The new percutaneous Impella CP (Cardiac Power; Abiomed, Inc., Danvers, MA) was designed to provide a higher level of support than Impella 2.5 (Abiomed, Inc.). We present the first documented case of a patient that was transitioned from the Impella 2.5 to Impella CP. A 48-year-old male patient with no medical history was transferred to our institution with a one day history of worsening shortness of breath. The patient was unstable and found to have monomorphic ventricular tachycardia at 220 beats/min that was cardioverted to normal sinus rhythm...

BACKGROUND: Despite advances in treatment, mortality in acute myocardial infarction complicated by cardiogenic shock remains high. Short-term mechanical circulatory support devices acutely improve hemodynamic conditions. The Impella CP is a new percutaneous circulatory support device that provides more hemodynamic support than the intra-aortic balloon pump (IABP). OBJECTIVES: The aim of this study was to determine whether the Impella CP can decrease 30-day mortality when compared with IABP in patients with severe shock complicating acute myocardial infarction...

INTRODUCTION: Mechanical circulatory support may be considered as a therapeutic option in selected patients with refractory cardiac arrest (rCA). Animal studies suggest a potential role for the Impella(®) left ventricular assist device in this setting, but so far no human data have been published. METHODS: Eight patients with rCA were treated with the Impella CP(®) device at our institution from November 2014 to October 2015. The Impella CP(®) was used at the discretion of the treating physicians in patients with rCA and pulseless electrical activity with presumed primary left ventricular failure...

BACKGROUND: Outcomes of traditional mechanical support paradigms (extracorporeal membrane oxygenation, intraaortic balloon pump [IABP], and permanent left ventricular assist device [LVAD]) in acute decompensated heart failure have generally been suboptimal. Novel approaches, such as minimally invasive LVAD therapy (Impella 5.0 device), promise less invasive but equivalent hemodynamic support. However, it is yet unknown whether the outcomes with such devices support widespread acceptance of this new technology...

The rate of performing primary percutaneous coronary intervention in patients with complex coronary artery disease is increasing. The use of percutaneous mechanical circulatory support devices provides critical periprocedural hemodynamic support. Mechanical support has increased the safety and efficacy of interventional procedures in this high-risk patient population. Predicting patient response to the selected intervention can be clinically challenging. Here we demonstrate a case where complete hemodynamic collapse during PCI was avoided by mechanical support provided by the Impella device...

The catheter-based Impella 5.0 left ventricular assist device is a powerful and less invasive alternative for patients in cardiogenic shock. The use as second-line therapy in patients with precedent extracorporeal life support (ECLS) has not been described before now. We analyzed our experience of consecutive patients treated with this alternative strategy. From April 2014 to December 2014, eight patients had been implanted as a second-line option after ECLS support. The reason for the change from ECLS to Impella 5...

BACKGROUND AND OBJECTIVES: Sufficient cardiac output is one of the main goals of ventricular assist device therapy. To date, there is no adequate method to estimate the combined amount of blood the native heart and a continuous-flow assist device pump through the circulatory system. This paper presents an approach to estimate total cardiac output based on the signals provided by optical pressure sensors mounted on the inlet and outlet of an Abiomed Impella CP pump. METHODS: Two Kalman filters were used in parallel for joint estimation of the aortic flow rate and the hydraulic resistance of the aortic valve...

AIMS: Impella is a microaxial rotary pump that is placed across the aortic valve to expel aspirated blood from the left ventricle into the ascending aorta; it can be used in cardiogenic shock. While previous studies have evaluated the efficacy and safety of the Impella device, more clinically relevant data are necessary, especially with regard to outcomes. METHODS AND RESULTS: We screened our database of Impella patients in our heart center and found 68 consecutive patients who underwent Impella implantation due to acute coronary syndrome (ACS) complicated by cardiogenic shock...

Temporary mechanical circulatory support (MCS) is a common supportive therapy in cardiogenic shock and high-risk coronary intervention. The proliferation of new percutaneous MCS devices allows support to be instituted rapidly without surgical cutdown. The recent literature exploring the indications, benefits, and risks of each is reviewed. Areas discussed: Current applications of percutaneous MCS devices, including intra-aortic balloon pumps (IAPB), Impella, TandemHeart, and VA ECMO are discussed. Studies investigating each were identified through a combination of online database queries and direct extraction of single studies cited in previously-identified papers...

OBJECTIVES: The use of intracardiac assist devices is expanding, and correct position of these devices is required for optimal functioning. The aortic valve is an important landmark for positioning of those devices. It would be of great value if the device position could be easily monitored on plain supine chest radiograph in the ICU. We introduce a ratio-based tool for determination of the aortic valve location on plain supine chest radiograph images, which can be used to evaluate intracardiac device position...

Traditionally, brachial and common femoral arteries have served as access sites of choice, with many operators recently converting to radial artery access for coronary angiography and percutaneous intervention due to literature suggesting reduced bleeding risk, better patient outcomes, and lower hospital-associated costs. However, radial access has limitations when percutaneous procedures requiring larger sheath sizes are performed. Six Fr sheaths are considered the limit for safe use with the radial artery given that the typical luminal diameter of the vessel is approximately 2 mm, while peripheral artery disease (PAD) may often limit use of the common femoral artery, particularly in patients with multiple co-morbid risk factors...

BACKGROUND: In cardiogenic shock (CS) the Impella CP® device provides a fast available left ventricular circulatory support of up to 4.0L/min. However, the use of the Impella CP® device was not systematically analysed yet. METHODS: We performed a retrospective analysis of 28 consecutive patients suffering from severe therapy refractory CS treated with Impella CP®. Mortality was estimated using the SAPS II-Score. Primary outcome was 30-day survival. We compared the different aetiologies of CS and the effect of additional extracorporeal life support (ECLS)...

High-risk percutaneous coronary intervention (PCI) is often offered to patients with extensive coronary artery disease, decreased left ventricular function, and co-morbid conditions that increase surgical risk. In these settings, percutaneous left ventricular assist devices (PVADs) can be used for hemodynamic support. To assess the effects of PVAD use on mortality, myocardial infarction, and complication rates in patients undergoing high-risk PCI, we systematically searched the electronic databases, MEDLINE, PUBMED, EMBASE, and Cochrane for prospective controlled trials and cohort studies of patients that received hemodynamic support with PVADs for high-risk PCI...
