High-Sensitivity Cardiac Troponin T Elevation in Hypertrophic Cardiomyopathy Is Associated With Ventricular Arrhythmias.
To investigate the relationship between high-sensitivity cardiac troponin T (hs-cTnT) levels and sudden cardiac death (SCD) in patients with hypertrophic cardiomyopathy (HCM). ⋯ In a protocolized, outpatient HCM population, hs-cTnT elevations were common and were associated with more arrhythmic expressivity of the HCM substrate as indicated by previous ventricular arrhythmias and appropriate implantable cardioverter-defibrillator shocks only when sex-specific hs-cTnT cutoffs were used. Further research should use different hs-cTnT reference values by sex to determine whether an elevated hs-cTnT value is an independent risk factor for SCD in patients with HCM.

Risks of Right Heart Catheterization and Right Ventricular Biopsy: A 12-year, Single-Center Experience.
To study the incidence of complications when undergoing right heart catheterization (RHC) and right ventricular biopsy (RVB). ⋯ Complications following diagnostic RHC and RVB are seen in 21.6 and 20.8 procedures, respectively, of 10,000 procedures and all deaths were secondary to acute illness.
