Abstract
BACKGROUND AND OBJECTIVE
A first publication of our group demonstrated that implantation of a loop recorder in 30 patients experiencing an unexplained syncope (Medtronic Reveal DX or XT) definitively determined that an arrhythmia was the cause of symptoms in 10 patients (32%). However, we lack the results of a survey evaluating the results of long term follow-up after a loop recorder implantation and the results in case of wider indications of implantation of loop recorders.
METHODS AND RESULTS
A device (Medtronic Reveal DX or XT) was implanted in 97 patients between january 2009 and june 2014. During a mean follow-up of 21±19 months, loop recording determined that an arrhythmia was the cause of symptoms in 34 patients (35%). For the management of these arrhythmias, treatments received by patients were a pacemaker implantation in 18 patients (53%), an implantable cardioverter-defibrillator in four patients (12%) and a supraventricular tachycardia ablation (cryo or radiofrequency ablation) in three patients (9%). For nine patients (26%), the arrhythmic events were asymptomatic and didn't justify a specific treatment. The final positive rate of loop monitoring implantation was of 25/97 (26%). The study demonstrated that the positivity of the follow-up was demonstrated after two years of follow-up in 26% of the cases.
CONCLUSION
Long-term follow-up of 97 patients implanted by a loop monitor leaded to an interventional rythmology procedure in 26% of the cases. In 26% of patients, loop-monitoring follow-up was positive after a duration of more than two years.
