ABSTRACT
Coronary artery aneurysm is defined as a coronary dilation that exceeds the diameter of adjacent segments or the diameter of the patient's largest normal coronary vessel by 1.5×. It is an uncommon disease that has been diagnosed with increasing frequency since the widespread appearance of coronary angiography. The published incidence varies from 1.5% to 5%, suggesting male dominance and a predilection for the right coronary artery. Although several causes have been described, atherosclerosis accounts for ≥50% of coronary aneurysms in adults. Reported complications include thrombosis and distal embolization, rupture, and vasospasm, causing ischemia, heart failure, or arrhythmias. The natural history and prognosis remain unknown, as definitive data are scarce. Controversies persist regarding the use of medical management (antithrombotic therapy) or interventional/surgical procedures. Only some case reports or small case series are available about this condition. The Coronary Artery Aneurysm Registry (CAAR; http://www.ClinicalTrials.gov NCT02563626) is a multicenter international ambispective registry that aims to provide insights on anatomic, epidemiologic, and clinical aspects of this substantially unknown entity. In addition, the registry will assess management strategies (conservative, interventional, or surgical) and their short- and long-term results in a large cohort of patients. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov. Unique identifier: NCT02563626.

OBJECTIVE: To compare the prognosis during hospitalization and maximum follow-up of 4 years in patients with myocardial infarction complicated with cardiogenic shock. METHOD: Prospective observational study practiced in a coronary Care Unit managed by cardiologists. We included patients with myocardial infarction complicated with cardiogenic shock who received early coronary revascularization. Patients were divided into two groups: older than 75 years (group A) and lower (group B), and we compared the evolution during hospitalization and maximum follow-up of 4 years. Primary end point was mortality rate in the maximum follow-up of 4years. Secondary end point was mortality rate during hospitalization. RESULTS: Ninety-seven patients were included, 45% Group A. Patients of Group B were mostly men (81% vs. 57%; P=.014), diabetics (48% vs. 21%; P=0.006), and smokers (39.6% vs. 5%). Mortality rate during hospitalization was higher in Group A (54.5%) vs. 30.2% in Group B (P=.022). Mortality rate during follow-up (primary variable) was 73% in Group A vs. 38% in Group B (P=.007). CONCLUSIONS: Myocardial infarction complicated with cardiogenic shock in elderly patients is an entity with high mortality during hospitalization and continues to worsen during long term follow-up.

Objetivo: Comparar la evolución durante el ingreso y a largo plazo de pacientes con choque cardiogénico de origen isquémico. Método: Estudio observacional prospectivo unicéntrico llevado a cabo en la unidad coronaria de un hospital terciario manejada por cardiólogos. Se incluyen pacientes con choque cardiogénico de origen isquémico que recibieron revascularización coronaria precoz. Dividimos a los pacientes en 2 grupos: mayores de 75 anos (grupo A) y menores (grupo B), y comparamos la evolución durante el ingreso y en un seguimiento máximo de 4 años. El objetivo principal fue estimar la mortalidad a los 4 años. El objetivo secundario se definió como la mortalidad intrahospitalaria. Resultados: Incluimos a 97 pacientes, 44 del grupo A (45%). Los pacientes del grupo B eran con más frecuencia varones (81 vs. 57%, p = 0.014), diabéticos (49 vs. 21%, p: 0.006) y fumadores (39.6 vs. 4.5%, p < 0.05). La mortalidad hospitalaria fue superior en el grupo A (54.5 vs. 30.2%, p = 0.022). El objetivo principal ocurrió en 32 pacientes del grupo A frente a 20 del grupo B (73 vs. 38%, p = 0.007). Conclusión: El choque cardiogénico de origen isquémico en paciente mayores de 75 anos presenta una alta mortalidad durante la estancia hospitalaria y en el seguimiento a largo plazo.

Coronary artery fistula between a coronary artery and a cardiac chamber is a rare condition, especially when multiple fistulas communicate with the left ventricle. Herein we report a case of an elderly woman with multiple diffuse coronary artery-left ventricular fistulas diagnosed by angiography. Since the coronary artery-cardiac chamber communications were multiple and diffuse neither surgery nor transcatheter coil occlusion was considered in this case.

Las fístulas de las arterias coronarias que drenan a las cavidades cardíacas son una anomalía infrecuente, especialmente cuando son múltiples y drenan hacia el ventrículo izquierdo. Presentamos el caso de una mujer octogenaria con múltiples fístulas difusas que se originan de la coronaria izquierda y que drenan al ventrículo izquierdo. El hecho de que fuesen múltiples y difusas imposibilitó una intervención quirúrgica o percutánea como se recomienda en estos casos. (Arch Cardiol Mex 2004; 74:45-48).
