An Unexpected Case of Severe Arrhythmogenic Right Ventricular Cardiomyopathy.

We present the case of a previously healthy 14-year-old boy who experienced two episodes of lightheadedness while sitting under the sun. The patient did not experience syncope and denied experiencing any other symptoms. Moreover, he exhibited great functional capacity. An electrocardiogram showed T-wave inversions in leads V1 to V4. Subsequent echocardiogram and cardiac magnetic resonance imaging confirmed the diagnosis of arrhythmogenic cardiomyopathy with severe features. Arrhythmogenic cardiomyopathy is a disorder characterized by fibrofatty degeneration of the myocardium and is a common cause of sudden cardiac death. This case highlights the significance of early investigation in any child who presents with seemingly benign symptoms, as they may be indicative of a serious cardiac disease.

Association Between Positive Troponin and Fear of Earthquakes: A Retrospective Study.

Introduction The association between natural disasters and cardiovascular events has been well-established. However, the impact of earthquakes on cardiac health, and the role of fear in this association, remains unclear. This study aims to examine the association between positive troponin levels, indicating cardiac ischemia, and fear of earthquakes among Emergency Room patients at a referral center in Beirut, Lebanon. Materials and methods This is a retrospective study conducted on patients who presented to the Emergency Room with suspected cardiac symptoms and were ordered a troponin level after the Kahramanmaras earthquake that occurred on the sixth of February 2023 and affected many neighboring countries, including Lebanon. A control group was taken from the same period in 2022 (January-February) and from the period prior to the earthquake (January up to 6 February 2023). Patients were divided into three groups: the first group (group 1) comprised patients who presented during January and February 2022 (period 1). The second group (group 2) included patients who presented from January up to the sixth of February 2023, when the Kahramanmaras earthquake occurred (period 2). The third group (group 3) consisted of patients who presented after the earthquake until the end of February 2023 (period 3). Patients who consented to participate in the study were sent a questionnaire to assess their Fear of Earthquake Scale (FES), chief complaints, date of presentation to the Emergency Room, past medical history, and other socio-demographic data. Results Our study involved 1410 participants, with 782 belonging to group 1, 470 to group 2, and 158 to group 3. The mean age was 62.96 ± 17.87 for the total population and 63.9 ± 18.49 for patients of group 3. The number of positive troponin results was higher during period 3 (62% of participants) in comparison to period 2 and 1 (22.1% and 28.5% of participants respectively) (p<0.001). Positive troponin was significantly more common among patients who are non-smokers (53%, p-value <0.001), with a negative family history of premature cardiac diseases (93.9%, p-value <0.05), previously healthy (46.9%, p-value <0.001) and presenting to the Emergency Room for dyspnea or palpitations (17.3% each, p-value <0.001). In addition, patients who tested positive for troponin had a higher mean FES (27.89 ± 1.23 versus 20.47 ± 6.02) and a higher mean age (71.07 ± 14.33 versus 52.25 ± 18.69) in comparison to those who tested negative for troponin (p-value <0.05). Conclusion This study suggests that fear of earthquakes may be associated with cardiac ischemia, as indicated by positive troponin levels. Healthcare providers should be aware of the potential impact of natural disasters on cardiovascular health and take measures to address patients' fears and concerns.

From Cardiac Mystery to Dental Discovery: Resolving Recurrent Infection in a Prosthetic Heart Valve Patient.

We present the case of a 71-year-old female with a history of surgical bioprosthetic aortic valve replacement who developed a liquefactive abscess near the mitral valve trigone following Streptococcus gallolyticus bacteremia. The patient initially presented with dyspnea and symptoms of an upper respiratory tract infection. A trans-esophageal echocardiogram revealed mitral valve vegetation and a possible source of sepsis near the prosthetic aortic valve. However, it was the identification of multiple silent dental abscesses during a routine dental check-up that led to the resolution of the patient's symptoms and the eradication of the infectious process. This case highlights the importance of considering dental infections as a potential cause of recurrent bacteremia and infectious complications in patients with prosthetic heart valves.

Persistent Atrium Standstill Post Atrial Fibrillation Ablation Therapy.

Atrial standstill is a rare condition in which the atrium loses its mechanical contraction with or without losing the electrical conduction. In this report, we discuss a case of a 64-year-old male patient with a history of hypertrophic cardiomyopathy (HCM) and persistent refractory atrial fibrillation (AF). He underwent ablation therapy with a successful return to sinus rhythm. However, post-procedure echocardiography imaging showed the absence of left atrium mechanical activity. We aim to highlight the importance of assessing atrial mechanical activity by imaging after sinus cardioversion in order to treat any preventable complications promptly.

Congenital Partial Absence of Pericardium in an Elderly Patient.

Patients with a complete absence of pericardium require no intervention as they are mostly asymptomatic. Due to the risk of herniation, patients with partial absence of pericardium tend to present with symptoms and may benefit from treatment. We report a case of an elderly patient who presented for severe colitis and was incidentally found to have a partial absence of the pericardium on the right side of the heart.
