Direct Stenting via 5F Diagnostic Catheter

Case Overview

This 58 year old patient presented with stable angina. Coronary angiography was performed using 5F Cordis Infinity diagnostic catheters (0.047″ ID). During the left coronary angiogram, using a JL4 catheter, a significant stenosis was diagnosed in the proximal ramus. (A)

Procedural Progression

The decision was made to immediately direct stent the proximal ramus via 5F diagnostic JL 4 catheter already in place using the Svelte IDS (3.0 mm diameter, 13 mm length).

After introducing the Svelte IDS into the Dx catheter, the system was successfully advanced and properly positioned across the lesion using the radiopaque markers for guidance. (B) The Svelte stent was successfully deployed at high-ATM inflation. (C)

Control angio revealed an optimal result (D) with a step up proximal to the stent that disappeared after intracoronary injection of nitroglycerine.

Conclusion

This procedure shows the versatility of the Svelte IDS delivered through a 5F (0.047″ ID) diagnostic catheter. This stenting procedure was completed in quick fashion and using a limited amount of ancillary devices. By using a Dx catheter, substantial savings were realized in material used (guiding catheter, guidewire, pre- and/or post dilation balloon, contrast) and overall procedure time. The stenting procedure was completed in 1 min, 6 sec.

Keys to Success: 

  • Low profile for use with a 5F Dx catheter (0.047″ ID)
  • An ‘All-in-One’ device obviates the need to introduce any other devices
The success that has been achieved in our lab stenting through Dx catheters further validates the clinical and practical benefits of the Svelte ‘All-In-One’ IDS.
