Improving Atherectomy Outcomes With IVUS Catheter Imaging
Atherectomy is a technique used to remove plaque from arterial walls, and its success depends greatly on understanding lesion characteristics. IVUS catheters provide the clarity needed to navigate these procedures safely and effectively. By showing plaque thickness, distribution, and composition, IVUS helps clinicians decide whether atherectomy is appropriate and how to approach the lesion.
Before atherectomy begins, IVUS imaging outlines the extent of calcification and plaque shape. This is important because rotational or orbital atherectomy devices perform differently based on plaque density. Deep calcified lesions, for example, may require more passes or different device settings. IVUS images allow clinicians to predict procedural challenges and plan accordingly.
During atherectomy, IVUS helps in monitoring progress. After an initial pass, clinicians may re-image the vessel to see whether further plaque modification is necessary. This iterative process ensures plaque is removed without damaging underlying tissue. It also reduces the need for excessive tool deployment, lowering the risk of complications.
After plaque modification, IVUS confirms whether the vessel is ready for balloon inflation or stent placement. This step is vital because insufficient plaque removal may hinder stent expansion or cause future restenosis. By validating results immediately, IVUS supports safer and more effective interventions.
IVUS-guided atherectomy leads to fewer complications, improved stent performance, and better long-term vessel patency. As lesion complexity increases in modern cardiovascular care, IVUS becomes indispensable for guiding plaque-removal strategies with precision.
