However, in some cases we see misplacement of pacemaker leads which is most often related to the presence of underlying cardiac anomalies. We report the case of misplacement of a pacemaker lead into the left ventricle of a 56-year-old patient paced in VVI/R mode and with a tined type pacemaker lead because of a symptomatic complete atrioventricular block. Electrocardiogram showed a pacemaker-generated rhythm with a right bundle branch block pattern. Chest X-ray showed the pacemaker lead located relatively high in relation to the diaphragm. Echocardiography visualized the pacemaker lead in the left heart chambers (atrium and ventricle), hence confirming its aberrant course. Further, the defect causing its passage to the left heart chambers was a sinus venosus atrial septal defect. The patient reported no complication related to the misplacement of the lead. After a brief period of oral anticoagulation, the lead was inserted into the right ventricle by percutaneous technique.

Objective To study the prevalence of rheumatic heart
disease (RHD) in schools (locally referred to as ‘daaras’)
located in the city of Dakar and its suburbs using both
clinical examination and echocardiography.
Methods This is a cross-sectional study conducted
from 9 August to 24 December 2011 involving 2019
pupils, aged between 5 and 18 years selected from the
16 ‘daaras’ of the Academic Inspectorate (Inspection
d’Académie) of the city of Dakar and its suburbs.
Anamnestic, clinical and echocardiographic data were
collected and entered into a questionnaire designed for
the study. The World Heart Federation criteria for
echocardiographic diagnosis were used to diagnose
RHD. p<0.05 was considered statistically significant in
bivariate analysis.
Results About 60.1% of the pupils were men and the
mean age was 9.7±3.3 years. 10 cases of definite RHD
were detected, prevalence being 4.96 per 1000 (95% CI
2.4 to 9.1). This prevalence was five times higher with
echocardiographic screening compared with clinical
screening. 23 cases (11.4 per 1000) of borderline forms
were detected. The populations at risk of definite RHD
identified in our study were children over 14 years
(p<0.001), those with recurrent sore throat ( p=0.003)
and those residing in the suburbs of the city of Dakar
(p<0.001).
Conclusion Our study shows a relatively high
prevalence of RHD. Reducing its prevalence should focus
on the implementation of appropriate policies, targeting
at-risk populations and focusing on raising awareness
and early detection.
