INTRODUCTION Atrial fibrillation was previously reported in patients with esophageal cancer as a complication of total esophagectomy or photodynamic therapy. Here, we propose that atrial fibrillation may also be caused by external compression of the left atrium by esophageal cancer. CASE PRESENTATION We present a 58-year-old man who developed atrial fibrillation with rapid ventricular rate in...

Secondary tumours of the heart are common, and where death is due to cancer the rate is 6-2 per cent (Willis, 1934). However, primary cardiac neoplasms are much rarer, occurring only about once in 60,000 necropsies (Cecil-Loeb Textbook of Medicine, 1963). About 35 per cent of primary heart tumours are myxomas, the remainder being angiomas, rhabdomyomas, leiomyomas, and their malignant counterpa...

Myxoma jantung merupakan tumor jinak primer yang paling umum, biasanya ada di atrium kiri dengan titik perlekatan daerah fossa ovalis. Modalitas pencitraan untuk diagnosis myxoma antaranya ekokardiografi, computed tomography (CT), magnetic resonance imaging (MRI). Cardiac is the most common primary benign heart tumor, usually in left with an attachment point ovalis area. Many modalities for car...

Heart rate responses to i.v. administration of cholecystokinin-8 (CCK-8) were investigated in Otsuka Long-Evans Tokushima Fatty (OLETF) rats lacking CCK-A receptors and control Long-Evans Tokushima Otsuka (LETO) rats. The heart rate decreased after i.v. administration of 3 nmolzkg of CCK-8 in LETO rats, but not in OLETF rats. Bradycardia in the LETO rats disappeared after treatment with MK-329,...

In an emerging bioelectronics era, there is a clinical need for physiological devices incorporating biofeedback that permits natural and demand-dependent control in real time. Here, we describe a novel device termed a central pattern generator (CPG) that uses cutting edge analog circuitry producing temporally controlled, electrical stimulus outputs based on the real time integration of physiolo...

BACKGROUND Recurrent hepatocellular carcinoma accompanied by a right atrial tumor thrombus is rare. No standard treatment modality has been established. Surgical treatment may be the only curative treatment; however, surgery has been considered high risk. We herein describe a patient who underwent resection of a recurrent right atrial tumor thrombus under normothermic cardiopulmonary bypass on ...

OBJECTIVE To evaluate the impact of the interatrial sulcus opening regarding of left atrium gain when harvesting heart and lungs for transplantation. METHODS It was evaluated the left atrium dimension, from the right mediastinal side, after the interatrial sulcus dissection in fifty human cadaver. The interatrial sulcus gain was related with gender, age and ethnic group. RESULTS The gain ob...

We have constructed and characterized two types of myosin heavy chain (MHC) cDNA clones (pHMHC2, pHMHC5) from a fetal human heart cDNA library. Comparison of the nucleotide and deduced amino acid sequences between pHMHC2 and pHMHC5 shows 95.1 and 96.2% homology, respectively. The carboxyl-terminal peptide and 3'-untranslated (3'-UT) regions are highly divergent and specific for these cDNA clone...

cor triatriatum is an acyanotic congenital heart disease. we present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. the 2d transthoracic echocardiography and the doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium  through restrictive opening to the low-pressure, dista...

Introduction Atrial fibrillation (AF) is rare in patients after orthotopic heart transplantation (OHT) and most commonly has been described in the setting of acute rejection or transplant vasculopathy. The principal reason postulated for the rarity of AF after OHT is the fact that the pulmonary veins and posterior left atrial (LA) wall are isolated as a direct result of the left atrioatrial ana...
