Ventriculo-atrial gradient due to first degree atrio-ventricular block: a case report
Key result
Dual-chamber pacemaker implantation with optimal restoration of AV synchrony improved symptoms from NYHA class III to II and reduced pulmonary artery systolic pressure from 38 to 28 mmHg.
Why the study?
Does permanent pacemaker implantation improve symptoms and echocardiographic parameters in a patient with marked first-degree AV block and heart failure?
Population
1 72-year-old woman with marked first-degree AV block, moderate aortic stenosis, and NYHA class III symptoms…

P
Population
A 72-year-old woman with marked first-degree AV block, moderate aortic stenosis, and NYHA class III symptoms of heart failure.
I
Intervention
Permanent pacemaker implantation with physiological AV delay
O
Outcome
Improvement in echocardiographic parameters and symptoms of heart failuresurrogate
Dual-chamber pacing to restore AV synchrony may be a beneficial therapeutic option for patients with marked first-degree AV block and heart failure symptoms.
Limitations
- Single case report
- Short follow-up duration of 2 days for echocardiographic evaluation
Cite This Study
Andò et al. (2005) conducted a case report in First degree atrio-ventricular block and moderate aortic stenosis with heart failure (n=1). Dual-chamber permanent pacemaker implantation vs. Baseline (pre-implantation) was evaluated on Echocardiographic parameters and heart failure symptoms. Dual-chamber pacemaker implantation with optimal restoration of AV synchrony improved symptoms from NYHA class III to II and reduced pulmonary artery systolic pressure from 38 to 28 mmHg.
