Heart valve tissue engineering: how far is the bedside from the bench?

2015

Heart disease, including valve pathologies, is the leading cause of death worldwide. Despite the progress made thanks to improving transplantation techniques, a perfect valve substitute has not yet been developed: once a diseased valve is replaced with current technologies, the newly implanted valve still needs to be changed some time in the future. This situation is particularly dramatic in the case of children and young adults, because of the necessity of valve growth during the patient's life. Our review focuses on the current status of heart valve (HV) therapy and the challenges that must be solved in the development of new approaches based on tissue engineering. Scientists and physicia…

Impact of systematic whole-body 18F-fluorodeoxyglucose PET/CT on the management of patients suspected of infective endocarditis: the prospective mult…

2021

AbstractBackgroundDiagnostic and patients’ management modifications induced by whole-body 18F-FDG-PET/CT had not been evaluated so far in prosthetic valve (PV) or native valve (NV) infective endocarditis (IE)-suspected patients.MethodsIn sum, 140 consecutive patients in 8 tertiary care hospitals underwent 18F-FDG-PET/CT. ESC-2015-modified Duke criteria and patients’ management plan were established jointly by 2 experts before 18F-FDG-PET/CT. The same experts reestablished Duke classification and patients’ management plan immediately after qualitative interpretation of 18F-FDG-PET/CT. A 6-month final Duke classification was established.ResultsAmong the 70 PV and 70 NV patients, 34 and 46 wer…

Improved Assessment of Pathological Regurgitation in Patients with Prosthetic Heart Valves by Multiplane Transesophageal Echocardiography

1997

The aim of this study was to evaluate the diagnostic increment of individually optimized axes in the assessment of pathological prosthetic valve regurgitation. Forty-two patients with pathologically regurgitant prostheses in the aortic (n = 21), mitral (n = 15), and tricuspid (n = 6) positions were examined by multiplane transesophageal echocardiography. The investigation was performed utilizing the transverse axis first, the longitudinal axis second, and the intermediate axes afterwards. The presence of regurgitation, the differentiation between trans- and perivalvular origin, and the localization of perivalvular leakages at the sewing ring were evaluated. Findings in the biplane and inter…

T-shaped Transseptal Approach for Mitral Valve Surgery.

2020

AbstractWe present a T-shaped transseptal approach for mitral valve surgery that makes adequate exposure possible under challenging anatomic and surgical circumstances, hence eliminating the need for forceful retraction on potentially fragile tissues. Particularly suited for patients with complex mitral pathology, it also facilitates juxta-annular transseptal right atrial anchoring, especially in cases of endocarditic anterior mitral annular destruction.

18F-FDG PET/CT in cardiovascular infection and inflammation.

2021

The diagnosis of cardiovascular infection and inflammation by [18F]FDG PET/CT in Nuclear Cardiology is of growing interest, because with respect to echocardiography this technique has improved the certainty in the diagnosis of infective endocarditis in patients with prosthetic valves, the increasing number of patients with implantable cardiac devices because of the progressive ageing of the population, as well as in patients with suspected large vessel vasculitis. All are serious clinical situations which require correct diagnosis and appropriate treatment as soon as possible, because they can cause severe complications, high mortality and also increased health care costs. We review the use…
