ABSTRACT
BACKGROUND:
The aim of the study was to assess anatomical and procedural predictors of clinical and procedural failure of rotational atherectomy (RA) in an all-comers population.MethodsâandâResults:
A total of 534 consecutive patients who underwent RA were included in a double-center observational study. The primary composite endpoint consisted of rota-wire introduction failure, burr-passage failure, periprocedural complications and procedure-related major adverse events. The second primary endpoint included rota-wire introduction failure and burr-passage failure. The primary endpoint occurred in 76 (14.2%) patients and the second primary endpoint occurred in 64 (12%) Periprocedural complications occurred in 23 (4.3%) and procedure-related adverse events in 23 (4.3%) patients. Multivariable analysis revealed angulation on lesion ≤90° (HR=2.18, 95% CI 1.21-3.94, P=0.0096) and sequential lesion (HR=1.89, 95% CI 1.01-3.54, P=0.046) as independent predictors of no clinical success of RA. Multivariable analysis revealed again that angulation on lesion ≤90° (HR=2.26, 95% CI 1.16-4.40, P=0.02) and sequential lesion (HR=3.77, 95% CI 1.64-8.69, P<0.01) as independent predictors of no procedural success of RA.CONCLUSIONS:
The presence of an acute angulation on lesion and sequential lesion are independent determinants of clinical and procedural failure of RA. Further research is necessary to establish a score predicting RA failure, which can help in preproceduralrisk stratification of patients undergoing complex percutaneous coronary intervention with RA.Palabras clave
