Overview of Mitral Valve Prolapse (MVP)
Mitral valve prolapse (MVP) is a valvular heart disease characterized by the displacement of the mitral valve leaflet into the left atrium. It has familial clustering and can be X-linked.
Definition and Characteristics
Mitral valve prolapse (MVP) is a valvular heart disease where an abnormally thickened mitral valve leaflet displaces into the left atrium during systole, typical in myxomatous degeneration. Different types of MVP exist, such as classic and nonclassic, with severe cases leading to complications like mitral regurgitation. It is also known to have familial clustering and potential X-linked inheritance.
Familial Clustering of MVP
Mitral valve prolapse (MVP) often demonstrates familial clustering, with potential X-linked inheritance patterns observed in certain cases.
Barlow and Bosman’s Observation
Barlow and Bosman were among the first to report familial forms of late-systolic murmur and click, indicating a potential hereditary factor in the development of mitral valve dysfunction, highlighting the familial clustering of this condition.
Monteleone et al.’s Findings
In a study by Monteleone et al., a familial clustering of mitral valve prolapse (MVP) was noted in a small family, indicating a potential X-linked mode of inheritance in MVP cases within the family.
Mitral valve prolapse (MVP) is a common disorder affecting up to 2-3% of the general population. It is known to have familial clustering and potential X-linked inheritance patterns, with increased prevalence associated with a higher risk of complications such as ventricular arrhythmias and sudden cardiac death (SCD).
