little bit that’s there doesn’t separate the 2 ventricles.

In 1964, I was 3 1/2 yrs old. I had open heart surgery for this defect and have a deformed mitral valve. today I am 55 yrs old. My surgery was in Chicago IL.

Your testimony is very encouraging to me be it that my son has a Partial AV Canal which is a mix of the two videos he did here. Although my son's defect is a bit more severe or unique (as the doctors like to say) than just a regular Partial AV, your testimony gives me hope. His condition is similar to a Complete AV canal, but isnt a complete AV canal. Its when a hole is present in the septum between the ventricles(this video) and a hole also in Septum between the left and right atrial. Thus, atrioventricular canal. Atrio-ventricular canal. The gap or hole between my sons Ventricle is somewhat formed, but not fully formed. The doctors are saying the problem wont be the gaps or holes, those are easy to fix...the hard part will be the leaky valves my son has. These are very fragile and be it he is only just over 2 weeks old they need him to grow a lot in order to perform the surgery with the highest outcome of success. Just wanted to say thank you for your story you shared here, even though my son's case is a bit different than yours, it brings me comfort to hear yours. So, I thank you.

@hiwotworkneh5101 4 жыл бұрын

Does the condition progresses if not treated with surgery? what if the shunt is bidirectional can it still be corrected with surgery?

@matthewravi5782 3 жыл бұрын

why it cannot be right to left shunt by any chance, since the hole is there? Is it due to the force of the venous deoxygenated blood that is much less than the force of the arterial oxygenated blood?

Why, in VSD, heart failure occures in left ventricle first???If LV get volume overload, it can push blood to RV via L-R shunt and RV must get this overload..can anyone explain it for me?..thanks so much :)

@yarahazemgsf8902 9 жыл бұрын

Phuc TranI think because the opening between the two ventricles is not very big to transmit the same pressure from left to right

@22inominata 9 жыл бұрын

Phuc Tran when the pressure in the RV increases due to the left to right shunting of blood, it will cause pulmonary hypertension. At the end, when the pulmonary resistance becomes higher than systemic resistance, it causes right to left shunting of blood. At this stage, the condition is called as eisenmenger complex.

@JuicyCharon 9 жыл бұрын

anna inominata Thanks for that. I've tried to understand eisenmenger's syndrome for a while now and it's just clicked when I read your post.
