ECG on Instagram: "✅️Cardiac rotablation (rotational atherectomy) is a PCI technique used to modify heavily calcified coronary plaques. 🔷️A diamond-coated burr spins at very high speed to ablate rigid calcium, allowing proper stent delivery and expansion. 🔶️It doesn’t “drill a hole” — it selectively sands hard plaque while preserving elastic tissue, improving procedural success in complex calcified lesions. #Rotablation #PCI #InterventionalCardiology #CalcifiedLesions #CathLab"
