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...

BACKGROUND: Although radial access for drug-eluting stent (DES) combined with rotational atherectomy (RA) in patients with calcified coronary lesions may be associated with a lower risk of major bleeding complications and obtain favorable clinical results compared with femoral access, the long-term outcome data of this approach were limited in contemporary DES era. METHODS & RESULTS: This retrospective study sought to compare in-hospital and long-term outcomes for patients undergoing RA via the transradial (TR) and transfemoral (TF) route in 126 consecutive patients (59 radial, 67 femoral) from 2009 to 2014...

Coronary perforation (CP) is a life-threatening complication that can occur during percutaneous coronary intervention (PCI). Little is known, however, about the incidence and clinical outcome of CP. We sought to investigate the occurrence of CP and its determinants and risk profile in a large-scale, prospective registry. From 2005 to 2008, unselected patients (n = 42,068) from 175 centers in 33 countries who underwent a PCI procedure were prospectively enrolled in the PCI registry of the Euro Heart Survey program...

BACKGROUND: Percutaneous coronary intervention (PCI) with drug-eluting stents is the standard of care for treatment of native coronary artery stenoses, but optimum treatment strategies for bare metal stent and drug-eluting stent in-stent restenosis (ISR) have not been established. We aimed to compare and rank percutaneous treatment strategies for ISR. METHODS: We did a network meta-analysis to synthesise both direct and indirect evidence from relevant trials. We searched PubMed, the Cochrane Library Central Register of Controlled Trials, and Embase for randomised controlled trials published up to Oct 31, 2014, of different PCI strategies for treatment of any type of coronary ISR...

Despite major advances in its diagnosis and management, coronary artery disease remains the major cause of death accounting for 45.3 percent of all deaths in the United States. One of the major milestones in the treatment of coronary artery disease has been the introduction of non-surgical revascularization in the form of percutaneous transluminal coronary angioplasty by Andreas Gmentzig in 1977. In the early years, PTCA could only be performed in proximal, discrete, non-calcified lesions. Over the last decade, major advances in the catheter, balloon and guide wire technology as well as increased operator experience extended the benefits of PTCA to patients with more complex lesions and multivessel coronary artery disease...

BACKGROUND: The outcome of percutaneous coronary intervention (PCI) has been reported to be poor in hemodialysis (HD) patients even in the drug-eluting stent era. We have reported relatively poor outcomes after sirolimus-eluting stent implantation in the OUCH study. METHODS: The OUCH-TL study is a prospective, non-randomized, single-arm registry designed to assess the results of paclitaxel-eluting stent (PES) in HD patients with follow-up quantitative coronary angiography analysis...

Rotational atherectomy is an indispensable modality for percutaneous coronary intervention of severely calcified lesions. An entrapped rotablator burr is a rare but life-threatening complication because retrieval is difficult. Although emergent surgical removal is a reliable option for this complication, it is invasive. There are various methods to retrieve an entrapped burr by bailout endovascular approaches. We present two cases of successful rescue of stuck rotablator burr entrapment using a Kiwami straight catheter (4 Fr, Heartrail II, Terumo, Tokyo, Japan)...

A 78-year-old man on dialysis with a history of femoro-popliteal bypass grafting of his right superficial femoral artery was presented with a recurrence of intermittent claudication. Angiography revealed new heavily calcified stenosis located distal to the anastomosis of the graft. A guide wire was crossed the lesion, however, a balloon catheter could not pass. Rotational atherectomy with Rotablator enabled the balloon to cross the lesion with full dilatation. Due to residual stenosis and dissection, a stent was implanted...
