The procedure was finished in 44 minutes, required local anesthesia and recovery time was no longer than 24 hours. The MICRA pacemaker was developed by Medtronic, is only 2,5cm (roughly 1in) in size, weights 2 grams, does not require electrodes and this is the first time it has been installed in a heart.

The first time the world’s smallest pacemaker was implanted in Latin America it took place at Hospital San José, in Santiago. The procedure was carried out by Dr. Marrero, who trained for it at Medtronic training center in the United States, where the device was developed.

As this device is wireless, it is less prone to exteriorization or infection, which aids in making the recovery process shorter and safer. Specially as chances of requiring another intervention are significantly lower. This means that the procedure becomes less complex, thus reducing costs and duration for both patients and hospitals.

MICRA is powered by a battery that lasts approximately 10 years. There are currently 10 thousand people from 40 countries reaping benefits from the world’s smallest pacemaker, and Chile now joins them as Latin America’s first country to use this technology in order to help people with heart failure.

After surgery, José Miguel Puccio, Director at Hospital San José, stated that “As a hospital we are proud to carry out a procedure such as this, which makes us pioneers in Latin America, additionally, as we are a public institution, this showcases the skills of both professionals and equipment that we have in our country”.
