Trial summary

Mitral annular disjunction (MAD) is an abnormal atrial displacement of the mitral valve leaflet hinge point. MAD is gaining clinical importance for several studies reporting its association to mitral valve prolapse (MVP), complex ventricular arrhythmias and sudden cardiac death. Read more about this study

About this study

Mitral annular disjunction (MAD) is an abnormal atrial displacement of the mitral valve leaflet hinge point. MAD is gaining clinical importance for several studies reporting its association to mitral valve prolapse (MVP), complex ventricular arrhythmias and sudden cardiac death.

On the other hand, other studies found MAD as an extremely diffuse anatomical variant of mitral valve annulus without any pathological implication.

Cardiac Magnetic Resonance is the non-invasive gold standard for myocardial characterization, with the possibility of accurate anatomical and functional evaluation associated to the evaluation of focal and interstitial fibrosis, resulting useful in the identification of arrhythmic substrate and for patients risk stratification. Additionally, Cardiac Magnetic Resonance (CMR) was found to be superior to echocardiography not only in term of tissue characterization, but also in the identification of small MAD.

Therefore, in relation to the scarcity of data about MAD prevalence and pathological potential, we set a large multicenter retrospective study aimed to evaluate prevalence of MAD in patients submitted to CMR independently by the clinical suspicion, and to evaluate the association with prolapse and arrhythmias.

Read the detailed description

Multicenter retrospective study. All cardiac MRI study obtained during the first semester of 2019 will be screened in order to identify the presence and severity of MAD, it association to other myocardial condition such as bileaflet mitral valve prolapse, miltral regurgitation, curling, and focal and interstitial fibrosis at LGE and ECV evaluation.

Finally, the association between MAD and arrhythmias will be investigated.

Study groupRoleWhat they receive
Retrospective cohortConsecutive adult patients (age ≥18 years-old), submitted to Cardiac Magnetic Resonance independently by the clinical suspicions in the first semester of 2019 (from January to June 2019) that have signed an Informed Consent authorizing data collection for future retrospective clinical research protocols. Timelapse has been chosen to avoid the impact of COVID-19 pandemic.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. the outcome will be the presence of MAD

    The main objective of the present study is to investigate the prevalence of MAD in a large population undergoing CMR independently by the clinical suspicion. Therefore, the endpoint will be the prevalence of MAD in the examined population and the outcome will be the presence of MAD.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Mitral Valve Prolapse Syndrome and Arrhythmogenic Bileaflet Mitral Prolapse, run by IRCCS San Raffaele 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 1 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 15 Jan 2026. 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?

the outcome will be the presence of MAD (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06436573, which also lists 6 linked publications.

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 15 Jan 2026.
