Background: The management of cardiogenic shock (CS) after ACS has evolved over time, and the development of a multidisciplinary team-based approach has been shown to improve outcomes, although mortality remains high. Methods: All consecutive patients with ACS-CS admitted at our CICU from March 2012 to July 2021 were included in this single-center retrospective study. In 2019, we established a "shock team" consisting of a cardiac intensivist, an interventional cardiologist, an anesthetist, and a cardiac surgeon. The primary outcome was in-hospital mortality. Results: We included 167 patients [males 67%; age 71 (61–80) years] with ischemic CS. The proportion of SCAI shock stages from A to E were 3.6%, 6.6%, 69.4%, 9.6%, and 10.8%, respectively, with a mean baseline serum lactate of 5.2 (3.1–8.8) mmol/L. Sixty-six percent of patients had severe LV dysfunction, and 76.1% needed ≥ 1 inotropic drug. Mechanical cardiac support (MCS) was pursued in 91.1% [65% IABP, 23% Impella CP, 4% VA-ECMO]. From March 2012 to July 2021, we observed a significative temporal trend in mortality reduction from 57% to 29% (OR = 0.90, p = 0.0015). Over time, CS management has changed, with a significant increase in Impella catheter use (p = 0.0005) and a greater use of dobutamine and levosimendan (p = 0.015 and p = 0.0001) as inotropic support. In-hospital mortality varied across SCAI shock stages, and the SCAI E profile was associated with a poor prognosis regardless of patient age (OR 28.50, p = 0.039). Conclusions: The temporal trend mortality reduction in CS patients is multifactorial, and it could be explained by the multidisciplinary care developed over the years. [ABSTRACT FROM AUTHOR]

Background: Aortic valve stenosis is the most common valvular disease in the elderly. Transcatheter aortic valve implantation represents a viable alternative to conventional aortic valve replacement. In our Department, the transapical approach is the preferred method in patients with severe peripheral vascular disease. The aim of this study was to analyze the early and midterm results of Symetis Acurate TA implantation in our series., Methods: From June 2013 to January 2017, 21 patients with severe peripheral vascular disease (11 male, mean age 78 ± 2.8 years) underwent transapical implantation of the Symetis Acurate TA device. Mean logistic EuroSCORE I was 21.9 ± 8.6, mean left ventricular ejection fraction was 51.9 ± 12.2%, and mean aortic gradient was 46.7 ± 12.3 mmHg. Valve implantation was performed through a left anterior minithoracotomy. Patients were followed up on a regular basis. Cardiac echocardiographic assessment was performed at 6 months post-implantation., Results: Valve implantation was successful in all patients. Valve sizes were as follows: 7 size S, 6 size M, and 8 size L. Two patients died before hospital discharge (9.5%). Among survivors, 2 patients showed more than mild aortic regurgitation at discharge. Mean aortic gradient was 13.1 ± 4.3 mmHg (p<0.01). Median follow-up was 11.3 months. Mean NYHA class at follow-up was 1.9 ± 0.4 (p<0.05). Mean actuarial survival was 80%., Conclusions: Our series, even if small, demonstrates that transapical implantation of the Symetis Acurate TA device represents a viable solution in patients with severe peripheral vascular disease carrying a high operative risk. The relatively high operative mortality may be attributable to the learning curve of our team.
