RESUMO

Objective: To describe the initial experience of cardiac contractility modulation (CCM) implantation in Latin America. Method: We present the first two cases in Latin America of patients with heart failure with reduced left ventricular ejection fraction (LVEF) not candidates for cardiac resynchronization therapy in whom a CCM device was implanted. Results. Results: In both patients we described improvement of the 6-minute walk test, functional class according to the NYHA and LVEF. Conclusions: The modulation of cardiac contractility is currently a treatment option for patients with heart failure in functional class III-IV, with LVEF 25-45%, and a QRS < 130 ms who are not candidates for cardiac resynchronization therapy.

RESUMO

Remote monitoring is beneficial for the management of patients with cardiovascular implantable electronic devices by impacting morbidity and mortality. With increasing numbers of patients using remote monitoring, keeping up with higher volume of remote monitoring transmissions creates challenges for device clinic staff. This international multidisciplinary document is intended to guide cardiac electrophysiologists, allied professionals, and hospital administrators in managing remote monitoring clinics. This includes guidance for remote monitoring clinic staffing, appropriate clinic workflows, patient education, and alert management. This expert consensus statement also addresses other topics such as communication of transmission results, use of third-party resources, manufacturer responsibilities, and programming concerns. The goal is to provide evidence-based recommendations impacting all aspects of remote monitoring services. Gaps in current knowledge and guidance for future research directions are also identified.

RESUMO

Background: Documenting the patterns of oral anticoagulation therapy (OAT) is essential to prevent thromboembolic complications of nonvalvular atrial fibrillation (NVAF). Objective: To report the patterns of OAT according to age and thromboembolic risk in patients included in CARMEN-AF, a nationwide registry of NVAF in Mexico, an upper middle-income country. Material and methods: There were 1,423 consecutive patients ≥18 years old and with at least one thromboembolic risk factor enrolled in the CARMEN-AF Registry at their regular clinical visit during a three-year period. They were analyzed according to 1) age, 2) AF type, and 3) CHA2DS2-VASc score. Results: Overall, 16.4% of patients did not receive antithrombotic treatment, 19.4% received antiplatelet drugs (APD), 29.2% vitamin K antagonists (VKA), and 34.6% direct oral anticoagulants (DOAC). With increasing age, the proportion of subjects treated with VKA decreased significantly from 36.2% in subjects <65 years to 22.5% in those ≥75 years old (P <0.0001). Concomitantly, an increase in both APD and no antithrombotic treatment was observed with increasing age. DOAC were prescribed equally among all age groups (34.2% in <65, 36.0% in 65-74, and 33.9% in ≥75). According to the type of AF, VKA use was more common in patients with permanent AF (32.7%). A lower use of DOAC was observed in high thromboembolic risk subjects (33.6% in CHA2DS2-VASc ≥2) compared with the moderate risk group (41% in CHA2DS2-VASc = 1). Conclusions: VKA use for NVAF in Mexico decreased in relation to increasing age. The proportion of DOAC therapy was the same in all age groups. Nevertheless, elderly patients with high thromboembolic risk received a suboptimal thromboprophylaxis. These data could help to improve gaps in the implementation of global guidelines. Clinical trial registration: http://www.clinicaltrials.gov. Unique identifier: NCT02334852. Highlights: CARMEN-AF is a nationwide multi-centric registry seeking to bridge the data gap on anticoagulation therapy for NVAF in Mexico.Elderly patients are more prone to receive suboptimal OAT for NVAF.DOAC were less frequently used in high thromboembolic risk patients (CHA2DS2-VASc ≥2).

RESUMO

Abstract Atrial fibrillation (AF) is a frequent arrhythmia; its prevalence is near 2% in the general population; in Mexico, more than one-half million people are affected. AF needs to be considered as a public health problem. Because AF is an independent risk factor associated with mortality, due to embolic events, heart failure, or sudden death; early diagnosis is of utmost importance. In unstable patients with a recent onset of AF, electrical cardioversion should be practiced. In stable patients, once thromboembolic measures have been taken, it is necessary to assess whether it is reasonable to administer an antiarrhythmic drug to restore sinus rhythm or performed electrical cardioversion. For recidivating cases of paroxysmal and persistent presentation, the most effective strategy is performed pulmonary vein isolation with either radiofrequency or cryoballoon energy. Permanent AF is that in which recovery of sinus rhythm is not possible, the distinguishing feature of this phase is the uncontrollable variability of the ventricular frequency and could be treated pharmacologically with atrioventricular (AV) nodal blockers or with a VVIR pacemaker plus AV nodal ablation. The presence of AF has long been associated with the development of cerebral and systemic (pulmonary, limb, coronary, renal, and visceral) embolism. The prevention of embolisms in “valvular” AF should perform with Vitamin K antagonists (VKA). For patients with AF not associated with mitral stenosis or a mechanical valve prosthesis, a choice can be made between anticoagulant drugs, VKA, or direct oral anticoagulants. Antiplatelet agents have the weakest effect in preventing embolism.


Resumen La fibrilación auricular (FA) es una arritmia frecuente; su prevalencia es cercana al 2% en la población general, en México se ven afectados más de medio millón de personas por eso debe considerarse como un problema de salud pública. Debido a que la FA es un factor de riesgo independiente asociado a mortalidad, por eventos embólicos, insuficiencia cardíaca o muerte súbita, la identificación y diagnóstico temprano es de suma importancia. En el inicio reciente de FA en pacientes inestables, se debe practicar la cardioversión eléctrica. En pacientes estables, una vez que se han tomado medidas tromboembólicas, es necesario evaluar si es razonable administrar un medicamento antiarrítmico para restaurar el ritmo sinusal o realizar una cardioversión eléctrica. Para los casos que recidivan, ya sea paroxística o persistente, la estrategia más efectiva es realizar el aislamiento de la venas pulmonares con radiofrecuencia o crioablación con balón. La FA permanente es aquella en la que no es posible la recuperación del ritmo sinusal, la característica distintiva de esta fase de la FA es la variabilidad incontrolable de la frecuencia ventricular. Puede tratarse farmacológicamente con bloqueadores nodales AV o con un marcapasos VVIR mas ablación del nodo AV. La presencia de FA se ha asociado durante mucho tiempo con el desarrollo de embolia cerebral y sistémica (pulmonar, de extremidades, coronaria, renal y visceral). La prevención de embolias en la FA “valvular” debe realizarse con antagonistas de la vitamina K (AVK). Para los pacientes con FA no asociados con estenosis mitral o una prótesis valvular mecánica, se puede elegir entre medicamentos anticoagulantes, AVK o anticoagulantes orales directos (DOAC). Los agentes antiplaquetarios tienen el efecto más débil para prevenir la embolia.

RESUMO

Resumen ANTECEDENTES: Las arritmias cardiacas son complicaciones frecuentes durante el embarazo, la mayor parte son benignas y no requieren tratamiento complejo. Las taquicardias ventriculares idiopáticas suelen ser hemodinámicamente estables y se asocian con buen pronóstico. CASO CLÍNICO: Paciente de 22 años, con embarazo de 23 semanas, que inició con mareo y palpitaciones, por lo que acudió al servicio de Urgencias. El electrocardiograma de 12 derivaciones mostró una taquicardia de QRS amplio, con latidos de fusión y disociación auriculoventricular; el ecocardiograma no reportó alteraciones. El diagnóstico definitivo fue taquicardia ventricular fascicular posterior idiopática. El tratamiento inicial consistió en verapamil y amiodarona por 48 horas; sin embargo, persistió la taquicardia, por lo que se decidió realizar una cardioversión eléctrica con 200 Joules, con lo que se obtuvo una reacción satisfactoria. La paciente permaneció asintomática hasta la semana 31 del embarazo, cuando inició nuevamente con palpitaciones; se documentó la misma taquicardia, por lo que se decidió realizar un nuevo procedimiento de cardioversión eléctrica con 200 Joules, que resultó efectiva y sin complicaciones adicionales para la paciente. CONCLUSIONES: La incidencia de taquicardia ventricular idiopática durante el embarazo es relativamente baja. La cardioversión eléctrica es una opción efectiva en pacientes embarazadas con resistencia al tratamiento farmacológico o inestabilidad hemodinámica.


Abstract BACKGROUND: Cardiac arrhythmias are frequent complications in pregnancy, the most of them are benign and don't need specific treatment. Idiopathic ventricular tachycardia usually is hemodynamically stable and associate with a good prognosis. CLINICAL CASE: A 22-year-old woman with a current pregnancy of 23.4 weeks of gestation that began with dizziness and palpitations, she went to the emergency department, a 12-lead electrocardiogram showed a wide QRS tachycardia with fusion beats and atrioventricular dissociation, the echocardiogram was reported normal. Posterior fascicular ventricular idiopathic tachycardia was concluded. Initially, Verapamil and Amiodarone were administered for 48 hours, with tachycardia persisting, so it was decided to perform electrical cardioversion with 200 Joules that was effective. She remained asymptomatic until the 31st week of gestation where she started again with palpitations, the same tachycardia was documented and it was decided to perform again electrical cardioversion with 200 joules, being effective and without complications. CONCLUSIONS: Idiopathic ventricular tachycardia occurs with low frequency in pregnancy. When pharmacological therapy is not effective or there is hemodynamic instability, electrical cardioversion is a viable option in the pregnant patient.

RESUMO

Informamos el caso de una paciente de 21 años de edad con displasia arritmogénica del ventrículo derecho (DAVD), por su baja frecuencia en general, se manifestó por episodios de taquicardia con QRS mayor de 0.12 segundos de duración y disfunción aislada del ventrículo derecho. Había sido tratada con amiodarona con recurrencia de los episodios de taquicardia. El electrocardiograma de superficie durante la taquicardia mostró imagen de bloqueo de rama izquierda con un aQRS a + 115o lo que sugirió su origen en el ventrículo derecho, por lo que consideramos que se tratara de una displasia arritmogénica. El estudio ecocardiográfico y la cardioangiografía mostraron las alteraciones características en la anatomía del tracto de salida del ventrículo derecho. La gammagrafía miocárdica no mostró alteraciones de la perfusión. La biopsia endomiocárdica mostró fibrosis perivascular. Fue llevada a un estudio electrofisiológico. La estimulación en el tracto de salida del ventrículo derecho se desencadenaron dos tipos de taquicardia ventricular, una de ellas concordante con la taquicardia clínica. Fue tratada con sotalol y ha estado libre de episodios de taquicardia ventricular en 18 meses del seguimiento. Consideramos que esta entidad debe de ser sospechada en los casos de taquicardia ventricular y alteraciones morfológicas y funcionales del ventrículo derecho de forma sistemática, así mismo en aquellos pacientes con arritmias ventriculares originadas en el ventrículo derecho.
