Upgrading to VVIR biventricular pacing in a 61-year-old man with pacing-induced heart failure resulted in left-sided reversed remodeling and decreased mitral regurgitation at 6 months.

Does upgrading to VVIR biventricular pacing improve left-sided remodelling and mitral regurgitation in a patient with worsening heart failure due to VVIR pacing?
Upgrading from conventional right ventricular pacing to biventricular pacing can reverse progressive heart failure and left-sided remodelling induced by right ventricular pacing.
AIMS: 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. METHODS AND 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. CONCLUSION: 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.
A. Erol-Yilmaz (Tue,) conducted a case report in Cardiomyopathy and worsening heart failure due to VVIR pacing (n=1). Upgrading to VVIR biventricular pacing vs. Conventional VVIR pacing (prior state) was evaluated on Left sided reversed remodelling of the heart with decrease in mitral regurgitation. Upgrading to VVIR biventricular pacing in a 61-year-old man with pacing-induced heart failure resulted in left-sided reversed remodeling and decreased mitral regurgitation at 6 months.
