nos: 91 -98 BACKGROUND Portico Ò (St. Jude Medical) and CoreValveÔ (Medtronic) are both nitinol based self-expanding transcatheter heart valves with unique features enabling device retrievability for Portico and supra annular valve position for CoreValve systems. In this study, we sought to investigate the effect of the different self-expanding valve design on hemodynamic and clinical performance when implanted for degenerated aortic valve bioprosthesis (valve in valve, ViV).

A pandemic coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causes a disease called coronavirus disease 2019 (COVID-19), which is potentially life-threatening. Patients with hematologic malignancies may be at an increased risk of severe COVID-19 due to immunosuppression related to the underlying disease and/or its treatment. 1 Sézary syndrome (SS) is a rare leukemic type of primary cutaneous lymphoma, defined by the triad of erythroderma, lymphadenopathy, and clonal T cells in the skin, lymph nodes, and peripheral

the beginning of the procedure, after ballonvalvuloplasty (BAV) and after TAVI. Perioperative concentrations of serum troponin I (TnI) in the first 72h after TAVI were measured for detection of myocardial injury. Results: CVR ( fig. 1) was impaired at baseline (1.59AE0.37) improved after BAV and subsequent valve implantation (1.68AE0.37). Recovery time towards bAPV was longer after the rapid pacing (RP) period during valve implantation than after RP period during BAV (12.94AE16.57s vs. 7.96AE9.67s; p¼0.322). A positive correlation was found between the duration of RP and AUC for perioperative troponin I (p< 0.05).Conclusions: TAVI leads to an improvement in CVR,which may pathophysiologically contribute to attenuation of ischemic symptoms,and a longer RP duration appears to be associated with myocardial injury.
