Acute success of cryoablation of left-sided accessory pathways: a single institution study.

13 Dec 2009 OBJECTIVE: To compare the acute success and recurrence rate of cryoablation for left-sided accessory pathways (AP) with controls who underwent radiofrequency ablation (RFA) at the same institution. BACKGROUND: Catheter cryoablation of ... Read more...

A nonsense SCN5A mutation associated with Brugada-type electrocardiogram and intraventricular conduction defects.

30 Aug 2009 Mutations of SCN5A, gene-encoding alpha-subunit of cardiac sodium channel, can cause mixed phenotypes of Brugada syndrome (BrS) and cardiac conduction diseases (CCD). We have identified a nucleotide change of SCN5A (4178T > G), which results in a ... Read more...

Is electrocardiography a reliable tool for identifying patients with isthmus-dependent atrial flutter?

29 Jun 2009 AIMS: To verify the reliability of the surface ECG to discriminate between cavotricuspid isthmus-dependent atrial flutter (CTI-AFL) and non-CTI-AFL. METHODS AND RESULTS: We reviewed the ECGs of 186 consecutive patients who underwent catheter ... Read more...
