An additional method to ensure proper depth is to interrogate the aortic root with color Doppler from the parasternal long-axis view.
It is important to recognize that adjustments from the vascular access site are not necessarily transmitted to the cannula in a 1:1 fashion due to slack and/or torque that may exist or be introduced into the catheter. We found performing such changes at a consistent time to be very helpful. Once the imager has a nonforeshortened image of the catheter in the parasternal long-axis view, the Impella motor speed should be temporarily set to power level P2, which reduced the risk of damaging the submitral apparatus during the catheter manipulation. The Rise of Endovascular Mechanical Circulatory Support Use for Cardiogenic Shock and High Risk Coronary Intervention: Considerations and Challenges. Sheaths were placed in the right femoral vein, the right femoral artery, and the left femoral artery. Expert Rev Med Devices. He had severe mitral regurgitation. In our facility, this role is filled by the interventional cardiology clinical nurse specialist. Device-related complications occur more frequently with a longer duration of support. The trials primary end point of hemodynamic improvement was defined as improved cardiac index at 30 minutes after implantation. The use of continuous cardiac output monitoring may be useful for patients with cardiogenic shock. The smaller diameter Impella 2.5 and CP are typically inserted percutaneously under fluoroscopic guidance in the cardiac catheterization laboratory; however, transesophageal echocardiography (TEE) guided placement is also possible.1 The larger diameter Impella 5.0 and 5.5 are typically inserted by surgical cutdown via a prosthetic graft sewn onto the subclavian artery and are positioned under fluoroscopy or by TEE. If TTE imaging is difficult, fluoroscopy or TEE can also be used. An axial pump is one that is made up of impellar blades, or rotors, that spin around a central shaft; the spinning of these blades is what moves blood through the device.13 The distal tip of pigtail curve is 6F in size (Figure 4). The Impella 2.5 instructions for use recommend a 40-minute manual hold to achieve hemostasis at the arterial access site. The motor current signal will be flattened. The alarm will read pump position unknown due to low pulsatility. The Impella console is not able to determine the pump position because the patients systolic and diastolic pressures are not very different. Regular repositioning of patients and assessment of their skin are necessary to prevent skin breakdown. On arrival, his blood pressure was 105/66 mm Hg with a heart rate of 64/min. 1. IABP therapy has been in use since the late 1960s and has been widely used in clinical practice since that time. The Impella RP is a right ventricular (RV) support system that is percutaneously positioned in the pulmonary artery via the femoral vein under fluoroscopy. 0000004641 00000 n
23. Cardiogenic Shock | Hospital Handbook The Impella catheter must be adequately positioned to provide optimal hemodynamic support while minimizing the risk of complications, including hemolysis, interference with the mitral apparatus, suction events, or provocation of ventricular arrhythmias. Abiomed has sponsored several of these trials, including PROTECT I, PROTECT II, RECOVER I, RECOVER II, and ISAR-SHOCK. In Europe, the Impella 2.5 is approved for use up to 5 days. A 74-year-old man was transferred to our facility after sustaining a nonST-segment elevation myocardial infarction. The VAD coordinators also provide valuable assistance. Pahuja M, Hernandez-Montfort J, Whitehead EH, Kawabori M, Kapur NK. Heparin 9000 units was administered intravenously for anticoagulation, and the Impella 2.5 was advanced into position in the left femoral artery. The second lumen of the Impella 2.5 is flushed with heparinized saline (500 mL normal saline with 1000 units heparin) by using regular (not infusion pump) intravenous tubing. You may be trying to access this site from a secured browser on the server. Additional torque can be achieved by rotating the red Impella plug (Figure 5) at the proximal end of the catheter in the desired direction. 0000000636 00000 n
Jo Kajewski, Advanced Impella Trainer, gives an in-depth look at managing Impella positioning using imaging. The coronary guidewire was advanced through the LIMA graft to the distal LAD. Brenda McCulloch is a member of the Abiomed Administrative Advisory Board. The use of inotropic agents and vasopressors was similar in both groups of patients. In cases where transesophageal ultrasound is used for catheter placement or repositioning, the midesophageal long-axis view (120) is the most reliable and accurate to assess catheter depth. We have extensive experience with the IABP and with surgically placed VADs, including the Abiomed AB5000, Thoratec CentriMag, XVE, and HeartMate II. The console uses this pressure measurement to calculate the catheters position. This site needs JavaScript to work properly.

The Impella mechanical circulatory support (MCS) system is a catheter-based continuous flow cardiac assist device that is widely used in the treatment of cardiogenic shock in medical and surgical cardiac intensive care units. When the Quick Set-Up is used, the 10% to 20% dextrose solution used to purge the motor is not heparinized. A 71-year-old man was referred to our facility for saphenous vein bypass graft (SVG), a high-risk PCI. The patient was rapidly weaned from the Impella, which was removed in the catheterization laboratory. Arterial repair is done at that time, and the incision is covered with a sterile dressing. The following 3 case studies demonstrate the successful use of Impella 2.5 support during high-risk PCIs at our facility. If the patient tolerates the PCI procedure and hemodynamic instability does not develop, the Impella 2.5 may be removed at the end of the case while the patient is still in the catheterization laboratory.
Frontiers | Ventricular Unloading Using the ImpellaTM Device in The Impella 2.5 catheter has 2 lumens. A culprit oriented approach should be used when troubleshooting the Impella supported patient with signs of persistent circulatory failure. As the performance level increases, the flow rate and number of revolutions per minute increase.
Impella Flashcards | Quizlet Our training for our cardiac intensive care unit (CICU) nurses consisted of a series of three 1-hour sessions, encompassing a review of pertinent physiology and hemodynamics, Impella console management and troubleshooting, and tubing changes with hands-on practice and documentation practice. Read below to find out how long a swollen uvula lasts and how to get treatment. The Impella catheter has become a common MCS device used in medical and surgical cardiac intensive care units, and as such intensivists must have a core competency with its management. In our facility, we have a trained CICU nurse managing the Impella while the patient is in the cardiovascular operating room. Impella heart pumps have been tested under simulated conditions of inflow and outflow obstruction. The Impella RP has been authorized only for the duration of the declaration that circumstancesexist justifying the authorization of the emergency use of medical devices under section 564(b)(1) of.
Perioperative Management of Patients Receiving Short-term Mechanical All cases are also followed by the cardiac surgeon who oversees our VAD program and a critical care intensivist.

Correspondence: Alexander Papolos, MD, Departments of Cardiology and Critical Care, MedStar Washington Hospital Center, 110 Irving St., NW, Rm A127, Washington, DC, 20010. Impella has been proven to be safe and may be superior to other mechanical support devices in CS. The left main lesion was crossed, and one stent was deployed at the lesion. However, in severe cases of RV failure or when pre-capillary pulmonary hypertension is a contributing factor, right-sided MCS and pulmonary vasodilator titration may be required, respectively. Indications 1. A multidisciplinary approach to establishing a program for the Impella is useful in ensuring competency and good outcomes for patients. doi: https://doi.org/10.4037/ccn2011293. Please enable it to take advantage of the complete set of features! 4, 5 Right ventricular failure occurs in 25% of patients after left ventricular assist device insertion, thus the advent of Impella RP. 0000007230 00000 n
The morphology of the placement signal resembles that of an arterial waveform, which can be counterintuitive as the peak of the waveform occurs in diastole when the gradient between the LV and aorta is greatest, whereas the nadir occurs during systole when it is least. government site. If the Impella remains in place for continued support after the PCI, the tubing system is changed to 2 separate systems. Information about the alarm can be seen on the console screen. In our facility, we often use transthoracic echocardiography to aid in the assessment of our patients. ). Inotropic agents, such as dobutamine and milrinone, and vasopressors, such as dopamine and norepinephrine, may still be needed after the Impella 2.5 is placed to maintain a cardiac index of at least 2 and systolic blood pressure at 90 mm Hg or higher. Areas covered: The second indication is to prevent clot formation on the catheter itself and potential embolization into the patient. The heparinized saline is placed in a pressure bag that is inflated to 300 mm Hg. If the catheter pigtail is hooked on the mitral apparatus and/or papillary muscle, it may be necessary to first advance the catheter deeper into the ventricle and then rotate the catheter to disengage it from the valvular structures. We have gained much knowledge since implementing our Impella program in April 2008. Federal government websites often end in .gov or .mil. Ongoing practice is essential to develop and maintain competency. Our facility has a high-volume interventional cardiology program as well as a busy adult and pediatric cardiovascular surgery service. In our facility, physicians who can place this device are those who have interventional cardiology and/or cardiac surgery privileges. 0000001527 00000 n
: Increased plasma-free hemoglobin levels identify hemolysis in patients with, 5. The Impella is placed percutaneously, most commonly via the femoral or axillary artery, into the aorta, and across the aortic valve.
The physician can evaluate left ventricular size and function and can quickly assess how well the patient tolerates decreases in the performance level. The entire LV placement signal waveform shifts downward. Suction alarms can occur if the performance level is too high for the patient; for example, in a patient who is hypovolemic or if the device is emptying the ventricle. Nursing care is directed toward support of critically ill patients, including frequent hemodynamic assessment, titration of vasoactive medications as indicated, Impella console troubleshooting, and monitoring for potential complications. Optimal hemodynamic effect from the IABP is dependent on several factors, including the balloons position in the aorta, the blood displacement volume, the balloon diameter in relation to aortic diameter, the timing of balloon inflation in diastole and deflation in systole, and the patients own blood pressure and vascular resistance.3,4, The Impella 2.5 (Figure 1) aspirates up to 2.5 L/min of blood from the left ventricle and displaces it into the ascending aorta, rapidly unloading the left ventricle and increasing forward flow. The tip of the catheter has a flexible pigtail, intended to prevent mechanical injury of the ventricle (absent on the larger LD and 5.5 models). The Impella device can be withdrawn, leaving the arterial sheath in place. Please try again soon. Our use of the Impella 2.5 was our first experience with percutaneously placed partial circulatory support devices. She was treated with fibrinolytic therapy but continued to have chest pain. As with all current forms of MCS, device-related complications remain a major concern, many of which can be mitigated by adhering to a few fundamental concepts in device management. eCollection 2021. P2 is the lowest performance level that can be used while the distal end of the Impella 2.5 is in the left ventricle. When activated, the console is silent. The Impella 2.5 is able to unload the left ventricle rapidly and effectively and increase cardiac output more than an intra-aortic balloon catheter can. to maintaining your privacy and will not share your personal information without
There are currently five Impella catheters that provide left ventricular (LV) support (Figure 1).
Toddler On Board Car Sign, Suction Cup Baby On Board Sign, Child - eBay The Impella (Abiomed Inc.) is an axial flow pump on a pigtail catheter that is placed across the aortic valve to unload the left ventricle by delivering non-pulsatile blood flow to the ascending aorta. The placement signal will show depressed cardiac function, evidenced by a damped appearing waveform. Impella use in real-world cardiogenic shock patients: Sobering outcomes. Subramaniam AV, Barsness GW, Vallabhajosyula S, Vallabhajosyula S: Complications of temporary percutaneous. This arrangement allowed ample time for setting up the console and infusion pump before the Impella was placed. The pharmacy prepares the heparinized 20% glucose purge solution and sends it to the unit before our standard change time of 3 pm daily. Patel SM, Lipinski J, Al-Kindi SG, et al. During this time, transient no-reflow developed. may email you for journal alerts and information, but is committed
The aortic valve symbols will not be seen on the placement monitoring diagram. Learn more about how the FDA-approved Impella, the world's smallest heart pump, is safe, effective and supports your heart during a procedure. Cardiogenic shock was defined as a (1) systolic blood pressure 90 mm Hg or need for inotropes or vasopressors to maintain systolic blood pressures 90 mm Hg, (2) signs of peripheral hypoperfusion, and (3) cardiac index <2.2 L/min/m 2 and pulmonary capillary wedge pressure 15 mm Hg. SmartAssist technology on the Impella CP or Impella 5.5 devices can help with this as well.
FACT SHEET FOR HEALTHCARE PROVIDERS - Food and Drug Administration To monitor the severity of hemolysis we recommend daily monitoring of serum creatinine, and plasma-free hemoglobin (PFH) or lactate dehydrogenase (LDH). An enlarged uvula is often caused by infection, an allergic reaction, or irritation from chemicals or medical procedures.

Impella Flashcards | Quizlet With the physician at the bedside, transthoracic echocardiography is performed and the pumps performance level is decreased. The Impella 2.5 is a percutaneously placed partial circulatory assist device that is increasingly being used in high-risk coronary interventional procedures to provide hemodynamic support. We recommend that repositioning of the Impella catheter be performed by two people, one to obtain real-time ultrasound images and one to manipulate the catheter. 2021 Mar 26;100(12):e25159. Our practice is to integrate clinical factors, such as mean arterial pressure, heart rate, and urine output with invasive hemodynamics, and lab dataspecifically, serum lactate and pulmonary arterial oxygen saturation every 6 hours. The Impella is a really cool piece of equipment, a percutaneous ventricular assist device (primarily used for the LV, but can be used for the RV). The Impella should not be used in patients with a heavily calcified aortic valve. Curr Cardiol Rep. 2018 Jan 19;20(1):2. doi: 10.1007/s11886-018-0946-2. As the Impella RP is not widely used, this review will focus only on the left-sided catheters; however, many of the concepts discussed are transitive. Context in source publication. The use of pulmonary artery catheters with ongoing RP has not been thoroughly evaluated, and evaluation should also rely on clinical evaluation, oxygen demand, chest X-ray, etc. Two patients had transient hemolysis that was not clinically significant. To understand the hemodynamics of a patient in cardiogenic shock receiving Impella support, a pulmonary arterial catheter is recommended.5 The overall weaning strategy is to achieve adequate organ perfusion at the lowest device power setting to minimize device-related complications and to determine candidacy for device removal. Free shipping for many products! Several parameters require regular monitoring for the duration of therapy. Patients on Impella 2.5 support who may require interrogation of a permanent pacemaker or implantable cardioverter defibrillator present an interesting situation. Notably, low native heart pulsatility may similarly trigger either the Impella Position Wrong or the Impella Position Unknown alarm, as the software cannot interpret the dampened amplitude of the placement signal and motor current (Figure 3E). The structural design of each of these LV support catheters is grossly similar (Figure 2). It is used for high-risk percutaneous coronary intervention and CS. Transthoracic echocardiography should be used to visualize the device. Percutaneous mechanical support devices are placed in a minimally invasive manner and provide life-saving assistance. Accessibility Keyword Highlighting
She was taken to the catheterization laboratory, where she was found to have a significant obstruction of the left main coronary artery complicated by plaque rupture. Optimal imaging often requires off-axis parasternal long-axis views obtained by fanning and rotating the probe until the entire length of the cannula and the aortic annulus are seen. There is a pressure sensor built into the aortic end of the cannula that is used to produce a placement signal waveform tracing (Figure 3A). On imaging, if the LV appears overly decompressed due to a significant interventricular septal shift, then reducing the Impella speed, escalating inotropy to support the RV, and increasing volume removal is commonly the best course of action.

The catheter is not tethered to any internal structure and is prone to migration which occurs more frequently when the catheter is placed percutaneously. The cannula portion of the catheter is built with a 30 bend (except for the Impella LD, which has a straight design). The site is secure. Patients in cardiogenic shock supported by venoarterial extracorporeal membrane oxygenation (VA-ECMO) often require an LV unloading strategy to prevent the development of pulmonary edema, thrombus formation in the LV, and reduce LV wall stress.6 The concurrent use of VA-ECMO with the Impella catheter as an unloading strategy (ECPELLA) has become a popular MCS configuration associated with improved cardiogenic shock outcomes over VA-ECMO alone.7 The management of the Impella catheter while in the ECPELLA configuration is no different than described elsewhere in this review.
