In recent years, implantable mechanical circulatory devices have become an increasingly popular option for patients with progressive, chronic heart failure. Ventricular assist devices are commonly indicated for use for bridge to transplant, bridge to candidacy, bridge to recovery or destination therapy. Thankfully, due to improved flow measurement within these devices, patients are having higher success rates and improved quality of life.

Right heart failure continues to threaten many patients who undergo left ventricular assist device implantation. The hemodynamics within the heart are constantly changing creating a dynamic atmosphere. Confidence in LVAD application and efficiency is mandatory in preventing and diagnosing changes in right ventricular function.

 

Percutaneous VADs (pVADs)

In patients who have developed heart failure as a result of heart surgery or a heart attack, implantation of a percutaneous ventricular-assist devices (pVADs) is one strategy to achieve this cardiogenic shock therapy. Cardiogenic shock is a hemodynamic problem characterized by impaired cardiac output leading to reduced systemic perfusion, increased residual volumes in both ventricles and increased cardiac filling pressures. A primary treatment for cardiogenic shock is mechanical circulatory support. This mechanical support remains short-term providing patients with time to regain enough cardiac function to be only medically managed.

Transonic is proud to be an integral part of percutaneous ventricular assist device creation. Throughout different stages of development mock flow models depend on Transonic tubing measurements to test the devices, proving Transonic’s level of experience and expertise.

 

XL-Flowsensors

Transonic is committed to improving the outcomes of patients reliant on mechanical circulatory support devices. Our H-XL-Series of Clamp-on Tubing Flowsensors provides clinicians with true blood flow within the circuit. By comparing actual delivered blood flow to the set flow on the pump, clinicians will be alerted to changes or interruptions of the patients delivered blood flow. Early detection of changes provides the opportunity to make corrections or alterations on the spot. An external clamp-on Flowsensor clips onto the tubing to continuously monitor actual flow delivery to the patient. Measurements are non-invasive, continuous and bi-directional.

 

VAD Implantation

Surgery for implantation of a mechanical circulatory device are precarious and require intense precision from everyone on the surgical team. Transonic’s Perivascular COnfidence Flowprobe can be used intra-op to provide additional security and assurance. The COnfidence Flowprobe can measure direct blood flow in the aorta or pulmonary artery during VAD implantation to maintain an appropriate Qp:Qs ratio for each and every patient.
