ABSTRACT
A 39-year-old male was admitted in the emergency room with chest pain. He had been given the second dose of Pfizer-BioNTech COVID-19 vaccine 3 days before. The patient denied taking any other medication beyond the usual. He didn't feel sick in the previous days/weeks. Laboratory studies revealed elevated serum levels of troponin and C-reactive protein. An autoantibody screen and a serologic panel to detect common viruses were negative. A cardiac MRI showed myocardial edema/inflammation and confirmed the diagnosis of perimyocarditis which was considered to be a consequence of COVID-19 vaccination. Physicians should be aware of the possibility of cardiovascular complications after COVID-19 vaccination.
ABSTRACT
We report a case of a 73-year-old female patient admitted to the surgical department for a splenic abscess. She had a history of a mechanical aortic valve implanted two years earlier. During the diagnostic work-up, the patient underwent a transesophageal echocardiogram that revealed the presence of multiple paravalvular abscesses, establishing the diagnosis of prosthetic valve endocarditis. A few days later, the echocardiogram was repeated due to a new-onset systolic-diastolic murmur. A large pseudoaneurysm and significant periprosthetic regurgitation were now noted and the patient was referred for cardiac surgery. The microbiologic exam revealed the presence of Streptococcus milleri, usually found in the gastrointestinal flora and a known pathogenic agent of endocarditis. Interestingly, the patient had had a foreign body (bone fragment) removed from her esophagus a few weeks earlier, which was the probable portal of entry for this infective endocarditis.

OBJECTIVE: Retrospective analysis of the initial experience at our department with an implantable loop recorder (ILR) for the evaluation of patients with recurrent syncope, palpitations or dizziness. METHODS: We studied ten patients aged 31-65 (52.3) years referred to our center after an inconclusive evaluation that included ECG, Holter monitoring, events recorder, stress test, echocardiogram and electrophysiological study. Seven patients had structural heart disease. We used a Reveal Plus (Medtronic, USA) ILR, which allows up to 41 minutes of electrocardiographic recording, over a period of 24 months, patient or device activated, according to the programmed parameters. Follow-up was scheduled every three months or after every event activated by the patient. Symptoms and recorded events were analyzed. RESULTS: Eight patients activated events, out of a total of 45 episodes, and five patients reported two or more symptoms. Dizziness was reported by five patients (24 episodes), palpitations by three (seven episodes), syncope by three (seven episodes) and nonspecific symptoms by five patients (seven episodes). The first symptom occurred between the twelfth day and the sixth month after implantation. Four episodes (three syncope and one dizziness) occurred with significant AV conduction disturbance (complete or high grade AV block) and in 41 episodes no rhythm or AV disturbance was recorded. Thirty events were automatically activated. There were no device-related complications. None of the patients died during follow-up.
