After heart valve surgery, it is crucial to avoid infections to maintain health. Accordingly, taking protective measures such as flu and pneumonia vaccines, as advised by a doctor, is recommended. In case of any infection symptoms, contact a doctor immediately and consult about protective antibiotic treatment if deemed necessary. Patients' frequent pre-operative concerns about 'my health deteriorating after surgery' are unfounded. Following a successful operation, patients generally achieve a higher quality and more active life; therefore, there is no need for such anxieties.
