Article Discusses Vectorious Medical Technologies' Digital Wireless Sensory Implant for Left Atrial Pressure Measurement
July 28, 2017—Vectorious Medical Technologies, an Israeli company developing a digital wireless sensory implant for measuring left atrial pressure (LAP), announced the publication of an article by William T. Abraham, MD, and Leor Perl, MD, reviewing current and next-generation implantable hemodynamic monitors in the Journal of the American College of Cardiology (JACC;2017;70;389–398).
The article discusses how new approaches focused on the direct measurement of LAP seek to expand the use of pressure-guided congestive heart failure (CHF) management. LAP is analog to the currently available CardioMEMS technology that measures pulmonary artery pressure (PAP).
According to the company, the Vectorious V-LAP measures the heart’s LAP. It provides a high-resolution waveform morphology of LAP, allowing for the detection of additional cardiac comorbidities such as atrial fibrillation and mitral valve regurgitation.
In the company's announcement, Drs. Abraham and Perl commented, “Intracardiac and PAP-guided management has become a focus of hospitalization reduction in CHF.” LAP, rather than PAP, is a direct reflection of left ventricular filling pressure—which is the primary pressure target for CHF management; therefore, its direct measurement may provide more clinical information than PAP.
Drs. Abraham and Perl stated in JACC that CHF outcomes with CardioMEMS PAP technology have been encouraging. They write that, additional, more technologically advanced, implantable hemodynamic monitoring systems are in development, and newer approaches to the use of these data (such as a physician-directed, patient self-management approach) may yet again revolutionize the management of patients with HF.
Dr. Abraham, who is from The Ohio State University in Columbus, Ohio, serves on the company's scientific advisory board. Dr. Perl, who is from Rabin Medical Center in Petah Tikva, Israel and Stanford University Medical Center is Stanford, California, is Medical Director of Vectorious.
