AB Valvular  heart  disease  may  remain  asymptomatic  until  an  underlying  serious  illness  causes  rapid  deterioration  of  health.Patients  with  valvular  heart  disease  are  at  increased  risk  of  bacterial  endocarditis  following  invasive  procedures.Aortic  stenosis  significantly  increases  the  mortality  of  patients  requiring  noncardiac  surgery.Aortic  stenosis  is  a  common  comorbidity  in  elderly  patients.Heart  failure  in  a  patient  with  hypertrophic  cardiomyopathy  should  be  treated  with  rate-slowing  and  negative  inotropic  agents.Acute  regurgitant  lesions  are  frequently  medical  emergencies  and  are  not  as  well  tolerated  as  chronic  regurgitant  lesions.Once  left  ventricular  dysfunction  occurs  in  a  patient  with  mitral  regurgitation,  the  lesion  is  severe  and  unlikely  to  improve  with  surgical  correction;  in  fact,  surgery  may  worsen  left  ventricular  function.
