Abstract
No abstract available. Article truncated at 150 words. A 67 year-old woman presented with pleuritic, non-radiating chest pain of sudden onset. She was anxious, diaphoretic, and tachycardic. The chest radiograph (Figure 1A) showed decreased vascular markings in the entire right lung field (oligemic right lung field) and reduced prominence of the right pulmonary artery. A small opacity in right lower lung field was suspicious for a pulmonary infarct. A follow-up computed tomographic pulmonary angiography (CTA) showed a large embolus in right pulmonary artery and a smaller embolus in the subsegmental left pulmonary artery (Figure 1B). Twelve-lead electrocardiogram (EKG) findings were notable for a new onset right bundle branch pattern, deep S wave in lead I, with a q-wave and inverted T-wave in Lead III (Figure 1C). A 2-Dimentional echocardiogram showed a massively dilated and hypokinetic right ventricle. The CTA also revealed that the massively distended right ventricle with a deviated interventricular septum was compressing the left ventricle (Figure …
