Expanded polytetrafluoroethylene (ePTFE) neochordae are predominantly used for mitral valve repair (MVr), while the frequency of their employment in tricuspid valve surgery is not well assessed. We have performed a review of the available literature to verify incidence, indications, techniques, and outcomes of the use of artificial neochordae in a variety of tricuspid valve pathologies. We found a total of 57 articles reporting the use of ePTFE sutures in patients in whom tricuspid valve repair (TVr) was performed...

OBJECTIVES:  Very precise positioning of the transcatheter heart valve (THV) inside the degenerated SAV is a crucial factor for valve-in-valve (ViV) procedure to achieve optimal hemodynamic results. Therefore, our study aimed to investigate the impact of implantation depth on functional results after ViV procedures in a standardized in vitro setting. METHODS:  THV (SAPIEN 3 Ultra 23-mm size) and three SAV models (Magna Ease, Trifecta, and Hancock II-all 21-mm size) were tested at different circulatory conditions in five different positions of the THV (2-6 mm) inside the SAV...

BACKGROUND: Minimally invasive aortic valve replacement (MiAVR) is an established technique for surgical aortic valve replacement (AVR). Although MiAVR was first described in 1993 and has shown good results compared to full sternotomy AVR (FSAVR) only a minority of patients undergo MiAVR. We recently started using MiAVR via an upper hemisternotomy. We aimed to examine the early results of our initial experience with this technique. METHODS: We compared 55 MiAVR to a historical cohort of 142 isolated FSAVR (12...

The postoperative course of the graft tissue after bronchial stump coverage remains unclear. We retrospectively analyzed 44 patients who underwent anatomical lung resection followed by bronchial stump coverage using free pericardial fat grafts. All patients underwent minimally invasive video-assisted thoracoscopic surgery. Computed tomography scans showed a graft retention rate of 100% on 60 days after surgery, 61% on 180 days, and plateauing at around 20% after one year. Free pericardial fat grafts, harvested minimally invasively, demonstrated a promising retention rate after surgery, making them a suitable option for patients with a high risk of broncho-pleural fistula...

OBJECTIVES:  Mechanisms of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) differ as CABG provides surgical collateralization and may prolong life by preventing future myocardial infarctions (MIs). However, evidence for CABG in patients with chronic total occlusion (CTO) has not been fully elucidated and the impact of PCI is discussed controversially. METHODS:  We performed a meta-analysis of studies comparing outcomes in patients with/without multivessel disease undergoing CABG or PCI for CTO...

Postinfarction left ventricular aneurysm (LVA) still remains a complication after myocardial infarction with a poor prognosis. Its incidence has decreased due to improved treatment, however, it may have experienced a renaissance due to the coronavirus disease 2019 pandemic. In this retrospective, single-center cohort study, we analyzed n  = 17 patients who underwent left ventricular reconstruction after Dor. The results show a mean intensive care unit stay of 8 ± 16 days and a 30-day mortality rate of 6%...

We reviewed the cardiac surgical literature for 2023. PubMed displayed almost 34,000 hits for the search term "cardiac surgery AND 2023." We used a PRISMA approach for a results-oriented summary. Key manuscripts addressed the mid- and long-term effects of invasive treatment options in patient populations with coronary artery disease (CAD), comparing interventional therapy (percutaneous coronary intervention [PCI]) with surgery (coronary artery bypass graft [CABG]). The literature in 2023 again confirmed the excellent long-term outcomes of CABG compared with PCI in patients with left main stenosis, specifically in anatomically complex chronic CAD, but even in elderly patients, generating further support for an infarct-preventative effect as a prognostic mechanism of CABG...

Deep hypothermia helps protect the spinal cord, but is invasive. Here, we present a method to avoid reperfusion injury by selectively circulating cold blood under high pressure to the intercostal artery during reperfusion after intercostal artery reconstruction. Of the 23 patients who underwent thoracoabdominal aortic aneurysm open repair, one died. The motor evoked potential disappeared during aortic clamping in nine patients. Six patients recovered completely from aortic clamping release, two showed recovery >50% and one achieved full recovery three months later...
