Mitral paraprosthetic leak diagnosed by transesophageal echocardiography through nasal way
TL;DR: In this report a mitral paraprosthetic dehiscence was diagnosed using a miniaturized, 10 F, monoplane probe inserted through nasal way, and appears to be well tolerated providing an accurate and more comfortable examination.

Abstract: Paraprosthetic leaks are a postoperatively complication recurring with a frequency from 15 to 30%, and mostly in the mitral than in the aortic position. Transthoracic echocardiography can suspect prosthesis valve dysfunction, but for both diagnosis and evaluation of the paraprosthetic dysfunction severity, transesophageal study is required. In this report a mitral paraprosthetic dehiscence was diagnosed using a miniaturized, 10 F, monoplane probe inserted through nasal way. This technique, that do not require topical and general anesthesia, appears to be well tolerated providing an accurate and more comfortable examination.

TL;DR: A 73 woman with a history of replacement of heart valves (mitro-aortic replacement with biological prosthesis about a year before) was referred for surgical evaluation for a progressive worsening of fatigue and dyspnea and for low-grade fever in the evening.

Prevalence and clinical significance of incidental paraprosthetic valvar regurgitation: a prospective study using transoesophageal echocardiography.
TL;DR: Small paraprosthetic leaks are common, are related to surgical factors, are not associated with increased subclinical haemolysis, and are benign during the first year after heart valve replacement.

Diagnosis and management of complications of prosthetic heart valves.
TL;DR: Prosthesis dysfunction due to thrombus may be recognized clinically by recurrence of heart failure, syncope, cardiomegaly and altered prosthetic valve sounds or new murmurs, and prompt reoperation is indicated for this potentially lethal problem.

Transesophageal echocardiographic (TEE) evaluation of prosthetic valves.
TL;DR: TEE allows assessment of prosthetic valve anatomy and function and paraprosthetic anatomy, and serves as the diagnostic imaging modality of choice for patients with suspected prosthesis dysfunction or endocarditis.

TL;DR: This new phased-array ICE device with 2-dimensional sector imaging and full Doppler capability can guide cardiac interventions without fluoroscopy, however, further studies are needed to evaluate whether it can replace fluorideoscopy.

TL;DR: It is demonstrated that it is feasible and generally safe to introduce a miniaturized transesophageal echocardiography probe transnasally in awake cardiac risk patients to monitor cardiac performance during the induction of general anesthesia.
