Fig 1.
The scheme of conventional rotational atherectomy and halfway rotational atherectomy.
Panels (A), (B), and (C) illustrate the conventional rotational atherectomy, whereas panels (D), (E), and (F) illustrate the halfway rotational atherectomy. (A): The burr positioned just before the calcified lesion. (B): The burr ablated the proximal segment of the calcified lesion. (C): The burr ablated the full segment of the calcified lesion. (D): The burr positioned just before the calcified lesion. (E): The burr ablated the proximal segment of the calcified lesion. (F): Balloon dilatation was performed for the rest of the calcified lesion.
