Dysplasia of the tricuspid valve leading to recurrent atrial flutter and fibrillation: a case report.

ABSTRACT:

Background

Atrial flutter (AFL) is usually effectively treated by cavotricuspid isthmus (CTI) ablation. If AFL recurs despite ablation, there is risk of progression to atrial fibrillation (AF) and clinicians should consider underlying structural heart diseases. This consideration becomes especially critical when right-heart-chambers are dilated.

Case summary

A 50-year-old man presented with palpitations due to AFL. Fifteen years earlier, after polytrauma, mild tricuspid regurgitation (TR) and pericardial effusion had been diagnosed on transthoracic echocardiography (TTE). At present, TTE showed dilated right-heart-chambers and moderate TR. Despite two CTI-ablations, he developed AF for which he underwent pulmonary vein isolation (PVI). A further ablation was performed becaus
