2- and 3-Dimensional Echocardiographic Analysis of an Unusual Transient Apical Ballooning
چکیده انگلیسی
We report the clinical case of a 60-year-old woman who referred to our hospital for the occurrence of typical chest pain during mild effort. At admission, the electrocardiogram showed S-T segment elevation from V3 to V6, and an increase in troponin I level (11.4 ng/mL). Echocardiogram showed midapical segment akinesia with depressed ejection fraction (30%). Basal segments were hypercontractile and there was evidence of dynamic obstruction of the left ventricle with an end-systolic peak gradient of 65 mm Hg. Results of emergency coronary arteriography were normal and left ventricular angiography confirmed the midapical akinesia and hypercontractility of the basal segments. Serial 2- and 3-dimensional Doppler echocardiographic examinations were performed. Regression of left ventricular outflow tract obstruction was soon detected (day 3). Fifteen days after admission, 2- and 3-dimensional echocardiography showed a complete regression of both apical ballooning and wall-motion abnormalities with an improvement in overall systolic function. Segmental volumetric analysis allowed accurate assessment of regional volumes and ejection fraction, which were indicative for a progressive reverse remodeling. Regression of wall-motion abnormalities was expressed by a normalization in regional ejection fraction curves at 15 days.
