Rotatripsy: A Hybrid "Drill and Disrupt" Approach for Treating Heavily Calcified Coronary Lesions.

J Invasive Cardiol 2020 Jun;32(6):E175

1st Department of Cardiology, Hippokration Hospital, 114 Vas. Sofias Avenue, 11527 Athens, Greece.

In balloon-uncrossable calcified lesions, rotational atherectomy (RA) is the first-line modality to enable operators to advance balloons and stents over the stenosis. If the lesion is undilatable after RA, a hybrid approach with additional intracoronary lithotripsy (rotatripsy) can be an effective approach that further modifies the calcified plaque and enables stent delivery.

Evaluation of safety and efficacy of coronary intravascular lithotripsy for treatment of severely calcified coronary stenoses: Design and rationale for the Disrupt CAD III trial.

Am Heart J 2020 Apr 18;225:10-18. Epub 2020 Apr 18.

Clinical Trials Center, Cardiovascular Research Foundation, New York, NY; New York-Presbyterian Hospital/Columbia University Medical Center, New York, NY; The Zena and Michael A. Wiener Cardiovascular Institute, Icahn School of Medicine at Mount Sinai, New York, NY.

Coronary calcification limits optimal stent expansion and apposition and worsens safety and effectiveness outcomes of percutaneous coronary intervention (PCI). Current ablative technologies that modify calcium to optimize stent deployment are limited by guidewire bias and periprocedural complications related to atheroembolization, coronary dissection, and perforation. Intravascular lithotripsy (IVL) delivers pulsatile ultrasonic pressure waves through a fluid-filled balloon into the vessel wall to modify calcium and enhance vessel compliance, reduce fibroelastic recoil, and decrease the need for high-pressure balloon (barotrauma) inflations.

U.O. Cardiologia, Azienda Ospedaliero-Universitaria di Ferrara, Cona (FE) - Maria Cecilia Hospital, GVM Care & Research, Cotignola (RA).

Stent under-expansion represents a negative prognostic factor, because of the risk to develop intrastent restenosis and stent thrombosis. It is often due to excessive calcium burden at the target lesion level. The list of devices available for the treatment of stent under-expansion includes super high-pressure non-compliant (NC) balloons, excimer laser and intravascular lithotripsy. Read More

The Impact of Ureteral Access Sheath Use on the Development of Abnormal Postoperative Upper Tract Imaging after Ureteroscopy.

J Urol 2020 May 27:101097JU0000000000001147. Epub 2020 May 27.

Department of Urology, The Ohio State University Medical Center, Columbus, Ohio.

Introduction: Ureteral access sheaths (UAS) are commonly utilized during ureteroscopy (URS) to facilitate stone removal, improve visibility and maintain low intrarenal pressures. However, the use of a UAS can cause ureteral wall ischemia and ureteral tears, potentially increasing the risk of postoperative ureteral stricture and obstruction. The primary objective of this study was to study the impact that UAS use has on postoperative imaging studies. Read More

Ultrasound-Guided Minimally Invasive Percutaneous Nephrolithotomy is Effective in the Management of Pediatric Upper Ureteral and Renal Stones.

J Invest Surg 2020 May 13:1-5. Epub 2020 May 13.

Urology and Lithotripsy Center, Peking University People's Hospital, Beijing, China.

To evaluate the outcome of ultrasound (US)-guided minimally invasive percutaneous nephrolithotomy (MPCNL) in the management of upper ureteral and renal stones in pediatric patients. We collected data of 112 pediatric patients who were admitted to the xxxx between March 2006 and December 2016 and treated by US-guided MPCNL. Our cohort included upper ureter stones ( = 11), single kidney stones ( = 46), multiple kidney stones ( = 56), and staghorn kidney stones ( = 12). Read More

Efficacy of Eutectic Mixture of Local Anesthetics on Pain Control During Extracorporeal Shock Wave Lithotripsy: A Systematic Review and Meta-Analysis.

Med Sci Monit 2020 May 13;26:e921063. Epub 2020 May 13.

Department of Urology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China (mainland).

BACKGROUND The efficacy of a eutectic mixture of local anesthetics (EMLA) for pain control in extracorporeal shock wave lithotripsy is unclear. The aim of this study was to assess the effect of EMLA cream on pain control during extracorporeal shock wave lithotripsy. MATERIAL AND METHODS We searched Medline, EMBASE, and the Cochrane Central Register of Controlled Trials to identify relevant randomized controlled trials that compared the pain control efficacies of EMLA vs. Read More

Current developments in endovascular therapy of peripheral vascular disease.

J Thorac Dis 2020 Apr;12(4):1681-1694

Division of Cardiology, Rocky Mountain Regional VA Medical Center, University of Colorado, Aurora, CO, USA.

More than 200 million people worldwide have peripheral artery disease (PAD) or its most severe manifestation, critical limb ischemia (CLI). While endovascular treatment has become first line therapy in most cases, a number of challenges remain for optimal treatment of femoropopliteal (FP) or infrapopliteal (IP) disease, especially when these lesions are severely calcified, chronic total occlusions (CTOs) or in-stent restenosis (ISR). Continued evolution of technologies has significantly improved the outcomes for endovascular treatment. Read More

Production of ERCP training model using a 3D printing technique (with video).

BMC Gastroenterol 2020 May 11;20(1):145. Epub 2020 May 11.

Research Group for Endoscopic Instruments and Stents, Korean Society of Gastrointestinal Endoscopy, Seoul, Korea.

Background: ERCP training models are very different in terms of anatomical differences, ethical issues, storage problems, realistic tactile sensation, durability and portability. There is no easy way to select an optimized model for ERCP training. If the ERCP training model could be made as a soft silicone model using 3D printing technique, it would have numerous advantages over the models presented so far. Read More

Incidence and Significance of Biliary Stricture in Chronic Pancreatitis Patients Undergoing Extracorporeal Shock Wave Lithotripsy for Obstructing Pancreatic Duct Stones.

Gut Liver 2020 May 13. Epub 2020 May 13.

Digestive Disease Institute, Virginia Mason Medical Center, Seattle, WA, USA.

Background/aims: This study assessed the significance of biliary stricture in symptomatic chronic pancreatitis patients requiring extracorporeal shock wave lithotripsy (ESWL) and endoscopic retrograde cholangiopancreatography (ERCP) to remove obstructing pancreatic calculi.

Methods: A total of 97 patients underwent ESWL followed by ERCP to remove pancreatic calculi between October 2014 and October 2017 at Virginia Mason Medical Center. Significant biliary stricture (SBS) was defined as a stricture with upstream dilation on computed tomography scan or magnetic resonance cholangiopancreatography scans accompanied by cholestasis and/or cholangitis.

Peroral Cholangioscopy-guided Electrohydraulic Lithotripsy with a SpyGlass DS Versus a Conventional Digital Cholangioscope for Difficult Bile Duct Stones.

Intern Med 2020 May 8. Epub 2020 May 8.

Department of Gastroenterology, Sendai City Medical Center, Japan.

Objective Recently, a new digital peroral cholangioscopy (POCS) system, the SpyGlass DS (SpyDS), has been used for POCS-guided lithotripsy for difficult bile duct stones (DBDSs). The aim of this retrospective study was to compare the efficacy of SpyDS-guided electrohydraulic lithotripsy (EHL) for DBDS with that of a conventional digital cholangioscope. Methods and Patients Seventeen consecutive patients who had undergone POCS-guided EHL for DBDS with the SpyDS between October 2015 and January 2019 were enrolled in this study group (SpyDS group) using a prospectively maintained database.

Cardiovasc Revasc Med 2020 Apr 29. Epub 2020 Apr 29.

Section of Interventional Cardiology, MedStar Washington Hospital Center, Washington, DC, United States of America.

Background: Intravascular lithotripsy (IVL) (Shockwave Medical, Inc., Fremont, California, USA) is a novel technology used to modify heavily calcified atherosclerotic plaque in vessels to help facilitate percutaneous coronary intervention and has been shown to be effective in treating critical lesions within the lower limbs. In addition, studies are currently underway evaluating IVL's feasibility in de novo calcified stenotic coronary arteries before stenting. Read More
