EU Launch of Sorin’s REPLY CRT-P, World’s Smallest Cardiac Resynchronization Pacemaker

Italian cardiovascular device company, Sorin Group is launching its new REPLY CRT-P, cardiac resynchronization therapy pacemaker, claiming it to be the smallest device of its type in the world.


The REPLY CRT-P with its 11.3 cc in volume is indeed diminutive, and features proprietary algorithms aimed at better supporting heart failure management and ultimately improving patient outcome, says the company

Data from HF population studies suggest that both obstructive sleep apnea as well as central sleep apnea may be present in 30% to 50% of HF patients. If left untreated, sleep apnea increases the risk of death and HF hospitalization. The REPLY CRT-P device’s Sleep Apnea Monitoring (SAM) algorithm detects severe sleep apnea using a highly reliable sensor that measures ventilation and can effectively screen these patients for severe sleep apnea so that they can be treated. In addition, it can be used to monitor the long term progression of the disease.

Reply CRT-P also features Sorin’s dual sensor technology which is designed to enable a physiologic adaptation of the heart rate during exercise. In contrast to single sensors, the dual sensor responds to the metabolic demand of the body via the minute ventilation sensor and avoids any inappropriate reaction from the accelerometer thanks to its cross-checking technology. As a result, Reply CRT-P ensures optimal conditions for exercise training which is recommended for HF patients as it allows for maximal benefit of CRT.

Physician comments

The first REPLY CRT-P was implanted by Dr. Brian Gordon at Papworth Hospital in Cambridge, UK. The patient was a 72-year-old female with dilated cardiomyopathy. “The small size of the device is very impressive” said Dr. Gordon. “Size is an extremely important consideration for many patients alongside battery longevity and Reply CRT-P is setting the standard for the former without compromising the latter.”

Company comments

“Sorin Group is dedicated to developing solutions for heart failure that enable optimal management of comorbidities such as sleep apnea.” said Stefano Di Lullo, President, Cardiac Rhythm Management business unit. “REPLY CRT-P is another example of this, providing state-of-the-art cardiac resynchronization therapy for HF patients while at the same time enabling the intuitive screening and monitoring of sleep apnea.”
