RESUMEN
Primary cardiac tumors are extremely uncommon but metastases can result from direct invasion from the mediastinum, hematogenous spread or extension of the tumor into the vena cava and the right atrium. A CASE REPORT: A 37-year-old male with no previous history of chronic diseases was admitted to the hospital due to non-specific chest discomfort, non-productive cough and weakness lasting for several weeks. Physical examination was unremarkable except for tachycardia and bibasal rales. Chest radiogram revealed multiple pulmonary lesions suggesting metastases. A mass in the right adrenal gland was found on abdominal ultrasound and CT scan. In addition, a pathological lesion in the inferior vena cava extending to the right atrium was detected. Echocardiography revealed a pedunculated mass measuring 2.3x1.5 cm, located in the right atrium, which originated from the inferior vena cava. During the diastole, it prolapsed to the right ventricle but did not significantly affect blood flow through the tricuspid valve. Adrenal tumor biopsy revealed adrenocortical cancer and treatment with mitotane was started. After a seizure episode, brain MRI was performed and showed metastases surrounded by edema. Due to the patient's poor general condition and progression of the disease during mitotane treatment was later withdrawn and the patient was referred for the hospice care where he died 2 months later. CONCLUSIONS: Adrenocortical cancer is a rare malignant neoplasm with an estimated annual incidence of 4-12 cases per 1,000,000. It is characterized by a tendency for local invasion and multiple metastases to the lungs, liver and bones. In the literature, there are only a few cases of adrenocortical cancer directly extending from the inferior vena cava to the right atrium.

The direct-current electric shock is considered to be safe treatment of arrhythmias and rarely leads to serious hemodynamic complications. A 62-year-old patient was admitted to the hospital due to a first symptomatic episode of atrial fibrillation. Patient was diagnosed with apical hypertrophic cardiomyopathy 20 years ago. Transoesophageal echocardiography was performed to exclude an atrial thrombus followed by electrical cardioversion with restoration of sinus rhythm. After 6 hours symptoms of pulmonary oedema developed. The patient's condition improved after furosemide administration. As the possible cause of the oedema, inotropic effect of administered propafenone and atrial stunning were considered. The atria seem to be responsible for important part of forward cardiac output even during AF, especially in cardiomyopathies. Contractility deterioration of the left atrium (stunning) along with earlier resumption of the right atrium contractile function could be associated with hemodynamic instability causing pulmonary oedema in subjects with hypertrophied myocardium. It is necessary to take into consideration the atrial function while administrating antiarrhythmic drugs, especially those with negative inotropic effect.

A 30-year-old man was admitted to the intensive care unit after a suicide attempt with respiratory difficulties, tremor, sinus tachycardia and significant hypokalemia. On examination, the patient was lucid, fully conscious and did not exhibit positive symptoms. Sings were not typical for overdosing olanzapine, alprazolam and alcohol as declared by the patient. Additional anamnesis revealed high doses of ingested clenbuterol, a selective ß2-adrenergic agonist. Due to its anabolic and lipolytic properties, clenbuterol has become a commonly abused drug in bodybuilding industry and is not routinely detected by toxicology screens. This is the first known report of suicide attempt by clenbuterol overdosing.
