Outcomes of ventricular tachycardia (VT) ablation in structural heart disease have been reported to differ by sex. Whether this is due to differences in the underlying arrhythmogenic substrates among patients with nonischemic cardiomyopathy (NICM) remains unclear.

Name: Heart rhythm
In patients with nonischemic dilated cardiomyopathy (NIDCM), native T1, partition coefficient (λ), and extracellular volume fraction (ECV) mapping may offer prognostic values beyond late gadolinium e...
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiomyopathy characterized by ventricular arrhythmias and sudden death in the young and in competitive athletes. The deleteriou...
Arrhythmogenic Cardiomyopathy (ACM) is associated with arrhythmias and risk of sudden death. Mutations in genes encoding proteins of cardiac intercalated discs account for about 60% of ACM cases, but ...
The reason for recurrence of ventricular arrhythmia (VA) after catheter ablation in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) is not clear.
Background The new designation of arrhythmogenic cardiomyopathy defines a broader spectrum of disease phenotypes, which include right dominant, biventricular, and left dominant variants. We evaluated ...
This study evaluates mechanisms of arrhythmogenicity in hypertrophic cardiomyopathy, in comparison to patients with well-understood arrhythmogenic substrate (ischemic cardiomyopathy), as w...
This study assesses the value of arrhythmogenic substrate identification and elimination by catheter ablation to prevent recurrent ventricular arrhythmias and sudden cardiac death in a ser...
The purpose of this trial is to study the genetic and phenotypic aspects of Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C), and determine the impact of genetic testing ...
The purpose of this study is to determine whether a larger dose of the aldosterone antagonist spironolactone combined with a lower dose of an ACE inhibitor is more effective in reverse lef...
Patients with ischemic cardiomyopathy (left ventricular ejection fraction
A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).
A congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the RIGHT VENTRICLE wall and loss of myocardial cells. Primary injuries usually are at the free wall of right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.
Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.
An autosomal dominant inherited form of HYPERTROPHIC CARDIOMYOPATHY. It results from any of more than 50 mutations involving genes encoding contractile proteins such as VENTRICULAR MYOSINS; cardiac TROPONIN T; ALPHA-TROPOMYOSIN.
A set of opposing, nonequilibrium reactions catalyzed by different enzymes which act simultaneously, with at least one of the reactions driven by ATP hydrolysis. The results of the cycle are that ATP energy is depleted, heat is produced and no net substrate-to-product conversion is achieved. Examples of substrate cycling are cycling of gluconeogenesis and glycolysis pathways and cycling of the triglycerides and fatty acid pathways. Rates of substrate cycling may be increased many-fold in association with hypermetabolic states resulting from severe burns, cold exposure, hyperthyroidism, or acute exercise.
