- A modification in Ross operation is described in which the free-standing pulmonary autograft root is suspended in a Dacron prosthetic vascular jacket with a view to prevent dilatation of the neo-aortic root. In a group of 13 patients operated consecutively using this technique, there was no significant increase in the diameters of the neo-aortic root after a mean 16-month follow-up. Aortic valve function remained also satisfactory.

- 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.

- Objective: The present study evaluates the impact of prosthesis-patient mismatch (PPM) on left ventricular remodelling following aortic valve replacement (AVR) for severe aortic insufficiency. Methods: In this study, 230 patients undergoing aortic valve surgery were divided into two groups depending on whether or not they exhibited PPM. Postoperative left ventricular (LV) dimensions and function were compared to the preoperative status. Results: The incidence of PPM (EOAi

- To evaluate the association between statin use after surgical aortic valve replacement for aortic stenosis and long-term risk for major adverse cardiovascular events in a large population-based, nationwide cohort.All patients that underwent isolated surgical aortic valve replacement due to aortic stenosis in Sweden 2006-2020 and survived six months after discharge were included. Individual patient data from five nationwide registries were merged. Primary outcome is major adverse cardiovascular event (defined as all-cause mortality, myocardial infarction, or stroke). Multivariable Cox regression model adjusted for age, sex, comorbidities, valve type, operation year, and secondary prevention medications is used to evaluate the association between time-updated dispense of statins and long-term outcome in the entire study population, and in subgroups based on age, sex and comorbidities.A total of 11,894 patients were included. Statins were dispensed to 49.8% (5918/11894) of patients at baseline, and 51.0% (874/1713) after ten years. At baseline, 3.6% of patients were dispensed low dose, 69.4% medium dose and 27.0% high dose statins. After adjustments, ongoing statin treatment was associated with a reduced risk for major adverse cardiovascular event [adjusted hazard ratio 0.77 (95% confidence interval 0.71-0.83). p < 0.001], mainly driven by a reduction in all-cause mortality [adjusted hazard ratio, 0.70 (0.64-0.76)], p < 0.001. The results were consistent in all subgroups.The results suggest that statin therapy might be beneficial for patients undergoing surgical aortic valve replacement for aortic stenosis. Randomized controlled trials are warranted to establish causality between statin treatment and improved outcome.

- Objective: Vacuum-assisted closure (VAC) is a recently introduced method for the treatment of poststernotomy mediastinitis. The aim was to examine the effects of VAC negative pressure on peristernal soft tissue, blood flow after internal mammary artery harvesting. Methods: Microvascular blood flow was measured using laser Doppler velocimetry in a porcine sternotomy wound model. The effect of VAC negative pressure on blood flow to the wound edge was investigated on the right side, where the internal mammary artery was intact, and on the left side, where the internal mammary artery had been removed. Results: Before removal of the left internal mammary artery, the blood flow was similar in the right and left peristernal wound edges, 2.5 cm from the edge (27 +/- 4 perfusion units (PU) on the right side and 32 +/- 3 PU on the left side, in muscle tissue). When the left internal mammary artery was surgically removed, the blood flow on the left side decreased (19 3 PU, in muscle tissue), while the skin blood flow was not affected. VAC negative pressure induced an immediate increase in wound edge blood flow both on the right side (43 +/- 9 PU, in muscle tissue at -75 mmHg), where the internal mammary artery was intact, and on the left side, where the internal mammary artery had been removed (49 11 PU, in muscle tissue at -75 mmHg). The increase in blood flow was similar on both sides at -75 mmHg and at -125 mmHg. Conclusions: The peristernal wound edge microvascular blood flow is decreased when the left internal mammary artery is removed. VAC therapy stimulates blood flow in the peristernal thoracic wall after internal mammary artery harvesting. (c) 2006 Elsevier B.V. All rights reserved.
