As the use of transcatheter aortic valve implantation (TAVI) expands to varying patient populations, impacting the landscape of surgical aortic valve replacement (SAVR), this study sought to assess volume and performance trends of aortic valve replacement (AVR) in the United States during 2012-2017. The Nationwide Readmissions Database was queried for patients who underwent endovascular/transapical TAVI, isolated SAVR, or complex aortic valve surgery between 2012 and 2017. Temporal trends in annual case volume, admission costs, in-hospital outcomes, and 30-day readmission were evaluated. ⋯ Patients who underwent AVR demonstrated significant improvements in mortality, stroke, duration of hospitalization, and 30-day readmission. In conclusion, this large contemporary analysis reports the considerable growth of AVR in the United States. It remains unequivocal that the treatment of aortic stenosis is improving overall with reduced mortality following AVR, highlighting the effectiveness of various process improvements such as newer valves, enhanced patient selection, and the interdisciplinary Heart Team approach.

Review Meta Analysis
Meta-analysis Comparing Outcomes in Patients With and Without Cardiac Injury and Coronavirus Disease 2019 (COVID 19).
Current evidence is limited to small studies describing the association between cardiac injury and outcomes in patients with coronavirus disease 2019 (COVID-19). To address this, we performed a comprehensive meta-analysis of studies in COVID-19 patients to evaluate the association between cardiac injury and all-cause mortality, intensive care unit (ICU) admission, mechanical ventilation, acute respiratory distress syndrome, acute kidney injury and coagulopathy. Further, studies comparing cardiac biomarker levels in survivors versus nonsurvivors were included. ⋯ However, cardiac injury was not associated with increased risk of acute respiratory distress syndrome (RR:3.22; 95% CI:0.72 to 14.47; I2 = 73%) or acute kidney injury (RR: 11.52, 95% CI:0.03 to 4,159.80; I2 = 0%). The levels of hs-cTnI (MD:34.54 pg/ml;95% CI: 24.67 to 44.40 pg/ml; I2 = 88%), myoglobin (MD:186.81 ng/ml; 95% CI: 121.52 to 252.10 ng/ml; I2 = 88%), NT-pro BNP (MD:1183.55 pg/ml; 95% CI: 520.19 to 1846.91 pg/ml: I2 = 96%) and CK-MB (MD:2.49 ng/ml;95% CI: 1.86 to 3.12 ng/ml; I2 = 90%) were significantly elevated in nonsurvivors compared with survivors with COVID-19 infection. The results of this meta-analysis suggest that cardiac injury is associated with higher mortality, ICU admission, mechanical ventilation and coagulopathy in patients with COVID-19.

Review Meta Analysis
Meta-analysis Evaluating the Utility of Colchicine in Secondary Prevention of Coronary Artery Disease.
Colchicine has shown potential therapeutic benefits in cardiovascular conditions owing to its broad anti-inflammatory properties. Here, we performed a meta-analysis to determine the efficacy and safety of colchicine in patients with coronary artery disease (CAD). A systematical search in electronic databases of PubMed, The Cochrane Library, and Scopus were carried out to identify eligible studies. ⋯ Colchicine treatment also decreased the risk of myocardial infarction (RR 0.73, 95% CI 0.55 to 0.98), coronary revascularization (RR 0.61, 95% CI 0.42 to 0.89) and stroke (RR 0.47, 95% CI 0.28 to 0.81) in CAD patients, but with no impact on cardiovascular mortality. In addition, the rates of common adverse events were generally similar between colchicine and control groups, including noncardiovascular deaths (RR 1.50, 95% CI 0.93 to 2.40) and gastrointestinal symptoms (RR 1.05, 95% CI 0.91 to 1.22). In conclusion, the results of our meta-analysis demonstrated that colchicine treatment may reduce the risk of future cardiovascular events in CAD patients.

Patients with the Turner syndrome (TS) often have longer QT intervals compared with age-matched peers although the significance of this remains unknown. We sought to determine the degree, frequency and impact of QTc prolongation in patients with TS. A chart review of all patients with an electrocardiogram (ECG) and genetically proven TS was performed. ⋯ QTc was significantly shorter in matched controls using either Bazett or Hodges formula (424 ± 16 ms vs 448 ± 28 ms, p <0.0001; and 414.8 ± 16 ms vs 424.2 ± 20 ms; p = 0.0002, respectively). However, there was no difference in the frequency of QTc prolongation >460 msec (2.8% vs 2.6%, p = 0.9). In conclusion, despite frequent use of QT-prolonging medications, ventricular arrhythmias are rare in TS.

Observational Study
Usefulness of Elevated Troponin to Predict Death in Patients With COVID-19 and Myocardial Injury.
Elevations in troponin levels have been shown to predict mortality in patients with coronavirus disease 2019 (COVID-19). The role of inflammation in myocardial injury remains unclear. We sought to determine the association of elevated troponin with mortality in a large, ethnically diverse population of patients hospitalized with COVID-19, and to determine the association of elevated inflammatory markers with increased troponin levels. ⋯ Patients with elevated troponin had significantly increased odds of death for mildly elevated compared with normal troponin (adjusted OR, 2.06; 95% confidence interval, 1.68 to 2.53; p < 0.001) and for severely elevated compared with normal troponin (OR, 4.51; 95% confidence interval, 3.66 to 5.54; p < 0.001) independently of elevation in inflammatory markers. In conclusion, patients hospitalized with COVID-19 and elevated troponin had markedly increased mortality compared with patients with normal troponin levels. This risk was independent of cardiovascular co-morbidities and elevated markers of inflammation.
