Background: Intraplaque delivery of contrast has been utilized during percutaneous coronary interventions (PCI) of chronic total occlusions (CTO) to delineate anatomy and to facilitate wire crossing. Its utility as a tool to accomplish primary crossing of CTOs has not been described or validated.

Aims: We describe a new technique leveraging the diagnostic and therapeutic roles of intraplaque contrast injection to accomplish primary crossing of CTOs: HydroDynamic contrast Recanalization (HDR).

Background: Point of care ultrasound (POCUS) is an imaging technique performed bedside. To date, few published studies have reported the usefulness of multiorgan POCUS in Geriatrics. The objective of this study was to describe the utility of multiorgan POCUS in the care of older adults admitted to geriatric care settings.

The execution of delay-aware applications can be effectively handled by various computing paradigms, including the fog computing, edge computing, and cloudlets. Cloud computing offers services in a centralized way through a cloud server. On the contrary, the fog computing paradigm offers services in a dispersed manner providing services and computational facilities near the end devices.

Background And Aims: Coronary flow capacity (CFC) is associated with an observed 10-year survival probability for individual patients before and after actual revascularization for comparison to virtual hypothetical ideal complete revascularization.

Methods: Stress myocardial perfusion (mL/min/g) and coronary flow reserve (CFR) per pixel were quantified in 6979 coronary artery disease (CAD) subjects using Rb-82 positron emission tomography (PET) for CFC maps of artery-specific size-severity abnormalities expressed as percent left ventricle with prospective follow-up to define survival probability per-decade as fraction of 1.0.

Objective: The objective of this study is to explore the role of adjunctive percutaneous revascularization of the hand in the management of patients with systemic sclerosis-associated refractory digital ischemia.

Methods: We present our initial experience of using percutaneous upper extremity interventions to treat patients with systemic sclerosis and symptomatic Raynaud's phenomenon who presented with either refractory digital ischemia or non-healing ulcers. We discuss patient characteristics, procedural findings, and short-term clinical outcomes of these interventions.

We present the case of a young woman with systemic sclerosis (SSc) and refractory digital ulceration who was successfully treated with percutaneous revascularization of chronically occluded ulnar and radial arteries. To our knowledge, this is the first detailed report of limb salvage in SSc-induced hand ischemia in which contemporary endovascular techniques were used. ().

It is unknown whether endovascular intervention (EVI) is associated with superior outcomes when compared with surgical revascularization in octogenarian. National Inpatient Sample (NIS) database was used to compare the outcomes of limb revascularization in octogenarians who had surgical revascularization versus EVI. The NIS database's information on PAD patients ≥80-year-old who underwent limb revascularization between 2002 and 2014 included 394,504 octogenarian patients, of which 184,926 underwent surgical revascularization (46.

Atrial fibrillation (AF) is associated with an increased risk of dementia. Studies have shown the beneficial effects of anticoagulants in preventing dementia in this population. However, evidence around the use of direct oral anticoagulants (DOACs) versus warfarin in AF-related dementia prevention remains sparse.

Background: Out-of-hospital cardiac arrest (OHCA) is associated with high mortality. Current methods for predicting mortality post-arrest require data unavailable at the time of initial medical contact. We created and validated a risk prediction model for patients experiencing OHCA who achieved return of spontaneous circulation (ROSC) which relies only on objective information routinely obtained at first medical contact.

Acute kidney injury (AKI) is a common complication of percutaneous coronary interventions (PCI), and it is associated with increased morbidity, mortality, and healthcare costs. Post-PCI AKI is a major quality outcome measured by the National Cardiovascular Data Registry for hospitals that perform PCI. We report the experience of a large, tertiary center with high standardized, post-PCI AKI rates in which we implemented multilevel interventions that included: (1) a multidisciplinary education module for all personnel involved in care of patients undergoing cardiac angiography, (2) a standardized electronic medical record based preprocedure hydration protocol order set for patients undergoing cardiac angiography, and (3) a hydration task list to be completed by the care team the evening before the procedure or prior to admission.

The impact of atrial fibrillation (AF) on clinical outcomes among patients with peripheral artery disease (PAD) who undergo limb revascularization procedures is not well understood. We aim to compare in-hospital outcomes for patients with and without AF who underwent limb revascularization. We identified patients with PAD aged ≥18 years that underwent limb revascularization using endovascular or surgical approaches in the National Inpatient Sample between 2002 and 2014.

Background: Acute influenza infection can trigger acute myocardial infarction, however, outcome of patients with acute myocardial infarction during influenza infection is largely unknown.

Methods: Patients ≥18 years old with ST-elevation and non-ST-elevation myocardial infarction during January 2013-December 2014 were identified using the National Inpatient Sample. The clinical outcomes were compared among patients who had no respiratory infection to the ones with influenza and other viral respiratory infections using propensity score-matched analysis.

Reversed pulsus paradoxus was first described in 1973 as a rise in peak systolic pressure on inspiration in patients with idiopathic hypertrophic subaortic stenosis or isorhythmic ventricular rhythm and in patients with left ventricular systolic dysfunction on positive pressure ventilation. Positive pressure ventilation, for example, may impel blood from the pulmonary capillaries and venules into the left atrium. This may increase left ventricular preload and accelerate ventricular emptying, which in turn may cause the systolic arterial pressure to rise during inspiration.

The use of vascular endothelial growth factor inhibitors such as sorafenib is limited by a risk of severe cardiovascular toxicity. A 28-year-old man with acute myeloid leukemia treated with prednisone, tacrolimus, and sorafenib following stem cell transplantation presented with severe bilateral lower extremity claudication. The patient was discharged against medical advice prior to finalizing a cardiovascular evaluation, but returned 1 week later with signs suggestive of septic shock.

Background: The Society of Thoracic Surgery (STS) risk score serves as an important determinant of eligibility for transcatheter aortic valve replacement (TAVR). The STS score's validity for predicting TAVR mortality, however, is incompletely understood. This study compares the STS score's discriminatory power for TAVR mortality as compared with surgical aortic valve replacement (SAVR) mortality.

Objective: The objective of this study was to evaluate safety, efficacy, and durability of coil embolization of the major septal perforator of the left anterior descending coronary artery in patients with hypertrophic obstructive cardiomyopathy (HOCM).

Background: The long-term effect of coil embolization therapy in HOCM patients is not well defined.

Methods: We evaluated 24 symptomatic HOCM patients in a single center who underwent coil embolization of the septal perforator artery(ies).

Objectives: We investigated whether prehospital, reduced dose fibrinolysis coupled with urgent percutaneous coronary intervention (FAST-PCI) reduces mortality and cardiac magnetic resonance (CMR) measures of infarct size, compared with primary percutaneous coronary intervention (PPCI), in patients with ST-elevation myocardial infarction (STEMI).

Background: Current standard therapy for STEMI is PPCI. However, FAST-PCI may shorten ischemic time (IT) and improve outcomes.

Background: Current guidelines for ST-elevation myocardial infarction (STEMI) recommend early revascularization with optimal ischemic time (IT) < 120 min and door-to-balloon (D2B) time < 90 min. The focus of most studies has been D2B time, while IT is not frequently reported. We tested the hypothesis that total IT is a better predictor than D2B time for mortality and infarct size.
