A case report of a combined implantation technique of a cardioverter-defibrillator in an infant with long QT syndrome type 8 (Timothy's syndrome).

We present a case of successful implantation of a cardioverter-defibrillator (ICD) using combined technique in a child with Timothy's syndrome. Due to high risk of sudden cardiac death (SCD) such patients often need ICD for primary or secondary prevention but implantation technique in young children remains controversial. The subcutaneous cardioverter-defibrillators could be an option in some cases, however, reliable cardiac pacing should be implemented for patients with bradyarrhythmias.

Sleep Apnea and Atrial Fibrillation: Clinical Features and Screening Diagnostic Options.

Introduction: Obstructive sleep apnea (OSA) is associated with an increased risk of hypertension, coronary artery disease, heart failure (HF), and atrial fibrillation (AF).

Materials And Methods: A total of 179 patients aged 34-81 years were included in the study. The median age was 63 years (interquartile range: 56-69 years).

Repair of Congenital Right Atrial Aneurysm Associated With Wolff-Parkinson-White Syndrome in a 5-Year-Old Girl.

This report describes our experience with a 5-year-old girl who had an extremely rare presentation of a right atrial aneurysm and associated Wolff-Parkinson-White syndrome. Before being referred to our department, she underwent an ineffective radiofrequency ablation for repeated episodes of paroxysmal supraventricular tachycardia that were causing dizziness, palpitations, and chest discomfort. We resected the aneurysm with good results; she was doing well and was in normal sinus rhythm at the time of her 1-year follow-up visit.

Video-assisted thoracoscopic pacemaker lead placement in children with atrioventricular block.

Background: The pacemaker lead placement is presented as one of the most appropriate procedures in children with a complete atrioventricular block (AVB). Despite the fact that video-assisted thoracic surgery (VATS) for epicardial lead placement has demonstrated positive results as to the feasibility, safety, and efficacy in adults, its role in pacemaker implantation in children remains unclear.

Aim: This study sought to assess the intermediate-term outcomes of video-assisted thoracoscopic pacemaker lead placement in children with complete AVB.

[Not Available].

Purpose: to assess specificities of course of the long-QT syndrome in children before and after implantation of cardioverter-defibrillator (ICD), and optimization of indications to ICD-therapy.

Materials And Methods: We included in this study 48 children with long-QT syndrome from 44 unrelated families (28 boys and 20 girls), who underwent ICD implantation at the mean age 11.8±3.

[Left ventricular diastolic dysfunction in endovascular treatment of atrial fibrillation in patients with preserved ejection fraction].

Aim: To study prevalence of left ventricular diastolic dysfunction (LVDD) and to evaluate the effect of pulmonary vein catheter isolation on left ventricular (LV) diastolic function in patients with paroxysmal and persistent forms of atrial fibrillation (AF).

Materials And Methods: 109 patients with paroxysmal (n=90; 82.6 %) and persistent (n=19; 17.

[The Brugada Syndrome in a Teenager].

The Brugada syndrome (BS) belongs to the group of hereditary channelopathies associated with elevated risk of sudden death (SD) in the absence of structural heart diseases. The disorder phenotypically manifests by specific electrocardiographic pattern, associated with ventricular tachycardia (VT). VT can be accompanied by loss of conscience, and after transformation to ventricular fibrillation result in SD.

Outcomes of Cryoballoon Ablation in High- and Low-Volume Atrial Fibrillation Ablation Centres: A Russian Pilot Survey.

Purpose: The results of cryoballoon ablation (CBA) procedure have been mainly derived from studies conducted in experienced atrial fibrillation (AF) ablation centres. Here, we report on CBA efficacy and complications resulting from real practice of this procedure at both high- and low-volume centres.

Methods: Among 62 Russian centres performing AF ablation, 15 (24%) used CBA technology for pulmonary vein isolation.

[General anesthesia tools in endovascular surgery of the conductive heart system].

The anesthetic management course was analyzed in 224 patients who underwent nonvascular surgeries on the conductive heart system. Analgesic and anti-stress techniques, which do not affect the intracardial conductivity and ensure the successful outcome of surgery with spontaneous or auxiliary ALV, were designed on the basis of research. The above schemes were introduced in practice with their efficiency being confirmed.

[Anesthesiology in the surgical treatment of supraventricular tachyarrhythmias].

Different anesthesias were used in 197 patients operated for supraventricular tachiarrhythmias through a transvenous access. Hypnoanalgesia based on preventive injection of a potent nonnarcotic antiinflammatory agent xefocame (lornoxicame), drip infusion of propofol (2-3 mg/kg/h), and bolus injection of dormicum under conditions of spontaneous respiration proved to be the best method.

[Experience with the implantation of sensory multiple programmable pacemakers of the Siemens firm].

The paper summarizes the experience on 27 implantations of sensory multiprogrammable pacemakers (two-chamber Synchrony-II and one-chamber Sensolog-III) produced by Siemens-Elema. The implantations were performed in the Moscow Cardiostimulation Center in 1993. Primary pacemaker implantation was performed in 19 patients, 8 patients needed the replacement of one-chamber pacemakers because of the power source exhaustion or circulatory insufficiency.
