Regression of large atrial thrombi and coronary neovascularizations with conventional anticoagulation in mitral stenosis--a case report.

The authors report a case of angiographically documented multiple coronary neovascularizations originating from the left circumflex artery (LCX) and coursing toward multiple thrombi located in the left atrium in a patient with severe mitral stenosis. The thrombi as well as the neovascularizations underwent near-complete resolution with 4 weeks' anticoagulation therapy with warfarin maintaining an international normalization ratio of 3.5. Percutaneous mitral balloon valvuloplasty was performed successfully without complications.
