New recommendations for evaluation of prosthetic valves with echocardiography and doppler ultrasound.
Valve replacement remains common in the adult patient despite advances in valve repair. While a physical examination can alert the clinician to the presence of valve dysfunction, diagnostic methods are often needed to assess the function of the prosthesis. Echocardiography with Doppler is currently the method of choice for non-invasive evaluation of prosthetic valves. A recently published "Guid...
متن کاملEvaluation of prosthetic heart valves by transesophageal echocardiography: problems, pitfalls, and timing of echocardiography.
Transesophageal echocardiography (TEE) is especially suitable for examination of prosthetic valves because of the proximity of the esophagus to the heart and absence of interference with lungs and ribs. This article reviews normal and abnormal morphologic characteristics of prosthetic valves such as spontaneous echocontrast, microbubbles, strands, sutures, vegetations or thrombus. Doppler echoc...
متن کاملAssessment of prosthetic heart valve function by Doppler echocardiography. A decade of experience.
Since the first report of the application of Doppler echocardiography in the evaluation of prosthetic heart valves 10 years ago, dozens of studies have reaffirmed the usefulness of this technique in the noninvasive assessment of transvalvular hemodynamics. Most of these studies have established "normal values" for Doppler-determined pressure gradients and valve areas of prosthetic mitral and ao...
متن کاملThe challenge of assessing heart valve prostheses by Doppler echocardiography.
The assessment of prosthetic valve function remains challenging. Echocardiography has become the key diagnostic tool not only because of its noninvasive nature and wide availability but also because of limitations inherent in alternative diagnostic techniques. Invasive evaluation is limited particularly in mechanical valves that cannot be crossed with a catheter, and in patients with both aorti...
متن کاملContinuous Wave Doppler Echocardiographic Measurement of Prosthetic Valve Gradients
Studies correlating prosthetic valve gradients determined by continuous wave Doppler echocardiography with gradients obtained by cardiac catheterization have, to date, been limited to patients with mitral and tricuspid prostheses or have compared nonsimultaneous measurements. Simultaneous Doppler and catheter pressure gradients in 36 patients (mean age, 63+13 years) with 42 prosthetic valves (2...
