Abstract

A 44‐year‐old woman who was quarantined for 5 days after the diagnosis of coronavirus disease of 2019 (COVID‐19) was transferred to our hospital with the complaint of chest pain. The patient was unvaccinated. Electrocardiography revealed ST elevation in the lateral leads. Echocardiographic biventricular dysfunction with oedematous wall thickening was identified. Cardiac enzyme levels were elevated; however, C‐reactive protein (CRP) levels, and the coronary angiogram were normal. The patient required mechanical circulatory support to stabilize haemodynamics and was treated with remdesivir, baricitinib, and intravenous methylprednisolone. She recovered after 13 days of mechanical support. Serial cardiac magnetic resonance imaging revealed acute myocardial oedema and subsequent fibrosis. An endomyocardial biopsy on admission showed mild interstitial inflammatory infiltrates with endomyocardial fibrous thickening and mild interstitial fibrosis of the myocardium. Normal CRP levels suggested minor involvement of interleukin (IL)‐6, supporting the efficacy of baricitinib. [ABSTRACT FROM AUTHOR]

Abstract

Open in new tab Download slide OBJECTIVES There are few reports on the rotational position of the aortic valve relative to the base of the left ventricle, and its influence on valve-sparing aortic root replacement (VSRR) has not been reported. Based on our experience with complications such as right atrial perforation and tricuspid valve injury, we investigated the cause of these complications in terms of morphological variations in the aortic root and its surrounding structures. METHODS The aortic valve rotation relative to the base of the left ventricle was assessed in 30 patients with tri-leaflet aortic valves who underwent VSRR. The influence of such anatomical variations on surgical procedures was investigated. RESULTS The aortic valve was positioned normally in 25 patients (83.3%), rotated counterclockwise in 4 (13.3%), and rotated clockwise in 1 patient (3.3%). In patients with a counterclockwise rotated aortic valve, the non-coronary sinus was the largest compared with other sinuses. This aortic valve rotation could be diagnosed by multidetector row computed tomography. In all patients who had difficulty in the external dissection of the right sinus of Valsalva, the aortic valve was counterclockwise rotated and forcible dissection had a risk of right atrial perforation and tricuspid valve injury. CONCLUSIONS Aortic valve rotation is an element that complicates VSRR. The rotational position of the aortic valve can be diagnosed preoperatively using multidetector row computed tomography and understanding the anatomy of the aortic valve related to rotational position help decide proper surgical decision-making in performing aortic root reconstruction procedure.

24. Coronary Ostial Patch Angioplasty With Femoral Artery in Takayasu Arteritis.

Abstract

Takayasu arteritis (TA) occasionally involves the coronary ostium leading to myocardial ischemia. Although surgical coronary ostial angioplasty is desirable for ostial stenosis, the patch materials and long-term results are controversial. We used femoral artery (FA) as a patch material for coronary ostial angioplasty in 3 TA patients. Coronary ostial enlargement with a longitudinal incision followed by rectangular FA patch augmentation was performed to extend the narrowing coronary ostium. In all patients, coronary ostial stenosis was successfully repaired. Ostial angioplasty using an FA patch would be a reasonable surgical strategy to treat coronary ostial stenosis in TA.
