RESUMEN
Infections from coxsackie B2 viruses often cause viral myocarditis and, only rarely, multisystem organ impairment. We present the unusual case of a 42-year-old man in whom coxsackie B2 virus infection caused multiorgan infection, necessitating distal pancreatectomy, splenectomy, renal dialysis, and venoarterial extracorporeal membrane oxygenation with mechanical ventilation. In addition, the patient had a rapid-eye-movement sleep-related conduction abnormality that caused frequent sinus pauses of longer than 10 s, presumably due to myocarditis from the coxsackievirus infection. He recovered after permanent pacemaker placement and was discharged from the hospital. We discuss our aggressive supportive care and the few other reports of multiorgan impairment from coxsackieviruses.

Atypical hemolytic uremic syndrome (aHUS) is a serious hematologic disorder with high mortality if left untreated. A comprehensive literature review revealed only two cases of aHUS post-heart transplantation. In both cases the disease developed after induction of calcineurin inhibitor therapy. We report a case of immediate post-heart transplantation aHUS, manifested before the induction of, and therefore not associated with, calcineurin inhibitors.

Left ventricular (LV) function was shown to play a paramount role in the evaluation, management, and prognosis of patients with cardiac pathology. With the advent of multidetector computed tomography (MDCT), a novel tool for cardiac function assessment became available. This comes at no additional cost to the patient undergoing coronary CT angiography in terms of radiation exposure or contrast material delivery. The accuracy of LV function assessment by retrospective electrocardiographic gating intimately depends on the level of spatial and temporal resolution achievable during scanning. With the aid of today's fast-advancing technology, MDCT is now capable of acquiring data with isotropic submillimeter voxels that allow true 3-dimensional threshold-based chamber segmentation for accurate volumetric analysis. The challenge, however, continues to involve optimizing temporal resolution through various reconstruction techniques and technologic innovations. MDCT-determined global LV function variables were shown to strongly correlate with those of standard imaging methods. Regional function assessment has now become feasible with today's latest scanners. Its accuracy, however, still awaits a major breakthrough in temporal resolution to approach or possibly surpass that of echocardiography or magnetic resonance imaging.
