Severely calcified coronary stenosis poses a significant challenge for coronary angioplasty procedures. Modifying plaque before stenting is crucial to a successful intervention, since it will prevent the sub expansion associated to worse clinical outcomes at followup. The tools employed to assess complex lesions include specialized balloons such as cutting, scoring, or high pressure balloons, as…
ROTA.shock Outcomes: Intravascular Lithotripsy vs. Rotational Atherectomy
At present, severe calcified coronary stenosis poses a significant challenge for PCI. A successful intervention will require plaque modification prior stenting, seeing as sub-expansion has been associated with worse clinical outcomes at followup. The tools normally used to treat these complex lesions include specialized balloons such as cutting, scoring, and high pressure balloons, as well…

TCT 2018 | PREPARE-CALC: Rotational Atherectomy vs. Cutting Balloon in Calcified Lesions
Compared against conventional predilation with balloon, rotational atherectomy is associated with higher procedural success rate in severely classified lesions. Balloons capable of modifying plaque such as the Flextome Cutting Balloon or the AngioSculpt Scoring Balloon -among others- could reach similar results to that of rotational atherectomy, though this has not been tested so far. 200…
Important Study Suggests that Rotational Atherectomy Is Feasible with Transradial Access
Rotational atherectomy is a very important tool in the treatment of heavily calcified and non-dilatable lesions. Historically, transfemoral access has been the gold standard due to a perceived need for large-bore guidewire catheters in order to use spheroids for proper debulking. Nowadays, rotational atherectomy has evolved towards a technique that aims to modify plaque for…
Incidence of ‘Slow Flow’ After Rotational Atherectomy of Calcified Arteries
Courtesy of Dr. José Álvarez ‘Slow flow’ may complicate a rotational atherectomy procedure, especially when done on severely and extensively calcified lesions and small caliber vessels. Although its incidence is between 3% and 27%, its cause remains unclear, and it is thought that platelet antiaggregation induced by burr rotation speed may be behind it. …
