Indications and results of definitive cardiac stimulation at the National Heart Center of Nouakchott (Mauritania) : About 60 cases

Abstract

Introduction: The cardiac stimulation is the only effective therapeutic solution for major conductive disorders. The principle of this technique is to put one or more endocavitary stimulation probes, linked to a pacemaker implanted in a prepectoral lodge, to control a chronotropic insuf iciency responsible for a decrease in cardiac output, putting the patient's vital prognosis at risk. The practice of this technique in Mauritania is relatively recent. The objective of the study : 1. Describe epidemio‑clinical, paraclinical aspects and indications of our patients. 2. Evaluate the results of permanent cardiac pacing in our patients. Materials and Methods : We conducted a retrospective study, over a 2 years period of (January 1, 2014 to December 31, 2015). Implantation of the pacemaker was performed under local anesthesia at the cardiac catheterization room. Results : The mean age of our patients was 67 years with male predominance (62%), the prevalence of major conduction disorders was 1.3%. The degeneration conduction tissue was the main etiology (77%). Single chamber pacemaker was the most implanted (61.7%). Success implantation was obtained in 90% of cases. The main operative complication was the lead displacement in 5% of our patients, followed by local infection in 2 cases (3.3%). The post operative mortality was 3.3%. Conclusion : Permanant cardiac pacing is the only effective treatment for major atrio‑ventricular blocs. This technique is now possible in our country with good results and a low complication rate
