Cardiac Resynchronization with His-CRT in a patient with severe heart
failure and Scimitar syndrome.
Cardiac resynchronization therapy with His-bundle pacing (His-CRT) is
evolving rapidly as a viable cardiac device strategy for the treatment
of severe chronic heart failure. The success of this technique in
patients with congenital heart disease is facilitated by advanced
integrated imaging modalities. We report a case of His-CRT pacing for
the management of a patient with heart failure with severely reduced
ejection fraction, left bundle branch block and congenital heart disease
characterized by Scimitar syndrome with cardiac dextroposition. We
highlight the contribution of integrated imaging modalities to guide
accurate lead positioning.
