BACKGROUND: Rotational atherectomy (RA) is an acknowledged method of percutaneous treatment of highly calcified or fibrotic coronary lesions. However, using the rotablator system in patients presenting with acute coronary syndromes (ACS) remains controversial and is considered as a relative contraindication. The aim of our study was to assess in-hospital and 1-year outcomes in patients undergoing RA presenting with ACS, in comparison to elective RA procedures. METHODS: This single-center observational study included all consecutive patients who underwent RA and PCI in our institution from April 2008 to October 2015...

BACKGROUND: Although rotational atherectomy (RA) has been an accepted and widely used medical procedure for more than 15 years, the clinical outcomes of RA in high-risk populations remain elusive. Therefore, the purpose of this study was to investigate the safety and efficacy of RA for patients with acute or recent myocardial infarction (MI), and report the short- and long-term clinical outcomes in this population. METHODS: We enrolled patients undergoing percutaneous coronary intervention (PCI) and RA at two medical centers in Taiwan between January 2004 and December 2013...

OBJECTIVES: We investigated the safety and efficacy of PCI using drug-coated balloon (DCB) after rotational atherectomy (rotablation) in a retrospective single center study in patients with calcified de novo coronary lesions. The majority of patients had an increased risk for bleeding. BACKGROUND: DCB has been effective in the treatment of in-stent restenosis, small vessels, and bifurcations. DCB enables short one month dual antiplatelet treatment. No published data exist on the use of DCB after rotablation...

Although burr entrapment is a rare complication of rotablation, it is extremely difficult to retrieve a stuck entrapped burr without surgical intervention. There are several techniques typically employed to retrieve an entrapped burr, using bailout endovascular approaches. Herein we have presented a new retrieval method involving a Guideliner child-in-mother catheter combined with a snare, which was used to successfully rescue a stuck rotablator burr.

BACKGROUND: Inability to advance a balloon is a well-recognized cause leading to a failure in recanalization of chronic total occlusions (CTOs) despite successfully passing a guidewire. A few techniques and devices have been introduced to facilitate balloon passage, especially the use of Tornus catheter. However, complex manipulation, expensive cost, and availability limit the application of these methods. This study was to evaluate the efficiency and safety of "seesaw balloon-wire cutting" technique in comparison with Tornus catheter for balloon uncrossable CTOs...

A 75-year-old man with a severe calcified atheromatous plaque of the right coronary artery underwent percutaneous coronary intervention using a Rotablator® . During the procedure, the 1.5-mm burr became entrapped, and the driveshaft fractured. While various techniques for retrieving the burr were attempted, a new technique was created. The entrapped burr was sandwiched between an inflated balloon and the GuideLiner® , and a strong back-up force was obtained. Finally, the system was pulled back safely, and the entrapped burr was retrieved without complications...

OBJECTIVE: Percutaneous coronary intervention (PCI) for the heavily calcified coronary lesions remains a challenge, and the periprocedural complication rates of the transfemoral approach are high. This study was conducted to investigate the feasibility and long-term results of the transradial approach for rotational atherectomy (RA) prior to stent implantation via the transradial approach in patients with heavily calcified coronary artery lesions. METHODS: RA followed by stent implantation via the transradial approach was performed in 47 patients with severely calcified coronary artery lesions in this retrospectively case-control study...

We report the occurrence of catheter tip erosion during use of a Rotablator, a rare but serious complication. A heavily calcified lesion of the right coronary artery ostium required use of a Rotablator, and the need for strong push led to the choice of an Amplatz Left guiding catheter. The traction of the catheter toward the ostium and the subsequent angle generated led to friction of the burr against the catheter and the erosion of its tip. If judged essential to get strong support, the Amplatz catheter should be used with caution in this setting...

We assessed the feasibility and safety of a rota-flush solution with 10,000 U of unfractionated heparin in 1 L of normal saline in patients who underwent rotational atherectomy. BACKGROUND: Rotational atherectomy with the Rotablator (Boston Scientific) rotational atherectomy system is an effective way to modify severely calcified plaque. Potential complications include coronary spasm and slow-flow/no-flow. A pressured rota-flush solution is infused into the device to lubricate the drive shaft to minimize the risk of these complications as well as facilitate delivery of the device...

Although uncommon, critical hand ischemia (CHI) represents a cause of significant disability because of its effect on hand function. Percutaneous transluminal angioplasty (PTA) is now considered a first-line therapy for above-the-elbow artery disease while there are few data regarding the treatment of below-the-elbow (BTE) arteries. The aim of this study is to review the current literature on BTE vessel PTA and to describe the technical approach. In case of favorable anatomy (absence of inflow arteries disease, standard humeral artery bifurcation), a 4-F antegrade trans-brachial approach is usually the preferred option...

BACKGROUND: Bleeding complications remain one of the most important challenges in percutaneous coronary intervention (PCI), particularly in Asians who are known to be vulnerable to the use of antiplatelets or anticoagulants. However, the incidence and predictors of bleeding complications after PCI have not been thoroughly investigated in Japan. METHODS: We studied 13,075 consecutive patients in a Japanese multicenter PCI registry (Japan Cardiovascular Database - Keio interhospital Cardiovascular Study: JCD-KiCS) from September 2008 to March 2014...

BACKGROUND: Rotational atherectomy (rotablation) has been proposed as a potentially superior strategy for percutaneous coronary intervention (PCI) in complex and severely calcified lesions. OBJECTIVES: We hypothesized that a per-lesion coronary artery calcium score determined by multidetector computed tomography (MDCT) would be useful for predicting the requriement for rotablation during PCI. METHODS: MDCT was performed in patients with stable angina pectoris who were scheduled for first PCI...

Rotablator burr entrapment occurring during rotational atherectomy is a rare but serious complication that can lead to coronary occlusion and require emergency cardiac surgery. Although several bailout techniques for stuck burrs have been proposed, no definitive methods for removal have been established. We report here a difficult case of a stuck rotablator burr, in which various techniques failed to retrieve the burr. It was ultimately removed using the subintimal tracking and reentry (STAR) technique with a 3-g tapered tip hydrophilic wire...
