Percutaneous mechanical circulatory support (pMCS) devices are commonly being utilized for hemodynamic support in patients undergoing high-risk percutaneous coronary interventions or stabilization for those in cardiogenic shock. Left ventricular (LV) to ascending aorta (Ao) rotodynamic pumps such as the Impella devices allow for rapid hemodynamic stabilization or support in such instances. The use of such devices is contraindicated in patients with known LV thrombus. However, it remains unclear on how to manage patients who develop an LV thrombus while on prolonged Impella support. While there are currently no cerebral embolic protection devices (CEPDs) approved for use in conjunction with LV to Ao pMCS devices or other short-term mechanical support devices, there is a theoretical benefit for the use of such technology in the right circumstances. We present a case describing the use of the sentinel cerebral protection system (SCPS) in a patient who developed LV thrombus while on Impella CP support. The use of the SCPS in this patient suggests a potential role for CEPD in prevention of thromboembolism while on Impella support.

Comparison of a pulsatile and a continuous flow left ventricular assist device in high-risk PCI.

Authors:
Alexander Samol Marcus Wiemer Sven Kaese

Int J Cardiol 2022 May 18. Epub 2022 May 18.

Department of Cardiology and Intensive Care Medicine, Johannes Wesling University Hospital, Ruhr University Bochum, Minden, Germany.

Background: Mechanical circulatory support devices are able to generate additional cardiac output or maintain sufficient circulation during high-risk PCI. We prospectively compared the hemodynamic and clinical performance of the new iVAC2L® device with the Impella 2.5® device during high-risk PCI. Read More

Thrombosed stuck mitral valve during advanced mechanical circulatory support for post-cardiotomy shock.

Yoshiyuki Takami Naoki Hoshino Hiroshi Ishikawa Kiyotoshi Akita Yusuke Sakurai Kentaro Amano Hideo Izawa Yasushi Takagi

J Cardiol Cases 2022 May 16;25(5):282-284. Epub 2021 Dec 16.

Department of Cardiovascular Surgery, Fujita Health University School of Medicine, Toyoake, Japan.

We report a case of mechanical prosthetic mitral valve thrombosis in a 52-year-old woman with previous diagnosis of dilated cardiomyopathy, who was supported with advanced mechanical circulatory support after urgent mechanical mitral valve replacement (MVR) and tricuspid annuloplasty. Difficult weaning from cardiopulmonary bypass needed support with veno-arterial extracorporeal membranous oxygenation and Impella (Abiomed Inc, Danvers, MA, USA), so-called ECPELLA. Temporary discontinuation of heparin and massive blood transfusion were necessary due to four times of reoperation for bleeding during ECPELLA support. Read More

Circ Cardiovasc Interv 2022 May 17;15(5):e011534. Epub 2022 May 17.

Duke Clinical Research Institute, Duke University Medical Center, Durham, NC (M.Z., G.M.G., P.Z., D.M.W., S.V.R., T.Y.W.).

Background: Mechanical circulatory support (MCS) devices can be used in high-risk percutaneous coronary intervention (PCI). Our objective was to describe trends and outcomes of prophylactic MCS use in elective PCI for patients with stable coronary artery disease in the American College of Cardiology National Cardiovascular Data Registry's CathPCI registry.

Methods: Among 2 108 715 consecutive patients with stable coronary artery disease undergoing elective PCI in the CathPCI registry between 2009 and 2018, we examined patterns of prophylactic use of MCS. Read More

Cardiac power output index to define hemodynamic response to Impella support in cardiogenic shock.

Hoong Sern Lim

Int J Artif Organs 2022 May 16:3913988221100278. Epub 2022 May 16.

Queen Elizabeth Hospital Birmingham, University Hospitals Birmingham NHS Foundation Trust, Birmingham, UK.

Background: Early assessment of response to Impella in cardiogenic shock may guide escalation of mechanical circulatory support. Therapeutic goal and response to Impella have not previously been defined. This study tested the hypothesis that targeting 3-h post- Impella cardiac power output index (CPOi)-"hemodynamic response"-in cardiogenic shock is associated with 12-h lactate clearance. Read More
