Three-dimensional echocardiography can overcome the obstacle of the thebesian valve.
A 77-year-old woman presented with pulmonary edema 2 weeks after experiencing an acute inferior ST-segment– elevation myocardial infarction treated successfully with primary coronary angioplasty with bare metal stent implantation in the right coronary artery. On admission, she experienced marked dyspnea, and on physical examination, she had tachy-pnea, her peripheral pulse was irregular with an...
متن کاملIntra-cardiac echocardiography in alcohol septal ablation: a prospective comparative study against trans-thoracic echocardiography
Alcohol septal ablation (ASA) in hypertrophic obstructive cardiomyopathy reduces left ventricular outflow tract gradients. A third of patients do not respond; inaccurate localisation of the iatrogenic infarct can be responsible. Transthoracic echocardiography (TTE) using myocardial contrast can be difficult in the laboratory environment. Intra-cardiac echocardiography (ICE) provides high-qualit...
متن کاملThe effect of time and of vasoactive drugs on capillary leakage induced during myocardial contrast echocardiography.
BACKGROUND Premature ventricular contractions (PVC), capillary leakage, and petechial hemorrhage can occur during myocardial contrast echocardiography (MCE). The effects occur as a result of the interaction of contrast agent microbubbles and the ultrasound, but the detailed etiology of the effects is not yet clear. This study tested the hypothesis that the capillary leakage results from a physi...
متن کاملContrast Echocardiography for Diagnosis of Apical Hypertrophic Cardiomyopathy
Most patients with hypertrophic cardiomyopathy (HCM) have asymmetric septal hypertrophy; and among them, 25% present dynamic left ventricular outflow tract obstruction. Apical HCM is unusual. Echocardiography has been the first imaging method for patients with suspected HCM, but its shortcomings in evaluating the apex are well known. We present a 56-year-old woman with a history of left hemitho...
متن کاملCardiac MR imaging of nonischemic cardiomyopathies: imaging protocols and spectra of appearances.
Recent technologic advances in cardiac magnetic resonance (MR) imaging have resulted in images with high spatial and temporal resolution and excellent myocardial tissue characterization. Cardiac MR is a valuable imaging technique for detection and assessment of the morphology and functional characteristics of the nonischemic cardiomyopathy. It has gained acceptance as a standalone imaging modal...
