- Patient initials or identifier number:
-Relevant clinical history and physical exam:
Dyspnoea of 1year duration; presently NYHA classII. Diagnosed to have severe aortic stenosis. Previous mechanical mitral valvereplacement 15 years back. Known CKD. Recurrent subdural hematoma- frontotemporoparietal chronic subdural hematoma and underwent rightfrontal burr hole and evacuation elsewhere on 20/09/2019. Right frontal burrhole re-exploration and right parietal burr hole and evacuation of recurrentchronic subdural hematoma on 17/10/2019. Heart team decision for TAVR
-Relevant test results prior to catheterization:
ECG-atrialfibrillation.ECHO:Aortic max gradient: 66.9 mmHgMean gradient: 42mmHgAortic valve area: 0.81 cm2
- Relevant catheterization findings:
Nosignificant coronary artery disease. Severe aortic stenosis. Mean transvalvular aortic gradient of40mmHg
- Procedural step:
Transfemoral route transcatheter aortic valveimplantation was done under conscious sedation. 2 proglides. During valve crossing, care was taken to ensure the wire did not pass through the mechanical mitral prosthesis (by observing in orthogonal views). View for pre dilatation was the angulation that showed maximum separation of the balloon. Pre-dilatation was done to assess balloon shifts and impression on the mechanicalmitral valve. A 27.5mm Myval (Meril lifesciences)- a novel balloon expandable valve, with additional 2ml volume added inthe balloon was deployed by very slow balloon inflation. Fluoroscopy time-27:58 min. Contrast volume- 135ml Visipaque.
- Case Summary:
Post procedure-Forcedsaline diuresis and fluid replacement, Serum creatinine 1-week post discharge-3.20 mg/dl (baseline-3.6mg/dl). Pre discharge ECHO- mean gradient across aortic valve: 13.0 mmHg;valve area- 2.0 cm2. NYHAclass 1 at discharge.
This case highlights feasibility of transcatheter aorticvalve implantation with a novel balloon expandable valve in a patient withaortic stenosis and prior mechanical mitral prosthesis with a short aorticannulus-mitral prosthesis distance.
