Background: Stent underexpansion is the most powerful predictor of long-term stent patency and clinical outcome. The purpose of this study was to evaluate the incidence and predictors of stent underexpansion despite adjunctive post-dilatation with non-compliant balloon.
Methods: After elective coronary stent implantation and adjunctive post-dilatation with non-compliant balloon and optimal angiographic result confirmed by the operator, intravascular ultrasound (IVUS) was performed for all the treated lesions.
Intracardiac atrial signal amplitude in congenital and acquired complete heart block.

Article Synopsis
- Reliable atrial sensing is crucial for AV synchrony in dual chamber pacemakers, with VDD models more susceptible to atrial under-sensing compared to DDD models.
- A study involving 34 patients with congenital and acquired complete heart block measured intracardiac atrial signal amplitudes (IASA) at implantation and during follow-up to compare the two groups.
- Results showed that patients with congenital heart block had significantly higher IASA levels at implantation and during follow-up, suggesting the chronicity type of heart block may influence VDD pacemaker implantation decisions.
