RESUMEN
La tormenta eléctrica postinfarto agudo de miocardio es una entidad amenazante de la vida y puede estar desencadenada por la isquemia activa secundaria a enfermedad no revascularizada. Adicionalmente la injuria miocárdica y sobre el sistema de conducción puede desencadenar la aparición de extrasístoles ventriculares, las cuales pueden participar como desencadenantes de arritmias ventriculares complejas. La adecuada identificación de las extrasístoles y otros posibles desencadenantes de la taquicardia ventricular son importantes para establecer las acciones terapéuticas que lleven a un adecuado control de la tormenta. Se presenta un caso de un paciente con tormenta arrítmica desencadenada por extrasístole ventricular frecuente con acoplamiento corto, la cual presentaba fenómeno de R en T, y era refractaria a manejo farmacológico, por lo que fue tratada exitosamente con ablación con catéter de radiofrecuencia.
The electric storm after acute myocardial infarction is a life-threatening entity which can be triggered by ischemia secondary to active coronary artery disease; however, myocardial and conduction system injury may trigger the onset of ventricular premature beats, which can be involved as triggers of complex ventricular arrhythmias. The proper identification of these, and other potential triggers of ventricular tachycardia, it is important to establish the correct treatment leading to proper control of the storm. A case of a patient with arrhythmic storm triggered by frequent ventricular extrasystoles with short coupling is presented. It showed R on T phenomenon, and was refractory to pharmacological management, which was successfully treated with radiofrequency catheter ablation.

La tetralogía de Fallot es la enfermedad cardiaca congénita cianótica más común y requiere una corrección quirúrgica temprana. En la actualidad son cada vez más las mujeres que alcanzan la edad fértil posterior a la corrección quirúrgica de esta entidad, tolerando durante la adolescencia y la vida adulta las secuelas de este procedimiento. Los reportes de casos recientes evidencian que la cardiopatía mayor corregida no es una contraindicación para el embarazo. A continuación se describe el caso de una paciente con antecedente de corrección quirúrgica de tetralogía de Fallot e insuficiencia pulmonar severa secundaria a esta, quien llevó su embarazo a término sin complicaciones.
Tetralogy of Fallot is the most frequent cyanotic congenital pathology and requires an early surgical correction. Nowadays, more women reach childbearing age after surgical repair of this pathology, thus tolerating the after-effects of this procedure during adolescence and adulthood. Recent case reports show that a corrected mayor congenital heart disease does not preclude pregnancy. The following case report describes a patient with previous surgical correction of Tetralogy of Fallot and severe pulmonary regurgitation who carried her pregnancy to term without complications.

La pericarditis constrictiva es una entidad clínica que en ocasiones puede representar un reto diagnóstico. Teniendo en cuenta que la presentación clínica es usualmente la de una falla cardiaca derecha, es necesario hacer diagnóstico diferencial con otras entidades que puedan causar un cuadro clínico similar. El diagnóstico adecuado de la pericarditis constrictiva implica alta sospecha clínica e interpretación acertada de las ayudas diagnósticas. El objetivo de este artículo es abordar el diagnóstico hemodinámico de esta entidad describiendo los parámetros convencionales y aquellos afectados por la dinámica respiratoria, que cuentan con mayor sensibilidad y especificidad para este diagnóstico.
Constrictive pericarditis is a clinical entity that can be sometimes a diagnostic challenge. Given that the clinical presentation is usually that of a right heart failure, it is necessary to make a differential diagnosis with other entities that can cause a similar clinical picture. Proper diagnosis of constrictive pericarditis implies a high clinical suspicion with a correct interpretation of diagnostic aids. The aim of this article is to approach the hemodynamic diagnosis of this entity describing the conventional parameters and those affected by respiratory dynamics, which have higher sensitivity and specificity for this diagnosis.

Very late stent thrombosis is a rare and not-well-understood complication after bare metal stent implantation. It usually presents as an ST elevation acute coronary syndrome and it is associated with high rates of morbidity and mortality. Pathophysiologic mechanisms are not well defined; nevertheless, recent studies have proposed a neoatherosclerotic process as the triggering mechanism. We present the case of a patient with bare metal very late stent thrombosis 12 years after implantation.
RESUMEN
Carcinoid crisis is an infrequent and little-described complication of neuroendocrine tumors that can be life threatening. It may develop during induction of anesthesia, intraoperatively, during tumor manipulation and arterial embolization, or even spontaneously. The massive release of neuroendocrine substances can lead to potentially fatal complications. Somatostatin analogs inhibit the release of these substances and are the mainstay of treatment. The following case report describes a patient with reversible acute right-sided heart failure posterior to hepatic artery embolization.
RESUMEN
The prosthetic and orthotic field is in constant flux, with newer technology and materials being incorporated into everyday practice. Research into the field is increasing as interest in restoring or simulating lost human function becomes more of a reality with advances in computer and microprocessor technology. This article explores the world of braces and artificial limbs, and reviews the inherent challenges encountered during rehabilitation of patients who have these specific orthotic/prosthetic needs. The authors provide quick-reference tables and highlight critical information needed to manage patients. It examines newer technology being developed and gauges how close the field really is to the era of Steve Austin, television's Six-Million Dollar Man.
