RESUMO
Catheter radiofrequency ablation of focal atrial fibrillation was successfully performed in a patient after closure of interventricular septal defect with a xeno-pericardial patch and plastic of tricuspid valve. The case demonstrates feasibility of carrying out such interventions under intracardiac echocardiographic guidance in patients with disturbed anatomy and complicated access to the left atrium.

The article contains review of possibilities of the method of intracardiac echocardiography (ICE) in clinical electrophysiology, delineation of indications to its use, and perspectives of development of this technology. Characteristics of technical variants of the method and special features of their application are also given. Technique of performance of interventions under ICE control is described in detail. Foreign experience of ICE use is summarized, and own experience is presented.

RESUMO
The last studies show the renin angiotensin aldosterone system plays an important role in atherosclerotic processes. Vasoconstriction and sodium and water retention, due to angiotensin II and aldosterone promote atherosclerotic processes. Theres recent evidence from animal and clinical studies to consider angiotensin II as a mediator of inflammation, which induces atherosclerotic plaque development and heart remodeling. Also angiotensin II causes endothelial dysfunction by inducing cytokine and chemokine secretion. The pharmacological blockade of the renin angiotensin system has positive influence on clinical outcomes of patients with cardiovascular diseases independently of the blood pressure lowering effect. This review summarizes studies about the role of angiotensin converting enzyme (ACE) inhibitors, angiotensin II receptor antagonists (ARA) and renin inhibitors in vascular inflammatory processes in atherosclerosis.
