Summary: This study found that left atrial enlargement (LAE) in athletes is primarily associated with accumulated lifetime training thousand hours (LTH) rather than other clinical parameters, especially with less impact at higher levels of LTH. A lifetime training exceeding 3600 hours increases the likelihood of LAE in athletes. Further research should explore the insights and implications of these findings.

Summary: The left atrium plays a crucial role in maintaining normal cardiac function and is involved in many cardiac diseases. Therefore, studying the left atrium has become a priority for imaging techniques. The use of multimodality is critical, especially in diseases like atrial fibrillation or left atrial appendage closure. Understanding the usefulness of different imaging techniques for studying the left atrium is crucial for choosing the appropriate treatment.

Summary: In traditional cardiovascular medicine, the focus on the left ventricle has overshadowed the importance of the left atrium. Recent advances have shown that the left atrium plays a crucial role in various cardiovascular diseases, impacting symptoms, prognosis, and potential therapeutic targets.

Summary: This study aimed to detect atrial disease in CrS patients through analyzing atrial size and function. The results showed that patients with AF had larger atrial volume and worse atrial function, with an independent association between detection of AF and atrial volume, LAEF, and strain.

Summary: This study found that left atrial function plays an important role in the absence of atrial fibrillation (AF) in patients with left atrial dimension greater than or equal to 50 mm, and the late diastolic component of left atrial strain rate is the only independent variable associated with AF.

Summary: This case report presents a 32-year-old woman with a giant left main coronary artery to right atrium fistula accompanied by endocarditis. The diagnosis of coronary artery fistula was made using transthoracic echocardiography and subsequently confirmed by cardiac computerized tomographic and coronary angiography. The patient received 6 weeks of antibiotic treatment for infective endocarditis before undergoing successful surgical repair. The patient remains well after 18 months of follow-up.

Summary: This study explores the exercise behavior of the normal left atrium in response to graded effort by quantifying its volumetric changes. It found that low-level exercise decreases LA volume and increases ejection fraction, but these changes offset each other volumetrically. The major source of increased cardiac output with exercise is heart rate, while LA conduit fraction plays a key role in augmenting LV stroke volume.

Summary: This study investigated cardiac function, particularly the left atrium (LA), in patients with Marfan syndrome (MFS). The results showed increased LA size and secretory activity in MFS patients, despite normal left ventricular function. This finding was more pronounced in MFS patients with prior aortic surgery. Right ventricular function and right atrial size were increased only in MFS patients who had undergone aortic surgery.

Summary: In this case, the patient underwent surgery for a left atrial space-occupying lesion, with TEE playing a more crucial role in determining and differentiating the nature of cardiac space-occupying lesions.

Summary: The study compared the cardiac function of elite swimmers, water polo players, and artistic swimmers. Male swimmers showed volume-based functional adaptations distinct from the mixed volume-pressure adaptations of water polo players. Female swimmers and water polo players did not show sport-specific differences like males, but had greater volume-based adaptations compared to artistic swimmers.

Summary: This study describes the utilization of both two-dimensional (2D) and three-dimensional (3D) transesophageal echocardiography (TEE) in successfully performing transcatheter mitral valve (MV) in patients with thrombus in left atrial appendage (LAA) and/or left atrium (LA) body, which is considered a contraindication for the procedure. The procedure was successful in all patients with improvement of symptoms and no complications over a mean follow-up of 21 months.

Summary: The study investigated the relationship between arterial stiffness and left ventricular diastolic function in endurance-trained athletes. It found that lower arterial stiffness was associated with higher left ventricular diastolic function in these athletes.

Summary: This study compared left ventricular (LV) hypertrophy in early adolescent athletes and hypertrophic cardiomyopathy (HCM) genotype positive patients. The results showed that LV hypertrophy was found in a similar proportion in both groups, but only HCM genotype positive patients showed progression of hypertrophy. The study also identified a potential grey zone of LV hypertrophy with septum thickness Z-scores ranging from 2.0 to 3.3. LV volumes remained larger in athletes. These findings can help clinicians distinguish physiological LV hypertrophy from early HCM.

Summary: The study investigated the influence of left ventricular geometry on left atrium (LA) volume and phasic function in patients with obstructive sleep apnea syndrome (OSAS) using a multimodal echocardiographic approach. Results showed that concentric hypertrophy (CH) had the most notable negative effect on the maximum volume and phasic function of the LA.
