Key result
Transfemoral transcatheter aortic valve implantation following permanent pacemaker implantation was safely performed and resolved symptoms in a patient with severe aortic stenosis and hypertrophic obstructive cardiomyopathy.
Why the study?
Concomitant HOCM is associated with substantially worse in-hospital outcomes after TAVI for AS, and optimal management strategies remain poorly reported.
Does TAVI following PPM implantation successfully treat severe AS complicated with HOCM in a single patient?
Case Report (n=1)
No
Does TAVI following PPM implantation successfully treat severe AS complicated with HOCM in a single patient?
TAVI following permanent pacemaker implantation may be a successful management strategy for patients with severe aortic stenosis complicated by hypertrophic obstructive cardiomyopathy.
Objective: Transcatheter aortic valve implantation (TAVI) is an established therapy for aortic stenosis (AS). However, concomitant hypertrophic obstructive cardiomyopathy (HOCM) was associated with substantially worse in-hospital outcomes including cardiogenic shock, renal failure, and death in patients undergoing TAVI. Furthermore, there were few reports on optimal management for AS complicated with HOCM. In this case, we report a Japanese man with severe AS and concomitant HOCM, who was successfully treated by TAVI following PPM implantation.

Takamura et al. (2020) conducted a case report in Severe aortic stenosis complicated with hypertrophic obstructive cardiomyopathy (n=1). Transcatheter aortic valve implantation following permanent pacemaker implantation was evaluated on Procedural safety and symptom resolution. Transfemoral transcatheter aortic valve implantation following permanent pacemaker implantation was safely performed and resolved symptoms in a patient with severe aortic stenosis and hypertrophic obstructive cardiomyopathy.
