Takotsubo syndrome after a minimally invasive tooth extraction in a patient without dental phobia: A case report

Takotsubo syndrome (TTS) is a rare, stress-induced acute cardiac disorder. Its precipitating factors include emotionally or physically stressful events and exogenous and endogenous adrenaline. In this report, we describe a case of atypical TTS in a 73-year-old woman who reported no dental fear and required acute cardiac care in an outpatient setting. She underwent routine extraction of an upper left premolar under local anesthesia. She reported heart palpitations after the injection, and the procedure was completed in 15 min. After presenting symptoms of sweating, pale skin, vomiting, low blood pressure, and ST-segment elevation, cardiologists ordered echocardiography, coronary angiography, and ventriculography. Upon receiving a TTS diagnosis, the patient was hospitalized and administered an intra-aortic balloon pump and beta-blocker. Her symptoms resolved, and she was discharged with no sequelae. We found no precipitating factors in the progression of TTS in this case, which suggests that TTS can develop in the absence of precipitating factors. All general dentists and oral surgeons should recognize the possible risk of TTS, even during minimally invasive dental procedures, such as routine extractions in patients without dental phobia.
