ARTICLE HIGHLIGHTS
Case characteristics

Patient with severe calcific aortic stenosis presented with worsening symptom of shortness of breath.

Clinical diagnosis

Patient was diagnosed as symptomatic severe aortic stenosis clinically.

Differential diagnosis

Left ventricular outflow tract obstruction, sub-valvular aortic stenosis and supra-valvular aortic stenosis are the differentials.

Laboratory diagnosis

ECG showed intermittent paced rhythm due to pacemaker and chest x-ray showed sternal wires due to previous coronary artery bypass graft.

Imaging diagnosis

Echocardiography and computer tomography showed severe calcific aortic stenosis with perimembranous interventricular septum aneurysm extending into left ventricular outflow tract.

Pathological diagnosis

Patient had congenital heart defect which included interventricular septum aneurysm extending into left ventricular outflow tract with acquired severe calcific stenosis of tri-leaflet aortic valve.

Treatment

The patient was treated with transcatheter aortic valve replacement .This was achieved in our case by implanting the prosthetic valve more distally into the left ventricular outflow tract (LVOT) requiring apposition of the Edwards SAPIEN XT skirt at annulus with most of the valvular metallic frame in supra-annular position.

Related reports

During transcatheter aortic valve replacement, normally the conventional recommendation is to implant the device with 50% above and 50% below native leaflet insertion .We had 80% aortic and 20% ventricular ratio of the device at the level of leaflet insertion of the native valve.

Term explanation

LVOT denotes left ventricular outflow tract obstruction and TAVR denotes transcatheter aortic valve replacement.

Experiences and lessons

The transcatheter aortic valve replacement can be done in patients having high surgical risk with perimembranous interventricuar septum aneurysm by implanting the device more distally into the LVOT.
