Prosthetic Valve Dysfunction
Approximately 85,000 valve substitutes are implanted in the United States and 275,000 worldwide each year, of which approximately half are mechanical valves and half are bioprosthetic valves. Despite the marked improvements in prosthetic valve design and surgical procedures over the past decades, valve replacement is not a panacea for the patient. Instead, native valve disease is traded for pro...
متن کاملCardiac imaging of prosthetic valve dysfunction by transesophageal echocardiography
Prosthetic heart valve (PHV) replacement replaces a heart disease with another one. There is no ideal prosthetic heart valve. All of the prosthetic heart valves need to be followed by caution. PHV diseases (PHVD) includes a group of pathologic processes like prosthetic valve obstruction, thromboembolism and regurgitation. Correct diagnosis and treatment of these pathologic situations will decre...
متن کاملImaging of prosthetic heart valve dysfunction: complementary diagnostic value of TEE and MDCT?
P R O S T H E T I C HEART VALVES ARE INCREASINGLY IMPLANTED WORLDWIDE TO REPLACE ISEASED NATIVE V A L V E S . Prosthetic heart valve (PHV) dysfunction is rare but potentially ife-threatening. In clinical practice, transthoracic echocardiography and transesophageal echocardiogaphy, and fluoroscopy for mechanical valves, are the routine imaging modalities to evaluate suspected HV dysfunction (1)....
متن کاملProsthetic heart valve.
A 55-year-old invasive/clinical cardiologist worked full time, exercised regularly, and was asymptomatic. Two weeks previously, he had new onset of angina on exertion. Echocardiography/Doppler and cardiac catheterization confirmed the clinical assessment of severe aortic stenosis with a valve area of 0.5 cm/m. The aortic valve was tricuspid; left ventricular ejection fraction was 0.60. Coronary...
متن کاملPannus-related prosthetic valve dysfunction. Case report
Pannus-related prosthetic valve dysfunction, a complication of mechanical prosthetic valve replacement, is rare, with a slowly progressive evolution, but it can be acute, severe, requiring surgical reintervention. We present the case of a patient with a mechanical single disc aortic prosthesis, with moderate prosthesis-patient mismatch, minor pannus found on previous ultrasound examinations, wh...
