Coronary Artery Disease in Adults With Coarctation of Aorta: Incidence, Risk Factors, and Outcomes.

Background Premature coronary artery disease ( CAD ) is common in patients with coarctation of aorta ( COA ), but there are limited data about any direct relationship (or lack thereof) between COA and CAD . We hypothesized that atherosclerotic cardiovascular disease risk factors, rather than COA diagnosis, was the primary determinant of CAD occurrence in patients with COA . Methods and Results This is a retrospective study of 654 COA patients and a control group of 876 patients with valvular pulmonic stenosis and tetralogy of Fallot to determine prevalence and independent risk factors for CAD .

Outcomes of Pregnancy in Patients With Prior Right Ventricular Outflow Interventions.

Background The purpose of this study was to compare the incidence of pregnancy-related adverse outcomes ( PRAO ) between patients with versus without hemodynamically significant right ventricle outflow tract ( RVOT) . Methods and Results This was a retrospective cohort study of all pregnant patients with isolated RVOT lesions undergoing evaluation at the Mayo Clinic, 1990 to 2017. Hemodynamic significance was defined as ≥moderate pulmonary/conduit stenosis (≥3 m/s) and/or ≥moderate regurgitation.

Long-Term Outcomes in Patients With Turner Syndrome: A 68-Year Follow-Up.

Background Turner syndrome ( TS ) is the most common sex chromosome abnormality in women and is associated with increased morbidity and mortality. We describe long-term outcomes in a large cohort of patients with TS . Methods and Results Retrospective review of patients with TS followed at Mayo Clinic Rochester from 1950 to 2017 was performed.

Thoracic Aortic Dissection in Tetralogy of Fallot: A Review of the National Inpatient Sample Database.

Background Thoracic aortic aneurysm is common in patients with tetralogy of Fallot ( TOF ); the incidence of thoracic aortic dissection ( TAD ) is unknown, but generally considered to be uncommon. The purpose of this study was to determine incidence and risk factors for TAD in TOF patients. Methods and Results This work is a retrospective review of the National Inpatient Sample ( NIS ) database for cases of ascending TAD among all hospital admissions in adults with TOF , 2000-2014.

Outcomes of Anticoagulation Therapy in Adults With Tetralogy of Fallot.

Background Available outcomes data for anticoagulation therapy in adults with congenital heart disease ( CHD ) provide assessment of global risk of this therapy for CHD patients (a heterogeneous population), but the risk of complications for the different CHD diagnoses is unknown. The purpose of the study was to describe the indications for anticoagulation, and the incidence and risk factors for major bleeding complication in adults with tetralogy of Fallot. Methods and Results We queried Mayo Adult Congenital Heart Disease (MACHD) database for tetralogy of Fallot patients (aged ≥18 years) that received anticoagulation, 1990-2017.

Low-Gradient Severe Mitral Stenosis: Hemodynamic Profiles, Clinical Characteristics, and Outcomes.

Background Optimal management of patients with severe mitral stenosis ( MS ) and low transmitral gradient is incompletely understood. Methods and Results We examined 101 consecutive patients with severe rheumatic MS (mitral valve area ≤1.5 cm) who underwent balloon valvuloplasty.

Leveraging the Electronic Health Record to Create an Automated Real-Time Prognostic Tool for Peripheral Arterial Disease.

Background Automated individualized risk prediction tools linked to electronic health records ( EHR s) are not available for management of patients with peripheral arterial disease. The goal of this study was to create a prognostic tool for patients with peripheral arterial disease using data elements automatically extracted from an EHR to enable real-time and individualized risk prediction at the point of care. Methods and Results A previously validated phenotyping algorithm was deployed to an EHR linked to the Rochester Epidemiology Project to identify peripheral arterial disease cases from Olmsted County, MN, for the years 1998 to 2011.

Temporary Mechanical Circulatory Support for Refractory Cardiogenic Shock Before Left Ventricular Assist Device Surgery.

Background There are limited data on the role of temporary mechanical circulatory support ( MCS ) devices for cardiogenic shock before left ventricular assist device ( LVAD ) surgery. This study sought to evaluate the trends of use and outcomes of MCS in cardiogenic shock before LVAD surgery. Methods and Results This was a retrospective cohort study from 2005 to 2014 using the National Inpatient Sample (20% stratified sample of US hospitals).

Role of QRS Fragmentation for Risk Stratification in Adults With Tetralogy of Fallot.

Background Patients with tetralogy of Fallot ( TOF ) remain at risk for cardiovascular events despite successful repair. Some of the current risk stratification tools require advanced imaging and invasive studies, and hence are difficult to apply to routine patient care. A recent study showed that QRS fragmentation ( QRS -f) is predictive of mortality in patients with TOF.

Tako-Tsubo Cardiomyopathy in Severe Sepsis: Nationwide Trends, Predictors, and Outcomes.

Background There are limited data on the presentation of Takotsubo cardiomyopathy ( TTC ) in severe sepsis. Methods and Results This was a retrospective cohort study using the National Inpatient Sample database (2007-2013) of all adults with severe sepsis. TTC was identified in patients with severe sepsis using previously validated administrative codes.
