Brugada syndrome (BS) is an inherited cardiac disease with increased risk of ventricular tachyarrythmias, cardiac arrest and sudden death. BS is diagnosed on various criteria including specific electrocardiographic abnormalities in a structurally normal heart. Many drugs have been reported to induce fatal arrhythmias in patients with BS and in particular sodium channel blockers i.e. local anaesthetics such as bupivacaine. We report the anaesthetic management of two women with BS during caesarean section and provide a general discussion on the use of bupivacain for neuraxial blockade for patients with BS...

The abrupt cessation of effective cardiac function that is generally due to heart rhythm disorders can cause sudden and unexpected death at any age and is referred to as a syndrome called "sudden cardiac death" (SCD). Annually, about 400,000 cases of SCD occur in the United States alone. Less than 5% of the resuscitation techniques are effective. The prevalence of SCD in a population rises with age according to the prevalence of coronary artery disease, which is the most common cause of sudden cardiac arrest...

Costello syndrome is a rare genetic disorder characterised by growth and mental retardation, macrocephaly, short neck and macroglossia. Cardiac involvement can also occur in Costello syndrome and is presented in the form of hypertrophic cardiomyopathy, tachyarrythmias and valvular dysfunction. Nervous system involvement including ventriculomegaly, hydrocephaly and Chiari type 1 malformation are also common. Predisposition of papillomata and malignant tumours are high. General anaesthesia practice in patients with Costello syndrome may be complicated by difficult airway because of macrocephaly, short neck, macroglossia and oral or laryngeal papillomas...

We report a case of carcinoid syndrome requiring an emergency operation for an upper gastrointestinal perforation. A 46-year-old man had undergone left lower lobectomy for a lung carcinoid tumor seven years previously, and liver metastasis was found five years previously. He developed cutaneous flushing and watery diarrhea, and was diagnosed with carcinoid syndrome one year previously. Although he was treated with octreotid, his symptoms became worse and he was admitted to our hospital. During the hospital stay, he underwent an emergency operation for an upper gastrointestinal perforation...

PURPOSE: To determine whether monomorphic ventricular tachycardias (VTs) have different characteristics and/or responses to antitachycardia pacing (ATP) with respect to the indication-primary prevention (PP) versus secondary prevention (SP)-among ICD patients with left ventricular dysfunction. METHODS: We prospectively studied 551 VT (cycle length [CL] 329 ± 35 ms; PP 34%) occurring in 67 ICD patients with left ventricular dysfunction (LVEF 35 ± 8%). ICD programming was standardized, including ATP for slow (CL 400-321 ms) and fast VT (CL 250-320 ms)...

An implantable cardioverter defibrillator (ICD) can falsely recognize noise by monopolar electrocautery as tachyarrhythmia and deliver inappropriate antitachycardia therapy. Application of a clinical magnet on an ICD suspends antitachycardia therapy, but it has not been widely used for this purpose. A 67-year-old male underwent laryngopharyngectomy, cervical esophagectomy, right neck dissection, tracheostomy and reconstruction with free jejunal transplant for recurrent hypopharyngeal cancer. He had an ICD (PARADYM DR8550, Sorin) implanted below the left clavicle for ventricular tachycardia and prolonged QT syndrome...

Infectious gastroenteritis is one of the common causes of tachyarrythmia, malabsorbtion and growth retardation in children. Our recent studies have indicated that neonatal.cryptosporidial gastroenteritis is associated with long-term cardiomyocyte abnormalities. The aim of the present study was to find out how neonatal cryptosporidiosis of various severities affects cardiac anatomy and cardiomyocyte polyploidization, remodeling and HIF-1α expression. Using real-time PCR, cytometry, immunohistochemistry, image analysis and interatrial septum visual examination, we revealed that gradual increase in cryptosporidial invasion was associated with threshold changes...

INTRODUCTION: Persistent foetal tachyarrythmias complicated by hydrops fetalis carry a poor prognosis, with foetal death reported in excess of a quarter despite treatment. We present our experience with direct intraperitoneal amiodarone administration in eight hydropic foetuses with resistant supraventricular tachycardia. METHODS: Amiodarone was injected slowly into foetal peritoneal cavity under ultrasound guidance. All mothers were loaded with oral amiodarone before the procedure and maintained on it...

Cardiovascular complications are important in hyperthyroidism because of their high frequency in clinical presentation and increased mortality and morbidity risk. The cause of hyperthyroidism, factors related to the patient, and the genetic basis for complications are associated with risk and the basic underlying mechanisms are important for treatment and management of the disease. Besides cellular effects, hyperthyroidism also causes hemodynamic changes, such as increased preload and contractility and decreased systemic vascular resistance causes increased cardiac output...

BACKGROUND: Glycated proteins (advanced glycation endproducts, AGE) in tissue are associated with degenerative diseases. This study evaluated the role of sRAGE (soluble receptor for advanced glycation endproducts), a decoy receptor of AGEs in blood, for the outcome of patients after coronary artery bypass grafting (CABG). METHODS: A total of 90 patients undergoing CABG were analysed in two centres. Perioperative blood samples were collected before surgery up to 1 week postoperatively...

REVIEW
Andreas Pflaumer
Although most arrhythmias in children have a benign outcome, recurrent arrhythmic events have a significant impact on quality of life. Electrophysiology studies with ablation have good short-term success and an acceptably low complication rate. The long-term outlook for this patient group is incompletely defined, however. Factors that require special consideration in children include the need to limit the size, depth and number of lesions, and the radiation exposure incurred during fluoroscopy-guided catheters manipulation...

Refractory ventricular tachyarrythmias (VTs) are potentially life-threatening rhythms in patients with cardiomyopathies, particularly when they result in hemodynamic instability. Here we report two cases of patients with intractable ventricular tachyarrythmias that were unresponsive to anti-arrhythmic medications and repeated catheter ablation, and for whom concomitant cryoablation and left ventricular assist device implantation was successfully performed. Both patients tolerated the procedure well with no complications and were free from ventricular tachyarrythmias postoperatively...

Electrolyte disorders can alter cardiac ionic currents kinetics and depending on the changes can promote proarrhythmic or antiarrhythmic effects. The present report reviews the mechanisms, electrophysiolgical (EP), electrocardiographic (ECG), and clinical consequences of electrolyte disorders. Potassium (K⁺) is the most abundent intracellular cation and hypokalemia is the most commont electrolyte abnormality encountered in clinical practice. The most significant ECG manifestation of hypokalemia is a prominent U wave...

PURPOSE: It has been reported that elevation of asymmetric dimethylarginine (ADMA) concentration is involved in atrial fibrillation (AF) process. The purpose of this study was to determine whether ADMA concentration is related to recurrences of AF after catheter ablation. METHODS: A total of one hundred and thirty-eight patients with persistent AF (49.91 ± 7.23 years), but without known heart disease, who underwent successful mapping and catheter ablation were included...

We report a case of a 3-year-old boy who had undergone total cavopulmonary connection for repair of corrected transposition of the great arteries (cTGA), and developed intractable supraventricular tachyarrhythmia. The patient was in cardiogenic shock and did not respond to antiarrhythmic drugs and cardioversion, and we used extracorporeal life support (ECLS) to maintain hemodynamics. We used dexmedetomidine to block sympathetic activity. After administration of dexmedetomidine, tachycardia was improved, and the sinus rhythm returned...

Although symptomatic carbon dioxide (CO(2)) embolism is rare, it recognized as a potentially fatal complication of laparoscopic surgery. Sudden hemodynamic instability could be a CO(2) embolism especially during insufflation. A 65-year-old man received laparoscopic prostatectomy for 5 hours under CO(2) pneumoperitoneum without any problem. After resection of prostate, it was stopped following deflation. Thirty minutes later, peumoperitoneum was re-induced to continue the operation. Shortly after re-insufflation, the patient revealed hemodynamic instability suggested a CO(2) embolism; severe hypotension, tachyarrythmia, hypoxemia, increased CVP, and changed end-tidal CO(2)...

BACKGROUND: For patients with ventricular tachyarrhythmias, implantable cardioverter defibrillators are a mainstay of therapy to prevent sudden death. However, ICD shocks are painful, can result in clinical depression, and do not offer complete protection against death from arrhythmia. Radiofrequency catheter ablation of ventricular tachycardia in the setting of ischemic cardiomyopathy has emerged recently as a useful adjunctive therapy to ICD. OBJECTIVES: To assess the feasibility, safety and efficacy of our initial experience in ablation of scar-related VT...
