Case Summary:
A patient who underwent mechanical aortic and mitral valve replacement developed three paravalvular leaks 10 months later. We located the tracks by puncturing the apex cordis under transoesophageal echocardiography guidance alone and puncturing the femoral artery guided by fluoroscopy. Three paravalvular leaks were occluded with a hybridization method simultaneously. The patient was followed up for 24 months and maintained a good condition.
Conclusion:
Multiple paravalvular leaks after double valve replacement can be occluded in patients by the use of different approaches under echocardiographic guidance alone.
