Background: In patients with severe aortic stenosis, transcatheter aortic valve replacement (TAVR) improves survival when compared with nonsurgical therapy but with higher in-hospital and lifetime costs. Complications associated with TAVR may decrease with greater experience and improved devices, thereby reducing the overall cost of the procedure. Therefore, we sought to estimate the effect of periprocedural complications on in-hospital costs and length of stay of TAVR.
Aim: The aim of this study was to determine the effects of advanced chronic kidney disease (CKD) on early and late outcomes after transcatheter aortic valve implantation (TAVI), and to evaluate the predictive factors of poorer outcomes in such patients.
Aims: Delcasertib is a selective inhibitor of delta-protein kinase C (delta-PKC), which reduced infarct size during ischaemia/reperfusion in animal models and diminished myocardial necrosis and improved reperfusion in a pilot study during primary percutaneous coronary intervention (PCI) for ST elevation myocardial infarction (STEMI).
Aim: The aim of this study was to evaluate whether coronary artery disease (CAD) severity exerts a gradient of risk in patients with aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI).
Aim: Transcatheter aortic valve implantation has become an alternative to surgery in higher risk patients with symptomatic aortic stenosis. The aim of the ADVANCE study was to evaluate outcomes following implantation of a self-expanding transcatheter aortic valve system in a fully monitored, multi-centre ‘real-world’ patient population in highly experienced centres.
Aims: This study aimed to evaluate incidence and correlates for low platelet count after transcatheter aortic valve replacement (TAVR) and to determine a possible association between acquired thrombocytopenia and clinical outcomes.
Aims: We reported that patients with small aortic valve area (AVA) and low flow despite preserved left ventricular ejection fraction (LVEF), i.e. ‘paradoxical’ low flow (PLF), have worse outcomes compared with patients with normal flow (NF), although they generally have a lower mean gradient (MG). The aortic valve weight (AVW) excised at the time of valve replacement is a flow-independent marker of stenosis severity. The objective of this study was to compare the AVW of patients with PLF and MG<40 mmHg with the AVW of patients with NF and MG≥40 mmHg.
Aims: The present analysis addresses the potential clinical and physiologic significance of discordance in severity of coronary artery disease between the angiogram and fractional flow reserve (FFR) in a large and unselected patient population.
Background: The risk of mortality for patients presenting to the cardiac catheterization laboratory with stent thrombosis (ST) may differ as a function of the timing from initial stent implantation. We hypothesized that the 30-day mortality would differ for angiographically defined early ST (EST), late ST (LST), and very late ST (VLST).
Objective: To evaluate access site and other bleeding complications associated with radial versus femoral access in patients receiving oral anticoagulation (OAC) with warfarin.
Background: Multidetector computed tomography (MDCT) provides detailed assessment of valve annulus and iliofemoral vessels in transcatheter aortic valve replacement (TAVR) patients. However, data on diagnostic performance of MDCT coronary angiography (MDCT-CA) are scarce. The aim of the study is to assess diagnostic performance of MDCT for coronary artery evaluation before TAVR.
Background: Radiation exposure in the pediatric population may increase the risk of future malignancy. Children with congenital heart disease who often undergo repeated catheterizations are at risk. One possible strategy to reduce radiation is to use X-ray Magnetic Resonance Fusion (XMRF) to facilitate cardiac catheterization.
Objectives: Our objective was to determine if technical changes combined with radiation safety initiatives reduced the radiation dose delivered to patients during congenital catheterization.
Neurological complications of coarctation of aorta include spontaneous SAH, intracerebral hemorrhage, and cerebral abscess. Interrupted aortic arch (IAA) present as compressive myelopathy is not known. We describe an adult male presenting to neurology department with progressive paraparesis and was detected to have IAA with intraspinal collaterals causing compressive myelopathy. He was successfully treated with percutaneous stenting of IAA with dramatic improvement in paraparesis. © 2014 Wiley Periodicals, Inc.
A very low birth weight neonate (1.2 kg) with total anomalous pulmonary venous connection and obstructed infracardiac pulmonary venous drainage was treated by stenting of the ductus venosus via a transjugular approach. With one reintervention to dilate an in-stent stenosis, the palliative stented situation stabilized the patient for as long as three months until definitive surgical correction at a weight of 2 kg. © 2014 Wiley Periodicals, Inc.
