The crossover balloon occlusion technique (CBOT) facilitates primary access hemostasis in patients undergoing transfemoral transcatheter aortic valve replacement. It is usually performed through the contralateral femoral artery. The aim of this multicenter study was to evaluate the safety and feasibility of transradial CBOT using the new Oceanus balloon dilatation catheter (iVascular) in 104 patients undergoing transcatheter aortic valve replacement. Data regarding transradial CBOT, balloon performance, vascular complications, and 30-day clinical events were recorded.

Peripheral Vascular Disease

Jetstream Atherectomy in Treating Femoropopliteal In-Stent Restenosis: Meta-Analysis of the JETSTREAM-ISR and JET-ISR Trials

Nicolas W. Shammas, MD, MS; Susan Jones-Miller, MS; Gail A. Shammas, BS, RN; W. John Shammas, BS, MBA

We present the results of a patient-level meta-analysis of the two currently completed and core-lab adjudicated prospective trials of the Jetstream atherectomy system (Boston Scientific) in femoropopliteal in-stent restenosis (FP-ISR) and compare the findings to a published, prespecified 6-month performance goal of target-lesion revascularization with angioplasty alone. In this meta-analysis of 92 lesions treated in 89 patients, Jetstream atherectomy in treating FP-ISR had a high freedom from target-lesion revascularization despite no adjunctive drug-coated balloon use.

Transcatheter Aortic Valve Replacement 

Sex-Related Differences in Early- and Long-Term Mortality After Transcatheter and Surgical Aortic Valve Replacement: A Systematic Review and Meta-Analysis

Symptomatic aortic stenosis is a common valvular heart disease that leads to a high rate of death if left untreated.Transcatheter aortic valve replacement is the standard of care to treat patients with aortic stenosis who are at high or prohibitive risk for surgical aortic valve replacement (SAVR). Observational data suggest that early- and long-term outcomes of transcatheter and surgical aortic valve replacement differ significantly between men and women, but have demonstrated conflicting results. This meta-analysis of 35 studies included 40,861 men and 40,067 women, and sought to examine early- and long-term mortality with transcatheter and surgical aortic valve replacement in women versus men.

Transcatheter Aortic Valve Replacement 

Patient Risk Assessment for Transcatheter Aortic Valve Replacement at Veterans Health Administration Hospitals

Our objective was to compare patient-level risk assessment at eight Veterans Affairs hospitals in patients undergoing transcatheter aortic valve replacement with patients included in the Society for Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy (STS/ACC TVT) registry from 2012-2015. Univariable and multivariable Cox proportional hazards models were used to examine 30-day and 1-year all-cause mortality, 30-day and 1-year transient ischemic attack/stroke rates, and permanent pacemaker implantation rates.

Risk Factors & Prevention

Long-Term Outcomes and Weight Loss After Bariatric Embolization of the Left Gastric Artery

Charles Pirlet, MD; Zoltan Ruzsa, MD, PhD; Balazs Nemes, MD; Paul Poirier, MD, PhD; Olivier F. Bertrand, MD, PhD

Bariatric embolization of the left gastric artery is a promising technique to induce weight loss in obese patients. We aimed to assess long-term effects by recruiting patients with severe obesity who were scheduled to undergo left gastric artery embolization via transradial access. We report clinical outcomes and weight loss in 7 men who underwent the procedure and provide outcomes up to 2 years.

Long-term outcomes of patients with prior coronary artery bypass graft surgery undergoing chronic total occlusion percutaneous coronary intervention have received limited study. We compared the clinical and angiographic characteristics and procedural and follow-up outcomes of 1572 patients (498 patients with and 1074 patients without prior coronary artery bypass graft surgery) from the multicenter international PROGRESS-CTO registry.

Alcohol Septal Ablation

Hypertrophic Obstructive Cardiomyopathy Requiring Ablation via Septals From Both Left and Right Coronary Arteries — A Case Report and Review of Literature

Mohammed Alomar, MD; Peyman Naji, MD; Saurabh Kapoor, MD; Gautam Visvesvaran, MD; Marc Cohen, MD

Hypertrophic obstructive cardiomyopathy (HOCM) is a genetic disorder characterized by left ventricular hypertrophy that is unexplained by secondary causes of hypertrophy, and a nondilated left ventricle with preserved or increased ejection fraction. Acohol septal ablation has traditionally been performed using septal perforators from the left coronary system. We describe a 60-year-old woman in whom septal perforators from the left and right coronary arteries were utilized and review current literature on the management of HOCM.

Chronic Total Occlusion

Guide-Extension Facilitated Antegrade Dissection Re-entry: A Case Series

Thomas E. Kaier, MD, MBA, PhD; Andreas Kalogeropoulos, MD, PhD; Antonis N. Pavlidis, MD, PhD

Antegrade dissection and re-entry (ADR) is an established and safe technique for chronic total occlusion percutaneous coronary intervention, with high success rates in experienced centers. Chronic total occlusion techniques frequently require greater-than-usual guide-catheter support and rapid-exchange technologies; either can be achieved with separate guide extension and a trapping balloon. In this case series of guide-extension facilitated ADR, we highlight the technical advantages gleaned from the use of combined devices such as the TrapLiner guide-extension catheter (Teleflex).

Chronic Total Occlusion

Q-Waves Associated With Postinfarct Chronic Total Occlusion Arteries Predict Non-Viable Myocardium Even in the Presence of Collaterals

Muhammad M. Shaikh, MD; Muhammed A. Sadiq, MD; Sunil K. Nadar, MD

The presence of grade 3 collaterals is known to be associated with viability in the presence of a chronic total occlusion. However, it is not clear whether this holds true in patients who had ST-segment elevation myocardial infarction. Our study examined the viability of myocardium in patients with chronic total occlusions in both infarct-related and non-infarct related occluded vessels with grade 3 collaterals.

Left Atrial Appendage Closure  

Adverse Events After Left Atrial Appendage Closure: Lessons Learned From the Manufacturer and User Facility Device Experience (MAUDE) Database

Left atrial appendage (LAA) closure devices are alternative treatments recently approved for patients with atrial fibrillation. Due to the novelty of these devices, limited postapproval surveillance data on LAA closure devices have been published. Thus, we analyzed the United States FDA Manufacturer and User Facility Device Experience database to report these findings. The primary endpoint was final event outcome, and secondary endpoints included management strategies of reported events.
