Leptitox The heart has 4 chambers including 2 atrial chambers involving the right chamber and left chamber and 2 ventricular chambers containing the right ventricle and left ventricle. These 4 heart chambers have their different limits in siphoning and getting blood. Ventricular Septum Defect Abnormalities happen on account of an opening that causes spillage that occurs between the left ventricle and right ventricle. http://www.eatasialondon.com/
