Accurate morphological information on aortic valve cusps is critical in treatment planning. Image segmentation is necessary to acquire this information, but manual segmentation is tedious and time consuming. In this paper, we propose a fully automatic aortic valve cusps segmentation method from CT images by combining two deep neural networks, spatial configuration-Net for detecting anatomical landmarks and U-Net for segmentation of aortic valve components. A total of 258 CT volumes of end systolic and end diastolic phases, which include cases with and without severe calcifications, were collected and manually annotated for each aortic valve component. The collected CT volumes were split 6:2:2 for the training, validation and test steps, and our method was evaluated by five-fold cross validation. The segmentation was successful for all CT volumes with 69.26 s as mean processing time. For the segmentation results of the aortic root, the right-coronary cusp, the left-coronary cusp and the non-coronary cusp, mean Dice Coefficient were 0.95, 0.70, 0.69, and 0.67, respectively. There were strong correlations between measurement values automatically calculated based on the annotations and those based on the segmentation results. The results suggest that our method can be used to automatically obtain measurement values for aortic valve morphology.

We report the case of a 63-year-old woman who had an incidental echocardiographic diagnosis of papillary fibroelastoma (PFE) of the right coronary cusp of the aortic valve. The patient was informed about the embolic risk due to the pedunculated mass located on the aortic valve but she refused the proposed surgical removal. She was followed up yearly, and each follow-up included an echocardiographic evaluation of the mass. The lady is taking lysine acetylsalycilate 160 mg daily, and after more than 19 years later, she does not complain any symptoms or complications as a result of possible embolic episodes. If on one hand, our report is provocative for PFE nonsurgical management; on the other, we do believe that in symptomatic patients PFE located in the left heart chambers, the standard of care remains surgical excision after diagnosis. Anyway, our analysis shows that further data in this issue are needed in asymptomatic patients, and surgical indication should be proposed considering carefully the risk-benefit balance.

Placing annular sutures at the right coronary cusp is difficult during minimally invasive aortic valve replacement. We propose the partial everting mattress method, whereby a prosthetic valve is implanted ina supra-annular position at the left coronary and noncoronary cusps, with pledgets on the left ventricular side, but in an intra-annular position at the right coronary cusp, with pledgets on the aortic side. Needles can be grasped in forehand pass at all three coronary cusps. Our method enables easy placement of annular stitches even in the small surgical field, without adversely influencing the hemodynamic performance of the prosthesis.

We present a rare case of papillary fibroelastoma (PFE) of the aortic valve diagnosed after being referred from a pre-anesthesia clinic. This patient presented in preanesthesia clinic for assessment prior to right total knee replacement. Along with other investigations, echocardiography was ordered as the patient had a previous history of ischemic heart disease with angioplasty. There was no previous echocardiogram (ECHO) in the patient records. An incidental finding of a sclerotic aortic valve with highly mobile mass was seen attached to the right coronary cusp on the aortic side with same echogenicity as the valve. Based on this rare finding, the patient was referred to an interventional cardiac center prior to an elective orthopedic surgery.Citation: Abdullah A, Fouad A, Esmat AM, Elhefnawy A, Adeel S.

Abstract Introduction Splenic abcess represents a rare complication of left-sided infective endocarditis. Unlike splenic infarction, which is a more benign condition, splenic abcess requires rapid diagnosis and treatment as its course can be fatal. We present the case of a 52- year old male, with diabetes and hypertension, admitted for shortness of breath and fever in the past two months. Clinical examination revealed respiratory distress, tachypnea, diastolic murmur on the left sternal border. Baseline laboratory investigations showed elevated inflammation markers, leukocytosis and thrombocytosis. Enterococcus faecalis was isolated from the hemocultures. Transthoracic echocardiography revealed a dilated left ventricle (LV), with preserved LV ejection fraction, with severe aortic regurgitation due to valve destruction. A large (11mm diameter) vegetation-like structure attached to the ventricular side of the right coronary cusp, protruding into the left ventricular outflow tract was identified. Further evaluation by transoesopahgeal echocardiography did not identify other lesions, except for secondary moderate mitral regurgitation, with intact mitral leaflets. Dual antibiotic therapy with Ampicilin and Gentamycin was initiated. Surgery was planned after infection control. The first three days were uneventful, with rapid resolution of fever and inflammatory markers, but on the fourth day, the patient developed severe abdominal pain, with its focal point in the left hypochondrium. Contrast abdominal CT was performed and large multiple subcapsular lesions were identified. These findings, correlated with the symptomatology, suggested embolic splenic abcess and infarction. The patient successfully underwent laparoscopic splenectomy, but soon after he developed sepsis with respiratory failure and neurological deterioration (with normal CT scan) and was admitted to the intensive care unit, where he was intubated and mechanically ventilated. Consensus after discussions between cardiology, cardiac surgery and neurology services was to immediately replace the aortic valve, given the inability to otherwise control the infection. Intraoperative images were consistent with perforation of the right coronary cusp. During hospitalization in the ICU following cardiac surgery, the patient was extubated and his neurological function markedly improved. Repeated TTE and TEE showed normal prosthetic valve function and resolution of mitral regurgitation. The patient continued to improve clinically until his discharge. Conclusions We presented a case of a rare pathogenic entity- splenic abscess and infarction- due to systemic embolization from infective aortic valve endocarditis. Multidisciplinary teamwork was required between cardiologist, intensive care specialist, neurologist, infectionist, general surgeon and cardiac surgeon. Splenectomy was performed before valve replacement, a treatment-course characteristic in the occurrence of these rare cases.
