Key result
Transesophageal echocardiography clearly identified paraprosthetic and central leaks in 9 patients with prosthetic mitral valve dysfunction, correlating well with surgical findings.
Why the study?
Does transoesophageal echocardiography improve the detection of prosthetic mitral valve dysfunction compared to transthoracic echocardiography?
Observational (n=9)
Does transoesophageal echocardiography improve the detection of prosthetic mitral valve dysfunction compared to transthoracic echocardiography?
Transoesophageal echocardiography overcomes the acoustic masking limitations of transthoracic echocardiography to accurately detect prosthetic mitral valve dysfunction.
May aid prosthetic mitral leak detection where transthoracic imaging fails; leaves open prospective validation before practice change.
ing Doppler studies and colour flow mapping, in only six patients.Transoesophageal echo- cardiography clearly showed paraprosthetic leaks in all six patients with a mechanical prosthesis and central leaks due to leaflet dehiscence in all three patients with a bioprosthesis.These results were confirmed by cardiac catheterisation or operation or both in five patients, with two patients proceeding to surgery on the basis of transoesophageal echocardiographic findings alone.The evaluation of prosthetic mitral valve dysfunction by transthoracic echocardiography is limited by acoustic masking by the prosthesis, whereas the transoesophageal probe can be positioned directly behind the left atrium.The results of transoesophageal echocardiography of mitral prosthetic dysfunction correlate well with surgical findings."

D M Krikler (1990) conducted an observational in Prosthetic mitral valve dysfunction (n=9). Transesophageal echocardiography vs. Transthoracic echocardiography was evaluated on Detection of paraprosthetic or central leaks. Transesophageal echocardiography clearly identified paraprosthetic and central leaks in 9 patients with prosthetic mitral valve dysfunction, correlating well with surgical findings.
