COMPARATIVE STUDY

BACKGROUND: Aortic valve area (AVA) estimation in patients with aortic stenosis may be obtained using several methods. This study was undertaken to verify the cardiovascular magnetic resonance (CMR) planimetry of aortic stenosis by comparing the findings with invasive catheterization, transthoracic (TTE) as well as tranesophageal echocardiography (TEE) and anatomic CMR examination of autopsy specimens. METHODS: Our study was performed in eight patients with aortic valve stenosis...

PURPOSE: Tranesophageal echocardiography or direct sampling of arterial and/or right atrial blood with histological evaluation are invasive techniques used to evaluate embolic material entering the heart during total knee arthroplasty (TKA). The aim of this study was to develop a non-invasive method of detecting and quantifying the embolic matter using transthoracic echocardiography and to apply this method to compare the incidence and severity of embolism between computer-navigated (N) and conventional (C) TKA done under tourniquet...

We report a case of a 63-year-old woman who presented with infective endocarditis and developed a pseudoaneurysm (PA) of the left ventricle presumably as a result of an embolic infarct. The diagnosis was made by typical features of PA on tranesophageal echocardiography and color Doppler studies. In addition, three-dimensional transesophageal echocardiography showed the narrow neck of the PA. Findings were confirmed at surgery and she was discharged after successful repair.

We presented a very rare case of the fistula to coronary artery during staphylococcal aortic valve endocarditis in a young man. The tranesophageal echocardiography detected vegetation on aortic valve leaflets and large regurgitatin. During transesophageal echocardiography the peri-anular multi-chamber abscess formation and fistulous communication to circumflex coronary artery was detected.

This report describes a 28-year-old pregnant woman with mitral valve prolapse and sudden cardiac death due to a ventricular fibrillation who underwent an ICD implantation guided by tranesophageal echocardiography.

BACKGROUND: To date there is no direct comparison of transesophageal and transthoracic Doppler tissue data in patients with cardiac malposition. We compared data acquired from both methods in an animal model. METHOD: We studied 10 15-kg Yorkshire pigs during incremental atrial pacing to modify myocardial responses. Peak isovolumic velocity (IVV) and isovolumic acceleration (IVA) during isovolumic contraction, ejection (S wave), and diastolic velocities (early passive and active filling, E and A wave, respectively) were measured...
