Kounis syndrome following COVID-19 vaccination.

Coronary stent thrombosis is a life-threatening condition induced by multiple factors, including allergic reactions. A 64-year-old man presented with stent thrombosis in the left anterior descending artery and multiple cardiorespiratory arrests immediately after the first dose of the BNT162b1 mRNA vaccine. He underwent emergent percutaneous coronary intervention.

Takotsubo cardiomyopathy following a simple partial seizure.

A 67-year-old woman presented to the emergency department for a simple partial seizure of her left upper and lower limbs that lasted for 1 hour and ultimately resolved before her presentation. She had no history of coronary artery disease, and her neurological exam was normal. Five hours later, she complained of chest pain.

Acoustic energy and cardiac electrophysiology: Ultrasonic cardiac pacing and novel shockwave ablation catheters.

Sonic shockwaves (SSW) can cause cardiac pacing. This observation first came to notice with the early urologic lithotripters and later with the cumulative use of shockwaves to treat calcified coronary lesions. There have been multiple observations of cardiac pacing and tachyarrhythmias occurring during SSW delivery using the Shockwave Intravascular Lithotripsy system.

Large paradoxical embolus through a patent foramen ovale following arteriovenous graft thrombectomy.

An 86-year-old man with end-stage renal disease on hemodialysis with an arteriovenous fistula in his left upper extremity presented to his hemodialysis session with thrombosis of his arteriovenous fistula. The patient underwent surgical thrombectomy. The patient later showed evidence of peripheral embolization and livedo reticularis.

Atrial Flutter Following Shockwave Intravascular Lithotripsy During Percutaneous Intervention of Left Anterior Descending Disease.

A 72-year-old woman undergoing percutaneous intervention to a calcified proximal left anterior descending (LAD) coronary artery lesion using Shockwave Intravascular Lithotripsy (S-IVL) developed new atrial flutter. She then returned to sinus rhythm after treatment with amiodarone. S-IVL can cause cardiomyocyte depolarization.
