Aortic iatrogenic perforation during transseptal puncture and successful occlusion with Amplatzer ductal occluder in a case of mitral paravalvular leak closure.

Complications of transseptal puncture are significant and potentially life threatening. Aortic perforation is one of these complications and it needs to be repaired immediately. We report the case of a 48-year-old female with a history of rheumatic mitral valve disease. She underwent three previous mitral valve replacements. Her last echocardiogram reported an anterolateral leak in the mitral prosthesis. Catheterization was performed. During the procedure, when attempting to perform transseptal puncture, catheterization was complicated by a forcefully puncture of the aortic root by the Brockenbrough needle followed by an immediately advancement of an 8-Fr Mullins sheath. We decided to leave the 8-Fr sheath in the aortic root recognizing the danger of removing the sheath and finally we advanced a 6/4 mm Amplatzer ductal occluder (ADO I) through the Mullins sheath and under fluoroscopy and TEE guidance we achieved a successful deployment of the device and closure of the perforation. Subsequently, the paravalvular leak was closed with an Amplatzer Vascular Plug (AVP III 10/5 mm). There are only three cases of a similar technique for the same injury in which the authors describe successful closing of aortic perforation with percutaneous closure devices. Our case is the first described during a mitral paravalvular leak closure. It is also the first to describe a different technique of leaving the Mullins sheath in the aortic root and advancing the Amplatzer device through it to achieve successful closure of the aortic perforation. We preferred the percutaneous closure over open-heart repair. © 2015 Wiley Periodicals, Inc.
