Surgical revision after percutaneous mitral valve repair by edge-to-edge device in high-risk patients.

Background: Patients scheduled for surgery after unsuccessful MitraClip® intervention present increasingly with multiple comorbidities, and they are often referred to the heart team to suggest the most appropriate intervention. The publication of successful results of initial patient cohorts treated with the MitraClip device has resulted in recruitment of more seriously ill patients, who otherwise would have been denied catheter-based/surgical treatment. There has been increasingly reports on conventional surgery after failed mitral valve repair with the MitraClip device.

Cardiac magnetic resonance based evaluation of aortic stiffness and epicardial fat volume in patients with hypertension, diabetes mellitus, and myocardial infarction.

Background Aortic stiffness and epicardial fat relate to cardiovascular risk. Their relationship with each other and their role with hypertension, diabetes mellitus (DM), and myocardial infarction (MI) can be evaluated by cardiac magnetic resonance (CMR). Purpose To explore an association between aortic stiffness and epicardial as well as paracardial fat volume (EFV and ParaFV, respectively) in hypertensive patients and to relate the results to the presence of DM and MI.

3D-Dixon cardiac magnetic resonance detects an increased epicardial fat volume in hypertensive men with myocardial infarction.

Purpose: Using a three-dimensional ECG- and respiratory navigator gated magnetization prepared mDixon-sequence (3D-Dixon) we quantified epi- and pericardial fat volumes (EFV, PFV) in hypertensive men compared to a healthy control group and related the amount of fat volumes in hypertensive men to the presence of coronary artery disease (CAD) and myocardial infarction (MI).

Materials And Methods: 55 hypertensive men (mean age 63.02±10.

One-year outcomes after direct transcatheter aortic valve implantation with a self-expanding bioprosthesis. A two-center international experience.

Background: Balloon aortic valvuloplasty (BAV) is considered to be an essential part of the transcatheter aortic valve implantation (TAVI) procedure and is being performed routinely. At present there is insufficient long-term data as to the benefits of routine BAV prior to TAVI.

Aim: The aim of this study was to evaluate the safety of direct TAVI and the mortality rate at 1-year in patients undergoing TAVI with or without BAV with a self-expanding bioprosthesis.

"Device landing zone" calcification, assessed by MSCT, as a predictive factor for pacemaker implantation after TAVI.

Background: After trans-catheter aortic valve implantation (TAVI), the need for postinterventional pacemaker (PM) implantation can occur in as many as 10-50% of cases, but it is not yet clear, how this need can be predicted. The aim of this study was to assess the possible predictive factors of post TAVI PM implantation based on Computed Tomography (CT) measured aortic valve calcification and its distribution.

Methods: We prospectively analyzed 81 consecutive symptomatic patients with severe AS scheduled for TAVI using the CoreValve prosthesis (Medtronic, Minneapolis, USA).

Procedural and mid-term results in patients with aortic stenosis treated with implantation of 2 (in-series) CoreValve prostheses in 1 procedure.

Objectives: This study sought to assess post-procedural and mid-term outcome of patients, in which a second "in-series" CoreValve prosthesis (Medtronic, Minneapolis, Minnesota) was implanted during the same procedure.

Background: Because of the increasing number of patients implanted with CoreValves, the need for management of special complications has emerged. A misplaced prosthesis can be corrected by various maneuvers.

Correlation of Device landing zone calcification and acute procedural success in patients undergoing transcatheter aortic valve implantations with the self-expanding CoreValve prosthesis.

Objectives: The aim of this study was to assess the influence of amount and distribution of calcifications of the aortic valve and the left ventricular outflow tract on the acute procedural outcome of patients undergoing transcatheter aortic valve implantation (TAVI).

Background: Transcatheter aortic valve implantation is a new percutaneous technique especially for elderly, high-risk patients with significant aortic valve stenosis (AS). After TAVI, post-interventional paravalvular aortic regurgitations (PAR) can occur, which is believed to be related partially to valve calcifications.

Computerized two-lead resting ECG analysis for the detection of coronary artery stenosis after coronary revascularization.

Background: Resting electrocardiogram (ECG) shows limited sensitivity and specificity for the detection of coronary artery disease (CAD), where patients with a history of coronary revascularization may pose special challenges. Several methods exist to enhance sensitivity and specificity of resting ECG for diagnosis of CAD, but such methods are not better than a specialist's judgement. We compared a new computer-enhanced, resting ECG analysis device, 3DMP, to coronary angiography to evaluate the device's accuracy in detecting hemodynamically relevant CAD.
