    Transcatheter aortic valve implantation (TAVI) is a safe and effective alternative to surgical valve replacement in intermediate and even in low-risk patient cohorts. Direct aortic (DAo) route may be used in patients with severe peripheral vascular disease. Here, we present an 88-year old patient hospitalized with cardiogenic shock. Echocardiography revealed severe aortic valve stenosis with aortic valve area 0.5 cm(2), mean gradient of 55 mmHg, and peak gradient 92 mmHg. TAVI was considered by the Institutional Heart Team. Multislice computed tomography (MSCT) revealed severe peripheral vascular disease, decreased calibration of abdominal aorta, and multiple large vulnerable atherosclerotic plaques. The patient was scheduled for a DAo TAVI. A 26-mm Medtronic CoreValve Evolut R valve was implanted after predilatation with median sternotomy. The patient was discharged after 96 hours. Although transfemoral (TF) access is used as the default approach for TAVI, it was contraindicated in our patient owing to severe peripheral vascular disease and decreased calibration of the abdominal aorta at its narrowest point (4.5 mm) with multiple large vulnerable atherosclerotic plaques. Careful preprocedural MSCT evaluation is essential and directly affects the success of the procedure. MSCT is also mandatory to confirm the best cannulation zone that must be met for a successful DAo TAVI.

    Evaluation of hs-CRP and sLOX-1 Levels in Moderate-to-High Risk Acute Coronary Syndromes
    (2020) Coner, Ali; Aydinalp, Alp; Muderrisoglu, Haldun; 0000-0002-9635-6313; 0000-0002-3761-8782; 30961517; AAG-8233-2020; AAD-5841-2021
    Objective: Risk stratification and prompt treatment are essential for the management of acute coronary syndromes (ACS) and prediction of future prognosis. Subclinical vascular inflammation and novel biomarkers play an important role in the clinical evaluation of ACS patients. Methods: We enrolled patients who were admitted to emergency service with unstable angina or non-ST segment elevated ACS (NSTE-ACS) in the study population. Coronary artery disease (CAD) complexity was determined via evaluation of angiographical views and peripheral venous blood samples were collected to measure highly sensitive C-reactive protein (hs-CRP) and soluble form of Lectin-like OxLDL receptor-1 (sLOX-1) levels. Results: A total of 40 patients were enrolled in the study population, mean age was 65.1 +/- 13.8 years and male gender percentage was 52.5%. Twenty-nine of patients had NSTE-ACS and 11 patients had unstable angina presentation. The modified Gensini scores were higher for patients with elevated hs-CRP and sLOX-1 levels. Conclusion: Vascular inflammation displays the onset of ACS and it is related to more complex CAD in these patients. An increase in sLOX-1 expression is closely related to anatomical complexity of CAD in ACS.
