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.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

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.

Abstract A 62 year old gentleman presented with a history of recurrent central chest pains radiating to the left arm and jaw lasting up to 15-20 minutes and relieved with GTN. He had numerous admissions to hospital over a period of three years with negative Troponins and normal ECGs. There were several cardiovascular risk factors including obesity, diabetes, hypertension and dyslipidaemia. He also had a family history of ischaemic heart disease, with his mother and brother having heart attacks in their 60s. He was referred for outpatient investigations on multiple occasions but did not attend. This lead to a delay in a formal diagnosis until we eventually convinced him to undergo invasive diagnostic coronary angiography in June 2018. Prior to this, an Echocardiogram was done and showed reasonably preserved cardiac systolic function. Coronary angiography demonstrated unique anatomical distribution of the three main coronary vessels, with an anomalous origin of the left main system (LMS) and left sided arteries arising from the right coronary cusp. The right coronary artery stemmed from its natural position and was the dominant vessel. Hence, all the coronary arteries arose from the same cusp. The LMS was anomalous and hypoplastic; an exceedingly rare occurrence of less than 0.03%. These unusual findings were then confirmed on CT Coronary Angiogram. Although a surgical opinion was sought, the decision was a non-operative approach in view of no significant obstructive lesions and given the technical difficulties of undertaking coronary bypass. Viability imaging and ischaemia testing were then pursued with nuclear modalities. Ultimately, it was proven that the lesions did not show any significant reversible ischaemia and so a continued aggressive secondary prevention strategy was adopted. The patient is stable and doing well on optimal medical therapy. Abstract P1496 Figure. LMS Arising From Right Coronary Cusp

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.

Ossification of the Achilles tendon is a rare condition. We recently treated a patient with ossification of bilateral Achilles tendons. The patient was a 50 year old male whose chief complaint was discomfort around the Achilles tendon. He had a previous history of treatment of bilateral club feet On the roentgenograms, the length of the bony mass in the Achilles tendon was 5.5 cm on the right side and 1.5 cm on the left side. The left side was treated by surgical removal of a bony mass and suture of the tendon. Microscopic examination of the extirpated specimen revealed bone formation through enchondral and intramembranous ossification in the Achilles tendon.
