WHat causes hole in the heart?
3 ANSWERS

There are two  sorts of non-traumatic “holes” (not caused by injury): each involve the walls between the “right side” and therefore the “left side” of the center. all sides has 2 chambers: the higher one, that receives deoxygenated blood from the body (Right Atrium) or freshly ventilated blood from the lungs (Left Atrium), and therefore the lower one, that receives blood from the higher through a unidirectional valve and discharges it to the lungs for re-oxygenation (Right Ventricle) or dead set the body (Left Ventricle, the stronger one) through the arterial blood vessel. These walls area unit referred to as the chamber septum, and unremarkably forestall deoxygenated blood from the body from admixture with freshly ventilated blood from the lungs.

However, there's just once in life wherever it's necessary that blood getting into the correct Atrium be sent on to the left facet of the center for distribution to the body: before birth, once the lungs don't seem to be nonetheless purposeful and every one ventilated blood is returning from the placenta. to permit this, everybody ab initio features a hole between the 2 higher chambers, protected by a flap to stop reverse flow, to permit ventilated blood to cross straightaway to the left facet of the center, bypassing the lungs. At birth, once chemical element becomes accessible from the lungs, the pressure within the atrium of the heart exceeds that within the atrium dextrum, closing the flap between them. In some cases, however, the flap doesn’t properly or totally shut, permitting blood to leak from the atrium of the heart to the correct Atrium, or permitting blood clots (from the leg, for example) to travel from the correct to the left facet of the center then out into the body, wherever they'll cause severe harm sort of a stroke. This persistent “hole” between the atria is named associate chamber congenital heart defect, or ASD.

The septum, or wall, between the 2 ventricles unremarkably forms utterly throughout development of the center, growing from the apex of the center (point) toward the higher septum, however generally fails to totally kind, leading to a persistent hole between the correct and Left Ventricles. this is often referred to as a bodily cavity congenital heart defect, or VSD, and is sort of invariably problematic as a result of ventilated blood that ought to effuse to the body is instead forced through the VSD into the correct Ventricle, wherever it needlessly circulates back to the lungs. as a result of this drawback develops before birth and will lead to short chemical element reaching the body, the consequence is also a “blue” baby, however generally the matter isn’t evident till the kid develops a lot of.

The hole in the heart is a cardiac disorder called patent Foramen ovale (FOP). It is a congenital defect in the septum (wall) between the two upper chambers (atria) of the heart that occurs due to an incomplete closure of the atrial septum. The defect creates a flap or valve-like opening in the atrial septum wall. In simple terms, it is a hole in the heart that does not close as it should after birth. The hole in the heart is a congenital anomaly. In the anomaly, the septum between the two atria of the heart normally developed before birth, but the flap was not completely sealed after birth. The exact reason behind the defect is unknown. Sometimes, it can be a viral infection that can cause heart defects. There may be genetic factors, some medical conditions (such as Down's syndrome), medical prescriptions and over-the-counter drugs.

Mostly that happens if .... your loved one is having relationship with other person :) Or if someone shots you through the heart :)  Just joking.  In reality, every heart has a lot of "holes". Hearts are a kind of pumps, pumping your blood through the veins, and enabling your organism to function.
