Arrhythmogenic Right Ventricular Cardiomyopathy
Arrythmogenic right ventricular (RV) cardiomyopathy (ARVC) is a cardiomyopathy characterized pathologically by fibrofatty replacement primarily of the RV and clinically by life-threatening ventricular arrhythmias in apparently healthy young people. The prevalence of the disease has been estimated at 1 in 5,000 individuals, although this estimate will likely increase as awareness of the conditio...
متن کاملArrhythmogenic right ventricular cardiomyopathy.
Arrhythmogenic right ventricular cardiomyopathy (ARVC) has evolved from postmortem pathology at to a diagnosable clinical condition, and holds promise for definitive genetic diagnosis. Its prevalence is between 1/1,000 and 1/5,000, with 10% of deaths occurring before age 19 and 50% before age 35. When analyzed against age-specific norms, the electrocardiography (ECG) and signal-averaged ECG (SA...
متن کاملRight ventricular mechanical dispersion is related to malignant arrhythmias: a study of patients with arrhythmogenic right ventricular cardiomyopathy and subclinical right ventricular dysfunction.
AIMS We evaluated if right ventricular (RV) mechanical dispersion by strain was related to ventricular arrhythmias (VT/VF) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) and if mechanical dispersion was increased in so far asymptomatic mutation carriers. METHODS AND RESULTS We included 69 patients, 42 had symptomatic ARVC and 27 were mutation positive asymptomatic fam...
متن کاملArrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia1
Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is characterized by the patchy replacement of myocardium by fatty or fibrofatty tissue. These changes lead to structural abnormalities including right ventricular enlargement and wall motion abnormalities that can be detected by echocardiography, angiography, and cine MRI. ARVC/D is a genetically heterogeneous disorder, since it...
متن کاملArrhythmogenic right ventricular dysplasia/cardiomyopathy.
The heart is a 4-chambered pump that propels blood simultaneously to the lungs and the rest of the body by means of coordinated muscular contraction. Various diseases can affect the heart muscle and cause it to become weak, thus decreasing its ability to pump blood adequately. Disease that weakens the heart muscle is called cardiomyopathy. Some causes of cardiomyopathy are viral infections of t...
