Insights
Structural heart anomalies (SHA), often linked to connective tissue dysplasia syndrome, include mitral valve prolapse and abnormal left ventricle chords. Multiple abnormal chords may indicate left ventricular non-compaction, a serious hereditary condition.
Area of Science:
- Cardiology
- Genetics
- Developmental Biology
Background:
- Structural heart anomalies (SHA) are congenital cardiovascular abnormalities.
- SHA are associated with connective tissue dysplasia syndrome (CTDS), a common autosomal-dominant disorder.
- Common SHA include mitral valve prolapse and abnormal left ventricle chords.
Purpose of the Study:
- To describe the characteristics and clinical significance of structural heart anomalies.
- To highlight the prognostic implications of specific SHA, such as abnormal left ventricle chords.
Main Methods:
- Review of existing literature on structural heart anomalies and connective tissue dysplasia syndrome.
- Analysis of clinical significance based on severity and impact on intracardial hemodynamics.
Main Results:
- Mitral valve prolapse and abnormal left ventricle chords are frequent SHA.
- The clinical impact of SHA varies with severity and hemodynamic effects.
- Multiple abnormal left ventricle chords are prognostically significant.
Conclusions:
- Structural heart anomalies are diverse congenital conditions impacting cardiovascular health.
- Abnormal left ventricle chords, particularly multiple instances, warrant attention due to potential links to serious hereditary diseases like left ventricular non-compaction.
Abstract:
Structural heart anomalies (SHA) are congenital abnormalities of cardiovascular system, characterized by various anatomical departures of heart and great vessels from normal conditions. SHA are a part of connective tissue dysplasia syndrome (CTDS), one of the most common congenital autosomal-dominant diseases in people of young and middle age. The most common SHA are a mitral valve prolapse, abnormal chords of left ventricle and their combinations. The clinical significance of these anomalies depends on a degree of severity and impact on intracardial hemodynamics, as described in the article. The most prognostically dangerous are multiple abnormal chords of left ventricle, which can be a sign of serious hereditary disease - a left ventricular non-compaction.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Anatomy of the Heart
The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.

Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...
