What is a Protek duo cannula?
Protek Duo is a dual lumen cannula devise inserted percutaneously via internal jugular (IJ) venous access. Proximal inflow lumen is positioned in the right atrium and distal outflow lumen is positioned in the main pulmonary artery.
Is Protek duo ECMO?
With the Protek Duo device, deoxygenated blood is drained through the superior vena cava to the ECMO circuit and then pumped into the main pulmonary artery.
What is a Protek?
The Protek Duo (TPD) is a temporary RVAD placed via the right internal jugular vein, capable of providing up to 4.5 L of flow. We report a two-center experience using the TPD in 17 patients with right ventricular (RV) failure, 12 of whom were post-left ventricular assist device (LVAD) implantation.
What is the difference between VV ECMO and VA ECMO?
ECMO, Extra Corporeal Membrane Oxygenation. VA ECMO provides both respiratory and hemodynamic support; the ECMO circuit here is connected in parallel to the heart and lungs, while in VV ECMO the circuit is connected in series to the heart and lungs. During VA ECMO, blood will bypass both the heart and the lungs.
What is VAV ECMO?
Veno-arterio-venous ECMO (VAV). VAV-ECMO drains venous blood (blue) from the right atrium and returns balanced volumes blood after reoxygenation and decarboxylation (red) to the iliac artery toward the aorta and to the right atrium toward the pulmonary circulation.
What is a TandemHeart?
The TandemHeart is a left atrial-to-femoral artery bypass system comprising a transseptal cannula, arterial cannulae, and a centrifugal blood pump. The pump can deliver flow rates up to 4.0 L/min at a maximum speed of 7500 rpm.
How does Protek duo work?
The PROTEK Duo works via an internal jugular vein and can be placed so that the blood moves from the right atrium into the pulmonary artery, improving oxygenation and relieving the right side of the heart. The device has been already been available and in use in the United States since last year.
What is North South Syndrome?
Harlequin syndrome, also known as “North–South Syndrome” or “Dual Circulation,” occurs when there is an area of watershed within the aorta where the ECMO oxygenated blood from the femoral artery meets the low oxygenated blood from the impaired lungs, during peripheral VA-ECMO.
Where do you Cannulate for VV ECMO?
V-V ECMO. V-V or veno-venous ECMO, supports lung function primarily. The surgeon will place the cannulae in a large vein only, usually in the neck. Based on the patient’s age and condition, the surgeon may choose to place one special cannula in a single vein or place two cannulae in two different veins.
What are the two types of ECMO?
There are two types of ECMO, venovenous (VV) and venoarterial (VA) (figure 1 and figure 2 and figure 3). VV ECMO is used in patients with respiratory failure, while VA ECMO is used in patients with cardiac failure.
Is TandemHeart an LVAD?
Is TandemHeart an ECMO?
Our experience suggests that the TandemHeart catheter system can offer innovative and superior options for ECMO delivery to different populations of patients who experience cardiopulmonary failure.
What is a protekduo® veno-venous cannula?
The ProtekDuo® veno-venous (V-V) dual lumen cannula permits a form of extracorporeal mechanical circulatory support using an oxygenator and, when combined with a TandemHeart® pump, can deliver close to 4 liters/minute of flow allowing the right side of the heart to rest while right-to-left flow is augmented.
What is Protek duo emergency cannula?
PROTEK Duo Emergency Cannula for Veno-Venous Extracorporeal Life Support. The device is designed to overcome limitations of mechanical ventilation, bypassing the lungs and delivering oxygen straight into the blood using an oxygenator. It can be paired with the TandemHeart pump, which offers up to a month of circulatory support.
How does the Protek duo work?
The PROTEK Duo works via an internal jugular vein and can be placed so that the blood moves from the right atrium into the pulmonary artery, improving oxygenation and relieving the right side of the heart.
