German Experience with a Novel Balloon-Expandable Heart Valve Prosthesis for Transcatheter Aortic Valve Implantation-Outcomes of the MYLAND (MYvaL germAN stuDy) Study.

The primary objective of this study was to evaluate the initial experience in Germany with the Meril Myval™ (MM) transcatheter heart valve (THV) system for the treatment of severe symptomatic aortic valve stenosis. The MM THV is a novel balloon-expandable valve with an expanded sizing matrix. Contemporary patients undergoing TAVI with the established Edwards Sapien™ (ES) THV served as the comparator group.

Comprehensive echocardiographic prediction of postprocedural transmitral pressure gradient following transcatheter mitral valve repair.

Iatrogenic mitral stenosis following transcatheter mitral valve repair (TMVR) for relevant mitral regurgitation (MR) is a potential adverse side-effect, known to affect long-term outcome. However, only few determinants of an elevated mean transmitral pressure gradient (TMPG) have been described thus far. We sought to develop an integrative model for the prediction of TMPG following MitraClip (MC) therapy.

Permanent Pacemaker Implantation Following Valve-in-Valve Transcatheter Aortic Valve Replacement: VIVID Registry.

Background: Permanent pacemaker implantation (PPI) remains one of the main drawbacks of transcatheter aortic valve replacement (TAVR), but scarce data exist on PPI after valve-in-valve (ViV) TAVR, particularly with the use of newer-generation transcatheter heart valves (THVs).

Objectives: The goal of this study was to determine the incidence, factors associated with, and clinical impact of PPI in a large series of ViV-TAVR procedures.

Methods: Data were obtained from the multicenter VIVID Registry and included the main baseline and procedural characteristics, in-hospital and late (median follow-up: 13 months [interquartile range: 3 to 41 months]) outcomes analyzed according to the need of periprocedural PPI.

Benefits of routine prophylactic femoral access during transvenous lead extraction.

Background: The number of patients requiring lead extraction has been increasing in recent years. Despite significant advances in operator experience and technique, unexpected complications may occur. Prophylactic placement of femoral sheaths allows for immediate endovascular access for emergency procedures and may shorten response time in the event of complications.

Transcatheter Mitral Valve Replacement After Surgical Repair or Replacement: Comprehensive Midterm Evaluation of Valve-in-Valve and Valve-in-Ring Implantation From the VIVID Registry.

Background: Mitral valve-in-valve (ViV) and valve-in-ring (ViR) are alternatives to surgical reoperation in patients with recurrent mitral valve failure after previous surgical valve repair or replacement. Our aim was to perform a large-scale analysis examining midterm outcomes after mitral ViV and ViR.

Methods: Patients undergoing mitral ViV and ViR were enrolled in the Valve-in-Valve International Data Registry.

Long-term outcomes after transcatheter aortic valve implantation in failed bioprosthetic valves.

Aims: Due to bioprosthetic valve degeneration, aortic valve-in-valve (ViV) procedures are increasingly performed. There are no data on long-term outcomes after aortic ViV. Our aim was to perform a large-scale assessment of long-term survival and reintervention after aortic ViV.

Successful balloon valvuloplasty of rheumatic mitral valve stenosis in a pregnant patient without fluoroscopy: a case report.

Introduction: Rheumatic mitral stenosis (MS) is the most common rheumatic heart disease that complicates pregnancy. Percutaneous transvenous mitral commissurotomy (PTMC) has become the first-choice treatment, but is routinely performed with fluoroscopic guidance, which bears risks from ionizing radiation for the embryo when performed in pregnant patients.

Case Presentation: A pregnant patient was referred to our department for therapy of severe MS after she suffered from cerebral artery infarction.

Explorative analysis of IPA-SPECT data through statistical inference for an automated diagnosis of glioma tumor.

Purpose: The identification of a brain tumor imaged with PET or SPECT is usually performed with visual inspection of an expert medical clinician. However an automated diagnostic of such images hasn't been established or applied. In this study, we explored the possibility of establishing an automated statistical analysis for the diagnosis of glioma by means of IPA-SPECT data.

Transcatheter Aortic Valve Replacement in Pure Native Aortic Valve Regurgitation.

Background: Limited data exist about safety and efficacy of transcatheter aortic valve replacement (TAVR) in patients with pure native aortic regurgitation (AR).

Objectives: This study sought to compare the outcomes of TAVR with early- and new-generation devices in symptomatic patients with pure native AR.

Methods: From the pure native AR TAVR multicenter registry, procedural and clinical outcomes were assessed according to VARC-2 criteria and compared between early- and new-generation devices.
