[Vascular access-site infections in percutaneous cardiac interventions: A significant risk?].

Vascular access site infections are infrequent and rarely reported as a potential complication of percutaneous cardiac intervention. A case of access site infection is reported with a literature review. Femoral access is mainly concerned in some circumstances: delayed sheath withdrawal, vascular complications (hematoma, false-aneurysm, arteriovenous fistula), or use of hemostatic closure device.

Missing diagnosis of preexcitation syndrome on ECG: clinical and electrophysiological significance.

Unlabelled: Electrocardiographic criteria of preexcitation syndrome are sometimes not visible on ECG in sinus rhythm (SR). The purpose of the study was to evaluate the significance of unapparent preexcitation syndrome in SR, when overt conduction through accessory pathway (AP) was noted at atrial pacing.

Methods: Anterograde conduction through atrioventricular AP was identified at electrophysiological study (EPS) in 712 patients, studied for tachycardia (n=316), syncope (n=89) or life-threatening arrhythmia (n=55) or asymptomatic preexcitation syndrome (n=252).
