About the condition

Heart Valve Diseases
Heart valve disease happens when one or more of your heart valves don't work well. Your heart has four valves: the tricuspid, pulmonary, mitral, and aortic valves. The valves have flaps that open and close. The flaps make sure that blood flows in the right direction through your heart and to the rest of your body. When your heart beats, the flaps open to let blood through. Between heartbeats they close to stop the blood from flowing backwards.

Strep is short for Streptococcus, a type of bacteria that often lives in your nose and throat. Most strep infections are mild, but some may become serious depending on your overall health.
