This study examines the acute procedural success of novel devices that facilitate either true lumen or subintimal navigation across popliteal and below-the-knee (BTK) CTOs. Viance and CrossBoss catheters were associated with an overall 70% procedural success with predominantly true lumen crossing in a BTK-CTO cohort; CTO length remains an important determinant of device success. ...

Angiographic Profile and Endovascular Interventions in Takayasu’s Arteritis

Ajit Pal Singh, MD, DM1;  Srinivas Budanur Chikkaswamy, MD, DM1;  Soumya Patra, MD1;  Madhav Hegde, MD2;
K.S. Ravindranath, MD, DM1;  Mahimarangaiha Jayaranganath, MD, DM3;  Cholenahally Nanjappa Manjunath, MD, DM1

Takayasu’s arteritis (TA) is a rare inflammatory, granulomatous vasculitis primarily involving the aorta and its major branches. This study analyzes and describes the clinical features, angiographic profile, and endovascular interventions in 62 TA patients and concludes that percutaneous balloon angioplasty with stent implantation is feasible in this cohort.

We analyzed data from the ongoing multicenter XLPAD registry to report on the use of non-stent (atherectomy ± balloon angioplasty) and stent-based treatment of superficial femoral ar-tery (SFA), popliteal, and below-the-knee (BTK) vessels in contemporary clinical practice. Operators use stents to primarily treat complex SFA lesions with overall similar outcomes, except for fewer amputations compared to a non-stent strategy....

Automated Carbon Dioxide Digital Angiography for Lower-Limb Arterial Disease Evaluation: Safety Assessment and Comparison With Standard Iodinated Contrast Media Angiography

Filippo Scalise, MD1;  Eugenio Novelli, PhD2;  Carla Auguadro, MD1;  Valentina Casali, MD1;
Mariella Manfredi, MD1;  Romano Zannoli, PhD, EngD3

Carbon dioxide digital subtraction angiography is a valuable and safe alternative to traditional iodinated contrast media for evaluating CLI patients. This 40-patient study supports that this modality should be considered as the standard choice for CLI patients undergoing angiographic evaluation who are known to have renal insufficiency or contrast allergy....

The Utility of Extension Catheters in Transradial Percutaneous Coronary Intervention

Tak W. Kwan, MD1;  Ravi Diwan, MD1;  Justin A. Ratcliffe, MD1;  David James, MD1;  Rahul Patri, MD1;  Yili Huang, DO1;   Michael Liou, MD1;  Aravinda Nanjundappa, MD2;  Ramesh Daggubati, MD3;  Samir Pancholy, MD4;  Tejas Patel, MD5

An evaluation of the use of extension catheters in transradial intervention of complex coronary lesions. The use of an extension catheter may assist in improving successful intervention and decrease the frequency of crossover to a femoral approach....

The Power of the Story in an Era of Big Data and Huge Databases

Dr Blankenship opines on the enduring value of the case report in scientific literature.


Transradial Versus Transfemoral Intervention for the Treatment of Left Main Coronary Bifurcations: Results From the COBIS (COronary BIfurcation Stenting) II Registry

Seungmin Chung, MD1;  Jeong Hoon Yang, MD1;  Seung-Hyuk Choi, MD1;  Young Bin Song, MD1;
Joo-Yong Hahn, MD1;  Jin-Ho Choi, MD1;  Sang Hoon Lee, MD1;  Yangsoo Jang, MD2;  Jung Han Yoon, MD3;
Seung-Jea Tahk, MD4;  Ki-Bae Seung, MD5;  Hyeon-Cheol Gwon, MD1

We compared clinical outcomes of transradial (TR) and transfemoral (TF) percutaneous coronary interventions (PCI) in patients with left main coronary artery (LMCA) bifurcation lesions. TR-PCI is a safe and effective vascular approach even in patients with LMCA bifurcation lesions undergoing PCI with DES implantation....

New-Onset Atrial Fibrillation After Surgical Aortic Valve Replacement and Transcatheter Aortic Valve Implantation: A Concise Review

Troels Højsgaard Jørgensen, MS1;  Julie Bjerre Thygesen, MD1;  Hans Gustav Hørsted Thyregod, MD2;
Jesper Hastrup Svendsen, MD, DMSc1,3;  Lars Søndergaard, MD, DMSc1

After surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI), the incidence of new-onset atrial fibrillation (NOAF) is 31%-64% and 4%-32%, respectively. We examine the predisposing factors, optimal postprocedural monitoring, and prophylactic antiarrhythmic and antithrombotic therapy for NOAF....

A Short Review of Catheter-Based Superficial Venous Disease Management: New Directions, New Paradigms

Julian J. Javier, MD

This review examines the current situation of catheter-based vein interventions with an emphasis on tumescentless versus thermal-injury techniques to treat superficial venous insufficiency....

Lesion Flow Coefficient: A Combined Anatomical and Functional Parameter for Detection of Coronary Artery Disease — A Clinical Study

Srikara V. Peelukhana, MS1,3;  Mohamed Effat, MD2,3;  Kranthi K. Kolli, MS1,3;  Imran Arif, MD2,3;
Tarek Helmy, MD2,3;  Massoud Leesar, MD4;  Hanan Kerr, MD3;  Lloyd H. Back, PhD5;  Rupak Banerjee, PhD, PE1,3

Invasive diagnosis of coronary artery disease utilizes either anatomical or functional measurements. In this study, we tested a futuristic parameter, lesion flow coefficient, that combines both the anatomical (percent aortic stenosis) and functional measurements (pressure and flow) for application in a clinical setting. ...
