We report the case of a 74-year-old man having angioplasty following admission with a troponin positive acute coronary syndrome. Due to heavy coronary artery calcification, rotablation was used. The procedure was complicated by a stuck burr ("Kokeshi phenomenon"). We employed a novel method to safely remove the burr and complete the procedure. < Various methods have been described for the retrieval of an entrapped Rotablator burr; we show in this case that deep engagement of guiding catheter and manual traction is a safe and effective method for retrieval.>.

Unlabelled: Intervention to proximal lesions should be avoided in graft-protected native coronary arteries in general, because there might be a risk for bypass-graft failure. An 81-year-old man with coronary artery bypass grafting surgery due to 3-vessel disease 17 years previously complained of worsening angina. Coronary angiography (CAG) revealed a diseased saphenous vein graft (SVG) and a probable functional occlusion in the mid left anterior descending coronary artery (LAD) concomitant with calcified severe stenosis in the left main (LM)-proximal LAD, and patent right internal thoracic artery (RITA)-LAD graft.

Objectives: We aim to describe the step-by-step optical coherence tomography-guided rotational atherectomy and intravascular lithotripsy for treating substantial coronary calcified nodules.

Key Steps: These include initial rotational atherectomy with a 1.5-mm burr, multiple optical coherence tomography imaging studies to assess lesion morphology, upsizing the rotational burr to 2.

Background: Rotational atherectomy (RA) remains an integral tool for the treatment of severe coronary calcified lesions despite emergence of newer techniques. We aimed to evaluate the contemporary clinical practices and outcomes of RA in China.

Methods: The Rota China Registry (NCT03806621) was an investigator-initiated, prospective, multicenter registry based on China Rota Elite Group.

Article Synopsis
  • Intravascular lithotripsy (IVL) combined with rotational atherectomy (RA), referred to as Rotatripsy, is used to treat severe coronary artery calcification (CAC), but data on its effectiveness and safety over time is limited.
  • A study included 114 patients across six centers, showing high device (97%) and procedural (93%) success rates, with some minor complications reported.
  • At the 1-year follow-up, only 9% of patients experienced major adverse cardiovascular events (MACE), indicating that Rotatripsy is safe and effective, with RA typically used before IVL in treatments.
