We report a case of a 34-year-old female with low-grade dyspnea on exertion despite markedly dilated left atrium (LA) on chest radiography which clouded our interpretation of the cause of enlarged cardiac silhouette. However, echocardiogram proved useful in demonstrating severe mitral stenosis and the giant LA.

Abstract Background Rheumatic heart disease has become rare in developed countries and physicians have grown unfamiliar with the disease and its clinical course. The mitral valve is most commonly affected leading to mitral regurgitation and/or stenosis. The chronic volume and/or pressure overload leads to atrial remodelling and enlargement, driving the development of atrial fibrillation and thromboembolic events. Case Summary A 87-year-old patient with a history of rheumatic mitral stenosis and mitral valve replacement was admitted to the neurology department for vertigo. A stroke was suspected and she underwent a transoesophageal echocardiogram which was complicated by dysphagia. Oesophageal manometry and CT revealed oesophagogastric junction outflow obstruction due to extrinsic compression by a giant left atrium. Discussion Dysphagia due to a giant left atrium is rare. Various diagnostic criteria exist and the prevalence thus depends on which criterium is used. It is mostly encountered in rheumatic mitral disease, although there are reports of non-rheumatic etiology. When the left atrium assumes giant proportions it can compress adjacent intrathoracic structures. Compression of the oesophagus can lead to dysphagia, as in our case. A transoesophageal echocardiogram in these cases is relatively contraindicated and should only be performed if there is considerable reason to believe that it may change patient management.

Background: The predominant cause of giant left atrium (GLA) is rheumatic mitral valvular disease. GLA is commonly defined echocardiographically by measuring the left atrial diameter (LAD). In the context of changing epidemiology of rheumatic heart disease (RHD) globally, and introduction of left atrial volume index (LAVI), the aetiology of GLA and utility of LAVI for defining GLA may be necessary. Methods: The prospective observational study was carried out at a dedicated tertiary care cardiac centre of a developing country to know the aetiology and clinical pattern of GLA over 8 years. GLA was defined echocardiographically as a left atrium (LA) having a diameter ≥80 mm in the left parasternal long-axis view. Follow-up was made over the telephone. Results: Thirty cases of GLA were diagnosed over 8 years from 2013 to 2021. Twenty two were due to rheumatic heart disease (RHD), 7 due to MVP, and 1 due to flail anterior mitral leaflet. Mean LAD was 92.13 ± 16.72 mm, and the mean LAVI was 288.77 ± 134.40 ml/m2. LA thrombus was present in 5 patients, 6 had spontaneous echo contrast (SEC) in LA, 2 had both LA thrombus and SEC. Mean follow-up was 0.99 ± 1.06 years. Out of 15 patients, 5 died, while 10 were alive. Mean survival was 1.8 ± 1.17 years, ranging from less than 1 year to 4 years. Conclusion: RHD continues to be the predominant cause of GLA; however, MVP is also important. The cut-off value of LAVI for defining GLA needs further study.

Giant left atrium is a condition characterized by an extreme enlargement of the left atrium with a diameter more than 80 mm and it is usually associated with long standing rheumatic mitral valve disease. We present a case of giant left atrium in a 47-year-old female patient who had a history of rheumatic heart disease, severe mitral disease, permanent atrial fibrillation and causing the compression of adjacent intra-thoracic structures. The patient underwent a successful mitral valve replacement with reduction of the enlarged sized left atrium with good outcomes.

AbstractAtrial functional mitral regurgitation is a hot research topic in the field of mitral valve disease. Atrial functional mitral regurgitation is distinctly different from ventricular functional mitral regurgitation. The surgical indications for atrial functional mitral regurgitation have not been well established because of the small amount of evidence gathered to date. Mitral annular plication with an artificial ring is an essential surgical procedure because dilatation of the mitral valve annulus is a main factor underlying this pathology. Most of these cases can be treated by mitral annuloplasty alone. However, additional procedures, such as application of artificial chordae to the anterior leaflet for pseudo-prolapse, and posterior leaflet augmentation with a pericardial patch, are required in advanced cases with a giant left atrium and extremely enlarged mitral annulus. Chronic atrial fibrillation causes enlargement of the right and left atria. This pathology is a bilateral atrioventricular valve disease (dual-valve disease). Therefore, the conventional guidelines of single-valve disease should not be applied. Although atrial functional tricuspid regurgitation is underappreciated, tricuspid annuloplasty should be considered for most patients to prevent future regurgitation. In addition to the mitral and tricuspid valve procedure, integrated surgical management, including plication of the atrium and left appendage closure, is required. This review summarizes the current considerations of surgical treatment for atrial functional regurgitation of the mitral and tricuspid valves based on the etiological mechanism.
