Objective: To investigate the safety and efficacy of rotational atherectomy in the interventional treatment of coronary chronic total occlusion lesions. Methods: In this retrospective study,a total of 31 consecutive patients with coronary chronic total occlusion(CTO) lesions underwent rotational atherectomy in our hospital from February 2004 to December 2016 were enrolled,and the clinical features were analyzed. Coronary atherectomy was performed if balloon failed to cross the CTO lesions or balloon could not be fully dilated in the CTO lesions after wire crossing...

Introduction: Most established risk factors after rotational atherectomy (RA) of heavily fibro-calcified lesions are associated with patients' general risk and clinical related factors and are not specific for either coronary and culprit lesion anatomy or the RA procedure. Aim: To assess novel predictors of poor outcome after percutaneous coronary intervention using RA in an all-comers population. Material and methods: A total of 207 consecutive patients after RA were included in a single-center observational study...

We report a novel technique for retrieving an entrapped Gaia guidewires in severely calcified coronary chronic total occlusion (CTO) using a rotational atherectomy device. By successfully cutting the entrapped and untangled guidewire within the CTO with the use of a rotational atherectomy device, we could effectively remove the Gaia guidewire from the right coronary artery.

BACKGROUND: Because of the challenges in treating calcified coronary artery disease (CAD), lesion preparation has become increasingly important prior to percutaneous coronary intervention (PCI). Despite growing data for both rotational atherectomy (RA) and orbital atherectomy (OA), there have been no multicenter studies comparing the safety and efficacy of both. We sought to examine the clinical outcomes of patients with calcified CAD who underwent atherectomy. METHODS: A total of 39 870 patients from five tertiary care hospitals who had PCI from January 2011 to January 2017 were identified...

OBJECTIVES: This study evaluated angiographic success and in-hospital outcomes of percutaneous coronary intervention (PCI) with rotational atherectomy (RA) in patients with low left ventricular ejection fraction (LVEF). DESIGN: Between January 2010 and March 2014, 272 consecutive patients with heavily calcified lesions underwent elective PCI with RA. Of these, 33 patients had LVEF ≤35% (low LVEF group), whereas 237 patients had LVEF >35% (preserved LVEF group)...

OBJECTIVES: To evaluate the outcomes of rotational atherectomy for heavily-calcified side branches of coronary bifurcation lesions. BACKGROUND: Side-branch (SB) preservation is clinically important but technically challenging in heavily-calcified non-left main true bifurcation lesions. SB rotational atherectomy (SB RA) is sometimes mandatory but the clinical outcomes are not well studied. METHODS: We retrospectively studied the outcomes of patients who underwent RA at our institute for heavily calcified, balloon-uncrossable or-undilatable SB lesions over an approximately 5-year period (January 2011 to September 2016)...

We sought to clarify intravascular ultrasound (IVUS) features of rotational atherectomy (RA) of calcified lesions. IVUS was performed post-RA and post-stent in 38 lesions and analyzed every 1 mm. Pre-intervention IVUS was performed when the IVUS catheter crossed the lesion (n = 11). Calcium Index was average calcium angle multiplied by calcium length. We compared lowest (n = 13), middle (n = 13), and highest (n = 12) Calcium Index tertiles. Reverberations (multiple reflections from calcium) with a concave-shaped lumen in the post-RA IVUS were considered to represent RA-related calcium modification...

BACKGROUND: This study was designed to confirm in a large population of unselected patients the promising results of Ultimaster® biodegradable polymer sirolimus-eluting stent (BP-SES) already shown in previous trial. METHODS: ULISSE is an observational, multicenter, national registry evaluating all patients undergoing PCI with the Ultimaster® BP-SES. Incidence of 1-year TLF (cardiac death or target vessel MI or clinically indicated TLR) was the primary endpoint...

Percutaneous coronary intervention (PCI) involving the anomalous coronary artery is challenging with respect to difficulty in achieving stable catheterization. Rotational atherectomy (RA) can facilitate severely calcified lesions to improve stent delivery and stent expansion; however, its utility in tortuous and angulated coronary arteries is limited with difficulty in delivery of the RA burr. The mother-and-child technique is effective for complex PCIs with increased backup force for device delivery in such complicated cases...

BACKGROUND: Experiences of rotational atherectomy (RA) followed by drug-coated balloon (DCB) dilation alone (RA/DCB) for de novo coronary artery lesion have been limited. CASE SERIES: Case 1 (65 year-old male) with silent myocardial ischemia and hemodialysis had old anterior myocardial infarction and intact LM/LCx, and underwent RA/DCB against a diffuse calcified lesion in the proximal LAD and a tandem lesion in the proximal RCA. Case 2 (88 year-old female) with post-infarction unstable angina had severe thrombocytopenia and anemia due to myelodysplastic syndrome (platelet 6000/μL, hemoglobin 8...

Several chronic total occlusions (CTOs) may be undilatable despite successful wire passage; several techniques can be used for lesion preparation, such as high-pressure balloon inflations, rotational atherectomy laser, cutting balloon, and scoring balloons. Presence of moderate to severe calcification and lesion length over 40 mm in association with comorbidities, such as diabetes mellitus and reduced ejection fraction, may contribute to making a CTO lesion undilatable. Still, appropriate therapy selection for a patient with CTO should be individualized and procedure safety attended to...

INTRODUCTION: Elective insertion of a percutaneous circulatory assist device (PCAD) in high-risk patients is considered a reasonable adjunct to percutaneous coronary intervention (PCI). There is limited data examining the safety and efficacy of rotational atherectomy (RA) without hemodynamic support in patients with reduced left ventricular ejection fraction (LVEF). METHODS: We retrospectively identified 131 consecutive patients undergoing RA without elective PCAD over a three-year period...

The feasibility, safety, and high technical success of robotically assisted percutaneous coronary intervention (PCI) for the treatment of both simple and complex coronary disease has been demonstrated. As the current generation robotic platform is limited to a rapid exchange system, orbital or rotational atherectomy cannot be performed robotically. However, excimer laser coronary atherectomy is performed with a rapid exchange catheter but its feasibility during robotically assisted PCI is unknown. We report the successful use of laser atherectomy during two complex robotically assisted PCI procedures using the CorPath GRX robotic system...
