A subset of the primary tumors of the heart are tumors that are found on the valves of the heart. Tumors that affect the valves of the heart are found in an equal distribution among the four heart valves. [2] The vast majority of these are papillary fibroelastomas. Primary tumors of the valves of the heart are more likely to occur in males.
A myxoma is a rare benign tumor of the heart. Myxomata are the most common primary cardiac tumor in adults, and are most commonly found within the left atrium near the valve of the fossa ovalis. Myxoma may also develop in the other heart chambers. [1] The tumor is derived from multipotent mesenchymal cells. [1]
A papillary fibroelastoma is a primary tumor of the heart that typically involves one of the heart valves. [1] Papillary fibroelastomas, while considered uncommon, make up about 10 percent of all primary tumors of the heart. [2] They are the third most common type of primary tumor of the heart, [3] behind cardiac myxomas and cardiac lipomas.
Most heart tumors begin with myxomas, fibromas, rhabdomyomas, and hamartomas, although malignant sarcomas (such as angiosarcoma or cardiac sarcoma) have been known to occur. In a study of 12,487 autopsies performed in Hong Kong seven cardiac tumors were found, most of which were benign. [ 1 ]
Heyde's syndrome; A stenotic aortic valve: Specialty: Cardiology, general surgery, Hematology: Symptoms: Aortic valve stenosis symptoms: Chest pain (angina) or tightness Shortness of breath, especially during exertion or when lying down Fatigue or weakness Irregular heartbeat or heart palpitations Dizziness or fainting episodes Gastrointestinal bleeding symptoms: Occult (hidden) or overt ...
Fetal heart surgery. To remove the tumor from the baby’s heart, doctors take the baby’s chest and arms from the uterus essentially “sneaking in without the placenta and uterus knowing we ...
The left side of the heart is more muscular than the right side of the heart. It pumps oxygenated blood from the lungs into the aorta to perfuse the rest of the body. [ 4 ] When the heart has to pump against increased resistance, or afterload , as in the case of a ventricular obstruction, it compensates by growing in size.
The microvascular dysfunctions refer to the abnormalities in the very small blood vessels of the heart. The narrowing of these vessels may lead to lack of oxygen in specific areas of the cardiac muscle causing chest pain. Several studies have shown that patients living with microvascular angina may have an enhanced pain perception, and usually ...
