Direct aortic transcatheter aortic valve implantation.

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 cm², 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.

Periodontal status and dental behaviour of heart transplant recipients and healthy controls.

Objective: The aim of this study was to compare the periodontal status and dental behaviour of heart transplant recipients with systemically healthy controls.Material and Methods: Forty heart transplant recipients and 40 systemically healthy patients were included. A questionnaire was used to record demographic, systemic health and dental behaviour data, and the following clinical parameters were recorded: plaque index, bleeding on probing, probing depth, gingival recession, and clinical attachment level.Results: Mean probing depth (p = .045), mean gingival recession (p = .016), mean clinical attachment level (p = .021) and mean plaque index scores (p = .001) were higher in heart transplant recipients than the systemically healthy group. However, bleeding on probing was similar in both groups (p > .05). Tooth brushing frequency and number of participants who used dental floss/interdental brush was lower in the heart transplant group.Conclusion: Considering the poor oral hygiene and high clinical periodontal parameters of heart transplant recipients, periodontal evaluation should be done regularly before and after transplantation. The patient's daily oral hygiene regimens should be evaluated carefully in this evaluation session and modified based on their gingival health, manual skill and motivational levels. The importance of oral health and its effects on systemic health should also be explained to the transplant recipients in detail.
