Multicenter StudyIncidence and predictors of permanent pacemaker implantation following transcatheter aortic valve implantation: analysis from the German transcatheter aortic valve interventions registry.
To determine predictors of permanent pacemaker (PPM) implantation up to 30 days after transcatheter aortic valve implantation (TAVI) in a prospective multicenter registry. ⋯ PPM is a common postprocedure requirement after TAVI. The absence of prior valve surgery, the implantation of Medtronic CoreValve™ prosthesis, and the presence of a porcelain aorta were independently associated with PPM after TAVI.

ReviewState-of-the-art paper: Therapeutic hypothermia in out of hospital cardiac arrest survivors.
Out of hospital cardiac arrest (OHCA) is associated with an extremely poor survival rate, with mortality in most cases being related to neurological injury. Among patients who experience return of spontaneous circulation (ROSC), therapeutic hypothermia (TH) is the only proven intervention shown to reduce mortality and improve neurological outcome. ⋯ While recent technological advances in TH will likely improve outcomes in OHCA survivors, several fundamental questions remain to be answered including the optimal speed of cooling, which patients benefit from an early invasive strategy, and whether technological advances will facilitate application of TH in the field. An increased awareness and understanding of TH strategies, devices, monitoring, techniques, and complications will allow for a more widespread adoption of this important treatment modality.

Case ReportsTranscatheter aortic valve implantation in a patient with mechanical mitral prosthesis: a lesson learned from an intraventricular clash.
We hereby present the case of a patient with severe aortic stenosis who underwent in her previous medical history a mitral valve replacement with a mechanical valve (Omnicarbon 27), and progressively developed a severe aortic stenosis. This patient was judged inoperable and then scheduled for CoreValve Revalving System implantation. Despite a good positioning of the CoreValve, an acute, severe mitral regurgitation developed soon after implantation as a consequence of the impaired movement of the mitral prosthesis leaflet. ⋯ A good mitral prosthesis function was restored disengaging the CoreValve from the aortic annulus. After few months, the patients underwent successful Edwards-Sapien valve implantation through the Corevalve. This case strongly demonstrates how much a careful evaluation of the features of the mitral prosthesis and patient anatomy is crucial to select which specific transcatheter bioprosthesis would better perform.

Comparative Study Observational StudyEmergency and prophylactic use of miniaturized veno-arterial extracorporeal membrane oxygenation in transcatheter aortic valve implantation.
To report our center's experience using veno-arterial extracorporeal membrane oxygenation (vaECMO) in transcatheter aortic valve implantation (TAVI). ⋯ Life-threatening complications during TAVI can be managed using emergency vaECMO but mortality remains high. The use of prophylactic vaECMO in very high-risk patients is safe and may be advocated in selected cases.

Comparative StudySynergistic effect of thrombus aspiration and abciximab in primary percutaneous coronary intervention.
Previous studies failed to assess the individual prognostic role of thrombus aspiration (TA) or abciximab in primary percutaneous coronary intervention (pPCI), due their prevalent combined use. ⋯ The combination of pharmacologic and mechanic antithrombotic treatment during pPCI was associated with better 1-year clinical outcome.
