A chest X-ray on admission revealed significant cardiomegaly with pulmonary congestion (Figure 1(a)). A 12-lead electrocardiogram (ECG) revealed sinus tachycardia with biventricular pacing, which was unchanged compared to the previous findings (Figure 1(b)).
A transthoracic echocardiogram on admission revealed severe left ventricular dysfunction with marked dilatation of the chambers and severe functional mitral regurgitation.
