Echocardiographic Findings

Congenital heart defects have been occasionally reported in cattle and ventricular septal defect represents the most frequently encountered anomaly. The double-outlet right ventricle is a rare congenital ventriculoarterial malformation reported only in certain cattle breeds. We describe this rare and complex congenital cardiac malformation observed in a 10-day-old male Chianina calf. Clinical examination showed tachycardia, tachypnea, jugular pulses, cyanotic mucous membranes and a right apical systolic murmur. Transthoracic echocardiography revealed severe dilation of the right-sided cardiac chambers with a markedly hypoplastic left ventricle. Both aorta and pulmonary artery leaving the right ventricle in parallel alignment with the tricuspid valve were suggestive of a dual-outlet right ventricle. Interventricular and interatrial septal defects were also visualized. Post-mortem examination confirmed the echocardiographic findings. To the authors’ knowledge, a similar complex congenital cardiac malformation has not been reported in calves of the Chianina breed to date.

Abstract A 68-year-old man was admitted to the hospital with complaints of pain in the lumbar spine. He had L5 disc herniation, Spinal stenosis of the L5 root canal - S1 on the right in the past medical history. Percutaneous vertebroplasty at the level of L3 and Th8 vertebral bodies was performed six months ago due to painful vertebral hemangioma. The man is suffering from arterial hypertension, receives antihypertensive therapy. During routine transthoracic echocardiography, a hyperechoic structure with a size of 9.5 x 0.9 cm was found in the right atrium and right ventricle. Chest computed tomography with contrast enhancement revealed signs of bone cement in the right atrium and right ventricle, in the right upper lobe artery, in the branches of the upper lobe artery, in the paravertebral venous plexuses. Considering the duration of the disease, the stable condition, the absence of clinical manifestations and disorders of intracardiac hemodynamics, it was decided to refrain from surgical treatment. Antiplatelet therapy and dynamic observation were recommended. Conclusion Percutaneous vertebroplasty is a modern minimally invasive surgical procedure for the treatment of degenerative-dystrophic diseases of the spine. However, the cement can penetrate into the paravertebral veins and migrate to the right chambers of the heart and the pulmonary artery. This clinical case demonstrates asymptomatic cement embolism of the right chambers of the heart and pulmonary artery after percutaneous vertebroplasty, detected incidentally during routine echocardiography.

The Relationship

Jugular venous pressure reflects right atrial pressure and the relationship between right atrial filling and emptying into the right ventricle. Changes in wave amplitude may indicate structural disease and rhythm changes. Normal jugular venous pressure is 6 to 8 cm H2O. It is best evaluated with the patient supine at an angle of at least 45°. The right atrium lies 5 cm below the sternal angle, and thus the estimated jugular venous pressure equals the height of the jugular venous pressure above the sternal angle + 5 cm.

Point Of Intersection

What does right atrial pressure (PRA) do to cardiac output (CO)? On the one hand, we've been taught that PRA represents preload for the right ventricle. That is, the higher the PRA, the greater the right ventricular output (and, therefore, CO). This is simply an application of Starling's law to the right side of the heart. On the other hand, we've been taught that PRA represents the downstream impedance to venous return (VR) from the periphery. That is, the higher the PRA, the lower the VR, and therefore, the lower the CO. The point of intersection between the 2 curves defines a unique blood flow rate, which is both CO and VR at the same time.

We report the case of a patient with a giant right atrial myxoma that remained clinically silent until it almost completely obliterated the right atrium, prolapsed into the right ventricle and obstructed the tricuspid valve inflow. This case illustrates the importance of rapid surgical intervention in the setting of acute heart failure caused by tumor masses obliterating heart valves or cardiac chambers.

AbstractIntracardiac teratomas are rare primary tumours. We report the case of an infant prenatally diagnosed with an isolated multi-cystic mass developed in the right ventricle causing neonatal refractory ventricular arrhythmia. Despite rescue extracorporeal support and partial surgical resection, he died as almost all the previous reported perinatal intracardiac teratomas whatever the prenatal tolerance and the size of the tumour. The common poor outcome of fetal intracardiac teratomas should be known when counselling parents during pregnancy.

Right Ventricular Dilation

Ebstein's malformation is a congenital anomaly of the tricuspid valve and right ventricle that is characterized by several features, each of which can exhibit a spectrum of malformation. The first is adherence of the leaflets of the tricuspid valve to the underlying myocardium, this representing failure of delamination during development. This feature involves the septal and inferior leaflets, but rarely the anterior leaflet (Fig. 1). The second feature is anterior and apical rotational displacement of the functional annulus (Fig. 2). The third abnormality is dilation of the “atrialized” portion of the right ventricle, with variable degrees of hypertrophy and thinning of the wall. The fourth finding is redundancy, fenestrations, and tethering of the anterior leaflet. A fifth abnormality is dilation of the right atrioventricular junction, this being the true tricuspid valvar annulus. The final feature is variable ventricular myocardial dysfunction. Each heart with Ebstein's malformation is different, and there is an infinite variability that can occur with the above mentioned characteristics. These anatomical and functional abnormalities cause important tricuspid regurgitation, which results in right atrial and right ventricular dilation, and atrial and ventricular arrhythmias.

Echocardiographic Findings

AbstractThe objective of this study was to review the echocardiographic findings and autopsy correlates of pulmonary atresia with an intact ventricular septum when diagnosed during fetal life. All cases with this lesion (nearly 60) seen in the Perinatal Cardiology unit of Guy's Hospital since 1983 are part of this study. More than half of the cases were detected within the last two years, and all bar three were referred because of suspicion of a cardiac malformation detected on routine obstetric scanning. The cases were divided into two distinct groups. On the one hand were those with dilatation of the chambers of the right heart. These had a uniformly poor prognosis. Severe regurgitation of the tricuspid valve was a characteristic feature. On the other hand were the cases with cavitary hypoplasia due to mural overgrowth. Direct measurements of pressure in one such case revealed suprasystemic values in the right ventricle. Although contemplated, fetal intervention proved impossible. Autopsy revealed cases with either valvar or infundibular atresia. In most cases diagnosed prior to 24 weeks of gestation, mothers opted for termination of pregnancy. All cases with dilatation of the right ventricle died. Of pregnancies which continued, only 30% of children are still alive, all but one being less than two years of age at present. The use of cross-sectional and Doppler echocardiography permits the accurate diagnosis of pulmonary atresia with an intact ventricular septum during fetal life. Autopsied cases showed strong correlation with the echocardiographic findings. The poor prognosis in most cases warrants consideration in the future of intervention during fetal life.
