- OBJECTIVESLarge series of percutaneous femoral access for extracorporeal circulation in minimally invasive cardiac surgery (MICS) are scarcely reported.METHODSThis is a single-centre study describing the use of percutaneous femoral access in patients undergoing MICS via minithoracotomy. Femoral artery closure was performed with a plug-based closure device. To reduce the risk for vascular complications, intraoperative ultrasound assessment of correct deployment of the arterial closure device was done during the later period of the study.RESULTSDuring a 5-year period, 650 patients underwent percutaneous femoral cannulation and decannulation with device closure of the femoral artery puncture. Two hundred and seven patients (31.8%) were operated in the early phase of the experience (August 2017–August 2019), without the use of intraoperative ultrasound assessment of closure device deployment. During the later period of our experience (August 2019–September 2022), 443 patients (68.2%) were operated, of whom all underwent intraoperative ultrasound assessment of closure device deployment. Of the patients operated without intraoperative ultrasound assessment, 6 patients (2.9%) experienced vascular complications compared with none of the patients in whom intraoperative ultrasound-assessment was used (P < 0.001). In total, 15 patients (2.3%) underwent conversion to surgical cutdown owing to incomplete haemostasis or femoral artery stenosis/occlusion and the mechanism was intravascular deployment of the closure device in all 15 cases.CONCLUSIONSPercutaneous femoral access in MICS is safe and the need for surgical cutdown was infrequent. The risk for vascular complications is minimized with the use of intraoperative ultrasound assessment of the correct positioning of the vascular closure device.CLINICAL TRIAL REGISTRATION NUMBERhttp://www.clinicaltrials.gov; Unique identifier: NCT05462769.

- Minimally invasive cardiac surgery such as a mitral valve procedure requires femoral arterial cannulation for extracorporeal circulation. To avoid complications associated with surgical groin incisions, such as seromas and infections, percutaneous cannulation techniques can be used. This video tutorial illustrates percutaneous femoral cannulation and decannulation using a plug-based vascular closure device.

- Underexpansion of transcatheter heart valves and the surgically implanted Perceval sutureless aortic valve bioprosthesis has been suggested as an underlying mechanism for hypo-attenuated leaflet thickening (HALT). This was a single-center prospective observational study that included 47 patients who underwent surgical aortic valve replacement with the Perceval sutureless bioprosthesis (LivaNova, London, United Kingdom) from 2012 to 2016 and were studied by four-dimensional cardiac computed tomography (CT). The association between overall and regional expansion and the prevalence of HALT was analyzed. In total 46 patients were included in the analysis. HALT was found in 39.1% of patients and the mean overall prosthesis expansion was 75.5 ± 5.2% (range 64.6–84.8%). Overall expansion did not differ between patients with HALT compared with patients without HALT (mean overall expansion 74.0 ± 5.2% vs. 76.5 ± 5.0%, P = 0.11). The prevalence of HALT was lower in patients with overall expansion > 80% compared to patients with expansion < 80% expansion though not significantly (20% vs. 44.4%, P = 0.16). None or trivial regional underexpansion was found in 94.7% of coronary cusps. There was no significant association between regional underexpansion and the prevalence of HALT (mean coronary cusp angle 120 ± 8° vs. 119 ± 10°, P = 0.53). The prevalence of HALT and overall underexpansion was high in the Perceval sutureless bioprosthetic valve. Overall underexpansion was not associated with HALT. Whether severe overall underexpansion increases the risk for HALT requires further study. Regional underexpansion was uncommon in the Perceval sutureless bioprosthetic valve and not associated with HALT.Clinical trial registration Unique identifier: NCT03753126 (http://www.clinicaltrials.gov).
