Acute impact of atrial fibrillation on pacemaker lead-induced tricuspid regurgitation: Case report.

ABSTRACT: We report a case of worsening lead-induced tricuspid regurgitation (TR) after new-onset atrial fibrillation (AF) evaluated using three-dimensional (3D) transthoracic echocardiography (TTE) from admission through TR improvement. An 84-year-old man experienced worsening lead-induced TR with new-onset AF, acutely resulting in low output syndrome. Less invasive interventions, such as rhythm control therapy and diuretics administration worked effectively. However, 3DTTE revealed consistent restricted motion of the septal leaflet with lead impingement. Right heart dilatation due to AF and worsened TR led to incomplete closure of other leaflets and tricuspid annular dilatation, which caused further deterioration of the TR. According to the course of our case, new-onset AF can cause acute worsenin
