Echocardiographic Detection of Mitral Regurgitation (MR) in Mitral Valve Prolapse (MVP)

The diagnosis of mitral valve prolapse (MVP) should depend on the presence of significant mitral regurgitation or mitral complex abnormality as far as MVP is a diseased status. Concerning the echocardiographic diagnosis, the site of prolapse is difficult to determine correctly. In this study, Doppler color flow mapping was used to detect mitral regurgitation, and to decide the site of prolapse. Our new criteria of MVP include: (1) Phonocardiographic or auscultatory findings suggestive of mitral regurgitation or mitral complex abnormality. (2) A systolic bulging or an apparent systolic ballooning of the mitral valve by two-dimensional echocardiography. (3) A mitral regurgitant signal with an acceleration flow at the site of prolapse by Doppler color flow mapping.

Objective To evaluate the localization of mitral valvular(MV)prolapse by transthoracic echocardiography(TTE),transesophageal echocardiography(TEE)and explore the interrelationship between the different subregions of MV prolapse and mitral regurgitation(MR).Methods Total of thirtythree patients with MV prolapse and more than moderate MR were included.TEE was used to further judge the location of scallop lesions and the result of both TTE and TEE were compared with the surgical findings respectively.The relationship between the different subregions of MV prolapse and MR was analyzed.Results Compared with the surgery findings,the accuracy rate of TTE and TEE in diagnosis of MV prolapse was 100％ qualitatively,80％ for TTE and 94％ for TEE in localizing the diseased region with the anterior and posterior MV,the result of TEE was significantly different from TTE(P＜0.05).MR level was related to the location of MV prolapse.Conclusions Compared with the TTE,TEE had more advantages in localizing the position of the MV prolapse.Mitral regurgitation is related to the location of MV prolapse.

The evolution of mitral valve prolapse: insights from the Framingham Heart Study

Journal of Thoracic Disease (2016)

Zhaozhuo Niu Vincent Chan Thierry Mesana Marc Ruel

Abstract: The Framingham Heart Study group has described the non-diagnostic variants may evolve into mitral valve prolapse over time. These non-diagnostic variants include minimal systolic displacement, and abnormal anterior coaptation which is measured on surface echocardiography. Computed tomography and cardiac magnetic resonance imaging are evolving and can assess the degree of mitral regurgitation (MR); imaging techniques aside, genetic and proteomic detection of mitral prolapse is also evolving. However, the genetic basis for mitral prolapse is complex and likely involves multiple genetic loci. The same is also true for work determining possible biomarkers associated with mitral prolapse. The present study may be useful in counseling patients with a family history of mitral prolapse. Registry data is therefore of paramount importance in providing unbiased insight into this common disease.

[Mitral valve prolapse: beyond mitral regurgitation, the arrhythmic risk].

Revue Médicale Suisse (2021)

Guillaume Graf Patrizio Pascale Pierre Monney

Mitral prolapse is a common condition, defined by the systolic bulging of at least one mitral leaflet into the left atrium, which is often accompanied by various degree of mitral insufficiency. While for most of the patients the prognosis is linked to the severity of the valve regurgitation and its repercussions on the left ventricle (dilation and/or dysfunction), a minority of patients present with severe ventricular arrhythmia and an increased risk of sudden cardiac death, irrespective of the severity of the mitral regurgitation. To describe this particular condition, the terms arrhythmic or malignant mitral valve prolapse have been coined. The aim of this article is to describe the clinical, electrocardiographic and morphologic characteristics, which have been associated with an increased risk of arrhythmia in patients with mitral prolapse.
