AI Article Synopsis
- The study focuses on the implantation of sutureless 3f Enable prostheses in patients with Sievers type 0 bicuspid valves between 2011 and 2014.
- Five patients were selected based on specific criteria, excluding those with larger aortic annulus sizes or lower left ventricle ejection fractions.
- The results showed that two patients developed moderate paravalvular leakages after receiving larger prostheses, highlighting concerns about the valve's performance in this patient group, particularly regarding the acceptance of any residual leakage during surgery.
Article Abstract
Aim: We describe a series of 3f Enable sutureless prostheses implanted in bicuspid valves.
Methods: Between March 2011 and April 2014, five patients with Sievers type 0 bicuspid valves were selected to receive the sutureless 3f Enable prosthesis . Exclusion criteria were: intraoperative calibration of the aortic annulus >27 mm, left ventricle ejection fraction <50%, age <70 years.
Results: All the implantations could be performed without the necessity to re-deploy the prosthesis . The perioperative transesophageal echocardiogragram detected two moderate paravalvular leakages (PVL) in two patients who received a large size of prosthesis (25 and 27 mm, respectively). The two leakages, at a follow-up of 32 and 24 months, respectively, increased to grade II and II +. No PVL appeared in the other three patients.
Conclusion: This experience should warn about the inadequate performance of the 3f Enable valve in Sievers type 0 large aortic bicuspid annuli. In this subset any minor intraoperative residual leakage should not be accepted.

Article Synopsis
- Balloon-expandable valves (BEVs) and self-expanding valves (SEVs) are compared for their effects on patients with Sievers type 1 bicuspid aortic valve (BAV) stenosis undergoing transcatheter aortic valve replacement.
- The analysis, based on a registry of 955 patients, found no significant difference in midterm major adverse events or technical success between BEVs and SEVs after adjusting for baseline differences.
- However, BEVs had lower risks of new permanent pacemaker implantation and moderate or greater paravalvular regurgitation, but a higher risk of severe patient-prosthesis mismatch compared to SEVs.

Classical Zn-dependent deac(et)ylases play fundamental regulatory roles in life and are well characterized in eukaryotes regarding their structures, substrates and physiological roles. In bacteria, however, classical deacylases are less well understood. We construct a Generalized Profile (GP) and identify thousands of uncharacterized classical deacylases in bacteria, which are grouped into five clusters.

Article Synopsis
- This study investigates the outcomes of rapid-deployment aortic valve replacement (RD AVR) in patients with bicuspid aortic valves (BAV) compared to those with tricuspid aortic valves (TAV), aiming to fill the gap in existing research.
- The analysis included 80 patients, with 30 undergoing RD AVR; 16 had TAV and 14 had BAV, allowing for a thorough comparison of preoperative and postoperative outcomes.
- Results showed significant differences in postoperative pressure gradients favoring the BAV group, with no severe complications reported, although one BAV patient required a pacemaker, indicating generally good safety and feasibility for BAV patients undergoing RD AVR.

CIC fusions have been described in two different central nervous system (CNS) tumor entities. On one hand, fusions of CIC or ATXN1 genes belonging to the same complex of transcriptional repressors, were reported in the CIC-rearranged, sarcoma (SARC-CIC). The diagnosis of this tumor type, which was recently added to the World Health Organization (WHO) Classification of CNS tumors, is difficult mainly because the data concerning its histopathology (as compared to its soft tissue counterpart), immunoprofile, and clinical as well as radiological characteristics are scarce in the literature.

Article Synopsis
- The study examines the characteristics and outcomes of patients with tapered raphe-type bicuspid aortic valve (BAV) when undergoing trans-catheter aortic valve replacement (TAVR), focusing on the safety and effectiveness of modern heart valves.
- Researchers analyzed data from 897 patients, finding that those with tapered configurations showed similar success rates and safety between two sizing strategies: annular and supra-annular.
- The results indicate that TAVR is a safe and effective procedure for these patients, regardless of the sizing method used, maintaining a high rate of clinical efficacy at mid-term follow-up.
