March 29, 2016 — St. Jude Medical Inc. announced CE Mark approval and launch of three new Quartet left ventricular (LV) leads, offering additional electrode spacing options and one new lead shape. The additional spacing combinations are aimed to more effectively target the individual cardiac anatomies of patients who need support from cardiac resynchronization therapy pacemakers (CRT-P) and defibrillators (CRT-D).
“Heart and blood vessel anatomy vary from patient to patient, so having multiple sizes and spacing options with the Quartet quadripolar lead helps me to treat all of my patients in need of cardiac resynchronization therapy. We are now able to place the quadripolar lead in the best possible location for that patient, capturing more cardiac tissue to give heart failure patients the best opportunity to respond,” said Sami Pakarinen, M.D., a cardiologist from Helsinki University Central Hospital in Finland.
Studies have shown that CRT can improve the quality of life for many patients with heart failure. CRT resynchronizes the beating of the heart's lower chambers (ventricles), which often beat out of sync in heart failure patients. The addition of MultiPoint Pacing technology enables physicians to program a single Quartet LV lead to pace multiple sites on the left side of the heart, giving the clinician more choices to improve patient response to therapy and reducing the likelihood of costly and invasive lead revision through a second intervention procedure.
The new leads are designed based on the company’s proven quadripolar LV lead technology and include additional spacing options on two new S-shape and one new double-bend lead designs.
Some of the newly approved products are also magnetic resonance (MR) – conditional, including the Quadra Assura CRT-D and Quadra Assura MP CRT-D with MultiPoint Pacing. Additionally, physicians will be able to quickly customize therapy using the Auto VectSelect Quartet Test, which is designed to automatically guide programming of the most appropriate therapy options available and streamline workflow.
