Clinical and echocardiographic outcomes of transcatheter mitral valve repair in atrial functional mitral regurgitation.

Background: Isolated atrial fibrillation can cause mitral regurgitation (MR) in patients with normal left ventricular systolic function and no organic disease of the mitral valve. Little information is available regarding outcomes of Mitraclip in patients with atrial functional mitral regurgitation (AFMR). We aimed to evaluate 12-month clinical and echocardiographic outcomes of transcatheter mitral valve repair (TMVR) with MitraClip in patients with AFMR compared to those with ventricular functional or degenerative/mixed MR.

Prognostic Role of TAPSE to PASP Ratio in Patients Undergoing MitraClip Procedure.

Background: Transcatheter mitral valve repair (TMVR) is an effective therapy for high-risk patients with severe mitral regurgitation (MR) but heart failure (HF) readmissions and death remain substantial on mid-term follow-up. Recently, right ventricular (RV) to pulmonary arterial (PA) coupling has emerged as a relevant prognostic predictor in HF. In this study, we aimed to assess the prognostic value of tricuspid annular plane systolic excursion (TAPSE) to PA systolic pressure (PASP) ratio as a non-invasive measure of RV-to-PA coupling in patients undergoing TMVR with MitraClip (Abbott, CA, USA).

Percutaneous Mitral Valve Repair: Outcome Improvement with Operator Experience and a Second-Generation Device.

Background And Aim: Recent randomized data comparing percutaneous mitral valve repair (PMVR) versus optimal medical treatment in patients with functional MR (FMR) seemed to highlight the importance of the learning curve not only for procedural outcomes but also for patient selection. The aim of the study was to compare a contemporary series of patients undergoing PMVR using a second-generation Mitraclip device (Mitraclip NT) with previous cohorts treated with a first-generation system.

Methods: This multicenter study collected individual data from 18 centers between 2012 and 2017.

Transcatheter mitral repair according to the cause of mitral regurgitation: real-life data from the Spanish MitraClip registry.

Introduction And Objectives: Transcatheter mitral valve repair (TMVR) with MitraClip is a therapeutic option for high surgical risk patients with severe mitral regurgitation (MR). The main objective of this study was to analyze differences in outcomes in patients with severe MR according to the cause of MR.

Methods: Observational, multicenter, and prospective study with consecutive patient inclusion.

Incidence and outcome of peri-procedural transcatheter heart valve embolization and migration: the TRAVEL registry (TranscatheteR HeArt Valve EmboLization and Migration).

Aims: Peri-procedural transcatheter valve embolization and migration (TVEM) is a rare but potentially devastating complication of transcatheter aortic valve implantation (TAVI). We sought to assess the incidence, causes, and outcome of TVEM in a large multicentre cohort.

Methods And Results: We recorded cases of peri-procedural TVEM in patients undergoing TAVI between January 2010 and December 2017 from 26 international sites.

Significant transaortic gradient after direct flow aortic valve implantation.

A patient with severe aortic valve disease and high surgical risk underwent Direct Flow (DF) valve implantation. Anatomical assessment (Trans-esophageal echocardiography (TEE) and CT scan) revealed a 3-leaflet aortic valve (annulus diameter 23.4 mm) that was functionally bicuspid because of complete and linearly calcified fusion of noncoronary and right cusps.

Management of ST-elevation myocardial infarction according to European and American guidelines.

Aims: To highlight differences between the most recent guidelines of the European Society of Cardiology (ESC) and the American College of Cardiology Foundation/American Heart Association (ACCF/AHA) on the management of ST-elevation myocardial infarction (STEMI).

Methods And Results: ESC 2012 and ACCF/AHA 2013 guidelines on the management of STEMI were systematically reviewed for consistency. Recommendations were matched, directly compared in terms of class of recommendation and level of evidence, and classified as "identical", "overlapping", or "different".

[Atrioventricular conduction disturbances after CoreValve(®) aortic prosthesis implantation. Predictive role of transesophageal echocardiography].

Atrioventricular conduction disorders can appear after the implantation of percutaneous aortic CoreValve(®) prostheses in patients requiring permanent pacemakers (40%-45% of these patients). The aim of our study was to detect if 2- or 3-dimensional echocardiographic variables could predict the appearance of atrioventricular conduction disorders. For this purpose, the relationship of the prosthesis with the interventricular septum was studied in 26 consecutive patients.

Acute left ventricle diastolic function improvement after transcatheter aortic valve implantation.

Aims: Data regarding the effects of TAVI on LV after are scarce and conflicting results have been reported immediately after aortic valvuloplasty. This study aimed to determine the acute haemodynamic effects of transcatheter aortic valve implantation (TAVI) in left ventricle (LV) diastolic performance, immediately after aortic valvuloplasty and prosthesis deployment.

Methods And Results: Sixty-one patients with severe aortic valve stenosis, and preserved LV systolic function submitted to successful TAVI, were included.

Quality of life improvement at midterm follow-up after transcatheter aortic valve implantation.

Background: Transcatheter aortic valve implantation (TAVI) techniques have been presenting good procedural success and favorable clinical outcomes. However, optimal management of aortic valve disease in elderly patients depends on quality of life (QoL) improvement. In this study we aimed to evaluate changes in QoL in patients referred for TAVI.

Findings of a mixed transfemoral aortic valve implantation program using Edwards and CoreValve devices.

Introduction And Objectives: Transfemoral implantation of an Edwards SAPIEN (ES) or Medtronic CoreValve (MCV) aortic valve prosthesis is an alternative to surgical replacement for patients with severe aortic stenosis and a high surgical risk. The study's aim was to compare results obtained with these two devices.

Methods: Prospective observational study of transfemoral prosthesis implantation performed at our center.

Diagnosis and treatment of coronary stent entanglement complicated by extreme stent distortion.

A 2.5 x 32 mm Taxus Libert e stent was deployed at high pressure in the proximal right coronary artery (RCA) of a 71-year-old male patient, but the distal part of the lesion remained uncovered. A second stent (Driver 2.

[Myocardial infarction with ST segment elevation and angiographically normal coronary arteries: epidemiology and mid-term follow-up].

Background And Objective: The myocardial infarction (MI) with ST elevation and angiographically normal coronary arteries isn't frequent. The aim of this study is to describe clinical characteristic and mid-term follow-up of those patients.

Patients And Method: Between January 1997 and December 2004 we identified 75 patients with MI and normal coronary arteries in a coronary angiography performed within one month of the AMI.

Real-time three-dimensional echocardiography in aortic stenosis: a novel, simple, and reliable method to improve accuracy in area calculation.

Aims: The aim of the study was to validate a novel formula for aortic area, based on the principle of continuity equation (CE), that substitutes Doppler-derived stroke volume (SV) by SV directly measured with real-time three-dimensional (RT3D) echo and semi-automated border detection. RT3D has proved outstanding accuracy for left ventricular volume calculation. So far, however, neither this potential has been applied to haemodynamic assessment, nor RT3D has succeeded in the evaluation of aortic valve disease.

[Interventional cardiology 2006].

The range of applications of percutaneous coronary intervention (PCI) continues to expand and a growing number of patients are being treated, including those with extensive cardiovascular disease, more serious comorbid conditions, and more complex lesions. Even so, the success rate is high, serious complications are rare in stable patients, and the restenosis rate has been dramatically reduced by drug-eluting stents. Nevertheless, percutaneous techniques still have major limitations restricting their use in some type of lesions, such as bifurcations and total occlusions, and their role in relation to surgical revascularization has not yet been well defined in the treatment of the left main coronary artery or multivessel disease.

[Implications of late expansion of self-expanding stents on neointimal response: a serial study with intravascular ultrasound].

Introduction And Objectives: A unique property of self-expanding stents is the continuous force exerted against the vessel wall, which may induce additional arterial damage with implications on restenosis. The main purpose of this study is to evaluate the consequences of late self-expansion of coronary Wallstents.

Methods: Eleven patients with Wallstents implanted in native coronary arteries, in whom baseline, post-stenting, after high pressure balloon inflation and at 6-month follow-up intravascular ultrasound were performed.
