Accuracy of echocardiography for assessing aortic root diameter.
The normal range for aortic root diameters employing the echocardiographic continuous recording technique was determined in 159 adult subjects without aortic valve disease or hypertension. In order to evaluate the accuracy of this noninvasive technique, the aortic root diameters as measured by ultrasound before operation in 31 patients with aortic valve disease were compared with their respecti...
متن کاملLocalized Aortic Root Dissection Secondary to Contrast Agent Injection: Feasibility of Conservative Follow-up With Echocardiography
Introduction: Iatrogenic aortocoronary dissection (ACD) is a nightmare in interventional cardiology. Although ACD is rarely reported, the real-world prevalence is suspected of being higher due to unreported cases. The right coronary artery (RCA) ostium is involved in the majority of cases, and dissections are usually limited to the aortic sinus in half of the clinical presentat...
متن کاملDiagnosis of aortic root dissection by echocardiography.
ed from a previous study from our laboratory."2 widened wall with small changes in transducer angulation or instrument sensitivity. In all but one of our patients, slender valve cusps moved to the periphery of the inner lumen in systole and did not extend to the outer lumen. One patient (Case 5) showed some evidence of thickening of valve cusps and in another thin leaflets were identified, but ...
متن کاملAgreement of 3d-ssfp and echocardiography for aortic root dimensions
Background Respiratory navigated, ECG-gated, 3D-isotropic steady state free precession (3D-SSFP) is increasingly utilized in pediatric aortopathy. This is particularly true in adolescents as acoustic windows become limited. The agreement between echocardiography (ECHO) and 3D-SSFP obtained measurements could be influence by imaging plane, timing (systole versus diastole) and image quality. With...
متن کاملDysfunction of bileaflet aortic prosthesis: accuracy of echocardiography versus fluoroscopy.
OBJECTIVES The authors sought to investigate the accuracy of transthoracic echocardiography (TTE)-derived parameters in the identification of bileaflet aortic prosthesis dysfunction, compared with fluoroscopy (FL). BACKGROUND Identification of bileaflet aortic prosthesis dysfunction is challenging, because high mean pressure gradient (MPG >20 mm Hg) is not proof of prosthetic obstruction (AVP...
