To date, no pts presenting with syncope or presyncope, without documented prior clinical arrhythmias, have experienced sustained v-r at follow-up, suggesting a possible non-arrhythmic mechanism for syncope. (2) In contrast, 29% of pts expedanced inappropriate shocks, most often due to SVAs. Careful attention to device programming, or perhaps implantation of dual chamber devices with utilization of detection enhancements, may help reduce inappropriate therapy.

In our Arrhythmia Unit 25 patients (8 women, 17 men) aged (mean +/- DE) 56 +/- 10 years have undergone fulguration of the atrioventricular junction since 1986. The more frequent treated rhythm disturbance was atrial flutter or fibrillation, with uncontrolled rapid ventricular response. Absence of organic heart disease was diagnosed in 9 patients; the remainder had valvular heart disease (2), cor pulmonale (2), cardiomyopathy (7), hypertensive heart disease (2) and Wolff-Parkinson-White syndrome (3). Under general anesthesia 1.8 +/- 0.8 shocks/patients were delivered along 1.2 +/- 0.7 sessions/patient. In 23 of 25 patients (92%) complete atrioventricular block was achieved, and a pacemaker was implanted. There were no complications. The other 2 patients were referred to surgery for cryoablation of the atrioventricular junction...

The incidence of CI tended to be higher in patients who discontinued warfarin after 12 months of stenting than those continued (12.5% vs. 5.1%, p=0.143), whereas there was no significant difference in the rate of MACE (43.1% vs. 37.3%, p=0.503). Cumulative rate of major bleeding Conclusions: The prognosis of AF patients after coronary artery stenting is poor as a whole. As described in the guideline of European Society of Cardiology, Vitamin K Antagonist (VKA) is needed for the prevention of CI, and prolonged use of combined antithrombotic agents increases the risk of major bleeding.

The evidence from studies published to date show that women have a higher mean resting heart rate, a longer QT interval, a shorter QRS duration, and a lower QRS voltage than men. Women have a higher prevalence of sick sinus syndrome, inappropriate sinus tachycardia, atrioventricular nodal reentry tachycardia, idiopathic right ventricular tachycardia, and arrhythmic events in the longQT syndrome. In contrast, men have a higher prevalence of atrioventricular block, carotid sinus syndrome, atrial fibrillation, supraventricular tachycardia due to accessory pathways, Wolff-Parkinson-White syndrome, reentrant ventricular tachycardia, ventricular fibrillation and sudden death, and the Brugada syndrome. With regard to implantable devices, it has been reported that defibrillators offer similar benefits in men and women. Moreover,...

It doubles the mortality rate in affected patients and the condition is associated with a greater risk of stroke. Over the past decade, arrhythmia specialists have concentrated on determining the etiology and physiopathology of this disease. Such efforts have provided a fresh view on the onset, perpetuation and treatment of this arrhythmia. Until present, though, most patients have received traditional treatment, that is, antiarrhythmic drugs and/or electrical cardioversion. Electrical cardioversion of persistent atrial fibrillation is a very effective treatment for restoring sinus rhythm, though recurrence is common. Many recurrences are a clinical consequence of electrical remodeling in atrial tissue, with a shortening of the refractory period. One of the clinical problems we face when dealing with atrial fibrillation is to establish a classification that has prognost...

Elective minimally invasive valve replacement surgery was proposed, which the patient rejected. Angiodysplasia is a degenerative disease of the intestinal mucosa related to the aging process and one of the main causes of gastrointestinal bleeding in the elderly. Its association with aortic stenosis is well known.Manymechanisms have been considered to explain this syndrome; currently the most prominent is an acquired deficit of Type IIa vonWillebrand factor, characterized by a loss of the largest VWF multimers, although this causal relationship cannot always be demonstrated, as in this case. Von Willebrand factor is a high-molecular-weight multimeric protein secreted by endothelial cells that stimulates platelet adhesion and aggregation when there is vascular damage. These multimers are cleared by plasma proteases that are especially active in turbulent blood flow situations. In aortic stenosis, fragmentation of VWFmultimers is increased, which reduces their number ...

MATERIAL AND METHODS Biochemical markers were analyzed prospectively for 30 consecutive patients after electrical cardioversion. Concentrations of cTnI, myoglobin, creatine kinase (CK), CK-MB and the MB/CK ratio were determined in samples before cardioversion and 2, 8 and 24 h later. The shock energy ranged from 50 to 360 joules (235 106 joules) in external cardioversions and from 3 to 37 joules (15 8 joules) in internal cardioversions. RESULTS We detected abnormal concentrations of CK, myoglobin, CK-MB and MB/CK in 33% of the patients after external cardioversion. The concentrations of cTnI remained within normal limits at all times, with no elevations detected. Whereas no abnormal concentration of any biochemical ma...

Although is an autosomal dominant trait, a group of non-sarcomeric genes have been postulated as modifiers of the phenotypic heterogeneity. We prospectively recruited 168 HCM patients and 136 healthy controls from 3 referral centres. Patients and controls were clinically stable at entry in the study. Nine polymorphisms previously associated with ventricular remodeling were determined: I/D ACE, AGTR1(A1666C), CYP11B2(C344T), PGC1-α(G482S), COLIA1(G2046T), ADRB1(R389G), NOS3(G894T), RETN(-420C>G), CALM3(-34T>A). Their potential influence on prognosis, assessed by hospital admissions and their cause were recorded. The median follow-up time was 49.5 months. Allele and genotype frequencies did not differ between patients and controls. Thirty six patients (21.5%) required urgent hospitalization (18.5% for heart failure, 22.2% for atrial arrhythmias, 11.1% for ventricular arrhythmias, 29.6% ...

After RF ablation there is always a small localized endomyocardial necrosis, necessary to abolish the arrhythmia. We designed this study to determine the serum concentrations of several cardiac markers in patients who underwent RF catheter ablation. The study shows a higher frequency of increase of serum cardiac troponin I (cTnI) than of creatine kinase (CK), the CK MB isoenzyme (CK-MB), or myoglobin. A pathological value of cTnI was found in 47 of 51 patients (92%) in the ablation group. The area under the ROC curve for cTnI was 0.9375, significantly higher than for the other biochemical markers (0.86, 0.76, and 0.75 for CK-MB, myoglobin, and CK, respectively), with P <0.05. We conclude that the serum concentration of cTnI is the best biochemical marker for detecting the minor myocardial damage produced by RF ablation.

Me´todos: Identificar los centros españ oles que realizan implantes de resincronizació n solicitando un cuestionario (septiembre de 2010 a septiembre de 2011) a cada equipo. Resultados: Se identificó un total de 88 centros, de los que 85 (96,6%) cumplimentaron la hoja de recogida de datos. El nú mero de implantes de resincronizador (marcapasos o desfibriladores) fue de 2.147 (el 85,6% del total estimado de 2.518 por la European Confederation of Medical Suppliers Associations en ese periodo). El nú mero de implantes/milló n de habitantes comunicados fue 46 y el estimado, 54 (media en Europa, 131). Los implantes/recambios de resincronizador suponen el 84% y las mejoras del modo de estimulació n upgrade de dispositivos previos, un 16%. La mayor parte de los resincronizadores se implantaron en varones (70,7%), con medias de edad de 68 AE 12 años y de fracció n de eyecció n ventricular izquierda del 26,4 AE 5%. La mayoría de los pacientes (67%) estaban en clase funcional III de la New York Heart Association. El grupo de pacientes con nueva indicació n segú n la ú ltima actualizació n de guías es ya significativo, con el 17,3% entre los pacientes en clase II y el 21,6% de los pacientes con fibrilació n auricular. El 73,8% de los implantadores son electrofisió logos, seguidos por los cirujanos (21,4%). Conclusiones: Las nuevas indicaciones recomendadas se está n implantando progresivamente segú n los datos obtenidos en pacientes en clase II o fibrilació n auricular. Sin embargo, el nú mero de implantes de resincronizador en Españ a aú n está lejos de la media europea.

Aunque resulta difícil precisar su incidencia, los datos recogidos en los diferentes estudios publicados la sitúan entre el 4 y el 12% de los casos de muerte súbita 2. Han sido descritos casos de este síndrome en casi todas partes del mundo. En algunas zonas de Asia representaría la causa más frecuente de muerte súbita en adultos jóvenes sin cardiopatía estructural 3. Posiblemente la prevalencia esté infraestimada debido a la existencia de formas ocultas del síndrome.
