A 48-year-old man presented to the emergency department (ED) with exertional chest pressure associated with palpitations and lightheadedness. He was found to have non-sustained ventricular tachycardia (NSVT) in the ED, which resolved spontaneously. Given his history of hyperlipidaemia, unknown family history due to being adopted and episode of NSVT in the ED, he underwent cardiac catheterisation, which showed non-obstructive coronary artery disease and distal left anterior descending artery myocardial bridge (MB). The patient subsequently underwent ECG treadmill stress test with reproduction of chest pressure and NSVT. The patient was referred to cardiac surgery for definitive management of symptomatic MB and underwent resection of MB.

Coronary angiography is the golden choice for coronary artery disease evaluation and management. However, as with any invasive procedures, there is a risk of complications. We are reporting a case of 69-year-old male with past medical history of cardiac bypass surgery, CHF, hypertension, and hyperlipidemia who was admitted to the hospital to evaluate his chest pain. He had treadmill stress test that showed ischemic induced exercise. Patient underwent coronary angiography that showed proximal complete occlusion of the RCA with a patent graft. At the end of the procedure, the patient did not wake up and remained minimally responsive. An urgent brain MRI was ordered and showed infarctions consistent with an artery of Percheron infarction. Later, patient has improved slowly and was discharged home. We briefly here discuss this rare complication including the risk factor, clinical presentation, and the management.

A 65-year-old male with a history of coronary artery disease and ankylosing spondylitis presented with focal ECG changes and elevated cardiac biomarkers suggestive of an acute lateral ST-elevation myocardial infarction. Emergent coronary angiography surprisingly showed non-obstructive coronary artery disease. Further workup including a cardiac MRI, viral serologies, and an endomyocardial biopsy was consistent with focal Coxsackie viral myocarditis. The patient subsequently developed recurrent, pulseless ventricular tachycardia requiring multiple rounds of ACLS, and his left ventricular ejection fraction acutely dropped from 55% to 20%. An emergent intra-aortic balloon pump was placed, and an intravenous lidocaine infusion and high-dose corticosteroids were started for the patient’s electrical storm and myocarditis, respectively. The patient was eventually discharged in stable condition with an implantable cardiac defibrillator. No further episodes of ventricular tachycardia were noted at six-month follow-up. In patients with acute ECG changes, elevated cardiac biomarkers, and no evidence of obstructive coronary artery disease, myocarditis should be considered as a leading diagnosis given the potentially life-threatening sequelae as seen in our patient.

Abstract Background Coronavirus disease 2019 (COVID-19) has been associated with myocardial involvement. Among cardiovascular manifestations, cardiac arrhythmias seem to be fairly common, although no specifics are reported in the literature. An increased risk of malignant ventricular arrhythmias and electrical storm (ES) has to be considered. Case summary We describe a 68-year-old patient with a previous history of coronary artery disease and severe left ventricular systolic disfunction, who presented to our emergency department describing cough, dizziness, fever, and shortness of breath. She was diagnosed with COVID-19 pneumonia, confirmed after three nasopharyngeal swabs. Ventricular tachycardia (VT) storm with multiple implantable cardioverter defibrillator (ICD) shocks was the presenting manifestation of cardiac involvement during the COVID-19 clinical course. A substrate-based VT catheter ablation procedure was successfully accomplished using a remote navigation system. The patient recovered from COVID-19 and did not experience further ICD interventions. Discussion To date, COVID-19 pneumonia associated with a VT storm as the main manifestation of cardiac involvement has never been reported. This case highlights the role of COVID-19 in precipitating ventricular arrhythmias in patients with ischaemic cardiomyopathy who were previously stable.
