The PulseCath iVAC 3L™ left ventricular assist device is an option to treat transitory left heart failure or dysfunction post-cardiac surgery. Assisted blood flow should reach up to 3 l/min. In the present in vitro model exact pump flow, depending on various frequencies and afterload was examined. Optimal flow was achieved with inflation/deflation frequencies of about 70-80/min. The maximal flow rate was achieved at about 2.5 l/min with a minimal afterload of 22 mmHg. Handling of the device was easy due to the connection to a standard intra-aortic balloon pump console. With increasing afterload (up to a simulated mean systemic pressure of 66 mmHg) flow rate and cardiac support are in some extent limited.

Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is increasingly used in bi-ventricular failure with cardiogenic shock to maintain systemic perfusion. Nonetheless, it tends to increase left ventricular (LV) afterload and myocardial oxygen demand. In order to mitigate these negative effects on the myocardium, an Impella CP® (3.

Aims: Our aim was to test the feasibility and safety of the transfemoral PulseCath iVAC 2L (PulseCath, Amsterdam, The Netherlands).
Methods And Results: Circulatory support devices are helpful adjunctive tools to perform high-risk percutaneous coronary interventions (PCI). The PulseCath iVAC 2L is a novel pulsatile circulatory support system capable of generating output of up to 2 L/min.

Aims: This technical report describes the essentials and practical implantation technique of the completely percutaneous PulseCath iVAC 2L left ventricular assist device.
Methods And Results: Percutaneously inserted mechanical left ventricular assist devices are used for circulatory support during cardiogenic shock or high-risk percutaneous coronary interventions. The PulseCath concept is a novel pulsatile design that consists of an extracorporeal membrane pump connected to a large-bore catheter which is inserted across the aortic valve retrogradely into the left ventricle.

Extracorporeal membrane oxygenation (ECMO) has become a widely accepted short-term mechanical circulatory support device in patients with refractory cardiogenic shock. A major drawback of the peripheral venoarterial extracorporeal membrane oxygenation is that in patients with profoundly reduced left ventricular contractility associated with high left-heart filling pressure, there is always concern for venting the failing ventricle. We describe a minimally invasive technique for decompressing the left ventricle in this setting using a novel pulsatile paracorporeal assist device, the iVAC 3L (PulseCath, Groningen, The Netherlands).
