Effusive-constrictive calcific pericarditis associated with Streptococcus salivarius. Case report and review of the literature.

We report the case of a 40-year-old patient presenting with a 6-month history of dyspnea and edema, with significant worsening of his clinical manifestations for the 2 weeks before admission to our department. During this 14-day preadmission period, continuous positive airway pressure (CPAP) was prescribed elsewhere for management of a working diagnosis of obstructive sleep apnea. The patient presented to us hemodynamically compromised.

Paraseptal accessory connections in the proximity of the atrioventricular node and the His bundle. Additional observations in relation to the ablation technique in a high risk area.

Introduction: Paraseptal pathways, namely, accessory connections (AC) in the vicinity of the atrioventricular node (AVN) and the bundle of His, are associated with a high risk of complete atrioventricular block (AVB) during transcatheter radiofrequency ablation (RFA) in the Electrophysiology Laboratory. In previously reported series of ablation of paraseptal ACs, the coexistence of multiple ACs in this high-risk region has rarely been mentioned.

Methods And Results: We studied 15 patients undergoing RFA of paraseptal ACs 2 of whom had dual pathways with an additional midseptal pathway revealed after the elimination of the anteroseptal target AC.
