Recently, Quadripolar technology was launched in India, and it was designed to help overcome many challenges of left ventricular (LV) placement. Using the new lead technology, which has four pacing electrodes and ten pacing vectors, it is possible to re-position the LV lead electronically, which helps in avoiding another surgery and any resulting complications.
Quadripolar pacing has been an important topic over the past few years, with a significant amount of research taking place in Europe and U.S. on this issue. We are planning to participate in clinical studies regarding Quadripolar pacing technology at BM Birla Heart Research Centre in the near-term.
The main difference is that for the first time within the industry there are four electrodes, which enables up to ten pacing configurations. According to the latest research, the increased options for configurations help to reduce complications of high threshold and phrenic nerve stimulation. Quadripolar technology also has a unique design that enables basal pacing which results in about 50 percent fewer heart failure hospitalisations or deaths when compared with apical pacing. Moreover with its proven S-curve design chances of lead dislodgement is lowest.
In the future, I look forward to have combination of features in the Quadripolar device including QHR Battery Technology and CorVue. The QHR battery packs more energy and increases the longevity of the CRT device and the CorVue feature helps monitor the fluid congestion in lungs, which can warn the patient and physician well in advanced of clinical episode of heart failure. This allows us to alter medication and change therapy to prevent an episode of heart failure and hospitalisation.
