Abstract:
Objective To evaluate safety and effect of percutaneous balloon mitral valvuloplasty(PBMV) for patients with rheumatic mitral stenosis and left atrial thrombi.Methods PBMV was performed in 27 patients with rheumatic mitral stenosis and left atrial thrombi. 19 cases of left atrial fresh thrombi revealed by transesophageal echocardiography (TEE) received warfarin orally for 3-6 months before PBMV. Results PBMV was successful in all cases of mitral stenosis and left atrial thrombi. Left atrial fresh thrombi was completely resolved in 9 cases and became smaller chronic organized thrombi in 10 cases after warfarin anticoagulation treatment among 19 cases of left atrial fresh thrombi revealed by TEE. In 5 cases of left atrial chronic organized thrombi shown only transthoracic echocardiography and without anticoagulation treatment, one case had cerebral embolism. No complication occurred in other cases.Conclusions The study showed that patients with rheumatic mitral stenosis and atrial fibrillation should have routine TEE. PBMV for rheumatic mitral stenosis with left atrial thrombi after anticoagulation treatment is safe and effective.
