AI Article Synopsis
- - A 56-year-old woman diagnosed with atrial fibrillation had severe left ventricular dysfunction due to rapid conduction through an accessory pathway, which is a sign of Wolff-Parkinson-White syndrome.
- - After performing electrical cardioversion, a short PR interval and delta wave were observed, indicating the presence of the accessory pathway.
- - Following radiofrequency catheter ablation of the pathway, the patient's left ventricular function quickly improved.
Article Abstract
We report the case of a 56-year-old woman with newly diagnosed atrial fibrillation (AF) and severe left ventricular (LV) dysfunction caused by rapid conduction via an accessory pathway (AP), mimicking left bundle branch block, as the first clinical manifestation of Wolff-Parkinson-White (WPW) syndrome. Electrical cardioversion of the AF revealed a short PR interval and a delta wave, which was positive in leads I, II, aVL, and V2 and negative in lead V1 with a transition zone between V1 and V2. Radiofrequency catheter ablation of a superoparaseptal pathway was accompanied by rapid recovery from LV systolic dysfunction.

Introduction: We describe two patients with right supero-paraseptal accessory pathway (SPAP) who developed left ventricular dysfunction associated with an increased degree of ventricular pre-excitation and frequent orthodromic reciprocating tachycardia (ORT) due to worsening atrioventricular (AV) node conduction.
Methods And Results: Case 1: 48-year-old female with a history of normally functioning mechanical mitral valve, CABG, and ventricular pre-excitation that worsened after her open heart surgery. She presented with frequent palpitations with documented supraventricular tachycardia (SVT) and found to have a new left ventricular dysfunction with decrease in left ventricular ejection fraction (LVEF) from 55% to 46% with dyssynchrony.

Surgeons, when dividing bypass tracts adjacent to the His bundle, considered them to be 'anteroseptal'. The area was subsequently recognized to be superior and paraseptal, although this description is not entirely accurate anatomically, and conveys little about the potential risk during catheter interventions. We now describe the area as being para-Hisian, and it harbours two types of accessory pathways.

- Larger tip cryoablation catheters can weaken the signal at their distal ends, which lowers the accuracy of mapping certain arrhythmias (supero paraseptal accessory pathways).
- Using high-resolution mapping techniques is recommended to enhance both the safety and effectiveness of the procedure.
- Improved mapping can lead to better identification and treatment of abnormal electrical pathways in the heart.
