Randomized Controlled TrialAspiration coronary thrombectomy for acute myocardial infarction increases myocardial salvage: single center randomized study.
The aim of the study was to assess if aspiration thrombectomy in high risk patients with STEMI and angiographic evidence of thrombus may improve myocardial salvage. ⋯ Aspiration thrombectomy improves myocardial salvage in high risk STEMI patients with angiographic evidence of thrombus.

Multicenter StudyThe ability to achieve complete revascularization is associated with improved in-hospital survival in cardiogenic shock due to myocardial infarction: Manitoba cardiogenic SHOCK Registry investigators.
To identify predictors of survival in a retrospective multicentre cohort of patients with cardiogenic shock undergoing coronary angiography and to address whether complete revascularization is associated with improved survival in this cohort. ⋯ The ability to achieve complete revascularization may be strongly associated with improved in-hospital survival in patients with cardiogenic shock.

Influence of CoreValve ReValving System implantation on mitral valve function: an echocardiographic study in selected patients.
The purpose of this study is to verify whether transcatheter aortic valve implantation (TAVI) determined changes in mitral valve (MV) function, in terms of mitral regurgitation (MR) and stenosis. ⋯ In the majority of patients no significant changes occurred in the degree of MR in native valve, but we found that if the aortic valve was deeply implanted in the left ventricle outflow tract, a worsening in MR can be observed. A mitral stenosis development must be sought in patients with heavy calcifications of the anterior leaflet.

Case ReportsPercutaneous treatment of aortic stenosis and mitral regurgitation in the same patient: first human cases description.
Transcatheter valve therapy is becoming an established treatment for aortic stenosis (AS) and it is very promising for mitral regurgitation (MR). There are no formal reports of percutaneous treatment of both AS and MR in the same patient. Here, we report on the first human cases of successful totally percutaneous management of combined severe AS and MR as a planned staged approach and using MitraClip(®) implantation as a procedure necessitated by an unpredictable complication of self-expanding CoreValve device, respectively.

Mid-term follow up of perventricular device closure of muscular ventricular septal defects.
Surgical and transcatheter management of muscular ventricular septal defects (MVSD) have independent drawbacks. Hybrid procedures are becoming increasingly utilized to manage congenital cardiac lesions including MVSDs. This report describes the mid-term results of perventricular device closure of MVSDs at a single institution. ⋯ Perventricular closure of MVSDs is attractive because it overcomes the limitations of surgery and catheterization. Additionally, it spares the need for cardiopulmonary bypass and its comorbidities. In some instances, however, successful deployment of the device is not possible. Our mid-term results demonstrate overall success but identify possible complications that are not immediately identified in the short term.
