Figure 2 Echocardiographic images from a patient with acute inferior myocardial infarction and right ventricular ischemia in whom angioplasty was successful. Images at end-diastole (ED) and end-systole (ES) were obtained from the transthoracic apical four-chamber view. At baseline, there was severe right ventricular dilation with reduced left ventricular diastolic size at ED. At ES, there was right ventricular free-wall dyskinesis (arrows), intact left ventricular function, and compensatory paradoxical septal motion. One hour after angioplasty, there was a striking recovery of right ventricular free-wall contraction (arrows), resulting in marked improvement in global right ventricular performance, with a markedly reduced right ventricular size and an increased left ventricular size at end diastole. At one day, there was further improvement in right ventricular function (arrows), and at one month right ventricular size and function (arrows) were normal. RV = right ventricle; LV = left ventricle.
