ShockFast™: Life-Saving Impact of IVL on Stent Underexpansion
We are thrilled to share a recent life-saving success using our ShockFast™ intravascular lithotripsy (IVL) system.
Patient Profile
- Age: 67-year-old female
- Medical History: Coronary artery disease (CAD) with a moderately calcified LAD lesion diagnosed via CCTA one year ago.
- Condition: Despite full medical therapy, the patient presented with exertional chest pain (CP). Transthoracic echocardiography (TTE) revealed normal left ventricular ejection fraction (LVEF).
Procedure Overview Radial angiography identified a significant calcified LAD/Diagonal bifurcation lesion.Initial treatment included aggressive dilation with high-pressure non-compliant (NC) and scoring balloons (3.0), followed by the deployment of two drug-eluting stents (DES) in the LAD. Aggressive post-dilation was performed using a 3.5 NC balloon. However, the final result was disappointing due to significant stent under-expansion.
The Game-Changer: ShockFast™ IVL Thanks to the availability of the ShockFast™ IVL system, the situation drastically changed. Using IVL, the stent was successfully expanded to a normalized pressure of 6 atm. Aggressive post-dilation was conducted thereafter, with intravascular ultrasound (IVUS) showing impressive results before and after the IVL procedure.
The patient was discharged without complications, marking another successful intervention using ShockFast™ IVL technology.
