Coronary artery compression/damage by cardiac pacing/defibrillation leads is very rare and often an unknown complication of pacemaker implantation. Here, we present the case of a 71-year-old woman with late discovery of an asymptomatic compression of the left anterior descending (LAD) coronary artery by a defibrillation lead implanted ten years before. This dissuaded us in removing this now malfunctioning lead with high threshold, and an additional right ventricular (RV) lead was implanted along with atrial and left ventricular (LV) leads for allowing resynchronization therapy.

- Complete bidirectional cavo-tricuspid isthmus (CTI) block is essential for successful radio-frequency (RF) ablation of typical atrial flutter, and this can be evaluated using a simplified technique with two catheters and differential pacing.
- In a study of 255 patients, the technique achieved an 80% procedural success rate, with a recurrence of atrial flutter seen in 14% of patients over about 15 months.
- The study concluded that this simplified differential pacing method shows long-term results comparable to more complex techniques, making it a cost-effective option for AF procedures.
