[Characteristics of coronary artery involvement and probability of appropriate discharges of cardioverter-defibrillator implanted for primary prevention of sudden cardiac death].

Purpose: To assess characteristics of involvement of coronary vascular bed in patients with ischemic heart disease and cardioverter defibrillator (CD) implanted for primary prevention of sudden cardiac death (SCD) with and without history of appropriate implantable (I) CD therapies.

Material And Methods: We examined 64 survivors of myocardial infarction (MI) (60 men, 4 women) with CD implanted for primary prevention of SCD. Mean duration of follow up after CD implantation was 19.

[Possibility and necessity of catheter ablation of ventricular arrhythmias in patients with ischemic heart disease and implanted cardioverter-defibrillator].

The article describes the data of efficiency of catheter ablation of substrate of ventricular arrhythmias, performed in patients with ischemic heart disease and implanted cardioverter- defibrillator (ICD) in order to decrease the number of ICD therapy. An assessment of the follow-up study of 32 patients was made, the catheter ablations were performed in 10 of them. The statistically reliable number of ICD therapy and at the same time both "shock" and antitachycardia pacing decreased in the group of catheter ablation.

[Complications high frequency catheter destruction of heart conduction pathways].

An analysis of 490 operations in 442 patients with different variants of supraventricular and ventricular tachycardia was made. Complications developed in 23 cases (4.7%).

[New methods in angiocardiographic diagnosis of arrhythmogenic dysplasia of the right ventricle].

Arrhythmogenic dysplasia of the right ventricle (ADRV) is a congenital pathology of the heart resulting in the appearance of ventricular tachycardia that considerably increases risk of sudden death in young people. Up to now, however, the diagnostic criteria of this pathology have not been completely developed. An original method was used to study specific features of the regional contractile function (RCF) of the right ventricle and its diagnostic potentials in ADRV.
