In Spain, more than 34,000 pacemakers are implanted annually. In nine out of ten occasions it is customary for tip of the right ventricle be the place of implantation of it. However, specialists in cardiology gathered in the framework of the 27th spring meeting of the Cardiac Stimulation Section, held in Cartagena, have debated whether or not to modify the implantation site of a pacemaker, since it seems proven that a quarter of the Intervened patients see their ventricular function deteriorated, developing heart failure or other arrhythmia in the three years following implantation of the device.

In order to find alternatives, three multicenter studies are being carried out: RAPS, PROTECT PACE and Optimize RV, which aim to demonstrate the benefits of implementing these devices near his area or in the outflow tract of the right ventricle, thus optimizing the ventricular synchrony, conserving the ejection fraction (percentage that measures the decrease of the volume of the left ventricle in contraction with respect to when it is in relaxation) and improving the evolution of the patient.

For Dr. Jesus Rodriguez, member of the SEC and cardiologist at the Coronary Unit of the Hospital Universitario 12 de Octubre in Madrid, "we are at a critical moment in which the cable is still being placed on the tip of the right ventricle in clinical practice, although You have to take a leap and change this site. The results of these studies and the work of scientific societies will promote the attitude of this change soon, "he says.

As he explained, "the new implantation sites are equally easy and safe and have the same electrical performance and even present fewer complications, we will have to go through a learning process to familiarize the specialists with the new implantation site of the pacemaker" , has clarified.
