| Re: Right Bundle Branch Block and Mitral Valve Regurgiation. Anyone Help???
With RBBB the electrical circuit is blocked or partially blocked in the right ventricle of the heart. Usually there is a development of a bypass and in the meantime the RV may not be in sync with the left ventricle. A blocked branch bundle can be due to heart muscle damage. That would be the worst case scenario.
I have moderate/severe MVR and that or a silent MI caused heart enlargement in compensation to meet circulatory demand. There is muscle damage on the left ventricle, but medication has brought the heart back to a more normal size and the MVR may improve.
A mild MVR may not need treatment, but a test to verify there is no progression may be warranted on a periodic basis.
