Abstract
Cardiomyopathies are myocardial diseases in which there is structural and functional disorder of the heart muscle, in the absence of coronary artery disease, hypertension, valvular disease and congenital heart disease. Cardiomyopathies are grouped into specific morphological and functional phenotypes: dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy and unclassified cardiomyopathies. Patients with dilated and hypertrophic cardiomypathy are prone to the development of congestive heart failure in the perioperative period. Also, patients with hypertrophic and arrhythmogenic right ventricular cardiomyopathy are prone to arrhythmias in the perioperative period. Preoperative evaluation includes history, physical examination, ECG, chest radiography, complete blood count, electrolytes, creatinine, glomerular filtration rate, glucose, liver enzymes, urin analysis, BNP and echocardiographic evaluation of left ventricular function. Drug therapy should be optimized and continued preoperatively. Surgery should be delayed (unless urgent) in patients with decompensated or untreated cardiomyopathy. Preoperative evaluation requires integrated multidisciplinary approach of anesthesiologists, cardiologist and surgeons.
