A Rare Case of Cardiac Myxoma With Moyamoya Phenomenon: A Disease or Syndrome?

Moyamoya disease (MMD) is a rare, idiopathic, progressive, obstructive, vasculopathy affecting primarily the terminal portions of the intracerebral internal carotid arteries, typically at the base of the brain. It is more commonly seen in people of East Asian descent. The moyamoya phenomenon refers to the characteristic appearance of the tangle of fine blood vessels, also described as a puff of smoke.

Cardiac Catheterization and Outcomes for Elderly Patients Hospitalized With Heart Failure.

Background: Heart failure affects over 6 million people in the United States (US) with limited evidence to support the use of cardiac catheterization. The benefit of its use remains mostly as expert opinion. This study intends to assess the benefits and risks of cardiac catheterization in elderly patients admitted for heart failure.

Cardiac Hemangioma: A Rare Tumor Presenting as Postpartum Chest Pain.

Pulmonary embolism, peripartum cardiomyopathy, acute myocardial infarction, aortic dissection, anxiety, and gastroesophageal reflux disease are known causes of chest pain during the peripartum period. A cardiac tumor is a rare cause of chest pain during this time period. While cardiac myxomas during pregnancy have been reported, cardiac hemangiomas are exceptionally rare.

A Case Report of Takotsubo Cardiomyopathy With Myxedema Coma.

The exact pathogenesis of Takotsubo cardiomyopathy (TC) or broken heart syndrome is unclear. However, it is known to be a stress-induced cardiomyopathy. There are multiple causes of TC, and thyroid dysfunction is supposed to be one of the causes.

A Young Adult With Essential Thrombocythemia Presenting as Myocardial Infarction.

Essential thrombocythemia (ET) is a myeloproliferative neoplasm involving the clonal proliferation of platelets. It is Philadelphia negative and is associated with Janus kinase 2 (JAK2), calreticulin (CALR), or myeloproliferative leukemia virus oncogene (MPL) mutations. The resultant platelets have quantitative and qualitative defects, making them more sticky and prone to thromboembolism.

A Rare Presentation of Granulomatosis With Polyangiitis with Multiple Cardiac Valvular Insufficiencies.

Granulomatosis with polyangiitis (GPA), earlier known as Wegener's granulomatosis, is an autoimmune inflammatory disorder that causes necrotizing vasculitis of small- and medium-sized blood vessels. It primarily affects the upper respiratory tract, lungs, and kidneys. Most of the cardiac involvement tends to be subclinical and is often not clinically apparent with involvement of the conduction pathway; myocarditis, pericarditis, or coronary artery involvement are associated with increased morbidity and mortality.

A Rare Case of Horseshoe Kidney With Multiple Atrial Myxomas Presenting as Cerebrovascular Accident.

Myxomas are benign tumors of mesenchymal origin, containing a few pluripotent cells in the myxomatous stroma. They usually present at 30-40 years of age and are more common in females than males. These tumors mostly arise in the atria and protrude into the atrial lumen.

Symptomatic Myocarditis Post COVID-19 Vaccination.

There are few major adverse events after the coronavirus disease 2019 (COVID-19) vaccination. However, increasing cases of myocarditis and pericarditis are being reported to the Vaccine Adverse Event Reporting System (VAERS) in young people, primarily after the second dose of messenger RNA (mRNA) COVID-19 vaccines. We present a case series of myopericarditis post mRNA (Moderna) and myocarditis post vector-based (Johnson & Johnson) COVID-19 vaccines.

Recognizing Rare Sequelae of Epstein-Barr Virus Myocarditis Leading to Dilated Cardiomyopathy and Acute Congestive Heart Failure With Multivalvular Regurgitation.

Myocarditis is associated with a wide range of infections, most commonly viral (cytomegalovirus), bacterial, and parasitic (). Epstein-Barr virus (EBV) rarely causes myocarditis, which is a life-threatening complication. Autoantibodies against cardiac myocytes activate the complement system and cause diffuse myocyte necrosis.

The Epidemiology and Clinical Manifestations of Takayasu Arteritis: A Descriptive Study of Case Reports.

Takayasu's arteritis is a rare form of chronic inflammatory disorder involving large vessels, with an unclear etiology. Common early signs and symptoms are weakness, malaise, and fever. Takayasu's arteritis mainly involves the aorta and its branches as well as the subclavian and carotid arteries.

Transient Complete Heart Block in a Patient With COVID-19.

SARS-CoV-2, also known as COVID-19, was first identified in Wuhan, China. Symptoms of COVID-19 are fevers, dry cough and less commonly gastrointestinal (GI) symptoms such as diarrhea that occur in 2 to 14 days of exposure. Infection with COVID-19 leads to hospitalizations due to respiratory compromise.

Complete Dissection of the Interventricular Septum Following Myocardial Infarction.

In this report, we present a case of interventricular septal dissection (IVSD) following inferior wall myocardial infarction (MI) in a 64-year-old patient; the patient ultimately recovered after prompt resuscitation and intervention, despite the high mortality associated with these cases. A 64-year-old male with a history of hypertension and obesity was brought to the hospital following an episode of syncope at home. He had been experiencing chest tightness over the past few days prior to the admission.
