Suicide left ventricle describes the development of dynamic intraventricular gradients after aortic valve replacement due to acute hemodynamic changes that happen after relieving the obstruction leading to hemodynamic collapse. This is a rare complication in transcatheter aortic valve replacement and is underreported in surgical aortic valve replacement (SAVR). We present the case of a male patient who presented with suicide left ventricle after SAVR.

BACKGROUND

Takayasu Arteritis (TA) is a rare, primary large-vessel vasculitis frequently leading to stenosis and less commonly, aneurysm formation. Saccular aneurysms of the aortic arch in patients with TA are fatal, have rarely been reported and represent a significant technical challenge due to the difficult anatomical location and need for protection of the cerebral circulation. Concomitant intracerebral aneurysms in patients with TA are extremely uncommon and have mostly been documented in very few case reports in literature.

CASE DISCUSSION

We present a case of a 31 year-old Filipino female with recurrent chest and neck pain radiating to the upper back. Computed tomographic (CT) angiography demonstrated a large saccular aortic arch aneurysm without branch stenosis. CTA of the cerebral circulation likewise demonstrated multiple, saccular, intra-cerebral aneurysms. She underwent hybrid thoracic arch repair with supra-aortic debranching via mini-sternotomy and proximal ligation of the left common carotid artery and staged endovascular aortic arch replacement with coil embolization of the ostial-to-proximal left subclavian artery segment. Post-operative aortogram showed optimal repair with thrombosed aneurysmal sac, optimal graft position, no endoleaks and preservation of cerebral circulation. Patient improved symptomatically post-procedure and remained symptom-free during follow-up after six months. Careful review of local literature suggests that this is the first Philippine TA case with a saccular aortic arch aneurysm successfully managed in this manner.

CONCLUSION

Saccular aortic arch aneurysms in patients with Takayasu are unusual and presence of concomitant multiple cerebral saccular aneurysms have rarely been reported in literature. This case highlighted that hybrid endovascular arch repair in patients with TA is feasible, minimally invasive and effective.
