Radiofrequency catheter ablation in the left atrial posteroseptal region successfully eliminated 'slow-fast' atrioventricular nodal reentrant tachycardia after unsuccessful attempts on the right side.
Case Report (n=1)
Does radiofrequency ablation of the slow pathway in the left atrial posteroseptal region eliminate AVNRT in a patient with unsuccessful right-sided ablation?
Left-sided ablation of the slow pathway may be an effective alternative for AVNRT when traditional right-sided ablation fails.
RF catheter ablation is highly effective in eliminating atrioventricular nodal reentrant tachycardia by targeting the slow pathway in the posteroinferior part of Koch's triangle in the right atrium. We report here a patient in whom "slow-fast" atrioventricular nodal reentrant tachycardia was eliminated only by ablation of the slow pathway in the left atrial posteroseptal region at the level of the mitral annulus after unsuccessful attempts at the traditional site on the right side.
Jaı̈s et al. (Mon,) conducted a case report in Atrioventricular nodal reentrant tachycardia (n=1). Radiofrequency catheter ablation in the left atrial posteroseptal region vs. Traditional site on the right side (prior unsuccessful attempts) was evaluated on Elimination of atrioventricular nodal reentrant tachycardia. Radiofrequency catheter ablation in the left atrial posteroseptal region successfully eliminated 'slow-fast' atrioventricular nodal reentrant tachycardia after unsuccessful attempts on the right side.
