For systemic diseases like rheumatoid arthritis, systemic lupus erythematosus (SLE), systemic sclerosis, systemic vasculitis, myopathies, and mixed connective tissue diseases, cardiac disease is a major contributing factor for morbidity and mortality. The cardiovascular manifestations are the result of various pathophysiological components, which complicate management. Furthermore, the signs and symptoms can be subtle and missed due to the complex nature of the underlying condition. As a result, various imaging approaches play an imperative role in diagnosis and prognosis. The evolving role of these modalities could lead to risk stratification and improved therapies in the future. In conclusion, our review article will highlight the role of cardiac imaging in the evaluation of cardiac involvement for systemic diseases.

Patients admitted to the hospital can develop thrombocytopenia due to multifactorial causes. It can be pseudo-thrombocytopenia or true thrombocytopenia. Among patients admitted for chest pain, coronary angiography (CAG) is a common diagnostic test to evaluate patients for coronary artery disease (CAD). Normally, patients undergoing angiogram receive antiplatelets and anticoagulants pre-catheterization, and platelet aggregation inhibitor agents are sometimes used during and after CAG like in patients with high thrombus burden. Glycoprotein IIb/IIIa receptor inhibitors are a type of platelet antiaggregant agents that can cause severe thrombocytopenia in few cases. We present a case of a 68-year-old patient who came to the emergency department with inferior wall ST-segment elevation myocardial infarction and underwent angiography and had percutaneous coronary intervention (PCI) done. He was administered tirofiban during the angiogram that caused acute severe thrombocytopenia decreasing platelets count to 4000/microliter within one day. Patients' platelets gradually recovered after platelets transfusion.

We report a case of non-bacterial thrombotic endocarditis in a 52-year-old woman due to ovarian cancer that was complicated by acute ischemic stroke through pulmonary arteriovenous malformation. Echocardiography showed tricuspid valve vegetation and a positive bubble study that revealed pulmonary arteriovenous malformation in the absence of patent foramen ovale. The patient opted for palliative management and was discharged home with comfort care.

Coronavirus disease 2019 (COVID-19) grew to pandemic proportions in 2020. Research has shown that the causative virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), uses the angiotensin-converting enzyme II (ACE-II) receptor to attack host cells. These ACE-II receptors are present essentially in all organs, acting as a route of entry for SARS-CoV-2 to cause a wide variety of manifestations. There is growing research showing the neurologic effects of COVID-19. There have been several cases of encephalopathy, stroke, and encephalitis associated with COVID-19, however, intraventricular hemorrhages (IVH) have rarely been reported. Here we present a case of an IVH in the setting of COVID-19. A 32-year-old male with no past medical history, and not taking any medications, presented to the emergency room after acute onset loss of consciousness. Inflammatory markers were elevated, and computerized tomographic (CT) of the head and chest showed an intraventricular hemorrhage and bilateral interstitial infiltrates, respectively. Although possibly coincidental, this may represent a rare extrapulmonary fatal manifestation of COVID-19. With the growing evidence of neurologic presentations in patients with COVID-19, clinicians should maintain a high index of suspicion for COVID-19 to cause fatal extrapulmonary manifestations.
