Maggioni, MD16;  Leonardo Bolognese, MD17; for the WARfarin and Coronary STENTing  (WAR-STENT) Study Group 

This study obtains further, and more focused, information on the efficacy and safety of three antithrombotic regimens prescribed to patients on oral anticoagulation undergoing percutaneous coronary intervention with stent implantation by analyzing the database of the WAR-STENT registry....

Clinical and Angiographic Outcomes After Drug-Eluting Stent Implantation With Triple-Kissing-Balloon Technique for Left Main Trifurcation Lesion: Comparison of Single-Stent and Multi-Stent Procedures

Shunsuke Kubo, MD;  Kazushige Kadota, MD, PhD;  Mahmoud Sabbah, MD;  Suguru Otsuru, MD; Daiji Hasegawa, MD;  Seiji Habara, MD;  Takeshi Tada, MD, PhD;  Hiroyuki Tanaka, MD;  Yasushi Fuku, MD; Harumi Katoh, MD, PhD;  Tsuyoshi Goto, MD;  Kazuaki Mitsudo, MD

This study evaluated clinical and angiographic outcomes after drug-eluting stent (DES) implantation with triple-kissing-balloon technique (triple-KBT) for left main (LM) trifurcation lesions and compared them between single-stent and multi-stent procedures....

Effect of Caffeine on Intravenous Adenosine-Induced Hyperemia in Fractional Flow Reserve Measurement

Hidenari Matsumoto, MD, PhD1,*;  Kenji Nakatsuma, MD1,*;  Toshihiko Shimada, MD2;  Shunpei Ushimaru, MD1; Mikiko Mikuri, MD1;  Taketoshi Yamazaki, MD, PhD1;  Tetsuya Matsuda, MD, PhD3

The interaction between caffeine and adenosine is still a matter of debate. Our aims were to both examine whether caffeine attenuated intravenous adenosine-induced hyperemia in the measurement of fractional flow reserve (FFR) and if an increased dose of adenosine overcame the caffeine antagonism. ...

Correlation Between Markers of Reperfusion and Mortality in ST-Elevation Myocardial Infarction: A Systematic Review

Sudhakar Sattur, MD;  Bilal Sarwar, MD;  Terrence J. Sacchi, MD;  Sorin J. Brener, MD

Early reperfusion improves STEMI outcomes. Reperfusion can be assessed using angiographic (Thrombolysis in Myocardial Infarction flow grade or myocardial blush grade) or electrocardiographic markers (ST-segment recovery). Our aim was to correlate early and late mortality with markers of reperfusion in ST-elevation myocardial infarction....

New Modified Balloon-Assisted Technique to Provide Appropriate Deployment in the Closure of Large Secundum Atrial Septal Defect Using Amplatzer Septal Occluder in Children

Nazmi Narin, MD1;  Ali Baykan, MD1;  Mustafa Argun, MD¹;  Abdullah Ozyurt, MD¹;  Ozge Pamukcu, MD¹;  Adnan Bayram, MD2;  Kazim Uzum, MD¹ 

Transcatheter closure of secundum atrial septal defect (ASD) is accepted as a safe alternative method to surgery, but can be challenging with large ASDs.This study compared large ASD closure using the modified BAT versus a group who underwent closure with the conventional method....

Mitral Regurgitation During Transcatheter Aortic Valve Implantation: The Same Complication With a Different Mechanism

José López-Aguilera, MD;  Dolores Mesa-Rubio, MD, PhD;  Martin Ruiz-Ortiz, MD, PhD;  Mónica Delgado-Ortega, MD, PhD;  Elena Villanueva-Fernández, MD;  Elias Romo-Peña, MD, PhD; Manuel Pan Álvarez-Ossorio, MD, PhD;  José Suárez de Lezo, MD, PhD 

Mitral regurgitation (MR) is a complication that may occur during transcatheter aortic valve implantation (TAVI) and may require different treatments depending on the mechanism. We assessed the usefulness of transesophageal echocardiogram in the detection of the mechanism of MR....

TAVI in the Case of Preexisting Mitral Prosthesis: Tips & Tricks and Literature Review

Manolis Vavuranakis, MD, PhD;  Dimitrios A. Vrachatis, MD, MSc;  Maria G. Kariori, MD;  Carmen Moldovan, MD;  Konstantinos Kalogeras, MD;  Maria Lavda, MD;  Konstantinos Aznaouridis, MD;  Christodoulos Stefanadis, MD, PhD

Limited data exist on transcatheter aortic valve implantation in the setting of a preexisting mitral prosthesis. We report two cases of transfemoral TAVI with a self-expanding bioprosthesis in patients who had previously undergone mitral valve replacement....

Variability in Freedom From Loss of Primary Patency Results in Trials Assessing Stent Implantation in the Superficial Femoral Artery

Moshe Vardi, MD1;  Lanyu Lei, MSc1;  Siyi Shangguan, MD, MPH2;  Gheorghe Doros, PhD1,3

We analyzed the implications of applying different methods in assessing freedom from loss of primary latency in studies assessing stenting for diseased superficial femoral artery. The development of a unified approach is advocated.  ...

Novel OCT Flushing Technique for Complex Scenarios: Imaging During Iatrogenic Transient AV Block Induced by Intracoronary Adenosine

Miodrag J. Sreckovic, MD 1;  Nikola B. Jagic, MD, PhD1,2;  Aleksandar N. Neskovic, MD, PhD3

We report the application of a novel optical coherence tomography (OCT) flushing technique where OCT run was performed during transient complete atrioventricular block induced by intracoronary bolus of adenosine....

Duplex Ultrasound for Chronic Venous Insufficiency

Joseph A. Zygmunt, Jr, RVT, RPhS

We present the duplex ultrasound protocol for chronic venous insufficiency, as well as other insightful information regarding superficial reflux, anatomy, and concepts.  ...
