What are layman's terms for these descriptions of heart and valve function? 

Hi, Doctor. I am 63 years old and have recently had a complicated angiogram followed by echocardiogram. Would you please put into layman's terms: Normal LV with good systolic function and impaired LV relaxation. Good RV function. The aortic valve is trilunate and slightly sclerotic in appearance but not stenotic or regurgitant. Thank you and regards.

The function of the ventricles is to contract (squeeze) and relax. When they contract, the action is called systole and this is when the ventricles pump blood out. When they relax, it is called diastole and this is when the ventricles receive blood. Good systolic function and good function basically means that the muscle squeezes well. A normal aortic valve has three leaflets that open and close. An abnormal one may have two, four or only one leaflet. They are "semilunar' in appearance. This is an outdated term. Trilunate basically refers to the normal, three leaflets. Sclerotic means some calcium deposition has accumulated but not enough to adversely affect function. As we age, there is a propensity to accumulate calcium in the valves, some more and some less.
