Reversed remodelling of dilated left sided cardiomyopathy after upgrading from VVIR to VVIR biventricular pacing.
OBJECTIVE
To show reversed remodelling of the left ventricle and left atrium after upgrading to biventricular pacing in a patient with worsening heart failure due to VVIR pacing. To review the literature concerning reversed remodelling after upgrading to biventricular pacing.


RESULTS
In a 61-year-old man, with cardiomyopathy and worsening heart failure and mitral insufficiency following conventional pacing after His-bundle ablation, upgrading to biventricular pacing showed left sided reversed remodelling of the heart with decrease in mitral regurgitation in 6 months. The literature is reviewed by a Medline search between 1966-2001.


CONCLUSIONS
The occasionally observed progressive heart failure after right ventricular pacing following His-bundle ablation can be reversed by upgrading to VVIR biventricular pacing and under these circumstances upgrading should be considered.
