Percutaneous closure of an iatrogenic ventricular septal defect following transcatheter aortic valve implantation.

ABSTRACT: Transcatheter aortic valve implantation (TAVI) has been increasingly used in symptomatic patients with severe aortic stenosis who are at high risk for conventional open heart surgery. However, it might be associated with serious complications. We report a case with an iatrogenic ventricular septal defect as a rare complication following TAVI procedure. <Learning objective: To highlight a rare complication of iatrogenic ventricular septal defect (VSD) following transcatheter aortic valve implantation procedure and its treatment with percutaneous interventional VSD closure.>.

Project description:BackgroundA rare, but serious, complication following transcatheter aortic valve replacement (TAVR) is the occurrence of an iatrogenic ventricular septal defect (VSD).Case summaryWe describe a case of an 80-year-old female who was referred with severe aortic stenosis for TAVR. Following thorough evaluation, the heart team consensus was to proceed with implantation via a transapical approach of an ACURATE neo M 25 mm valve (Boston Scientific, Natick, MA, USA). The valve was deployed harnessing transoesophageal echocardiographic (TOE) guidance under rapid pacing with post-dilation. Directly afterwards a very high VSD close to the aortic annulus was detected. As the patient was haemodynamically stable, the procedure was ended. The next day another TOE revealed a shunt volume (left-to-right ventricle) between 50% and 60%. Because the defect was partly located between the stent struts of the ACURATE valve decision was made to fix this leakage with implantation of a further valve and we chose an EVOLUT Pro 29 mm (Medtronic Inc., Minneapolis, MN, USA). The valve-in-valve was implanted 2-3 mm below the lower edge of the first valve, more towards the left ventricular outflow tract (LVOT) with excellent result: VSD was reduced to a very small residual shunt without any hemodynamic relevance.

The implantation depth of the second valve (EVOLUT Pro 29 mm) was slightly deeper in the left ventricular outflow tract; and (D) transoesophageal echocardiography after the valve-in-valve procedure showing a small residual shunt.
