Patient History

  • ISR in the RCA
  • FFR: 0.78
  • Inferior ischemia on Cardiolite®1

Baseline Angiography

Baseline angiography of RCA

Pre-PCI HD IVUS (1)

  • Following baseline HD IVUS guidance, a 1st pre-PCI balloon dilation is performed using 3.5 mm X 6.0 mm cutting balloon at 12 ATM.
  • This is followed by 2nd pre-PCI balloon dilation using 4.0 mm × 12.00 mm NC Emerge™ PTCA Dilation Catheter2 at 28 ATM.
  • HD IVUS measurements of proximal and mid-lesion are taken after 1st and 2nd pre-PCI balloon dilations.

Pre-PCI Angiography

A laser atherectomy is used followed by 4.0 mm x 12.0 mm NC Emerge™ PTCA Dilation Catheter2.

Post-PCI Angiography

RCA is stented using 3.5 mm X 28.0 mm Promus PREMIER™ Everolimus-Eluting Platinum Chromium Coronary Stent3. This is followed by post-stent dilation using a 4.0 mm X 12.0 mm NC Emerge™ PTCA Dilation Catheter2.

Conclusion

HD IVUS reveals the ISR within the RCA, helped with sizing of RCA, revealed the success of balloon dilations, atherectomy, facilitating an optimal PCI result.
