'A series of unfortunate events': a case report of infective endocarditis resulting from ventricular arrhythmia ablation.

Oral cavity infections are common but often overlooked, mainly when the RFA procedure is urgent. A thorough physical examination, including a dental check-up, is crucial to minimize the risk of potential infection of the endocardial tissue and maximize the benefits of the therapy. Still, it is possible that the myocardial infection was not a result of oral cavity infection but a result of other undiagnosed and untreated infection. Contamination of the procedure site with patients' own microbiota or foreign microorganisms by the medical personnel is also a likely and unfortunate scenario. The presented case highlights the significance of not only prophylaxis, screening, and treatment of possible inflammation sites before RFA but also the need for sustaining sanitary standards and sterile conditions.
