Nursing Care of Patients with Cardiac Valvular
or Inflammatory and Infectious
Cardiovascular Disorders

Stenosis
◦ Narrowed, Valve Does Not Open Completely
◦ Forward Blood Flow Hindered
◦ Decreases Cardiac Output

Regurgitation (Insufficiency)
◦ Valve Does Not Close Completely
◦ Blood Flow Backs Up



During Ventricular Systole, Mitral Valve Flaps
Normally Closed
In Mitral Valve Prolapse One/Both Flaps Bulge
Into Left Atrium
If Bulging Flaps Do Not Fit Together, Mitral
Regurgitation Occurs

