Background. We studied the role of pulmonary veins in cancer progression using computed tomography (CT) scans. Methods. We obtained data from 260 patients with pulmonary vein obstruction syndrome (PVOS). We used CT scans to investigate pulmonary lesions in relation to pulmonary veins. We divided the lesions into central and peripheral lesions by their anatomical location: in the lung parenchyma...

Superficial veins of the head and neck are utilised for central venous cannulation, oral reconstruction and parenteral nutrition in debilitated patients. Clinical and sonological examinations of these veins may provide clues toward underlying cardiac pathology. Hence, although variations in these vessels are common, a sound knowledge of such variations becomes clinically important to surgeons, ...

Partial anomalous pulmonary venous connection is a rare congenital anomaly in which one or more pulmonary veins are connected to the venous circulation. The condition is frequently misdiagnosed, and usually identified by transesophageal echocardiography or invasive cardiac catheterization. We present the case of a 26-year-old female with new onset dyspnea on exertion who was diagnosed with the ...

A case is reported in which contrast angiography showed complete absence of the coronary sinus, the cardiac veins draining separately into left and right atria. Normal systemic venous drainage was demonstrated by contrast cross-sectional echocardiographic methods and later confirmed by conventional angiographic injections. In addition, angiography showed a stenosis in the anomalous cardiac vein...

Abstract Increased Body Mass Index (BMI) is often used as a predictor for cardiovascular diseases, and it also known to be associated with left atrial enlargement, potentially affecting anatomic structures of the atrium. The aim study was determine association between BMI parameters atrium, including characteristics pulmonary veins (PVs), found in cardiac computed tomography (CT) scan. retrospe...

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 ...

Three weeks later, the boy was still tachypneic and needed supplemental oxygen and nasogastric tube feeding. Cardiac catheterization was performed and showed normal pulmonary arterial pressure but left ventricle dilatation and high-output (8.4 liters/min) cardiac failure. Distended veins coming from the brain were seen and subsequently magnetic resonance angiography of the neurocranium was perf...

INTRODUCTION The long-term complications of catheter ablation within the pulmonary veins are unknown. The development of pulmonary vein stenosis has recently been described after catheter ablation to treat either chronic or paroxysmal atrial fibrillation. The purpose of this study was to examine the pathological and hemodynamic effects of radiofrequency (RF) energy application within the pulmon...

Introduction In the electrically nonisolated pulmonary veins, the cardiac autonomic system has been shown to play an important role in initiating pulmonary vein (PV) ectopy and triggering atrial fibrillation (AF). However, the effects of the cardiac autonomic system on the isolated PV are not currently known. We present the observations from a case where opportunistic stimulation of the autonom...
