heart murmurs/hypoxia

Acute hypoxemia produces opposite effects on the pulmonary and systemic vascular resistance. To assess the influence of acute hypoxemia on cardiac murmurs, 36 patients with a single valvular or congenital heart lesion were studied. As expected from these hemodynamic effects, right-sided regurgitant

We report a venous oxygen embolism that occurred in a 66-yr-old man after 60 mL of 3% hydrogen peroxide was injected into a perianal fistula intraoperatively to locate its internal opening. The diagnosis was made after detecting hypoxemia, decreased end-tidal carbon dioxide tension, systemic

Surgical correction greatly decreases the mortality and cardiac morbidity of cyanotic congenital heart disease, but children remain at risk of long term difficulties in other areas. A historical cohort study was conducted to determine the relation between heart disease and school performance in 29

BACKGROUND Complete transposition of the great arteries is a congenital cardiac malformation occasionally encountered in cattle and other species. The objective of the present report was to provide a detailed clinical, echocardiographic and post mortem description of a calf presenting with this

Two half-sibling neonatal llamas (Lama glama) and one unrelated adult llama were presented with various complaints, including failure to thrive, respiratory distress, and excessive recumbency. The related camelids were born in successive years to the same dam but from unrelated sires. Thoracic

A case of pulmonary arteriovenous fistula (PAVF) complicated by brain abscess is presented. The incidence of this complication has been quoted to be 1-5%. After reviewing all inpatients in Chang Gung Memorial Hospital from 1977 to 1988, we found a total of 9 cases of PAVF; only one case of PAVF

The frequency and clinical differences between several types of TGA have been estimated. In a group of 52 patients with TGA three anatomic types were distinguished on the basis of the classification of Nadas (Fig. 1). The correlation between TGA type and sex, weight at birth, predominating clinical

Hypoplastic left heart syndrome (HLHS) refers to the abnormal development of the left-sided cardiac structures, resulting in obstruction to blood flow from the left ventricular outflow tract. In addition, the syndrome includes underdevelopment of the left ventricle, aorta, and aortic arch, as well

An approximately 6-mo-old female bald eagle (Haliaeetus leucocephalus) was presented for an inability to fly and bilateral drooped wings. Pectoral muscle atrophy with a moderate polycythemia was present. Over the course of 3 wk, there were no improvements in flight capacity, although the bird gained

BACKGROUND Although infective endocarditis has changed in the recent past as a result of microbiologic and risk factors, it continues to be clinically challenging. The disease is characterized by the formation of septic masses of platelets on the surfaces of heart valves. Several mechanisms can

A captive, 22-year-old, intact male Sunda wrinkled hornbill (Aceros corrugatus) was presented for an acute onset of open-mouth breathing and bilaterally drooped wings. An external physical examination revealed a moderately thin body condition, marked respiratory effort, and a significant

Primary tumors of the heart are infrequent at all ages. We present a newborn with hypoxia and a heart murmur, in whom an echocardiogram revealed a large tumor filling the right ventricle and the pulmonary annulus. To maintain pulmonary blood flow, the patency of the ductus arteriosus was achieved by

An 8-year-old, intact male Persian cat was presented with a prominent heart murmur, exercise intolerance, anorexia, and periodontitis. There was no cyanosis and no laboratory evidence for systemic hypoxemia. Echocardiography showed a dextropositioned aorta, moderate pulmonic stenosis (maximal

Respiratory and cardiac diseases are common in older horses. Advancing age is a specific risk factor for cardiac murmurs and these are more likely in males and small horses. Airway inflammation is the most common respiratory diagnosis. Recurrent airway obstruction can lead to irreversible structural

Intracardiac masses in infancy are not common. Tumors, thrombi and vegetations of bacterial endocarditis are exceedingly rare in this age group. These masses are seldom diagnosed before the infant's death. Two-dimensional echocardiography is a noninvasive technique that can detect and differentiate
