Background: Although the use of rotational atherectomy (RA) is off-label in the setting of ST-elevation myocardial infarction (STEMI), it can be the only option in severely calcified culprit lesions to achieve procedural success. We sought to investigate the safety and feasibility of RA during primary percutaneous coronary intervention (PPCI).
Methods: This was a retrospective observational study of patients who underwent RA during PPCI from 12 European centres.
Article Synopsis
- The study examines the prognostic significance of quantitative flow ratio (QFR) measured after successful coronary artery recanalization in predicting target-vessel failure (TVF) compared to the target-vessel SYNTAX score (tvSS).
- Out of 470 chronic total occlusion (CTO) lesions, 324 could be analyzed, revealing that lower post-procedure QFR was associated with a trend toward higher TVF rates, yet it did not significantly predict outcomes.
- In contrast, the pre-procedural tvSS was identified as a significant independent predictor for 2-year TVF, suggesting its importance over immediate QFR assessment for long-term prognosis.
Background: With the established use of crossover stenting technique in bifurcation coronary artery lesions, added clinical benefit of final kissing of the side branch remains debatable. We report a case of a stenosis and thrombus formation of an ostial side branch after crossover stenting. A 38-year-old man was admitted with acute coronary syndrome complicated by acute pulmonary oedema.
