Prognostic value of biomarkers of ischaemia in patients with peripheral arterial disease following endovascular revascularisation.

Our aim was to evaluate the prognostic value of detectable high-sensitivity cardiac troponin I (hs-cTnI) and ischaemia-modified albumin (IMA) in predicting all-cause death or non-fatal ischaemic events in patients with PAD after endovascular revascularisation of the lower limbs. Patients who underwent successful endovascular revascularisation for chronic limb-threatening ischaemia (CLTI) or disabling intermittent claudication (IC) were prospectively included. Pre-procedural levels of hs-cTnI and IMA were measured, and patients were followed for one year for the occurrence of the composite outcome of all-cause death, non-fatal myocardial infarction, new-onset angina, non-fatal ischaemic stroke, transient ischaemic attack, or progression of PAD.

Type A Aortic Dissection in Heart Transplantation Recipients in the United States.

Background: Type A aortic dissection in heart transplantation recipients is rare and lethal, with limited research beyond case reports. This study aimed to analyze patient characteristics and clinical outcomes of this condition through a US national database.

Methods: The National Inpatient Sample database (2002-2018) was used to identify all type A aortic dissection in heart transplantation recipients aged >18 years.

ECMO as a bridge to cardiac surgery: stabilizing unstable patients for a definitive procedure.

Introduction: Extracorporeal membrane oxygenation (ECMO) in adults has been used in post-cardiotomy patients who decline hemodynamically. Cardiogenic shock in patients with potential surgically correctable cardiac conditions are at significantly higher risk for post-operative morbidity and mortality. We present experience with a pre-emptive approach of ECMO institution pre-operatively to stabilize patients with cardiogenic shock.

Strokes in Patients With Injection Drug Use and Tricuspid Valve Endocarditis - A Case Series.

In this study, we describe patients from a tertiary care safety-net hospital endocarditis registry with tricuspid valve infective endocarditis (TVIE), and concomitant acute or subacute ischemic stroke predominantly associated with injection drug use (IDU). We retrospectively obtained data pertinent to neurologic examinations, history of injection drug use (IDU), blood cultures, transthoracic/transesophageal echocardiography (TTE/TEE), neuroimaging, and Modified Rankin Scale (mRS) scores at discharge. Only those patients with bacteremia, tricuspid valve vegetations, and neuroimaging consistent with acute to subacute ischemic infarction and microhemorrhages in two cases were included in this series.

Aortic Dissection During Pregnancy and Puerperium: Contemporary Incidence and Outcomes in the United States.

Background Aortic dissection (AD) during pregnancy and puerperium is a rare catastrophe with devastating consequences for both parent and fetus. Population-level incidence trends and outcomes remain relatively undetermined. Methods and Results We queried a US population-based health care database, the National Inpatient Sample, and identified all patients with a pregnancy-related AD hospitalization from 2002 to 2017.

Association of Intravenous Drug Use and Length of Stay Following Infective Endocarditis.

Introduction: Intravenous drug use (IVDU) and associated infective endocarditis (IE) has been on the rise in the US since the beginning of the opioid epidemic. IVDU-IE has high morbidity and mortality, and treatment can be lengthy. We aim to quantify the association between IVDU and length of stay (LOS) in IE patients.

Right ventricular wall dissection complicating myocardial infarction.

Right ventricular wall dissection is extremely rare and can result in dismal clinical outcomes. We report a 68-year-old patient who presented with acute myocardial infarction and was found to have right ventricular wall dissection by ventriculography. At surgery, the infarcted myocardium was excised, and a two-patch technique was used to repair the ventricular septal defect.

Surgical outcomes of pulmonary valve infective endocarditis: A US population-based analysis.

Background: Pulmonary valve infective endocarditis (PVIE) represents a rare subset of right-sided IE. This study aimed to evaluate the population-level surgical outcomes of PVIE in the United States.

Methods: We performed a retrospective observational study using the 2002-2017 National Inpatient Sample database.

Sex-based outcomes in surgical repair of acute type A aortic dissection: A meta-analysis and meta-regression.

Objective: Epidemiologic variation with respect to sex has been established in aortic dissection. However, current literature on sex-based outcomes in patients with aortic dissection is conflicting. In this study we aimed to compare perioperative outcomes according to sex in patients treated surgically for acute type A aortic dissection.

Primary Pericardial Mesothelioma: A Population-Based Propensity Score-Matched Analysis.

Primary pericardial mesothelioma is a rare malignancy of the mesothelial lining of the pericardium. This study aimed to evaluate the clinical characteristics and survival outcomes of these patients using a United States population-based cancer database. We queried the Surveillance, Epidemiology, and End Results program (1973-2015).

Liver Dysfunction Associated With In-Hospital Mortality in Adult Extracorporeal Membrane Oxygenation Support.

Unlabelled: Extracorporeal membrane oxygenator support is a powerful clinical tool that is currently enjoying a resurgence in popularity. Wider use of extracorporeal membrane oxygenator support is limited by its significant risk profile and extreme consumption of resources. This study examines the role of markers of liver dysfunction in predicting outcomes of adult patients requiring extracorporeal membrane oxygenator support.

Perivascular Adipose Tissue Inflammation in Ischemic Heart Disease.

Objective: There is growing recognition that adipose tissue-derived proatherogenic mediators contribute to obesity-related cardiovascular disease. We sought to characterize regional differences in perivascular adipose tissue (PVAT) phenotype in relation to atherosclerosis susceptibility. Approach and Results: We examined thoracic PVAT samples in 34 subjects (body mass index 32±6 kg/m, age 59±11 years) undergoing valvular, aortic, or coronary artery bypass graft surgeries and performed transcriptomic characterization using whole-genome expression profiling and quantitative polymerase chain reaction analyses.

Extracorporeal membrane oxygenation in the management of granulomatosis with polyangiitis.

Granulomatosis with polyangiitis (GPA, also known as Wegener's granulomatosis) is a type of systematic vasculitis that primarily involves the lung and kidney. Diffuse alveolar hemorrhage (DAH) and associated acute respiratory failure are uncommon but devastating complications of GPA. Experience in using extracorporeal membrane oxygenation (ECMO) to manage DAH caused by GPA is limited.

Primary cardiac lymphoma.

Objective: This study aimed to understand the population-level treatment modalities and to evaluate the survival benefits of surgical resection in primary cardiac lymphoma.

Methods: We queried the Surveillance, Epidemiology, and End Results Program database, which covers 35% of the US population. Patients with a histologic diagnosis of primary cardiac lymphoma from 1973 to 2015 were included.

Survival outcomes in patients with primary cardiac sarcoma in the United States.

Objective: We aim to evaluate the survival outcomes of primary cardiac sarcoma in a US nationwide cancer database.

Methods: The Surveillance, Epidemiology, and End Results database was queried to identify patients with primary cardiac sarcoma from 1973 to 2015. Kaplan-Meier analysis and log-rank tests were performed to compare overall survival for subpopulations, stratified on year at diagnosis (dichotomized into 2 periods: 1973-2005 and 2006-2015), pathological types, whether patients were treated with surgery or not, and surgery and chemotherapy combinations.

Effect of Publicly Reported Aortic Valve Surgery Outcomes on Valve Surgery in Injection Drug- and Non-Injection Drug-Associated Endocarditis.

Background: Injection drug use-associated infective endocarditis (IDU-IE) is rising and valve surgery is frequently indicated. The effect of initiating public outcomes reporting for aortic valve surgery on rates of valve surgery and in-hospital mortality for endocarditis is not known.

Methods: For an interrupted time series analysis, we used data from the National Inpatient Sample, a representative sample of United States inpatient hospitalizations, from January 2010 to September 2015.
