Objective:

To describe the use of a dual-balloon overlapping post-dilation technique for optimal stent expansion in a severely dilated right coronary artery, particularly in cases where conventional methods have failed.

Key Findings:
  • Initial post-dilation showed significant malapposition with MSA at 4.8 mm2, indicating underexpansion.
  • DBOPD improved MSA to 7.6 mm2 with complete strut apposition, demonstrating the technique's effectiveness.
  • IVUS confirmed no edge dissection or vessel injury after DBOPD, ensuring patient safety.
Interpretation:

The DBOPD technique effectively addresses stent malapposition in ectatic coronary segments, providing a viable option when conventional methods are inadequate and highlighting its innovative approach.

Limitations:
  • Potential risk of coronary perforation with high-pressure post-dilation, necessitating careful monitoring.
  • Long-term effects on stent integrity after significant overexpansion remain unknown, which could impact future patient outcomes.
Conclusion:

DBOPD is a promising salvage technique for achieving stent apposition in challenging cases, but should be used cautiously, with thorough monitoring to mitigate associated risks.
