Ablation som förstahandsval vid supraventrikulära takykardier. Goda resultat och få komplikationer i studie av 2 207 konsekutiva patienter
Sammanfattning
We present results in 2,207 consecutive patients ablated for AV nodal reentrant tachycardia (AVNRT; 1,004 patients; 61% women), atrio-ventricular reentrant tachycardia (AVRT; 584 patients; 38% women) and cavotricuspid atrial flutter (AFL; 619 patients; 21% women) between 2000 and 2007. Success rate was 98% for AVNRT (redo 6%), 96% for AVRT (redo 4%) and 97% for AFL (redo 10%). There were four inadvertant AV-block III necessitating pacemaker treatment and four uncomplicated tamponades occurred. Success rate was higher for women than for men in AVNRT (99% vs 95%; p<0.01) but lower in AFL (90% vs 97%; p<0.01). 266 patients were 70 years or older. There was no difference in this group in regard to success rate, complications or recurrences. We conclude that ablation can be recommended as first line therapy in patients with AVNRT, AVRT and FFL regardless of age, as success rate is high and severe complications are very rare.
