Heart Valve Voice Heart Valve Voice is the UK’s dedicated heart valve disease charity. We work with patients and clinicians to help increase the awareness of heart valve disease in the UK and improve diagnosis and treatment. Heart valve disease affects over 1.5 million people over the age of 65 in the UK and our aim is to ensure that more of the population is aware of the importance of having their heart checked for heart valve disease, which can often be detected through a simple stethoscope check.
