We experienced a giant biatrial myxoma concomitant with hepatocellular carcinoma. Most of myxomas originate from the left atrium, and biatrial myxomas are extremely rare. Excision of the giant cardiac tumor was performed to avoid risks of life-threatening complications. The resected mass was grossly composed of two parts with the border of interatrial septum and with the shape of peanut shell. Although microscopic examinations revealed enlarged vessels, hemorrhages and hemosiderosis in the left part and high cellularity with chronic inflammation in the right part, spindle-shaped cells in a loose myxoid stroma were observed in both parts of the tumor, consistent with the diagnosis of myxoma...

BACKGROUND: High resolution 3D T1 mapping is important for assessment of diffuse myocardial fibrosis in left atrium or other thin-walled structures. In this work, we investigated a fast single-TI 3D high resolution T1 mapping method that directly transforms a 3D late gadolinium enhancement (LGE) volume to a 3D T1 map. METHODS: The proposed method, T1-refBlochi, is based on Bloch equation modeling of the LGE signal, a single-point calibration, and assumptions that proton density and T2* are relatively uniform in the heart...

INTRODUCTION    Restoring sinus rhythm in patients with atrial fibrillation (AF)/atrial flutter (AFl) requires adequate oral anticoagulation prior to direct current cardioversion (DCC). Some patients eligible for DCC are not properly anticoagulated. OBJECTIVES    The aim of the study was to assess risk factors for thrombus and spontaneous echo contrast (SEC) in the left atrium (LA) as well as the safety profile of transesophageal echocardiography (TEE)-guided DCC in patients with inadequate anticoagulation...

Left atrial myxomas are the most common type of benign primary cardiac tumor. Patients can present with generalized symptoms, such as fatigue, symptoms from obstruction of the myxoma, or even embolization of the myxoma causing distal thrombosis. We describe a case with several-month duration of syncopal episodes that occurred after coughing and with exertion. Computed tomography of the chest showed a 6.1 cm by 4.5 cm mass in the left atrium, later evaluated with an echocardiogram. Cardiothoracic surgery removed the mass, and it was determined to be an atrial myxoma...

There are so far only a few reported cases of acute fulminant hepatic failure resulting from acute cardiomyopathy. This is a rare occurrence, especially in patients that do not exhibit any signs and symptoms of acute cardiac decompensation. We report a case of fulminant liver failure with nondiagnostic work up for the common causes of liver failure. This patient had concurrent history of congestive heart failure, but did not have acute decompensation. Right upper quadrant sonogram revealed hepatomegaly of 15 cm, trace amount of perihepatic ascites, pericholecystic fluid, and also thickened edematous gallbladder wall with no stones, no common bile duct stones, and no portal vein thrombosis...

BACKGROUND: Post-operative atrial fibrillation (POAF) frequently occurs after cardiac surgery. However, the mechanisms of POAF have not been fully elucidated. We aimed to examine whether pre-operative atrial gene expression related to cardiac metabolism is changed in patients with POAF. METHODS: Right atrial tissue was obtained during surgery from 38 patients who underwent cardiac surgery from 2013 to 2015. Atrial expression levels were determined by reverse transcription polymerase chain reaction for the following genes: glucose transporter type 4, peroxisome proliferator-activated receptor-α, fatty acid translocase, carnitine palmitoyltransferase 1B, and fatty acid binding protein 3 (FABP3)...

Cerebral embolism originating from intracardiac tumors represents a rare cause of stroke and has been documented in both adult and pediatric populations. We present a patient recently diagnosed with a right pulmonary hilum tumor, invading the pulmonary veins and the left atrium. Two consecutive episodes of large cerebral vessel occlusion in separate vascular territories occurred in the same day and were treated by mechanical thrombectomy. Embolic material retrieved on both occasions contained tumor fragments with peripheral endothelialization...

Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a nonmalignant disease of unknown etiology. It may present as bilateral, massive, painless cervical lymphadenopathy; however, one third of the cases have extranodal involvement. Extranodal sites include soft tissue, skin, upper respiratory and gastrointestinal tracts, and central nervous system, with head and neck being the most common. Here we report a rare case of intracardiac RDD in a 46-year-old, African-American female who presented with worsening shortness of breath and fatigue for 7 weeks...

BACKGROUND: Atrioventricular nodal reentry tachycardia (AVNRT) is common in adults and often involves reentry through two or more AV nodal-atrial connections. Although AVNRT can be a trigger for atrial fibrillation (AF), we have observed new onset AVNRT after AF ablation procedures. OBJECTIVE: To determine whether ablation involving the septum or proximal coronary sinus during AF ablation may create a substrate favorable for AVNRT METHODS: Cases of ablation for persistent AF who required a repeat ablation procedure between 2009 to 2016 were reviewed for diagnosis of AVNRT...

Background: Strenuous and endurance exercise training have been associated with morphological and functional heart remodeling. Two-dimensional speckle-tracking echocardiography (STE) is a novel technique that allows an accurate quantification of global myocardium deformation. Our aim was to evaluate together left and right cardiac remodeling in different long-distance running athletes: marathon runners (42 km) (M) and endurance mountain runners (>300 Km) (UT). Methods: A total of 92 athletes (70 males, 76%) including 47 M [age 45 ± 7 years; training: 18 (9-53) years(*)days/week], 45 UT [age 42 ± 9, training: 30 (15-66) years(*)days/week] underwent conventional echocardiography and STE (Beyond Diogenes 2...

BACKGROUND: Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging can be used to evaluate characteristics of atrial fibrosis. The novel noninvasive epicardial and endocardial electrophysiology system (NEEES) allows for the identification of sources with rotor activity. This study describes a new technique to examine the relationship between rotors and LGE signal intensity in patients with persistent atrial fibrillation (PERS) scheduled for ablation. METHODS AND RESULTS: Ten consecutive patients underwent pulmonary vein isolation for persistent atrial fibrillation...

Cor triatriatum sinistrum (CTS) is a congenital anomaly where the left atrium is divided into two compartments by a fibromuscular membrane. This report aims to add to the literature on a rare cardiac condition that can cause neurological morbidity. We report a case of a 19-year-old female with an infarct in the right middle cerebral artery (MCA) territory initially maintained on aspirin. Eighteen months later, she had recurrence of weakness, for which repeat transthoracic echocardiography (TTE) and re-evaluation of the first TTE demonstrated a hyperechoic membrane spanning the width of the left atrium, clinching the diagnosis of CTS...

Catheter ablation of atrial fibrillation is difficult when the left atrium is compressed by the vertebra. The heart may shift forward, and compression of the left atrium may be relieved in the left lateral decubitus position. Therefore, catheter ablation could be performed in the left lateral decubitus position even in such cases.

A 79-year-old woman was admitted with a left femoral neck fracture and she immediately developed circulatory shock. Echocardiography showed a markedly enlarged right ventricle (RV) with systolic ballooning of the mid-ventricular wall and preserved contractility of the apex. The left ventricular (LV) motion was normal. Multi-detector-row computed tomography showed severe congestion of the contrast media in the right atrium with no forward flow to RV, but no pulmonary embolism. She was successfully treated with percutaneous veno-arterial extracorporeal membrane oxygenation...

Recent experimental studies suggested direct effects of the anti-influenza drug oseltamivir on cardiac electrophysiology. We therefore aimed at analyzing potential antiarrhythmic effects of oseltamivir on atrial fibrillation (AF) in an experimental whole-heart model. Twelve rabbit hearts were isolated and Langendorff perfused. Thereafter, hearts were paced at cycle lengths of 350, 250, and 200 ms in the atrium. A standardized protocol employing atrial burst pacing induced AF in 4 of 12 hearts under baseline conditions (33%, 11 episodes)...

We report a rare case of dyspnea caused by a cardiac tumor in a 53-year-old woman. The patient had undergone a cardiac tumor (inflammatory myofibroblastic tumor, 6.2 × 4.2 × 3.3 cm) resection at our institute 13 months earlier. We performed preoperative evaluations which revealed a cardiac tumor originating from the posterior wall of the left atrium. Cardiac autotransplantation surgery (cardiac explantation, ex vivo tumor resection, cardiac reconstruction, and cardiac reimplantation) was successfully performed for the complete resection of the recurrent tumor without major postoperative complications...

Transradial access has been described in a variety of clinical contexts but has been rarely utilized for visceral artery interventions and during complex endovascular aortic aneurysm repair (EVAR) when upper extremity access is required. This is usually accomplished via brachial artery access, and although brachial access is generally safe and effective, radial access may offer some benefits with regard to patient comfort and potential complications. Here we report a case of successful delivery of a renal snorkel via a radial artery approach during EVAR...
