Mitral Valve Annular Dilatation Caused by Left Atrial Myxoma (original) (raw)

Mitral valve recurrence of a left atrial myxoma

European Journal of Cardio-Thoracic Surgery, 2002

Recurrence of intracardiac myxoma is unusual, and heart valves are extremely rare locations for this tumor to originate, either as the primary site or the site of recurrence. We present a case of non-familial cardiac myxoma, which after successful resection of the tumor mass from the left atrium, recurred in the atrial surface of anterior leaflet of the mitral valve, along with a review of similar cases in the literature. Myxoma was originally believed to recur due to inadequate resection, but recent data suggest the multicenteric disease to be the reason. Mitral valve myxoma mainly presents with symptoms of embolization and appears to affect women more often. It involves both leaflets with the same frequency and usually originates from the atrial side. Transesophageal echocardiography is the gold standard for non-invasive diagnosis and localization. Operative resection of the tumor along with the underlying tissue followed by suture repair of the valve and annuloplasty is recommended as the most appropriate treatment option. Long-term follow-up of patients by echocardiography is advised for early detection of any recurrence.

Giant Left Atrial Myxoma Causing Mitral Valve Obstruction and Concomitant Coronary Artery Disease

Cardiology Research, 2011

We describe a 56-year old male patient who presented with congestive heart failure and had undergone echocardiography that showed a mobile, giant left atrial mass which caused obstruction in the left ventricular outfl ow tract. The patient underwent a coronary angiography before operation that showed severe stenosis in the left anterior descending and circumfl ex artery. The patient underwent resection of the mass and coronary artery bypass grafting. The pathology of the mass was myxoma and patient had a satisfactory outcome.

Large left atrial myxoma with severe mitral regurgitation : The invertedt-shaped biatrial incision revisited

Texas Heart Institute Journal, 2006

Cardiac myxomas are primary cardiac tumors. In some cases of atrial myxoma, the standard left atriotomy alone does not enable safe tumor resection and easy access to the mitral valve. We report the cases of 2 patients with huge left atrial myxomas associated with severe mitral valve regurgitation who underwent an inverted T-shaped biatrial incision for tumor excision and mitral repair. This approach reduces tumor fragmentation and permits good mitral valve exposure.

Left Atrial Myxoma Causing Mitral Valve Obstruction with Right Ventricular Dysfunction Complicated by Atrial Fibrillation

Journal of Perioperative Echocardiography, 2019

Myxomas are the most common type of tumors of the heart and account for 83% of the primary tumors. The left atrium (LA) is the most common site for myxoma, followed by the right atrium. Obstructive symptoms of myxomas can mimic as mitral stenosis, and the severity increases due to an increase in heart rate such as the development of atrial fibrillation (AF). There is a high probability of developing pulmonary artery hypertension and right ventricular (RV) failure in patients with long-standing LA myxomas which can further be complicated by the development of AF. As the majority of patients with LA myxomas present late due to their nonspecific symptoms, a thorough assessment of pulmonary artery hypertension and RV function assessment should be done before surgical intervention.

Mitral Annular Disjunction in Advanced Myxomatous Mitral Valve Disease: Echocardiographic Detection and Surgical Correction

Journal of the American Society of Echocardiography, 2005

Mitral annular disjunction is a structural abnormality of the mitral annulus fibrosus described by pathologists in association with mitral leaflet prolapse and defined as a separation between the atrial wallmitral valve (MV) junction and the left ventricular attachment allowing for hypermobility of the MV apparatus. The transesophageal echocardiographic characteristics of this abnormality have not been previously described. In patients undergoing MV repair for myxomatous MV degeneration and evaluated using a standardized transesophageal echocardiographic protocol, annular disjunction (mean value 10 ؎ 3 mm) was seen at the base of the posterior leaflet in 98% of patients with advanced, and in 9% of patients with mild/moderate MV degeneration. There was a significant correlation between the magnitude of disjunction and the number of segments with prolapse/flail (r ‫؍‬ 0.397, P ‫؍‬ .001). We found annular disjunction to be a common component of MV apparatus in advanced MV degeneration. Its recognition on transesophageal echocardiography is important to facilitate optimal MV repair. The modification of the repair technique allows surgical correction of the annular disjunction, which seems to optimize long-term results in these challenging cases. (J Am Soc Echocardiogr

Giant left atrial myxoma mimicking severe mitral valve stenosis

International Journal of Cardiology, 2008

We report a case of giant left atrial myxoma in a young patient with clinical manifestation as congestive heart failure attributable to severe mitral valve stenosis. An early clinical and echocardiographic diagnosis was performed and the patient had an optimal outcome with surgery treatment.
