We report a patient with a large mass in the right atrium with tricuspid valve involvement resulting in significant stenosis, which was a tuberculoma without active pulmonary disease. Cardiac tuberculoma is rare and usually involves the pericardium. Myocardial involvement is a very rare occurrence. 

A patient is described in whom a large congenital aneurysm or diverticulum of the right atrium caused repeated attacks of supraventricular arrhythmia and a strikingly reduced cardiac output. The aneurysm, which contained a large thrombus, was demonstrated by preoperative angiographic examinations. At the time of operation, regular rhythm returned at the moment the aneurysm was transsected. The ...

Presence of a persistent left superior vena cava (PLSVC) is generally clinically asymptomatic and discovered incidentally during central venous catheterization. However, PLSVC may cause technical difficulties during cardiac device implantation. An 82-year-old man with heart failure symptoms and an ejection fraction (EF) of 20% was scheduled for resynchronization therapy-defibrillator device (CR...

Introduction. Venous thromboembolic disease is a common complication found in 8% of patients with acute myeloid leukemia. The location at the right atrium is exceptional. These last fifty years, only 6 cases of thrombosis of the atrium in the diagnosis of acute myeloid leukemia were published on PubMed search engine. Case Presentation. 35-year-old farmer, who had been admitted by emergency depa...

The duration of the monophasic action potential (APD), the interval between atrial beats and the delay time between excitation of the right and left atria of dogs were measured, using coaxial suction electrodes, before and during vagal stimulation. The effect of vagal stimulation on the degree of shortening of APD varied at different recording sites in the atrium, the shortening being more pron...

(A) Chest X-ray after pacemaker implantation (A). (B) Four days later, chest X-ray showed the displacement of the leads into the right atrium and the superior vena cava, with both the leads being wrapped around the pacemaker generator. (C) A few months later, a repeat chest X-ray showed a similar displacement of both the leads. A 67-year-old woman who underwent pacemaker implantation 4 days ago...

BACKGROUND Platypnea-orthodeoxia syndrome is a rare syndrome characterized by dyspnea and hypoxia when the patient is sitting or standing. Here we report a case of platypnea-orthodeoxia syndrome caused by a right hemidiaphragmatic elevation with giant liver cyst that triggered a right-to-left shunt through the patent foramen ovale. This case report is the first presentation of a case secondary ...

Although it is rare, the right atrium can be encroached on by abnormal mediastinal structures, including aortic aneurysms, carcinomas, hepatic cysts and diaphragmatic paralysis. Extrinsic compression of the right atrium causes significant hemodynamic compromise and can lead to fatal outcomes. We describe the case of a 66-year old man with a past history of pulmonary tuberculosis that had underg...

A report is made of a rare case of Wilms' tumour which simulated clinically a syndrome of ;right heart failure', as found in some cases of Ebstein's disease. The clinical, radiological, and electrocardiographic study led to the suspicion of this type of malformation. The cine-angiographic study revealed two important facts: the impossibility of approaching the inferior vena cava with opaque mat...

An 11-year-old mixed breed dog was presented with signs of anorexia. Radiographic and ultrasound examinations revealed a large mass in the heart, between the right atrium and the right ventricle. Upon gross inspection, a multilobulated tumor arising from the right atrial wall and occupying the right atrium was identified. Microscopical analysis demonstrated that this tumor consisted of neoplast...
