Purpose: This study aimed to determine the prevalence of hypomineralised second primary molars (HSPM) and molar incisor hypomineralisation (MIH) in cleft lip and/or palate (CL/P) patients.

Methods: A retrospective analysis of intraoral photographs of CL/P patients was done. All patients born between 2000 and 2011, and visiting the cleft team of the Erasmus Medical Center in Rotterdam, The Netherlands, were included.

A novel cardioprotective perfusion protocol prevents functional decline during extended normothermic ex situ heart perfusion of marginal porcine hearts.

Background: A common limitation to normothermic ex situ heart perfusion (ESHP) is functional decline. We previously designed a cardioprotective normothermic perfusion protocol, incorporating adenosine-lidocaine cardioplegia, subnormothermic reperfusion, pyruvate and methylprednisolone supplementation, and hemofiltration to prevent myocardial functional decline over 4 hours. In this study, we added continuous catecholamine infusion and protective loading conditions to assess the effectiveness of this enhanced cardioprotective perfusion protocol in preventing functional decline during extended normothermic perfusion in marginal porcine hearts.

Case Report: Optimal utilization of marginal lung allografts by considering donor-recipient PGD risk compatibility and by mitigating allograft and recipient inflammatory risk.

Reducing the risk of high-grade primary graft dysfunction (PGD) is vital to achieve acceptable short- and long-term outcomes for recipients following lung transplantation. However, the utilization of injured lung allografts, which may confer a higher risk of PGD, must be considered due to the disparity between the increasing number of patients requiring lung transplantation and the limited donor pool. We describe a case in which highly marginal lung allografts were utilized with a good post-transplant outcome.

Echocardiographic and Clinical Outcomes of Concomitant Secondary Chordal Cutting to Surgical Myectomy in Hypertrophic Obstructive Cardiomyopathy: A Systematic Review and Meta-analysis.

In patients who underwent surgical myectomy for hypertrophic obstructive cardiomyopathy (HOCM), additional mitral valve repair may offer additional benefits in terms of further reducing left ventricular outflow tract (LVOT) gradients, systolic anterior motion (SAM), and mitral regurgitation (MR). We performed a systematic review of the literature to evaluate the evidence of surgical myectomy with additional secondary chordal cutting in patients with HOCM. A systematic literature search in MEDLINE and EMBASE was performed until April 2024.

Past Trends and Future Directions of Cardiac Regenerative Medicine - A Systematic Analysis of Clinical Trial Registries.

Cell therapy, gene therapy, and tissue engineering have been explored as potential strategies to repair or regenerate damaged cardiac tissue. Despite the presence of encouraging preclinical data, clinical trials of regenerative cardiac therapies have yielded mixed results. Our study aimed to investigate the fate of all registered clinical trials within regenerative cardiac medicine, with the purpose of exploring the potential role of publication bias (or trial-completion bias), how published and unpublished research affects the field, and to draw lessons and recommendations for future clinical trials.

Cost Analysis of Robot-Assisted Versus On-Pump and Off-Pump Coronary Artery Bypass Grafting: A Single-Center Surgical and 30-Day Outcomes Comparison.

Objective: Throughout Europe, the interest in implementing robot-assisted minimally invasive direct coronary artery bypass (RA-MIDCAB) has been growing. However, concerns about additional costs have emerged concurrently. In this analysis, we aim to provide a comparison of the cumulative perioperative costs of RA-MIDCAB, on-pump coronary artery bypass grafting (CABG), and off-pump CABG (OPCAB).

Outcome after left ventricular assist device exchange.

Objectives: Left ventricular assist device (LVAD) therapy has evolved from a short-term bridge-to-transplant strategy into a long-term and often chronic therapy due to long waiting times for heart transplantation and application as destination therapy. Consequently, patients are at risk of developing complications necessitating LVAD exchange. The aim of this study is to assess patient outcomes after LVAD exchange.

Mitigating the risk of inflammatory type primary graft dysfunction by applying an integrated approach to assess, modify and match risk factors in lung transplantation.

Long-term outcome following lung transplantation remains one of the poorest of all solid organ transplants with a 1- and 5-year survival of 85% and 59% respectively for adult lung transplant recipients and with 50% of patients developing chronic lung allograft dysfunction (CLAD) in the first 5 years following transplant. Reducing the risk of inflammatory type primary graft dysfunction (PGD) is vital for improving both short-term survival following lung transplantation and long-term outcome due to the association of early inflammatory-mediated damage to the allograft and the risk of CLAD. PGD has a multifactorial aetiology and high-grade inflammatory-type PGD is the result of cumulative insults that may be incurred in one or more of the three variables of the transplantation continuum: the donor lungs, the recipient and intraoperative process.

Use of virtual reality in preoperative education of cardiac surgery patients - A feasibility study.

Objective: A Virtual Patient Tour (VPT) was developed to inform cardiac surgery patients about their hospitalization from the admission to their postoperative stay on the ward. The objective of our study was to assess the feasibility and acceptability of this VPT following the framework of the Virtual Reality Clinical Outcomes Research Experts Committee.

Methods: In this single-centre cross-sectional study, adult patients admitted to the hospital for elective cardiac surgery were included.

Left Ventricular Pressure-Volume Loop Analyses for Donor Hearts: Proof of Concept in an Ovine Experimental Model.

heart perfusion (ESHP) has emerged as an important strategy to preserve donation after brain death (DBD) and donation after circulatory death (DCD) donor hearts. Clinically, both DBD and DCD hearts are successfully preserved using ESHP. Viability assessment is currently based on biochemical values, while a reliable method for graft function assessment in a physiologic working mode is unavailable.

First-time surgical aortic valve replacement: nationwide trends and outcomes from The Netherlands Heart Registration.

Objectives: The aim of this study was to describe trends and outcomes for patients undergoing surgical aortic valve replacement (SAVR) in the Netherlands.

Methods: The Netherlands Heart Registration database was used to report the number and outcomes of isolated, primary SAVR procedures performed from 2007 to 2018 in adult patients.

Results: A total of 17 142 procedures were included, of which 77.

Monitoring left ventricular assist device parameters to detect flow- and power-impacting complications: a proof of concept.

Aims: The number of patients on left ventricular assist device (LVAD) support increases due to the growing number of patients with end-stage heart failure and the limited number of donor hearts. Despite improving survival rates, patients frequently suffer from adverse events such as cardiac arrhythmia and major bleeding. Telemonitoring is a potentially powerful tool to early detect deteriorations and may further improve outcome after LVAD implantation.

Gene therapy during heart perfusion: a new frontier in cardiac regenerative medicine?

organ preservation by machine perfusion can improve preservation of organs for transplantation. Furthermore, machine perfusion opens up the possibilities for selective immunomodulation, creation of tolerance to ischemia-reperfusion injury and/or correction of a pathogenic genetic defect. The application of gene modifying therapies to treat heart diseases caused by pathogenic mutations during heart perfusion seems promising, especially given the limitations related to delivery of vectors that were encountered during clinical trials using cardiac gene therapy.

Hemofiltration Improves Blood Perfusate Conditions Leading to Improved Ex Situ Heart Perfusion.

The aim was to optimize the perfusate composition by including a hemofiltrator to the PhysioHeartplatform for ex situ heart perfusion of porcine slaughterhouse hearts. Fourteen hearts were harvested from Dutch Landrace pigs and slaughtered for human consumption. All hearts were preserved for 4 hours using static cold storage before reperfusion for 4 hours on the PhysioHeart platform.

Successful aortic arch cannulation and perfusion of a heart donated after circulatory death: A case report.

Introduction: We describe successful aortic arch cannulation and perfusion of a heart donated after circulatory death using the Transmedics Organ Care System™.

Case Report: A 47-year old man developed advanced heart failure symptoms after prior mustard operation for transposition of the great arteries. He matched a DCD-donor and required an elongated aorta for implantation due to his altered anatomy.

Circadian rhythms in pump parameters of patients on contemporary left ventricular assist device support.

Background: Algorithms to monitor pump parameters are needed to further improve outcomes after left ventricular assist device (LVAD) implantation. Previous research showed a restored circadian rhythm in pump parameters in patients on HeartWare (HVAD) support. Circadian patterns in HeartMate3 (HM3) were not studied before, but this is important for the development of LVAD monitoring algorithms.

Pre-Operative SARS-CoV-2 Testing in Asymptomatic Heart Transplantation Recipients.

Introduction: From the start of the coronavirus disease 2019 (COVID-19) pandemic, international guidelines have recommended pre-operative screening for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) before heart transplantation (HTx). Due to the changing prevalence of COVID-19, the chances of false positive results have increased. Because of increased immunity in the population and evolution of SARS-CoV-2 to current Omicron variants, associated mortality and morbidity have decreased.

Surgical treatment of esophago-tracheobronchial fistulas after esophagectomy.

The aim of this study was to evaluate the surgical treatment of esophago-tracheobronchial fistulas (ETBFs) that occurred after esophagectomy with gastric conduit reconstruction in a tertiary referral center for esophageal surgery. All patients who underwent surgical repair for an ETBF after esophagectomy with gastric conduit reconstruction were included in a tertiary referral center. The primary outcome was successful recovery after surgical treatment for ETBF, defined as a patent airway at 90 days after the surgical fistula repair.

Dilemmas concerning heart procurement in controlled donation after circulatory death.

With an expanding population at risk for heart failure and the resulting increase in patients admitted to the waiting list for heart transplantation, the demand of viable organs exceeds the supply of suitable donor hearts. Use of hearts after circulatory death has reduced this deficit. Two primary techniques for heart procurement in circulatory death donors have been described: direct procurement and perfusion and thoraco-abdominal normothermic regional perfusion.

Cold Oxygenated Machine Perfusion Improves Functional Survival of Slaughterhouse Porcine Hearts.

The aim of our study was to explore the effect of cold oxygenated machine perfusion in slaughterhouse porcine hearts on functional myocardial survival compared to static cold storage (SCS). Seventeen hearts were harvested from Dutch Landrace Hybrid pigs, which were sacrificed for human consumption and randomly assigned to the 4 hours SCS group (N = 10) or the 4 hours cold oxygenated machine perfusion group (N = 7). Hearts were perfused with a homemade Heart Solution with a perfusion pressure of 20-25 mm Hg to achieve a coronary flow between 100 and 200 ml/minute.

Ventilation during ex vivo lung perfusion, a review.

Evidence suggests that ventilation during ex vivo lung perfusion (EVLP) with a 'one-size-fits-all' strategy has the potential to cause lung injury which may only become clinically relevant in marginal lung allografts. EVLP induced- or accelerated lung injury is a dynamic and cumulative process reflecting the interplay of a number of factors. Stress and strain in lung tissue caused by positive pressure ventilation may be exacerbated by the altered properties of lung tissue in an EVLP setting.

A case series of wind instrument players with cleft lip and/or palate.

It might be more difficult for patients with cleft lip and/or palate (CL/P) to generate sufficient muscle tension of the upper lip and intraoral air pressure to play a wind instrument. We aimed to explore and describe the key aspects of wind instrument playing with a repaired cleft. An in-depth interview was conducted among ten patients with CL/P and one with a functionally comparable problem and we found that: individuals with CL/P can achieve a professional level on a wind instrument; the oboe and trumpet may be less suitable for patients with CL/P because of the high lip muscle tension and intraoral air pressure that must be generated; air leakage through a fistula, unrepaired alveolus or velopharyngeal insufficiency can be troublesome; and for people with CL/P, a brass instrument with a large mouthpiece is easier than a small mouthpiece.
