Hemodynamic indices derived from measurements with the pressure wire (primarily fractional flow reserve [FFR]) have been established as a reliable tool for assessing coronary stenoses and improving clinical decision making. However, the use of the pressure wire constitutes a hurdle for the universal adoption of physiology-guided patient management. Technological advancements have enabled the large-scale application of blood flow simulation (computational fluid dynamics [CFD]) to medical imaging, thereby enabling the virtual assessment of coronary physiology...

In specific forms of congenital heart defects and pulmonary hypertension, the right ventricle (RV) is exposed to systemic levels of pressure overload. The RV is prone to failure in these patients because of its vulnerability to chronic pressure overload. As patients with a systemic RV reach adulthood, an emerging epidemic of RV failure has become evident. Medical therapies proven for LV failure are ineffective in treating RV failure. Areas covered: In this review, the pathophysiology of the failing RV under pressure overload is discussed, with specific emphasis on the pivotal roles of angiogenesis and oxidative stress...

Congenital complete heart block affects 1/15,000 live-born infants, predominantly due to atrioventricular nodal injury from maternal antibodies of mothers with systemic lupus erythermatosus or Sjogren's syndrome. The majority of these children will need a pacemaker implanted prior to becoming young adults. This article will review the various patient and technical factors that influence the type of pacemaker implanted, and the current literature on optimal pacing practices. Areas covered: A literature search was performed using PubMed, Embase and Web of Science...

For the past 20 years, intravenous recombinant tissue plasminogen activator (rt-PA) has been the only proven treatment for acute ischemic stroke. Large arteries such as the internal carotid artery, the middle cerebral artery and the basilar artery supply blood to large volumes of brain tissue. When occluded, these vessels may have low response rates to rt-PA resulting in devastating injury and death. Areas covered: In 2013, three trials evaluating the efficacy of mechanical thrombectomy in acute stroke were neutral, however, lessons learned from these trials resulted in a second generation of five trials in 2015 and a sixth in 2016 which all demonstrated significant benefit for select patients...

BACKGROUND: Familial chylomicronemia syndrome (FCS) is a rare, inherited lipid disorder characterized by high levels of plasma triglycerides and chylomicrons, which may cause life-threatening acute pancreatitis. Currently no FDA-approved treatment exists. Management is low-fat diet (<20g fat/day), which is difficult to maintain. With the restricted diet, triglycerides may remain elevated. We conducted discussions with patients and caregivers to better understand the burden of FCS from their perspectives...

Atherosclerotic cardiovascular disease (ASCVD) has become a major health burden and is expected to further increase in the future. Better predictive approaches for ASCVD and more efficacious therapies are required to further improve cardiovascular outcomes. Intravascular imaging has contributed to the elucidation of atherosclerotic mechanisms and evaluation of novel therapies. Near-infrared spectroscopy has enabled the visualization of the lipid extent of atherosclerotic plaques in vivo. Given that lipid accumulation is considered to promote the formation and progression of atherosclerosis, this technology may harbor the potential to identify subjects with high cardiovascular risks and thus adopt more optimized therapeutic approaches...

Calcific aortic valve disease (CAVD) is the most prevalent heart valve disorder. Gene variant in the LPA gene, which encodes for apolipoprotein(a), has been associated at the genome-wide level with CAVD. The process whereby Lp(a) promotes the development of CAVD is under intensive investigation and recent data have shed important insights into disease biology. In this regard, autotaxin (ATX), a lysophospholipase D, interacts with Lp(a) and promotes the mineralization of the aortic valve. Areas covered: In this paper, we are reviewing the biology of Lp(a) and the latest discoveries about the molecular processes that link this lipoprotein with the development of CAVD including the role of ATX...

Robots have been employed in cardiovascular therapy as surgical tools and for automation of hospital systems. Soft robots are a new kind of robot made of soft deformable materials, that are uniquely suited for biomedical applications because they are inherently less likely to injure body tissues and more likely to adapt to biological environments. Awareness of the soft robotic systems under development will help promote clinician involvement in their successful clinical translation. Areas covered: The most advanced soft robotic systems, across the size scale from nano to macro, that have shown the most promise for clinical application in cardiovascular therapy because they offer solutions where a clear therapeutic need still exists...

Introduction Despite being a risk mediator in several observational studies, central apneas are currently orphan of treatment in heart failure. After the neutral effects on survival of two randomized controlled trials (RCTs) based on the use of positive airway pressure (the CANPAP and SERVE-HF trials), two alternative hypotheses have been formulated: 1) Periodic breathing/Cheyne-Stokes respiration (PB/CSR) in HF is protective. Indeed, the Naughton's hypothesis assumes that hyperventilation leads to increased cardiac output, lung volume, oxygen storage and reduced muscle sympathetic nerve activity, while central apnea to respiratory muscle rest and hypoxia-induced erythropoiesis...

Carotid artery stenting (CAS) has recently changed the status in the treatment of the extracranial carotid atheromasic disease. In recent years, evolution in both stents and protection devices as well as in carotid stenting techniques, has resulted in an important reduction in the rate of stroke in patients undergoing CAS procedures. Areas covered: The purpose of this article is reviewing the literature and summarizing the current evidence of the new available materials to underline the importance of the correct choice of the devices during the procedure...

Cardiovascular disease remains the most common cause of death worldwide. Enormous progress in the technology and applicability of percutaneous techniques to treat obstructive coronary heart disease has been made, and the number of percutaneous coronary interventions (PCI) is increasing. Coronary bifurcations are involved in a substantial number of PCIs and despite recent advances, bifurcation PCI remains a challenge in terms of immediate success and long-term outcome. Angiography has a limited capacity for showing important features of the 3 dimensional coronary vessel anatomy, position of stent struts and exact wire positions and is therefore suboptimal for guiding bifurcation PCI...

Improved stent technologies have lead to reduced minimum durations of dual antiplatelet therapy (DAPT) to prevent stent thrombosis. However, the anti-ischemic benefits seen in extended DAPT in both stent and non-stent related lesions have called into question the optimum duration of DAPT after stent placement. Areas covered: We review the evidence for varying durations of DAPT after drug eluting stent placement including for patients on oral anticoagulation; decision tools available for clinicians to optimize patient selection for extended therapy and insight into application of these risk assessment tools in clinical practice...
