Alzheimer’s disease is a chronic progressive neurologic disorder that robs patients of their memories and ability to think. Alzheimers progression is a slow insidious process that is associated with the deposition of protein lesions or amyloid plaques in parts of the brain that are associated with memory formation and retrieval. The cost of alzheimers [...]
Interventional cardiologists (Drs. Hijazi, Kavinsky and Amin) at Rush University Medical Center ( Chicago,Il ) are performing minimally invasive nonsurgical valve replacement procedure for patients with congenital heart disease that doesn’t involve open heart surgery.
Rush is one of 3 sites participating in an investigational study of minimally-invasive pulmonary valves and successfully implanted the [...]
Survival of out of hospital cardiac arrest patients is worse on weekends than weekdays.
–Stem cells have been in the news a great deal lately and it’s because they can replace dead or damaged cells in a huge variety of locations in the human body. They can become almost any type of tissue in the body(with a few exceptions). New sources of stem cells that are easily obtained will [...]

The Ductus Arteriosus is a vascular structure that is present before birth which allows blood in the fetus to avoid going through the lungs since a fetus does not need to breathe or to have blood pass through the lungs to obtain oxygen. In most cases the Ductus Arteriosus closes within [...]
Hypoplastic left heart syndrome (also referred to as HLHS), is a congenital heart condition in which the left heart structures are excessively small or undeveloped. In the normal heart, the left side of the heart takes blood returning from the lungs and pumps it to the rest of the body. In the hypoplastic left heart [...]
In transposition of the great vessels, the aorta and pulmonary artery switch their normal positions. The aorta receives the blood from the right ventricle which does not have much oxygen, but it’s carried back to the body without passing through the lungs to receive more oxygen. Similarly, the pulmonary artery receives the high oxygen [...]
Congenital heart disease is heart disease that exists at the time of birth. Defects occur while the fetus is developing in the uterus and affect 8-10 out of every 1,000 children. Often structural defects of the heart leads to problems in pumping function and oxygenation of the blood. Rhythm problems are also associated [...]
Aortic regurgitation means that the valve between the left ventricle and the aorta (the largest blood vessel carrying oxygenated blood from the heart) is leaky. The symptoms of aortic valve regurgitation are fatigue,dyspnea, chest pain,and edema.
The causes of aortic valve regurgitation are those that develop after birth(acquired)or before birth (congenital). Congenital aortic regurgitation is often [...]
Mitral regurgitation means that the valve between the left atrium and left ventricle is leaky.
The causes of Mitral valve regurgitation are those that develop after birth(acquired)or before birth (congenital). Congenital Mitral regurgitation is fairly unusual and is usually associated with other heart abnormalities.
Some causes of acquired chronic mitral regurgitation:
Rheumatic heart disease (the body’s immune [...]
