Pannus-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...
متن کاملPerivalvular pannus and valve thrombosis: two concurrent mechanisms of mechanical valve prosthesis dysfunction.
A 78-year-old woman was admitted to our institution with progressive dyspnea. She had previously been diagnosed with rheumatic heart disease and had undergone cardiac surgery for mechanical mitral valve replacement ten years previously. Transesophageal echocardiography revealed blockage of the mechanical prosthesis and the patient was scheduled for surgery, in which a thrombus was removed from ...
متن کاملSixty-Four-Section Cardiac Computed Tomography in Mechanical Prosthetic Heart Valve Dysfunction: Thrombus or Pannus.
BACKGROUND Distinguishing pannus and thrombus in patients with prosthetic valve dysfunction is essential for the selection of proper treatment. We have investigated the utility of 64-slice multidetector computed tomography (MDCT) in distinguishing between pannus and thrombus, the latter amenable to thrombolysis. METHODS AND RESULTS Sixty-two (23 men, mean age 44±14 years) patients with suspec...
متن کاملA mass obstructing mechanical prosthetic heart valve: thrombus or pannus?
Mahajan K, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-219573 Description Mechanical prosthetic valve obstruction carries a significant morbidity and mortality, if not treated urgently. Most notable causes of an acquired obstruction include thrombosis and pannus formation. It is critically important to exclude isolated pannus, since thrombolysis is an effective and rapid treatment option in ...
متن کاملRecurrent pannus formation causing prosthetic aortic valve dysfunction: Is excision without valve re-replacement applicable?
Prosthetic valve dysfunction at aortic position is commonly caused by pannus formation. The exact etiology is not known. It arises from ventricular aspect of the prosthesis encroaching its leaflets causing stenosis or it may remain localized causing left ventricular outflow tract obstruction without affecting valve function.The difference in location entails different approaches in management. ...
