OBJECTIVE: This first-in-human study evaluated the safety and technical feasibility of the Tempo temporary cardiac pacing lead (BioTrace Medical), which includes a novel fixation mechanism and soft tip. BACKGROUND: Complications of temporary pacing leads include dislodgment, arrhythmias, and ventricular perforation. Temporary pacing applications have increased with transcatheter aortic valve replacement (TAVR) growth, for rapid pacing during balloon valvuloplasty (BAV) and valve deployment, and for periprocedural bradyarrhythmia support...

BACKGROUND: Coronary atherectomy, orbital or rotational, is frequently used for plaque modification in patients with heavily calcified lesions. Atherectomy can be associated with clinically significant bradyarrhythmias or transient atrioventricular block requiring temporary pacemaker insertion, mainly in lesions involving the right coronary artery or a dominant left circumflex artery. Bradyarrhythmias may be mediated by endogenous release of adenosine from red blood cell breakdown. Aminophylline, an adenosine antagonist, can prevent adenosine-mediated bradyarrhythmias...

OBJECTIVES: Right heart catheterization (RHC) provides cardiovascular hemodynamic information in a variety of clinical settings. RHC performed in the setting of coagulopathy may have the potential to increase bleeding complications; however, data currently are limited. This study was undertaken to determine bleeding complications during RHC with an elevated international normalized ratio (INR) value. METHODS: A total of 312 patients who underwent RHC were retrospectively studied...

OBJECTIVES: The goal of this study is to evaluate the safety and efficacy of the second-generation robotic-assisted system CorPath GRX (Corindus) for percutaneous coronary intervention (PCI). BACKGROUND: The first-generation CorPath 200 robotic-assisted system for PCI is effective, but is limited by the lack of an active robotic guide-catheter control. The CorPath GRX device enables robotic guide-catheter manipulation, in addition to guidewire and balloon/stent delivery...

BACKGROUND: Periprocedural bleeding is associated with increased risk of early mortality during percutaneous coronary intervention (PCI), especially in patients on dialysis. A transradial approach (TRA) should be considered for these patients; however, PCI operators avoid this approach because of the risk of radial artery occlusion (RAO). The aim of this study is to construct a TRA system and clarify its safety in patients on dialysis. METHODS: Eighty-eight consecutive patients on dialysis who underwent cardiac catheterization were prospectively included in this study and divided according to the access site into either the TRA group or the transfemoral approach (TFA) group...

OBJECTIVES: The intraaortic balloon pump (IABP) is currently an essential tool to improve hemodynamics in patients with advanced heart failure (HF). This study investigated predictors for hemodynamic improvement or stabilization with IABP therapy in patients with advanced HF. METHODS: Patients with advanced HF and hemodynamic deterioration treated with IABP were enrolled in this retrospective study. Invasive hemodynamics were measured before IABP implantation and 2 weeks after IABP initiation...

OBJECTIVES: We compared the angiographic outcomes of patients treated with orbital atherectomy for profunda femoris artery (PFA) and superficial femoral artery (SFA) disease from the CONFIRM I-III registries. BACKGROUND: Endovascular revascularization of the PFA is considered a high-risk procedure given that it is an important collateral vessel when the SFA becomes occluded. Data on outcomes of endovascular revascularization of calcified PFA disease are limited...

OBJECTIVES: The outcomes of catheter ablation in focal atrial tachycardia (AT) using remote magnetic navigation (RMN) are still controversial. The objectives of this study were to assess the acute and long-term outcomes of catheter ablation in focal AT using RMN. BACKGROUND: A total of 53 patients with focal AT who underwent catheter ablation using RMN were included. Thirty-six patients had structural heart disease, including previous atrial fibrillation ablation and heart surgery (abnormal group), and the remaining 17 patients had no structural heart disease (normal group)...

OBJECTIVES: To evaluate operator pelvic radiation exposure during percutaneous coronary procedures. BACKGROUND: During percutaneous coronary procedures, the operator's pelvic region is close to the x-ray source and is probably exposed to more radiation than the operator's thorax. However, no data are available on the pelvic radiation exposure of interventional cardiologists. METHODS: The RADIANT study (NCT01974453) is a prospective, single-center, observational study evaluating operator radiation exposure during percutaneous coronary procedures using electronic dosimeters placed at thorax level...

Non-cerebral thromboembolic complications of transcatheter aortic valve implantation are rare, but life threatening. We report a 62-year-old woman with aortic stenosis who qualified for TAVI due to obesity and developed hypotension and bradycardia as a result of thromboembolic occlusion of the LCA.

A 79-year-old woman had an atretic LIMA to LAD but without significant LAD stenosis, patent SVG to OM1, patent SVG to RCA, and severe tandem lesions in a very tortuous LCX for which she underwent PCI. Placement of a BMW coronary guidewire into the LCX resulted in the straightening of the vessel.

OBJECTIVES: We assessed the impact of intravascular ultrasound (IVUS)/optical coherence tomography (OCT) on outcomes of patients who underwent orbital atherectomy. BACKGROUND: Intravascular imaging provides enhanced lesion morphology assessment and optimization of percutaneous coronary intervention (PCI) outcomes. Severe coronary artery calcification increases the complexity of PCI and is associated with worse clinical outcomes. Orbital atherectomy modifies calcified plaque, facilitating stent delivery and optimizing stent expansion...
