Abstract Fractional flow reserve (FFR) measurement provides useful hemodynamic assessment of intermediate coronary stenoses affecting long term outcomes. While the gold standard remains intravenous adenosine, intracoronary (IC) bolus administration of…
Abstract A 78 year old woman was admitted with an acute coronary syndrome. She underwent coronary angiography via the left radial artery which was complicated by a guide catheter induced…
Abstract Background/Purpose Catheter-based renal sympathetic denervation (RDN) can reduce blood pressure (BP) and sympathetic activity in certain patients with uncontrolled hypertension. Less is known about the impact of renal anatomy…
Abstract A 76-year-old hypertensive man with previous bilateral iliac stenting was admitted in our center for acute stroke with an NIH score of 20 at 6 h from symptoms onset. The…
Abstract Objective The aim of this study was to understand the role of accessory renal arteries in resistant hypertension, and to establish their role in nonresponse to radiofrequency renal denervation…
Abstract Background Long-term patency rates for percutaneous peripheral arterial interventions are suboptimal. Optical coherence tomography (OCT) guided atherectomy may yield superior patency by optimizing plaque removal while preserving the tunica…
Abstract Background and propose In coronary bifurcation lesions (CBL), hydrophilic guidewires used for side-branch (SB) protection can be withdrawn from underneath the stent easier than other wires. However, the safety…
Abstract Background Takotsubo syndrome (TS) may be triggered by innumerable physical stress factors including epinephrine administration. The aim of this study is to report on the clinical features and outcome…
Abstract Background There is limited information on optical coherence tomography (OCT) findings after percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs). OCT allows high resolution imaging that can enhance…
Abstract Introduction The aim of this study was to investigate the efficacy and safety of intracoronary (IC) sodium nitroprusside infusion in comparison to IC adenosine for fractional flow reserve (FFR)…
