rotational atherectomy
Percutaneous technique using high-speed rotational cutting to modify calcified coronary lesions.
Full Definition
A specialized percutaneous coronary intervention technique that employs a diamond-coated rotating burr to ablate calcified plaque and modify heavily calcified coronary lesions. Rotational atherectomy is typically reserved for lesions that cannot be adequately dilated with conventional balloon angioplasty due to severe calcification. The procedure facilitates subsequent stent deployment by creating microscopic debris that can be safely absorbed by the reticuloendothelial system.
Usage
Usage note: May be abbreviated as ROTA; specify burr size when documenting.
