Why the study?
Does high-speed rotational atherectomy improve the success rate of percutaneous recanalization in patients with resistant chronic total occlusions?
Does high-speed rotational atherectomy improve the success rate of percutaneous recanalization in patients with resistant chronic total occlusions?
High-speed rotational atherectomy is an effective technique for recanalizing chronic total occlusions when a guidewire crosses but a balloon catheter cannot, though it is associated with a higher rate of peri-procedural myocardial infarction.
No takes yet. Share an insight, caveat, or question.
May be considered for resistant CTOs after wire crossing; leaves open whether peri-procedural MI risk can be mitigated in prospective trials.
Pagnotta et al. (2010) studied this question.
