Cardiac Catheterization is a medical procedure where in a long, thin, flexible tube(Catheter) is inserted into a blood vessel in the arm, neck or upper thigh and threaded into the heart. Prior to this, a local anaesthesia is given to numb that particular area where a small puncture is made for the entry of a…
Human heart is composed of four chambers(two atria and two ventricles) which are separated by walls between them. The presence of a defect in the wall dividing the two ventricles results in the ventricular septal defect. Although VSD is the most common congenital heart disease accounting for the 20 – 25%, it can also be…
Veins are blood vessels in our body which conduct blood from peripheral tissues in the body to heart. These vessels, unlike the arteries, lack a muscular wall and depend on the surrounding muscles to pump blood to heart in an antigravity direction. When there is immobilisation for a long duration, there can be stasis of…
Aorta is the great blood vessel, the largest in the body, which receives blood from the heart to circulate to different parts of the body. Aorta can be involved in many disease conditions – the important ones are: Aortic Aneurysm Aortic Dissection Aortitis Aortic Aneurysm Aortic aneurysm involves the abnormal dilatation of the aortic wall.…
Heart pumps blood oxygenated from the lungs to different tissues of body. The oxygen supplied through the blood is necessary for the proper growth and functioning of the tissues. If blood flow is stopped at normal body temperature, permanent brain damage normally occurs in three to four minutes — death may follow shortly afterward. During…
An artificial heart is a mechanical device that is implanted into the body to takeover the function of a failing heart. A synthetic replacement for the heart remains one of the long-sought goals of the modern day science. An artificial heart is distinct from a heart lung machine which operates from the exterior and can…
Ischemic Cardiomyopathy is a heart muscle related disease caused due to the insufficient supply of oxygen and blood. This can lead to Congestive Heart Failure(heart attack). The defect arises due to the enlargement and dilation of the left ventricle and hence reducing the heart’s ability to ability to pump blood. It is seen that, in…
Mitral valve prolapse is a disease that affects the mitral valve of the heart. In it’s normal operation the mitral valve controls the flow of blood between the two left chambers of the heart viz. the left atria and the left ventricle and it prevents any backflow of blood. Sometimes the valve doesn’t function properly.…
The Mitral valve also known as the bicuspid valve or left atrioventricular valve is a heart valve which regulates the flow of blood between the two left chambers of the heart. It controls the flow of blood from the left atrium to the left ventricle of the heart and prevents the flow in the opposite…
Hypertrophic Cardiomyopathy is a condition of the heart in which a part of the myocardium or the muscle of the heart is enlarged without any obvious reasons. It is very common and affects people of all ages. It is the most common cause of sudden cardiac death in young people and affects both men and…
