Aortic root replacement with a composite mechanical valve graft (Bentall procedure) has been a recommended strategy in patients with aortic root aneurysm with or without aortic regurgitation. Aortic root remodeling (Yacoub procedure) has emerged as a valve-sparing alternative although there is only scarce multicenter evidence.

Using propensity-score matching, we compared all the patients undergoing the Bentall procedure in the Czech Republic between 2010 and 2021 with patients after the Yacoub procedure from four experienced centers. <i>Results</i>. During the study period, 199 patients underwent Yacoub and 526 had Bentall procedure. Of those, 166 pairs were selected and compared.

The Impella 5.5 offers a less invasive transvalvular approach to left ventricular mechanical support. End-organ recovery and hemolysis have been well-studied with durable left ventricular assist devices but effects of Impella 5.5 on these parameters are less well described. <i>Methods</i>. All Impella 5.5 recipients between August 2020 and June 2023 were reviewed from a single institution. Hemodynamics and laboratory values were compared between preimplant and prior to device removal. Hemolysis was defined as postoperative lactate dehydrogenase &gt;1000 IU/L with concurrent plasma-free hemoglobin &gt;50 mg/dL. Paired Wilcoxon tests compared the median of differences between preimplant and pre-explant values. <i>Results</i>. We studied 127 consecutive implants of the Impella 5.5. Thirty-one patients had concomitant VA-ECMO, and one received Impella 5.5 after durable LVAD explant; these cases were excluded. Our final cohort included 95 patients, with an average age of 55.29 ± 14.5 years. Median implant duration was 11 days (IQR:6–16 days). To avoid confounding hemodynamic factors, we restricted hemodynamic analysis to the 37 patients who received isolated Impella 5.5, excluding those with prior IABP, Impella CP, acute MI, or prior cardiac surgery. These patients experienced improvements from baseline in pulmonary vascular resistance (−77.03 dynes/sec/cm⁻⁵, <i>p</i> &lt; 0.01) and wedge pressure (−6.5 mmHg, <i>p</i> &lt; 0.01).

Previous research has only conducted a restricted amount of investigations on the effectiveness of propafenone in preventing and treating of atrial fibrillation (AF) after cardiac surgery.

A meta-analysis of randomized controlled trials was conducted. Until September 15th, 2023, various databases were searched. The main focal points consisted of the presence of POAF, transition from AF to sinus rhythm, and reappearance of AF. The odds ratios (ORs) for treatment effects on dichotomous variables were calculated. <i>Results</i>. The analysis of data included 9 controlled trials that were randomized and had 1014 patients.

Surgical mobilization of the internal mammary artery (IMA) can induce graft vasospasm, which is commonly managed by wrapping the IMA in a vasodilator-soaked swab before grafting. However, the choice of the most effective topical vasodilator remains the subject of continued investigation. We carried out a prospective randomized controlled trial to compare the effect of topically applied milrinone, nitroglycerin, and normal saline on IMA free flow. <i>Methods</i>. Forty-six consecutive patients undergoing elective primary coronary artery bypass grafting were enrolled. After the left IMA was harvested, free flow was measured under controlled hemodynamic conditions before any intervention (flow 1) and at a mean of 12.5 minutes after the topical application of one of three agents (milrinone, nitroglycerin, or normal saline) on the IMA (flow 2). <i>Results</i>. All agents induced a significant increase in IMA flow, and flow 2 was significantly higher in the nitroglycerin and milrinone groups compared to the normal saline group, even while controlling for flow 1 as a centered continuous variable. Nevertheless, there was no statistically significant difference in flow 2 between the nitroglycerin and milrinone groups. <i>Conclusions</i>. Topically applied milrinone and nitroglycerin can increase blood flow of the IMA significantly in the early period after surgical mobilization.

The results of the Fontan operation, depending on the anatomy of the pulmonary arteries, have been studied quite well. Various indices have been proposed to assess the degree of hypoplasia of the pulmonary arterial bed (Nakata, Reddy, and McGoon indexes). At the same time, an obstruction of pulmonary venous blood return may be considered as a contraindication to Fontan operation. <i>Aim of the Study</i>. To present an optimal method for pulmonary venous index (PVI) calculation based on computed tomography angiography (CTA) enhancement of the heart data in patients with a functional single ventricle. <i>Materials and Methods</i>. 63 patients with a functional single ventricle (SV) underwent CTА (Philips, Brilliance iCT) before the Fontan operation. Axial sections were reconstructed to a thickness of 0.75–3 mm using soft tissue and lung filters, followed by postprocessing of the data (Horos and OsiriX software) and construction of multiplanar and 3D images. The diagnoses were presented by various types of SV of the heart. The age of the patients ranged from 3 to 30 years (median 7 years). Comparison of PVI was carried out in patients of two groups: those who survived the intervention (<i>n</i> = 55 patients) and those who died (<i>n</i> = 8). The evaluation of the pulmonary veins (PV) and the calculation of the pulmonary venous index (PVI) were carried out based on the measurement of each pulmonary vein at 2 levels (at the level of the orifices and bifurcation). The calculation of the PVI was carried out according to the formula: the sum of the cross-sectional area of the main pulmonary veins, related to the body surface area. 3 variants of PVI calculation were compared: taking into account the values of the PV areas at the level of the orifices, the bifurcation, and the sum of the minimum areas of each of the PVs. <i>Results</i>. In the group of survived patients, the median PVI at the level of the PV orifices was 292 mm/m², and in the group of deceased, it was 242 mm/m²(<i>p</i> = 0.0326); at the level of PV bifurcation in the group of survivors, it was 299 mm/m², and in the group of dead patients, it was 281 mm/m²(<i>p</i> = 0.0776); the minimum PVI was 257 mm/m² in the survivor group and 218 mm/m² in the deceased group (<i>p</i> = 0.006).

Herein, we investigated the outcomes of VSD closure with or without tricuspid valve detachment and assessed the impact of this technique on postoperative tricuspid valve function and atrioventricular conduction. In total, 175 patients who underwent isolated VSD closure through the right atrium were retrospectively enrolled and divided into 2 groups: the tricuspid valve detachment group (<i>n</i> = 17, 9.7%) and the nontricuspid valve detachment group (<i>n</i> = 158, 90.3%). Patient characteristics were comparable between the two groups, and medical records and echocardiography reports were reviewed for each patient. The primary outcomes were mortality and reoperation, whereas the secondary outcomes included residual VSD, tricuspid valve regurgitation, advanced atrioventricular block, and aortic valve regurgitation. Clinical variables were compared between the two groups. Overall, tricuspid valve detachment did not increase perioperative complications or affect long-term tricuspid valve function. There were no cases of mortality or reoperation in either group. Although the tricuspid valve detachment group had longer bypass and cross-clamp times, this did not significantly affect ventilation or intensive care unit stay duration. Follow-up echocardiography revealed no significant intergroup differences in tricuspid regurgitation, residual shunt, or aortic valve regurgitation. In conclusion, tricuspid valve detachment is a safe and reliable technique for the complete closure of hard-to-expose VSDs without compromising tricuspid valve function. Moreover, it does not increase the risk of adverse events, and its outcomes remain favorable during short- and long-term follow-ups.</p>\u0000 </div>","PeriodicalId":15367,"journal":{"name":"Journal of Cardiac Surgery","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/5280537","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139959833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
