Key result
Examination of the extracted specimen from salvage directional coronary atherectomy revealed predominantly atheromatous tissue with minimal thrombus, contrary to the presumed intracoronary thrombus.

Atherectomy tissue retrieval can identify the true etiology of acute vessel closure following balloon angioplasty, which may differ from angiographic presumptions.

Angiographic thrombus presumption may be inaccurate in post-angioplasty closure; leaves open whether atherectomy tissue analysis improves diagnosis.
Directional coronary atherectomy was successfully performed in the mid-left anterior descending artery at the site of failed balloon angioplasty. We presumed that intracoronary thrombus had resulted in acute vessel closure following balloon angioplasty, due to the angiographic appearance of the lesion and the clinical situation. However, examination of the extracted specimen from the atherectomy device revealed predominantly atheromatous tissue with minimal thrombus.

Mayeda et al. (1996) conducted a case report in Acute vessel closure following balloon angioplasty (n=1). Directional coronary atherectomy was evaluated on Histological examination of extracted specimen. Examination of the extracted specimen from salvage directional coronary atherectomy revealed predominantly atheromatous tissue with minimal thrombus, contrary to the presumed intracoronary thrombus.
