Ischemic stroke is uncommon in pediatric populations and is sometimes caused by cardiac myxoma. In such cases, neurological deficits initially present in ischemic stroke due to emboli or thrombi of the myxoma. Echocardiography is helpful to diagnose myxoma in a timely manner and allows urgent surgical resection of the myxoma. We report a successful case of myxoma in a 7-year-old boy who initially presented with left-sided hemiparesis.

Large intracavitary masses such as those occupying most of a cardiac chamber and obstructing blood flow are not routinely encountered in clinical practice. The differential diagnosis includes neoplastic as well as nonneoplastic causes. Primary cardiac tumors by themselves are uncommon. We hereby report a rare case of a middle-aged female presenting with New York Heart Association Class III symptoms, whose transthoracic echocardiogram revealed a huge mass in right-sided chambers with a novel double ball valve type movement...

Although a small number of atrial myxomas are found in association with congenital cardiac defects, ventricular myxomas coexisting with congenital cardiac anomalies are extremely rare. We report a case of right ventricular (RV) myxoma coexistent with atrioventricular septal defect in an adolescent. Echocardiography showed an RV mass, a small ostium primum atrial septal defect, and a cleft of the left atrioventricular valve. Magnetic resonance imaging revealed a mass, suggesting a myxoma. The mass was excised simultaneously with repair of the anomalies and was histologically confirmed as a myxoma...

Left atrial appendage mass can occasionally pose a serious challenge to physicians to identify the nature of the mass with the aid of imaging techniques. We present a case of 67-year-old man, who was evaluated for suspected left atria myxoma. Transesophageal echocardiography revealed a heterogeneous density originating from left atrial appendage, thought to be most consistent with a myxoma. Cardiac magnetic resonance imaging, uncharacteristically, gave an equivocal picture, suggesting the mass to be a myxoma on initial imaging and a thrombus with evidence of liquefaction necrosis following postcontrast enhancement...

BACKGROUND: Myxomas are the most frequent cardiac tumours. Their diagnosis requires prompt removal. In our centre, for valve surgery we use a minimally invasive approach. Here, we report our experience of cardiac myxoma removal through right lateral mini-thoracotomy (RLMT) with particular focus on its feasibility, efficacy and patient safety. METHODS: Between February 2006 and January 2017, 30 consecutive patients (aged 66±12.6years, range 35-83 years) underwent atrial myxoma resection through video-assisted RLMT...

Bilateral recurrence of atrial myxoma has been reported only a few times. We describe the case of a 41-year-old woman who had undergone left atrial myxoma resection and presented 9 years later with myxomas in both atria. The patient underwent successful resection of both masses with resolution of symptoms. We discuss the phenomenon of recurrent biatrial myxoma.

Atrial myxoma is a benign tumor of the heart that occurs primarily in the left atrium. Floating or large left atrial myxomas frequently cause functional mitral stenosis, may also affect mitral valve structure and flow, and lead to mitral regurgitation. Systemic embolization occurs in around 30% of cases either from tumor fragmentation or complete tumor detachment hence it should be removed as soon as it is detected. Intraoperative transesophageal echocardiography has a vital importance in the surgery. After resection of myxoma, intraoperative transesophageal echocardiography must be performed to rule out residual mass...

Background: Primary cardiac tumours are rare, and few studies have examined large samples. The aim of this study was to review a single institution's 15 years of experience with primary cardiac tumours. Methods: We conducted a retrospective analysis of 119 consecutive patients admitted to the Nanjing Drum Tower Hospital from April 2002 to January 2017. Five patients declined surgery due to illness or for financial reasons, and one patient underwent a second operation due to tumour recurrence 10 years after the first operation...

Background: This study aims to investigate the clinical and angiographic features in patients with acute myocardial infarction (AMI) induced by coronary artery embolism. Methods: Clinical data of five patients with AMI induced by coronary artery embolism were analyzed retrospectively. Results: One patient had left atrial myxoma, one patient had non-valvular atrial fibrillation, and three patients had rheumatic heart disease. Furthermore, one patient had mitral mechanical valve prostheses, two patients had atrial fibrillation...

The median sternotomy remains the standard approach in cardiovascular surgery but, in some conditions, it can be considered difficult to perform, especially in patients with history of esophagectomy. This case report describes a successful resection of a left atrial myxoma through a right anterolateral thoracotomy approach in a patient with a previous retrosternal gastric tube reconstruction. The decision for the best surgical approach was made after a heart surgery team discussion. Through this surgical access, a safe and excellent exposure of the left atrium was possible, and a complete resection of the myxoma was performed without any injury to the gastric tube...

We report an unusual presentation of a large left atrial myxoma in an eight-year-old girl who presented with the sudden onset of chorea. This case illustrates the fact that the presentation of chorea in nonendemic areas for rheumatic fever should raise suspicion for a myxoma. The chorea resolved soon after removal of the myxoma, supporting the hypothesis of an immune-mediated mechanism, or manifestation of paraneoplastic syndrome secondary to the myxoma.

Objectives: Although echocardiography has traditionally been used to diagnose myxoma, invasive or non-invasive coronary angiography can be useful diagnostic tool before surgery. Methods: We present a case of an angiographically detected left atrial myxoma feeding from the left circumflex coronary artery. Results: The patient underwent open-heart surgery to remove the left atrial myxoma. After ligation of feeding artery, the mass was successfully excised...

Cardiac myxomas are the most common cardiac tumors with diverse nonspecific clinical manifestations. A 78-year-old man presented to the emergency department with complaints of pain and coldness of the left lower extremity. The left femoral artery pulse was detected, while the pulses of the left popliteal, dorsalis pedis, and posterior tibialis arteries were absent. No blood inflow was detected in the superficial and deep femoral, popliteal, and anterior and posterior tibialis arteries. Thrombectomy was performed, and a fatty-like mass from the bifurcation of the common femoral artery and a thrombotic mass from the proximal portion of the superficial and deep femoral arteries were removed...

Myxomas are the most common cardiac tumors, accounting for about 50% of benign primary cardiac tumors, with the majority located in the left atrium, and 80% of which originate in the interatrial septum. We report two cases with severe cachexia, neurological sequelae, and severe biventricle dysfunction secondary to atrial myxomas with marked early improvement after tumor excision.

BACKGROUND: Cardiac myxomas are the most frequent primary benign intracardiac tumors. We reviewed our 27-year experience to evaluate factors associated with an embolism in patients with cardiac myxomas and their long-term outcomes. METHODS: A retrospective review identified 99 patients with cardiac myxomas between 1985 and 2012. Tumors were divided into two groups based on their gross external features. Tumors with a smooth regular border and a solid consistency were classified as solid; papillary myxomas were characterized by an irregular and gelatinous exterior with friable, soft consistency...
