Degenerative Mitral Valve DiseaseNCT05836532
Long Term Results of Surgical and Percutaneous Double Orefices Mitral Repair in Patient With p2 Prolapse Causing Degenerative Mitral Regurgitation
An observational study of Degenerative Mitral Valve Disease and Mitral Regurgitation, run by Michele De Bonis at 1 site in Italy.
Trial summary
Mitral regurgitation is a pathology affecting the left atrioventricular valve that causes a volumetric and pressure overload in the left chambers due to the loss of unidirectionality normally guaranteed by the cardiac valve system. Read more about this study

About this study
Mitral regurgitation is a pathology affecting the left atrioventricular valve that causes a volumetric and pressure overload in the left chambers due to the loss of unidirectionality normally guaranteed by the cardiac valve system. The gold standard for severe mitral regurgitation is currently mitral valve plastic surgery.
Edge to edge, on the other hand, allows shorter CEC and aortic clamping times and does not require significant surgical experience in the field of mitral valve repair, therefore edge to edge could be an excellent strategy in patients suffering from mitral regurgitation caused by P2 prolapse when quadrangular resection cannot be performed.
The main objective of the present study is to examine the medium to long-term outcomes (in terms of survival and plastic outcomes) of patients undergoing central edge-to-edge to treat posterior flap pathology (P2).

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2023; AzTrials last refreshed its copy on 8 Nov 2026.
