Objectives:The aims of this study were to assess the epidemiology of atrial fibrillation (AF) in patients treated with transcatheter aortic valve replacement (TAVR) and included in the large prospective SOURCE XT (SAPIEN XT Aortic Bioprosthesis Multi-Region Outcome Registry) study and to evaluate their outcomes according to the presence of pre-existing or new-onset AF (NOAF) (defined as AF occurring within 30 days after TAVR).
Objectives: This study describes the characteristics of a real-world Asian patient population treated with transcatheter aortic valve replacement (TAVR) and evaluates their clinical outcomes.
Objectives: The aims of this study were to describe the 10-year experience of a single operator dedicated to chronic total occlusion (CTO) and to establish a model for predicting technical failure.
Objectives: This study assessed whether the choice of vascular access site influenced outcomes among non–ST-segment elevation myocardial infarction (NSTEMI) patients enrolled in the ACCOAST (A Comparison of prasugrel at the time of percutaneous Coronary intervention Or as pre-treatment At the time of diagnosis in patients with non–ST-segment elevation myocardial infarction NCT01015287).
Objectives: The aim of this study was to examine the frequency, associations, and outcomes of native coronary artery versus bypass graft percutaneous coronary intervention (PCI) in patients with prior coronary artery bypass grafting (CABG) in the Veterans Affairs (VA) integrated health care system.
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.”
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.
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.
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.
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.
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.
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.
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.
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.
