Coarctation of the aorta

Narrowing of aorta; less blood to lower body

Cardiomyopathy

Any disorder that effects the heart muscle

Congestive heart failure (CHF)

The heart is unable to pump enough blood; results in pulmonary edema; fatal if untreated

Coronary artery disease

Narrowing or coronary arteries; not enough blood to heart

Fibrillation

Quiver of either the atrium or ventricle; not effectively pumping blood

Essential hypertension

High blood pressure that is not due to any other condition

Flutter

A regular beat of the heart but it is at a rapid pace

Hypertensive heart disease

Changes to the heart due to chronic high blood pressure

Infarction

Tissue death due to not enough blood flow (basically a heart attack)

Mitral valve prolapse

Improper closure of the mitral valve

Tetralogy of Fallot

Ventricular septal defect; pulmonary stenosis; ventricular hypertrophy; shift of aorta

Patent Ductus Arteriosus

Ductus arteriosus doesn't close after birth; blood from aorta flows into pulmonary artery

Myocardial Infarction

Heart attack; blockage of bloodflow to heart muscle

Deep Vein throbosis

a condition where a blood clot forms in a vein deep within the body; usually in legs

endocarditis

a life-threatening inflammation of the inner lining of the heart's chambers and valves

Peripheral vascular disease

A circulatory condition in which narrowed blood vessels reduce blood flow to the limbs

rheumatic heart disease

a condition where the heart valves have been permanently damaged by strep or scarlet fever

Septal defects

A heart defect due to an abnormal connection between the lower chambers of the heart

Varicose veins

swollen, twisted vein that lie just under the skin
