Limitations
First, because of the small population and absence of a control group receiving a traditional PM, the present results cannot be used to assess any causal relationship between the variables explored. However, this explorative study allowed the evaluation of the feasibility of an LP implantation in our clinical setting and in patients with broad clinical indications. Second, our center had a high volume of LP implantations and TLEs with experienced operators, which may have led to more favorable outcomes. The small sample size made it difficult to draw conclusions regarding the mortality in this population. Therefore, multicenter registries and studies with a large study population are essential in the future. Finally, though there were no sign of reinfection at the 6 months follow up, LP infection may occur at a later stage. Furthermore, we used available echocardiography, blood cultures, and clinical symptoms to identify device infection, the diagnosis of reinfection of the LP may have been missed.
