Background: Neonatal thrombotic diseases can cause mortality or serious morbidity and disability.Case report: In this report, we present a case of neonatal inferior vena cava thromboembolism with several underlyingfactors. Hereditary thrombophilia and genetic mutation in plasminogen activator inhibitor-1 and MTHFR A1298C genesin conjunction with cleft palate resulted in poor l...
it has been well - established that common atrial flutter is due to intraatrial macroreentry and its reentry circuit locates in the right atrium. this reentry circuit has been characterized to involve an area of slow conduction identifiable electrophysiologically at the low posteroseptal right atrium and anatomical narrow isthmus snrrounded by the inferior vena capa, coronary sinus astium and t...
The effects of the site used for atrial pacing on atrial and atrioventricular nodal conduction were assesed in 16 patients. In 13 patients, three atrial pacing sites were used: high right atrium, low lateral right atrium, and midcoronary sinus. Two recording sites were used: low septal right atrium, including His electrogram, and high right atrium. Stimulus (S) to high right atrium interval was...
Figure 1: Echocardiography showing, a large fistula with a diameter of 7 mm between the right pulmonary artery and the enlarged left atrium (A and B), CT scan showing an epidural hematoma (C). RA: right atrium; LA: left atrium; RPA: right pulmonary artery; AO: aorta; PA: pulmonary artery; RVOT: right ventricular outflow tract. Figure 2: Intraoperative view of the doubly ligated fistula between ...
Although cardiac tumor is rare, cardiac myxoma is the most common primary cardiac tumor in adults (50%-70%). Myxoma, as a benign neoplasm, can develop in any chamber of the heart the most common site being the left atrium (75%) with an overall incidence of about 0.5/million/year. Nowadays echocardiography plays a crucial role in early precise diagnosis and treatment and, therefore, prevents lif...
BACKGROUND Prolonged and fractionated right atrial endocardial electrograms are characteristic of paroxysmal atrial fibrillation (idiopathic or associated with sick sinus syndrome). The distribution of these abnormal atrial electrograms within the right atrium and the way it is related to the likelihood that patients with sick sinus syndrome will develop paroxysmal atrial fibrillation was studi...
