Takotsubo Cardiomyopathy in the Setting of Hypertrophic Cardiomyopathy Following Pacemaker Implantation.

The presentation of Takotsubo cardiomyopathy (TC) has overlapping features with acute coronary syndrome (ACS), though traditionally developing from different triggers, including both physical and emotional. Additionally, TC is associated with multiple comorbidities and sequelae. We present a multifactorial case of a 73-year-old female with underlying hypertrophic cardiomyopathy who presented with a high-degree atrioventricular (AV) block requiring permanent pacemaker (PPM) placement and subsequently developed TC. Patients with hypertrophic obstructive cardiomyopathy (HCM) have been theorized to have increased cardiac sympathetic activity and sensitivity. Thus, this case report demonstrates the increased relative risk of patients with underlying HCM in the development of TC during PPM placement.
