Insights
Left atrial (LA) deformation is impaired in arterial hypertension and aortic stenosis, especially with left ventricular hypertrophy (LVH). Two-dimensional strain analysis reveals significant changes in LA function in these cardiovascular conditions.
Area of Science:
- Cardiology
- Medical Imaging
- Biomedical Engineering
Context:
- Arterial hypertension (AH) and aortic stenosis (AS) are common cardiovascular conditions.
- Left ventricular hypertrophy (LVH) often accompanies AH and AS.
- Left atrial (LA) function is crucial for overall cardiac performance.
Purpose:
- To investigate left atrial (LA) deformation using two-dimensional strain (TDSD) in patients with AH, AS, and varying degrees of LVH.
- To compare LA deformation patterns in healthy individuals versus patients with these conditions.
Summary:
- LA deformation was assessed in 20 healthy subjects and 68 patients (30 with AH/mild LVH, 22 with AH/manifest LVH, 16 with AS) using TDSD.
- Abnormal LA deformation was observed in AH and AS patients, even with mild LVH.
- AS was associated with the most significant LA deformation abnormalities, particularly during the atrial accumulation phase.
Impact:
- TDSD provides a detailed analysis of atrial deformation, aiding in the understanding of cardiac pathophysiology.
- Findings highlight the impact of pressure overload on LA function in hypertensive and AS patients.
- This analysis offers new avenues for research into atrial remodeling and dysfunction.
Aim:
To study left atrial (LA) deformation in patients with arterial hypertension, aortic stenosis (AS) and left ventricular hypertrophy (LVH) of different severity.
Material And Methods:
LA deformation was studied in 20 healthy subjects and 68 patients. Of them 30 patients had AH and mild LVH, 22-AH and manifest LVH, 16 patients had AS. Standardechocardiography (EchoCG) was made and then analysed with the method of two-dimentional seroscale deformation (TDSD). Segmentory maximal deformation was estimated in 5 middle segments of left atrial walls, middle maximal deformation was determined in 4- and 2-chamber positions, global maximal deformation were evaluated in left atrial contraction and accumulation phases.
Results:
Due to pressure-induced overloading, LVH was accompanied with abnormal left atrial deformation, AH patients demonstrated decreased deformation even in mild LVH. AS was associated with most pronounced changes of left atrial deformation. Abnormal left atrial deformation in AH and AS was more significant in accumulation phase. In contraction phase, left atrial deformation deterioration occurred only in AS.
Conclusion:
Conduction of TDSD enables analysis of atrial deformation and opens wide perspectives for further investigations aimed at better understanding of changes in the atria.
