Why the study?
The authors sought to illustrate the anatomical distance between the true mitral annulus and coronary sinus during trans-septal ablation, which can impact procedure efficacy and safety after valve surgery.
Can trans-septal ablation be successfully performed for a left concealed accessory pathway in a patient with prior surgical mitral valve repair and mechanical aortic valve replacement?
Can trans-septal ablation be successfully performed for a left concealed accessory pathway in a patient with prior surgical mitral valve repair and mechanical aortic valve replacement?
Trans-septal ablation can be successfully performed for left accessory pathways in patients with prior mitral valve repair, highlighting the importance of recognizing the anatomical distance between the true mitral annulus and coronary sinus.
Supports trans-septal left AP ablation after valve surgery; leaves open need for larger series on safety and alternatives.
We presented a case of severe aortic regurgitation and moderate mitral regurgitation s/p aortic valve replacement and mitral valve repair. Deterioration of tachyarrhythmia attacks was noted. In EP study, left lateral accessory pathway with orthodromic atrioventricular reentrant tachycardia was identified. We successfully ablated the accessory pathway by trans-septal approach. Even though trans-septal approach currently is a daily routine of invasive interventional electrophysiologists, in this case, we want to emphasize and illustrate the distance between true mitral annulus and coronary sinus. Unrecognizing this concept could result in efficacy and safety of catheter-based therapy.
