The present study shows that the procedure of LSA revascularization as part of TEVAR is safe with low morbidity consisting of mainly (transient) nerve palsy.

SUMMARYA young male patient was evaluated for a cardiac cause of ischaemic stroke. In the work-up, a tumour was detected on the subvalvular apparatus of the mitral valve for which operative removal was scheduled. A portaccess procedure was applied as a novel way of treatment. On thoracoscopic intracardiac inspection, however, multiple tumours were seen attached to the chordae tendineae and to the anterior leaflet of the mitral valve. It was decided to not to perform a plasty but to remove the valve in toto and insert a mechanical valve prosthesis. The tumours were diagnosed as multiple giant Lambl's excrescences. BACKGROUND

A cardiac papillary fibroelastoma (CPFE) is reported to be the second most common cardiac neoplasm after myxoma cordis. CPFEs are histologically benign, frequently asymptomatic, but highly thrombogenic, which could lead to systemic and peripheral embolization. We present a case of a 68-year-old-patient, with a history of angioosteohypertrophy syndrome, who presented at our emergency department (ED) with symptoms of transient ischemic attacks. A thorough investigation, including echocardiography, revealed a neoplasm on the left coronary cusp (LCC) of the aortic valve. The neoplasm was resected via a valve-sparing shave via the right anterior thoracotomy (RAT). The pathological assessment confirmed it to be CPFE. CPFE is a rare but treatable cause of thromboembolism. The removal of CPFEs has classically been performed through a full median sternotomy. We like to present the first case of a valvesparing removal of a CPFE on the aortic valve through a RAT approach.

Objectives: Limited aortic annulus exposure during minimal invasive aortic valve replacement (mini-AVR) proves to be challenging and contributes to procedure complexity, resulting in longer procedure times. New innovations like sutureless valves have been introduced to reduce procedure complexity. Additionally, preoperative imaging could also contribute to reducing procedure times. Therefore, we hypothesize that Computed Tomography (CT)-image based measurements are associated with mini-AVR complexity. Methods: One hundred patients who underwent a mini-sternotomy and had a preoperative CT scan were included. With a CT-based mini-AVR planning tool, we measured access distance, access angle, annulus dimensions, and calcium volume. The associations of these measurements with cardiopulmonary bypass (CPB) time and aortic cross-clamp (AoX) time were assessed using univariable and multivariable regression models. In the multivariable models, these measurements were adjusted for age and suture technique. Results: In the univariable regression models, calcium volume and annulus dimensions were associated with longer CPB and AoX time. After adjusting for age and suture technique, increasing calcium volume was still associated with longer CPB (adjusted β-coefficient 0.002, 95%-CI (0.005, 0.019), p-value = 0.002) and AoX time (adjusted βcoefficient 0.010, 95%-CI (0.004, 0.016), p-value = 0.002). However, after adjusting for these confounders, the association between annulus dimensions and procedure times lost statistical significance. Conclusion: Increase in calcium volume are associated with longer CPB and AoX times, with age and sutureless valve implantation as independent confounders. In contrast to previous studies, access angle was not associated with procedure complexity.
