The Perceval sutureless valve resulted in low 1-year event rates in intermediate-risk patients undergoing AVR. New York Heart Association class improved in more than three-quarters of patients and remained stable. These data support the safety and efficacy to 1 year of the Perceval sutureless valve in this intermediate-risk population.

Aims: Mortality in cardiogenic shock patients remains high. Short-term mechanical circulatory support with Impella can be used to support the circulation in these patients, but data from randomised controlled studies and ‘real-world’ data are sparse. The aim is to describe real-life data on outcomes and complications of our 12 years of clinical experience with Impella in patients with cardiogenic shock after acute myocardial infarction and to identify predictors of 6-month mortality. Methods: We describe a single-centre registry from October 2004 to December 2016 including all patients treated with Impella for cardiogenic shock after acute myocardial infarction. We report outcomes and complications and identify predictors of 6-month mortality. Results: Our overall clinical experience consists of 250 patients treated with Impella 2.5, Impella CP or Impella 5.0. A total of 172 patients received Impella therapy for cardiogenic shock, of which 112 patients had cardiogenic shock after acute myocardial infarction. The mean age was 60.1±10.6 years, mean arterial pressure was 67 (56–77) mmHg, lactate was 6.2 (3.6–9.7) mmol/L, 87.5% were mechanically ventilated and 59.6% had a cardiac arrest before Impella placement. Overall 30-day mortality was 56.2% and 6-month mortality was 60.7%. Complications consisted of device-related vascular complications (17.0%), non-device-related bleeding (12.5%), haemolysis (7.1%) and stroke (3.6%). In a multivariate analysis, pH before Impella placement is a predictor of 6-month mortality. Conclusions: Our registry shows that Impella treatment in cardiogenic shock after acute myocardial infarction is feasible, although mortality rates remain high and complications occur.

Background-Myocardial injury is a common complication during cardiac surgery and percutaneous coronary intervention and is associated with postprocedural cardiovascular morbidity and mortality. Limited data have been reported about the occurrence of myocardial damage associated with transcatheter aortic valve implantation (TAVI). Therefore, our purpose was to investigate the incidence, predictors, and prognostic value of myocardial injury during TAVI. Methods and Results-We studied 119 patients (aged 81Ϯ8 years; 47 male) who had undergone a TAVI with the Medtronic-CoreValve bioprosthesis. Serum creatine kinase-MB (CK-MB) and cardiac troponin T (cTnT) levels were measured before and after the procedure. Myocardial injury was defined as a postprocedural increase of CK-MB and/or cTnT level Ͼ5 times the upper reference limit. After TAVI, the incidence of myocardial injury was 17%, which was independently predicted by procedural duration (in minutes) (odds ratio
