Calcific Plaque Modification by Acoustic Shockwaves: Intravascular Lithotripsy in Cardiovascular Interventions

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Biomedical Engineering

Background:

• Calcific plaques in coronary and peripheral vasculature are common in transcatheter interventions.
• These lesions are associated with lower procedural success, higher adverse events, and poorer long-term outcomes.

Purpose of the Study:

• To review recent literature on intravascular lithotripsy (IVL) for treating moderate-to-severe vascular calcification.
• To assess the efficacy and safety of IVL in coronary and peripheral interventions.

Main Methods:

• Literature review of studies on intravascular lithotripsy for calcified lesions.
• Analysis of procedural success, complication rates, and luminal gain.
• Assessment of plaque modification using optical coherence tomography.

Main Results:

• Intravascular lithotripsy demonstrated high procedural success rates.
• IVL showed low complication rates in managing calcified coronary and peripheral vascular beds.
• Significant luminal gain was achieved through plaque modification, as evidenced by OCT.

Conclusions:

• Intravascular lithotripsy is a promising treatment for moderate-to-severe vascular calcification.
• IVL facilitates luminal gain and stent expansion in complex calcified lesions.
• Further research is needed to define IVL's role in a structured treatment approach.
