Abstract:
BACKGROUND: Percutaneous mitral balloon valvuloplasty(PMV) is a good treatment modality for patient with mitral stenosis(MS). But it is considered relatively contraindicated in patients with left artrial thrombi because of high risk of embolism. Limitted studies have suggested the feasibility of PMV in patients with left atrial appendage(LAA) thrombi. This study was performed to evaluate the feasibility and safty of PMV in patients with LAA thrombi using Inoue balloon under the transesophageal echocardiographic (TEE) monitoring. METHOD: PMV was performed in 5 patients diagnosed as MS with LAA thrombi from October, 1995 to July, 1996. Four cases were female, and one case was male. Their mean age was 525(46-58years old). Two of them had history of cerebrovascular accident(CVA). The duration of anticoagulant treatment was 6-49 moths. All patients underwent PMV using Inoue balloon catheter under the TEE monitoring. RESULTS: EKG finding of all 5 patients were atrial fibrillation(Af). Their mitral valve score were 5-10(Mean score was 82). Transmitral mean pressure gradient was decreased from 14.62.1 to 5.82.0mmHg, and mitral valve increased from 0.840.43 to 1.720.19 after PMV. There was no procedure related complication. In 3 cases of them LAA thrombi diappeared in the follow up TEE. In two patients, the LAA thrombi were calcified and remained unresolved at the time of follow up TEE( 6month-and 12 month-F/U, eath). CONCLUSION: Although the reported number of PMV in patients with LAA thrombi is small in this study, we believe that, with special precaution and TEE monitoring, LAA thrombi is no longer an absolute contraindication to PMV.
