Patients with type B aortic dissection (TBAD) often present as an emergency. Operative repair of TBAD can be indicated for selected patients in the setting of hemodynamic instability or rupture. Thoracic endovascular aortic repair of TBAD has achieved significant popularity. Variant aortic arch anatomy can present a significant clinical challenge in patients with an inadequate proximal landing zone for thoracic endovascular aortic repair. A three-stage, hybrid aortic arch debranching and endovascular repair of a ruptured TBAD in a patient with a bicarotid trunk and an aberrant right subclavian artery was successfully performed using a unique technical approach.

Background: There is a paucity of data on readmission rates and predictors of readmissions in cardiogenic shock patients after contemporary Extracorporeal Membrane Oxygenation (ECMO) use. Methods: Using the Nationwide Readmission Database, we included adult patients (≥18 years old) hospitalized between January to November 2016–2018 for cardiogenic shock requiring ECMO support. Thirty-day readmission rates, associated variables, and predictors of readmission were assessed. Results: A total of 10,723 patients underwent ECMO for cardiogenic shock. After excluding patients who died (n = 5602; 52%) and who underwent LVAD or OHT during index admission (n = 892; 8%), 4229 patients discharged alive were included. Of those, 694 (16.4%) were readmitted within 30 days. The median time to readmission was 10 days. Diabetes mellitus (OR = 1.77; 95% CI 1.32–2.37), chronic liver disease (OR = 1.35; 95% CI 1.03–1.77), and prolonged LOS (≥30 days; OR = 1.38; 95% CI 1.05–1.81) were associated with increased risk of 30-day readmissions while heart failure diagnosis (OR = 0.69; 95% CI 0.50–0.95) and short-term hospital post-discharge care (OR = 0.53; 95% CI 0.28–0.99) conferred a lower risk. Sepsis, followed by congestive heart failure, was the most common readmission diagnoses. Conclusions: Patients with CS requiring ECMO support have high mortality and high 30-day readmission rates, with sepsis being the leading cause of readmissions followed by heart failure.

Objective: To assess the influence of body-mass index (BMI) on the association of ankle-brachial index (ABI) with mortality. Patients and Methods: We conducted a prospective study of National Health and Nutrition Examination Survey participants enrolled from January 1, 1999 to December 31, 2002 with BMI and ABI data available. ABI categories were 1.3 (high). BMI categories were

Background: Cholesterol management guidelines from the American College of Cardiology/American Heart Association (ACC/AHA-2013) recommend fixed statin dosing (dose depends on age ≤ or >75 years) compared to the earlier adult treatment panel III (ATPIII) guidelines which recommended specific low-density lipoprotein-cholesterol (LDL-C) targets. Clinical implications of this recommendation are not known. Methods: We retrospectively compared cholesterol levels and statin utilization across cohorts with coronary artery disease (CAD) (n = 9563), peripheral arterial disease (PAD) (n = 596) and CAD + PAD (n = 975) by applying both guidelines. The percentage of patients who achieved guideline-specific targets using 2013 ACC/AHA (use of moderate/high intensity statins) or ATPIII guidelines (LDL-C 100 mg/dl. Conclusions: Application of the ACC/AHA guidelines results in a higher percentage of patients considered to be ‘at goal’ when compared to the ATP III guidelines without changes in clinical practice. This is due to patients ≤75 years old on adequate statin doses but still have LDL-C levels >100 mg/dl, thereby raising concerns that physicians may not pursue alternate LDL reduction strategies since they are now considered at goal despite LDL-C >100 mg/dl. Lipid management of PAD patients remains sub-optimal as compared to CAD and CAD + PAD.

Objective: To examine the effect of cigarette smoking (CS) status and total testosterone (TT) levels after testosterone replacement therapy (TRT) on all-cause mortality, myocardial infarction (MI), and stroke in male smokers and nonsmokers without history of MI and stroke. Participants and Methods: Data from 18,055 males with known CS status and low TT levels who received TRT at the Veterans Health Administration between December 1, 1999, and May 31, 2014, were grouped into (1) current smokers with normalized TT, (2) current smokers with nonnormalized TT, (3) nonsmokers with normalized TT, and (4) nonsmokers with nonnormalized TT. Combined effect of CS status and TT level normalization after TRT on all-cause mortality, MI, and stroke was compared using propensity score–weighted Cox proportional hazard models. Results: Normalization of serum TT levels in nonsmokers was associated with a significant decrease in all-cause mortality (hazard ratio [HR]=0.526; 95% CI, 0.477-0.581; P
