JACC: CARDIOVASCULAR INTERVENTIONS. A Practical Approach to Mechanical Circulatory Support in Patients Undergoing Percutaneous Coronary Intervention. An Interventional Perspective

Tamara M. Atkinson, MDa; E. Magnus Ohman, MDb; William W. O’Neill, MDc; Tanveer Rab, MDd; Joaquin E. Cigarroa, MDa

Percutaneous mechanical circulatory support has been used to stabilize patients in cardiogenic shock and provide hemodynamic support during high-risk percutaneous coronary interventions for several decades. The goal of this paper is to provide a practical approach to percutaneous mechanical circulatory support in patients undergoing percutaneous coronary intervention with cardiogenic shock and/or high risk features to aid in decision making for interventional cardiologists.

Objectives: The aim of this study was to test the hypothesis that real-time magnetic resonance imaging (MRI) would enable closed-chest percutaneous cavopulmonary anastomosis and shunt by facilitating needle guidance along a curvilinear trajectory, around critical structures, and between a superior vena cava “donor” vessel and a pulmonary artery “target.”

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Outcomes With Intravascular Ultrasound-Guided Stent Implantation. A Meta-Analysis of Randomized Trials in the Era of Drug-Eluting Stents

Islam Y. Elgendy, MD*, Ahmed N. Mahmoud, MD*, Akram Y. Elgendy, MD and Anthony A. Bavry, MD, MPH

Background: In the era of drug-eluting stents, it is unknown if intravascular ultrasound (IVUS) guidance for percutaneous coronary intervention should be routinely endorsed. This study aimed to determine if IVUS-guided stent implantation is associated with improved outcomes.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Cardiac Catheterization. Effectiveness of Arterial Closure Devices for Preventing Complications With Percutaneous Coronary Intervention

Neil J. Wimmer, MD, MSc, Eric A. Secemsky, MD, MSc, Laura Mauri, MD, MSc, Matthew T. Roe, MD, MHS, Paramita Saha-Chaudhuri, PhD, David Dai, PhD, James M. McCabe, MD, Frederic S. Resnic, MD, MSc, Hitinder S. Gurm, MBBS and Robert W. Yeh, MD, MSc

Background: Bleeding is associated with poor outcomes after percutaneous coronary intervention (PCI). Although arterial closure devices (ACDs) are widely used in clinical practice, whether they are effective in reducing bleeding complications during transfemoral PCI is uncertain. The objective of this study was to evaluate the effectiveness of ACDs for the prevention of vascular access site complications in patients undergoing transfemoral PCI using an instrumental variable approach.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Congenital Heart Disease. Intentional Fracture of Maximally Dilated Balloon-Expandable Pulmonary Artery Stents Using Ultra–High-Pressure Balloon Angioplasty. A Preliminary Analysis

Brian H. Morray, MD, Doff B. McElhinney, MD, Audrey C. Marshall, MD and Diego Porras, MD

Background: Treatment with endovascular stents has become increasingly common for the management of vascular stenosis in congenital heart disease. The use of stents in smaller patients has been tempered by concerns about the potential for stent expansion to accommodate somatic growth. One solution to limited stent diameter is the intentional fracture of maximally dilated stents, which can be accomplished using ultra–high-pressure (UHP) balloons.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Congenital Heart Disease. Percutaneous Common Carotid Artery Access for Pediatric Interventional Cardiac Catheterization

Henri Justino, MD and Christopher J. Petit, MD

Background: Surgical cutdown for access to the common carotid artery provides a more direct route for certain pediatric cardiac interventions and avoids femoral artery injury in small infants. The safety of percutaneous carotid access (PCA) in children is unknown.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Artery Disease. Long-Term Clinical Outcomes After Bioresorbable Vascular Scaffold Implantation for the Treatment of Coronary In-Stent Restenosis

Elisabetta Moscarella, MD*, Alfonso Ielasi, MD*, Francesco Granata, MD, Sebastian Coscarelli, MD, Eugenio Stabile, MD, PhD, Azeem Latib, MD, Bernardo Cortese, MD, Maurizio Tespili, MD, Akihito Tanaka, MD, Claudia Capozzolo, MD, Luigi Caliendo, MD, PhD, Antonio Colombo, MD and Attilio Varricchio, MD, PhD

Background: Treatment of in-stent restenosis (ISR) is still challenging. In this setting, the use of bioresorbable vascular scaffold (BVS) seems attractive because it allows drug delivery combined with transient vessel scaffolding. We aimed to investigate the long-term results after BVS use in ISR lesions.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Interventions. Outcomes Following Primary Percutaneous Coronary Intervention in Patients With Previous Coronary Artery Bypass Surgery

Javaid Iqbal, MBBS, PhD*, Chun Shing Kwok, MBBS, MSc, BSc*, Evangelos Kontopantelis, PhD, Mark A. de Belder, MD, Peter F. Ludman, MD, Marilena Giannoudi, Mark Gunning, MD, Azfar Zaman, MD† and Mamas A. Mamas, BM BCh, DPhil†; on behalf of the British Cardiovascular Intervention Society (BCIS) and the National Institute for Cardiovascular Outcomes Research (NICOR)

Background: There are limited data on outcomes of patients with previous coronary artery bypass grafting (CABG) presenting with ST-segment–elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PPCI). We report outcomes in patients with STEMI undergoing PPCI with or without previous CABG surgery in a large real-world, all-comer population.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Interventions. Novel Sirolimus–Coated Balloon Catheter. In Vivo Evaluation in a Porcine Coronary Model

Yvonne Patricia Clever, MD, Daniel Peters, PhD, Jorge Calisse, PhD, Stephanie Bettink, MSc, Madeleine-Caroline Berg, PhD, Christian Sperling, MD, Michael Stoever, PhD, Bodo Cremers, MD, Bettina Kelsch, PhD, Michael Böhm, MD, Ulrich Speck, PhD and Bruno Scheller, MD

Background: Limus-eluting stents are dominating coronary interventions, although paclitaxel is the only drug on balloon catheters with proven inhibition of restenosis. Neointimal inhibition by limus-coated balloons has been shown in few animal studies, but data from randomized clinical trials are not available. The aim of the present preclinical studies was to achieve high and persistent sirolimus levels in the vessel wall after administration by a coated balloon.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Physiologic Assessment and Imaging. Optical Coherence Tomography–Guided Percutaneous Coronary Intervention in ST-Segment–Elevation Myocardial Infarction. A Prospective Propensity–Matched Cohort of the Thrombectomy Versus Percutaneous Coronary Intervention Alone Trial

Tej N. Sheth, MD, Olli A. Kajander, MD, PhD, Shahar Lavi, MD, Ravinay Bhindi, MBBS, PhD, Warren J. Cantor, MD, MSc, Asim N. Cheema, MD, PhD, Goran Stankovic, MD, PhD, Kari Niemelä, MD, PhD, Madhu K. Natarajan, MD, MSc, Olga Shestakovska, MSc, Rachel Tittarelli, BSc, MRT, Brandi Meeks, MEng and Sanjit S. Jolly, MD, MSc

Background: Patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment–elevation myocardial infarction are at increased risk for adverse events. It is unclear if image guidance by optical coherence tomography (OCT) can improve outcomes in these patients. We compared OCT-guided versus angiography-guided primary PCI for ST-segment–elevation myocardial infarction among patients in the Thrombectomy Versus PCI Alone (TOTAL) trial.
