Aims and objectives: To assess effect of single chamber right ventricular pacing on function of atrio-ventricular valve at 1 year of prospective of follow up.  Methods and Results: A total of 135 patients having atrio-ventricular disease received single chamber pacemaker implantation were enrolled. Study outcomes were changes in the function of atrio- ventricular valve. During 1 year of follow up proportion of moderate MR was similar but proportion of severe MR was significantly reduced to 0.0% (p=0.03) and proportion of moderate and severe TR was not changed but proportion of mild TR was increased 35.7% from baseline to 53.1% at 12 month but statistically not significant (p=0.84) Conclusions:  Right ventricle apex pacing lead was not affect tricuspid regurgitation significantly. None of the patients were developed  right  side  heart failure.
