Summary
Normal reference values for Mitral annular plane systolic excursion (MAPSE) were established using echocardiography. These values, which vary by age and sex, aid in assessing left ventricular systolic function, especially with poor image quality.
Area of Science:
- Cardiology
- Echocardiography
- Cardiac Physiology
Background:
- Mitral annular plane systolic excursion (MAPSE) is a valuable index for assessing left ventricular (LV) systolic function.
- Its clinical utility is limited by a lack of established normal reference values.
Purpose of the Study:
- To establish normal reference ranges for MAPSE using M-mode and 2D speckle tracking echocardiography (2D-STE).
- To identify determinants of MAPSE in a healthy population.
Main Methods:
- A multicentre, prospective, cross-sectional study of 1952 healthy participants (aged 18-80 years).
- MAPSE was measured using M-mode echocardiography and 2D-STE.
- Multiple linear regression analysis was used to explore determinants of MAPSE.
Main Results:
- Normal age- and sex-specific reference values for MAPSE were established for both M-mode and 2D-STE.
- Women exhibited higher MAPSE than men, and MAPSE decreased with increasing age.
- MAPSE by 2D-STE showed stronger correlation with global longitudinal strain compared to M-mode MAPSE.
Conclusions:
- Established normal MAPSE reference values provide a basis for clinical assessment of LV longitudinal systolic function.
- Factors such as age, sex, blood pressure, heart rate, and LV volume influence MAPSE and should be considered.
- These reference values are particularly useful for evaluating patients with suboptimal echocardiographic image quality.

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
