A 2-year-old girl was referred to the Harapan Kita National Heart Center due return of spontaneous circulation after cardiac arrest, bradyarrhythmia and repeated seizures with loss consciousness. She had been treated an epilepsy drug for 1 year. Electrocardiography during one episode showed complete heart block junctional escape rhythm QT interval prolongation, which then progressed torsades de...

We measured refractory periods at ventricular sites in the dog heart during drive from ventricular test sites and during combined drive from the test sites and other ventricular sites or the atrium. We found that ventricular activation sequence caused significant alterations on refractory period. Combined drive from two sites which resulted in fusion complexes was associated with shorter refrac...

Prostacyclins are vasodilatory agents used in the treatment of pulmonary arterial hypertension. The direct effects of prostacyclins on right heart function are still not clarified. The aim of this study was to investigate the possible direct inotropic properties of clinical available prostacyclin mimetics in the normal and the pressure-overloaded human right atrium. Trabeculae from the right at...

In vivo cardiac pressure and heart rate, and relative heart mass, have been measured in Busycon canaliculatum. Base pressure was about l-3cmH2O above ambient and effectively the same in the ventricle, atrium, pericardium and veins. Ventricular systolic pressures were very variable. Highest pressure was over 80cmH2O, but sustained levels were lower, up to about 40cmH2O. Heart rate was also very ...

major complications of heart transplantation include graft rejection, infection, graft arteriosclerosis, malignancy, and drug toxicity. among these complications, infections and thrombophilic disorders are of particular interest owing to their major contribution to morbidity and mortality among heart transplantation patients. thrombophilic disorders are caused by imbalance between hypercoagulat...

abstract background: primary cardiac lymphoma is extremely rare. case report: in this care report, we present the case of a 46-year-old man with primary cardiac lymphoma involving left atrium and interatrial septum, presenting as dyspnea palpitation and irregular heart beat. the diagnosis was obtained by transthoracic echocardiography and surgical biopsy with subxiphoid approach which revealed ...

BACKGROUND A free-floating ball thrombus in the left atrium is a rare clinical condition. However, the diagnosis of this condition has been facilitated by the advent and development of echocardiography and multi-detector row computed tomography (MDCT) and several cases have been reported. CASE REPORT We report a case of a 75-year-old woman who had recurrent giant spherical thrombi in the left a...

ALTHOUGH gross anatomic studies are frequently considered to be outmoded and outdated, we believe that because of its present practical importance a renaissance of the clinical anatomy of the heart1 is long overdue. Increasing interest in the group of lesions responsible for the somewhat controversial condition at present called "obstruc-tive cardiomyopathy" or "subaortic stenosis" has already ...

OBJECTIVES In this paper, we present an automatic method to segment four chambers by extracting a whole heart, separating the left and right sides of the heart, and spliting the atrium and ventricle regions from each heart in cardiac computed tomography angiography (CTA) efficiently. METHODS We smooth the images by applying filters to remove noise. Next, the volume of interest is detected by ...

Although in the pulmonary circulation small pressure differences may alter the categorisation of patients, there is no consensus on a standard zero reference level (ZRL). In the supine position, ZRL is mostly set at "5 cm below anterior thorax surface", "1/3 thoracic diameter below anterior thorax surface", "mid-thoracic level" or "10 cm above table level". We retrospectively assessed the dista...
