Heart valves can be damaged in two ways: the valve tissue stiffens and doesn't open properly, or the valve becomes leaky, allowing blood to flow in both directions.
Le valvole cardiache possono danneggiarsi facendo in modo che il tessuto valvolare si irrigidisca e non si apra correttamente, oppure diventando così lese da permettere al sangue di fluire in entrambe le direzioni.
