The aim of the study was to elucidate the effects of cardiac resynchronization therapy (CRT) on ventricular tachycardias in patients with dilated cardiomyopathy and to analyze the prospects of radionuclide diagnostic methods for prediction of life-threatening arrhythmias in the presence of therapy. The study included 70 patients (mean age 55 12 years) aged 32 to 75 years with dilated cardiomyopathy, NYHA FC III heart failure, left ventricular (LV) ejection fraction (EF) of 30.1 3.8%, and end-diastolic volume (EDV) of 220.7 50.9 mL. Group 1 comprised 35 patients (50%) diagnosed with paroxysms of ventricular tachycardia, while Group 2 consisted of 35 patients (50%) without episodes of ventricular tachycardia. After one year of CRT, positive clinical changes were documented in all patients: LV EF increased to 42.8 4.8% (p 0.001); functional class of heart failure decreased to II; LV EDV decreased to 197.9 47.8 mL (p 0.005). The patients whose EF increased by 14% and EDV decreased by 35 mL during one-year CRT had no episodes of ventricular tachycardia. The patients, whose paroxysms of ventricular tachycardia persisted during the entire period of the study, showed EF increase by 9% and EDV decrease by 13 mL. The second stage of the study consisted in evaluating the effects of myocardial metabolism defects (MMD). No ventricular tachycardia episodes were registered in patients whose MMD became less than 15% during CRT; if the size of DMM exceeded 15%, paroxysms of ventricular tachycardia were observed. Thus, efficacious CRT in patients with dilated cardiomyopathy results in a statistically significant reduction of the number of ventricular tachycardia episodes. The improvement of fatty acid metabolism contributes to a decrease in the number of ventricular tachycardia episodes in the course of CRT.

Key Words Dilated Cardiomyopathy

Purposes: Describe the morphological and diastolic function of left ventricular changes in the patients with dilated cardiomyopathy (DCM) on US, X-ray findings, and Evaluate the correlation between morphology and diastolic function of left ventricular. Materials and method: Cross sectional study from Dec 2009 to Aug 2010, on 39 patients with dilated cardiomyopathy were evaluated at the University Hospital of Hue College of Medical and Pharmaceutical. Results: 1. X-ray and US findings characteristics of DCM is significantly increased in diameter of L, H and mG; LVM, LVMI, LVDd and LAD. 2. The pression of pulmonary artery has been significantly increased with redistribution pulmonary arteries in 61.5% cases and 23.1% have reversed pulmonary artery distribution. 3. DCM have diastolic dysfunction in 100% patients, including severe disorders to 61.5%; the restrictive dysfunction has ratio E/A>2 and E/Em average was 23.89± 17.23. 4.The correlation between the morphology and function in DCM: the diameter of H and L on the X-ray, LAD and ratio LA/AO on US correlated with the level of diastolic dysfunction (p< 0.05). All three radiographic parameters on the radio standard (H, L, the index Cardio/Thoracic) and LVDd on US have negative correlated with EF and FS with p <0.05.

Abstract Background Dilated cardiomyopathy (DCM) is a disease of the heart muscle characterized by ventricular dilation and a left ventricular ejection fraction of less than 40%. Unlike hypertrophic cardiomyopathy (HCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC), DCM-causing mutations are present in a large number of genes. In the present study, we report a case of the early age of onset of DCM associated with a pathogenic variant in the RBM20 gene in a patient from India. Case presentation A 19-year-old Indian male diagnosed with DCM was suggested for heart transplantation. His ECG showed LBBB and echocardiography showed an ejection fraction of 14%. He had a sudden cardiac death. A detailed family history revealed it to be a case of familial DCM. Genetic screening identified the c.1900C>T variant in the RBM20 gene which led to a missense variant of amino acid 634 (p.Arg634Trp). Conclusion To the best of our knowledge, the variant p.Arg634Trp has been earlier reported in the Western population, but this is the first case of p.Arg634Trp in an Indian patient. The variant has been reported to be pathogenic at an early age of onset; therefore, close clinical follow-up should be done for the family members caring for the variant.
