The company has designed the MultiPoint Pacing technology with the SyncAV CRT software algorithm for the treatment of heart failure patients who are not responsive to other pacing options.

SyncAV technology is said to automatically adjust pacing based on real-time changes in a patient’s cardiac condition.

The updated labeling allows Quadra Assura MP CRT-D to provide patients with unrestricted access to MRI diagnostic testing.

For heart failure patients, CRT technology resynchronizes the lower chambers (ventricles) of the heart by transmitting uniquely programmed electrical impulses to stimulate each ventricle to beat in sync.

The MultiPoint Pacing technology, which is also featured on the Quadra Allure MP CRT-P, will deliver independent electrical pulses to multiple locations on the Quartet lead to make the heart’s lower chambers pump in a coordinated way to reflect the natural contractions of a healthy heart.

John Radcliffe Hospital’s Oxford Heart Centre consultant cardiologist and electrophysiologist Dr Timothy Betts said: "The SyncAV CRT algorithm dynamically individualizes programming to work towards providing patients with the right settings at the right time helping offer the best possible outcome for even our most complex patients."

In May, St. Jude Medical received CE mark approval for its PressureWire X Guidewire fractional flow reserve (FFR) measurement system.

The system was developed to identify the severity of narrowings in the coronary arteries of patients with coronary artery disease (CAD).
