RESUMEN
BACKGROUND: Transcatheter aortic valve replacement (TAVR) has increased in utilization since its approval for management of aortic stenosis patients across all risk strata. We report a rare case of aortic valve leaflet avulsion after balloon expandable TAVR managed with urgent surgery. CASE PRESENTATION: A 78-year-old male underwent TAVR complicated by avulsion of the native aortic valve leaflet's left coronary cusp. He was taken for urgent surgery for cusp resection to prevent thromboembolic complications. CONCLUSIONS: Native aortic valve leaflet avulsion should be suspected during TAVR in instances of extreme hemodynamic instability after balloon aortic valvuloplasty. As TAVR expands in lower risk patients, surgeons should have a low threshold to intervene surgically to treat native leaflet avulsion or other complications.

Systemic lupus erythematosus (SLE) and antineutrophil cytoplasmic antibody-associated vasculitis (AAV) overlap syndrome is an inflammatory disorder with a mixed presentation that is characterized by clinical features of both SLE and AAV. Although renal disease predominates, any organ system in the body may be affected. Neurologic manifestation in patients with SLE-AAV overlap syndrome is rare and has only been previously documented as cerebral ischemia. We report a patient with SLE-AAV overlap syndrome diagnosed based on clinical, serologic and biopsy-proven histologic findings who presented with subarachnoid hemorrhage (SAH) secondary to ruptured right anterior cerebral artery aneurysm. To the authors' knowledge, this is the first reported case of SLE-AAV overlap syndrome diagnosed in a patient with a SAH due to an intracranial aneurysm. Neurologic involvement in patients with SLE-AAV overlap syndrome is uncommon and has not been well-studied. Clinicians who encounter patients with neurologic signs that present with symptoms and a serologic profile that correspond to both SLE and AAV criteria, should consider the association between SLE-AAV overlap syndrome and a hemorrhagic stroke, specifically SAH.
