AbstractCardiac Fibromas are primary cardiac tumours more common in children than in adults. Surgical intervention is often not required except in the case of limited cardiac output or significant arrhythmia burden. We present a symptomatic 3-month-old infant who had successful surgical intervention for a giant right ventricle fibroma found on prenatal imaging.

Abstract Benign primary cardiac tumours are rare, with lipomas accounting for <9% of them. Their presentation varies depending on the size and location of the tumour, with the majority of the cases being asymptomatic. We are presenting a case of an extremely rare primary heart-tumour infiltrating the right ventricle (RV) compromising its function. RV lipomas are so unusual that there are no clear treatment guidelines. In this case, we decided to treat the patient with surgical resection of the tumour. Although a total resection was not possible, due to the tumoural proximity to vital structures, a great portion of the tumour was removed, alleviating the patient’s symptoms.

Abstract Background Naso-ethmoidal meningoencephalocele is usually a congenital anomaly consisting of a protrusion of cerebral tissue and meninges into the ethmoidal labyrinth. The condition is a rare cause of structural epilepsy in dogs. We report the clinical presentation, surgical intervention, postoperative complications and outcome in a dog with drug resistant epilepsy secondary to a meningoencephalocele. Case presentation A 3.3-year-old male neutered Tamaskan Dog was referred for assessment of epileptic seizures secondary to a previously diagnosed left-sided naso-ethmoidal meningoencephalocele. The dog was drug resistant to medical management with phenobarbital, potassium bromide and levetiracetam. Surgical intervention was performed by a transfrontal craniotomy with resection of the meningoencephalocele and closure of the dural defect. Twenty-four hours after surgery the dog demonstrated progressive cervical hyperaesthesia caused by tension pneumocephalus and pneumorrhachis. Replacement of the fascial graft resulted in immediate resolution of the dog’s neurological signs. Within 5 months after surgery the dog progressively developed sneezing and haemorrhagic nasal discharge, caused by sinonasal aspergillosis. Systemic medical management with oral itraconazole (7 mg/kg orally q12h) was well-tolerated and resulted in resolution of the clinical signs. The itraconazole was tapered with no relapsing upper airway signs. The dog’s frequency of epileptic seizures was not affected by surgical resection of the meningoencephalocele. No treatment adjustments of the anti-epileptic medication have been necessary during the follow-up period of 15 months. Conclusions Surgical resection of the meningoencephalocele did not affect the seizure frequency of the dog. Further research on prognostic factors associated with surgical treatment of meningoencephaloceles in dogs is necessary. Careful monitoring for postsurgical complications allows prompt initiation of appropriate treatment.

Aim. Demonstration of potentials of preoperative planning and implementation of surgical resection in patients with adrenal cysts. A clinical observation of a successful surgical treatment of a rare pathology cyst of the right adrenal is presented. The choice of surgical treatment tactics is determined by the size of tumor and clinical presentation of the disease. The surgical treatment was accomplished laparoscopically which permitted to reduce the time of recovery and rehabilitation of the patient. In this clinical observation, the benefit of using 3D-modeling of the surgical area was shown for visualization of topographic and anatomic peculiarities and facilitation of the intraoperative navigation with the help of Avtoplan program developed by Samara State Medical University. Conclusion. Preoperative 3D-modeling permits to prepare to surgical intervention taking into account individual anatomic peculiarities of a patient, and to determine the optimal volume of the operation.

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.

AbstractObjective:Double-chambered right ventricle is characterised by division of the outlet portion of the right ventricle by hypertrophy of the septoparietal trabeculations into two parts. We aim to report our experiences regarding the presenting symptoms of double-chambered right ventricle, long-term prognosis, including the recurrence rate and incidence of arrhythmias after surgery.Methods:We retrospectively investigated 89 consecutive patients who were diagnosed to have double-chambered right ventricle and underwent a surgical intervention from 1995 to 2016. The data obtained by echocardiography, cardiac catheterisation, and surgical findings as well as post-operative follow-up, surgical approaches, post-operative morbidity, mortality, and cardiac events were evaluated.Results:Median age at the time of diagnosis was 2 months and mean age at the time of operation was 5.3 years. Concomitant cardiac anomalies were as follows: perimembranous ventricular septal defect (78 patients), atrial septal defect (9 patients), discrete subaortic membrane (32 patients), right aortic arch (3 patients), aortic valve prolapse and/or mild aortic regurgitation (14 patients), and left superior caval vein (2 patients). The mean follow-up period was 4.86 ± 4.6 years. In these patients, mean systolic pressure gradient in the right ventricle by echocardiography before, immediately, and long-term after surgical intervention was 66.3, 11.8, and 10.4 mmHg, respectively. There were no deaths during the long-term follow-up period. Surgical reinterventions were performed for residual ventricular septal defect (2), residual pulmonary stenosis (1), and severe tricuspid insufficiency (1).Conclusion:The surgical outcomes and prognosis of double-chambered right ventricle are favourable, recurrence and fatal arrhythmias are unlikely in long-term follow-up.

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.

Low Cardiac Output

Transesophageal echocardiography continues to be an indispensable postoperative diagnostic tool for cardiac surgical patients. Transesophageal echocardiography was carried out postoperatively in 30 consecutive hypotensive patients with low cardiac output who had undergone coronary bypass surgery. In 19 of these patients, a cause of low cardiac output requiring surgical intervention was excluded, and they were managed conservatively. In 11 patients, a surgical cause of low cardiac output was indicated: diffuse bleeding from no particular site in 5, and from a specific site in 6. They underwent urgent re-operation, and the echocardiography findings were confirmed on the operating table. Not only is transesophageal echocardiography important in diagnosis, but it is also highly specific in locating the site of bleeding.

Objectives: To assess the in vivo hemodynamic effects on the pressure overloaded right ventricle of RAS-Q® technology, the world’s first gas exchanger with a fully integrated compliance. Methods: In six acute in vivo trials RAS-Q was implanted in sheep between the pulmonary artery and left atrium. Right ventricular pressure overload was induced by pulmonary artery banding. Pressures and flows were recorded in baseline, moderate and severe pulmonary hypertension conditions. In one trial, RAS-Q was benchmarked against the pediatric Quadrox-i®. Results: With 1.00 and 1.17 L/min, RAS-Q delivered 31% and 39% of the total cardiac output in moderate and severe pulmonary hypertension, respectively. Pulmonary artery pressures and mean pulmonary artery pressure/mean arterial blood pressure ratio successfully decreased, implying a successful right ventricular unloading. Cardiac output was restored to normal levels in both pulmonary hypertension conditions. With both devices in parallel, RAS-Q provided three times higher flow rates and a 10 times higher pressure relief, compared to the pediatric Quadrox-i. Conclusion: A gas exchanger with a fully integrated compliance better unloads the right ventricle compared to a non-compliant gas exchanger and it can restore cardiac output to normal levels in cases of severe pulmonary hypertension.
