Controlled Clinical Trial
Prognostic predictors of sinus rhythm control by amiodarone and electrical cardioversion in patients undergoing percutaneous transluminal mitral valvuloplasty for rheumatic atrial fibrillation.
Conversion to sinus rhythm (SR) is rarely attempted in patients with rheumatic atrial fibrillation (AF) because the length of AF duration and the dilation of left atrium (LA) make maintenance of SR difficult. In this study, predictors of the successful maintenance of SR with amiodarone and electrical cardioversion in rheumatic AF patients receiving percutaneous transluminal mitral valvuloplasty (PTMV) were identified. ⋯ In rheumatic AF patients receiving PTMV, the successful maintenance of SR with amiodarone and electrical cardioversion can be predicted by the degree to which LA size is reduced and MV area is increased.

Transthoracic 2-dimensional (D) echocardiography (echo) is often used to assess tricuspid regurgitation (TR) after implantation of permanent pacemakers. However, its ability to define the precise anatomical relationship between the tricuspid valve and the pacemaker lead is quite limited. ⋯ Three-D echo precisely depicted the entrapment of the lead shaft in the fused and fibrotic septal and posterior tricuspid leaflets. The patient underwent tricuspid valve annuloplasty and the symptoms of right heart failure improved soon after the operation.
