I have a leaking heart valve and the doctors are waiting until they think I need a replacement. Meanwhile I have an episode of a.f. which takes me to a&e about every 9-12 months. Other times I manage to tough it out until the heart goes back into normal rhythm. Still there are days when I just feel queer. Only on dabigatran as cardiologist said I haven't had any benefit from previous drugs. Glad to be almost medication free. Will I feel better and with less a.f. episodes after a valve replacement? I had a ventricular standstill last December when in hospital. Any thoughts out there please?
