An observational study of Mitral Valve Disease, run by Michele De Bonis at 1 site in Italy.
Trial summary
Mitral regurgitation (MR) is a disease affecting the mitral valve that it causes a volumetric and pressure overload in the left chambers due to the leak of the unidirectionality normally guaranteed by the heart valve system. Read more about this study

About this study
Official title: Are the Results of Minimally Invasive Mitral Valve Repair Still Satisfactory When Looked at Very Long-term
Mitral regurgitation (MR) is a disease affecting the mitral valve that it causes a volumetric and pressure overload in the left chambers due to the leak of the unidirectionality normally guaranteed by the heart valve system.
The gold standard for severe mitral regurgitation is currently surgical mitral valve repair (PLM) using longitudinal median sternotomy to expose the heart Since the mid-1990s, the right mini-thoracotomy, ie a surgical access with cut in the 3rd or 4th intercostal space that would allow to reduce the size of the surgical site making it less traumatic and more aesthetic, addressing mainly a young target population.

Since the 2000s this method has spread more and more, expanding all over the world and spreading especially in the United States and Germany. This method has been progressively used in the treatment of the whole mitral valve surgery starting from valve repair up to prosthetic replacements.
Mitral valve repair through minimally invasive access in degenerative pathology has made it possible to obtain excellent long-term results, with low recurrence rates of regurgitation. In our center the results on the first 48 patients have been published in 2005 by Lapenna et al. Over the years this method has been adopted in thousands of patients worldwide, however the data present in the literature they stop at a follow-up of about 10 years. In 2017 De Bonis et al. of the San Raffaele Hospital have published the outcome of a particular subgroup of patients (bileaflet prolapse) treated with minimally invasive access, comparing them with as many subjects subjected to the same method of mitral repair ("edge-to-edge technique or Alfieri stitch"), obtaining superimposable long-term results (about 14 years old).
The goal of the present study is to analyze very long-lasting results in patients treated with mitral valve surgery with access in right mini-thoractotomy.

Questions about this trial
What is this clinical trial studying?
An observational study of Mitral Valve Disease, run by Michele De Bonis at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
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?
Mortality (time frame: through study completion, a minimum of 16 years). It is what the study was designed to measure, not a finding.
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.
