Extensive papillary muscle calcification is uncommon and only scarce literature about causes and the clinical significance is available, whereas small calcific deposits are common findings in elderly people and are located most commonly at the apex. Papillary muscle calcification has been associated with coronary artery disease, dilated cardiomyopathy, mitral valve disease, hypercalcemia, and increased calcium phosphate product in end stage renal disease. We reported a rare case of extensive calcification of anterolateral papillary muscle diagnosed by echocardiography and multidetector computed tomography.

Hypercalcemia is a known cause of heart rhythm disorders, however its association with ventricular arrhythmias is rare. The authors present a case of a fifty-three years old male patient with a ischemic and ethanolic dilated cardiomyopathy, and severely reduced ejection fraction, carrier of cardiac resynchronization therapy (CRT) with cardioverter defibrillator (ICD), admitted in the emergency department with an electrical storm, with multiple appropriated ICD shocks, refractory to antiarrhythmic therapy. In the etiological investigation was documented severe hypercalcemia secondary to primary hyperparathyroidism undiagnosed until then. Only after the serum calcium level reduction ventricular tachycardia was stopped.

We report a case of primary hyperparathyroidism with hypercalcaemia in a 16-year-old boy who had spontaneous attack of ventricular tachycardia. To our knowledge, presentation of ventricular tachycardia caused by primary hyperparathyroidism in such a young patient has not been reported in medical literature so far.

In endocrine diseases, hormonal changes, electrolyte abnormalities, and the deterioration of heart structure can lead to various arrhythmias. In diabetic patients, hypoglycemia, hyperglycemia, and hypokalemia can trigger arrhythmias, and diabetic cardiomyopathy can also cause electrical and structural remodeling to form substrates for arrhythmias. The risk of atrial fibrillation (AF) increases in hyperthyroidism; however, the prevalence of ventricular arrhythmias in hypothyroidism is higher. Besides AF and ventricular tachycardias, bradycardias and atrioventricular blocks can also be seen in pheochromocytoma due to the desensitization of adrenergic cardiovascular receptors. The correction of metabolic and electrolyte disturbances in patients with adrenal cortex disease should be the main approach in the prevention and treatment of arrhythmias. Early initiation of treatment in patients with acromegaly seems to decrease the development of cardiac remodeling and ventricular arrhythmia. Early and late after depolarizations due to hypercalcemia in hyperparathyroidism can lead to life-threatening ventricular arrhythmias. This elegant position paper provides important recommendations regarding prevention and treatment of arrhythmias for specific endocrine disorders.
