Peak Exercise

Context:It is more feasible to assess functional capacity with an exercise test than to measure peak-exercise VO2.Objective:To assess whether maximal workload reliably predicts peak VO2.Patients:Thirty-six patients after aortic-valve replacement during routine follow-up.Design:Incremental symptom-limited cycle exercise test in the upright position with increments of 20 W/min.Setting:Out-clinic patients, university hospital.Main Outcome Measures:Maximal workload, ventilatory threshold, and peak VO2.Results:Maximal workload was 151 ± 39 W, and peak VO2, 1649 ± 486 ml/min. The correlation coefficient between maximal workload and peak VO2wasr= .92 (P< .0001). The regression equation for the estimation of peak VO2wasy= 11.7 (maximal workload in watts) – 110.7. Peak VO2calculated with this equation was 1657 ± 451 ml/min.Conclusions:Maximal workload during ergometry in the upright position reliably predicted peak VO2.

Qualitative Interview Study

ObjectivesSleep disturbances and delirium are frequently observed complications after surgical aortic valve replacement (SAVR) and transcutaneous aortic valve implantation (TAVI), especially in octogenarian patients. However, a knowledge gap exists on patient experiences of sleep and delirium. In particular, patients’ long-term sleep and delirium experiences are unknown. This article explores and describes how octogenarian patients suffering from delirium after aortic valve replacement experience their sleep and delirium situation.DesignAn explorative and descriptive design with a longitudinal qualitative approach was applied. Qualitative content analysis following the recommended steps of Graneheim and Lundman was performed.SettingPatients were included at a tertiary university hospital with 1400 beds. Delirium and insomnia screening was performed at baseline and five postoperative days after aortic valve treatment. For qualitative data, 10 patients were interviewed 6–12 months after treatment with focus on delirium. Five of these patients were reinterviewed 4 years after treatment, with focus on their sleep situation.ParticipantsInclusion criteria; age 80+, treated with SAVR or TAVI and had experienced delirium after treatment.ResultsFor the initial interview, we included five men and five women, four following TAVI and six following SAVR, mean age 83. One overarching theme revealed from the content analyses; Hours in bed represented emotional chaos. Whereas three subthemes described the patients’ experiences with sleep and delirium, a cascade of distressful experiences disturbing sleep, the struggle between sleep and activity and elements influencing sleep. Four years after the treatment, sleep disturbances persisted, and patients still remembered strongly the delirium incidences.ConclusionsFor octogenarian patients, sleep disturbances and delirium are long-term burdens and need a greater attention in order to improve patient care.

Valve Pathology

Background: Aortic valve stenosis is the most frequent cardiac valve pathology in the western world. In the last few years, sutureless valves have been strongly developed with a lot of applications. The aim of this study was to evaluate the feasibility, mid-term outcomes of sutureless aortic valve replacement technique. Subjects and methods: 13 patients who underwent sutureless aortic valve replacement between 12/2015 to 05/2018 at Clermont – Ferrand University Hospital, France. Descriptive study, postoperative follow-up, clinical evaluation, and echocardiography. Results: mean cross-clamp time was 84.8 ± 22.9 min, mean cardiopulmonary bypass time was 113.4 ± 21.2 min. Improved mean preoperative and postoperative aortic gradients: 40.3 ± 17.4 mmHg versus 10.5 ± 4.8 mmHg (1 month) and 12.0 ± 4.5 mmHg (6 months). Mean intensive care unit stay was 7.8 ± 11.8 days, mean hospital stay was 23.2 ± 15.5 days. No case of death was reported after 6 months. Conclusion: sutureless aortic valve replacement technique is feasible, with good short-term and mid-term outcomes, improve hemodynamics, can be applied in intermediate and high-risk patients.

A Prospective Study

Background: Previous cardiac operations may complicate mitral valve exposure, as adhesions and loss of mobility in the surrounding tissues may be present. In such cases, the conventional left atrial (LA) incision may not offer satisfactory visualization in the surgical site of the valve. Therefore, several alternative approaches have been proposed for satisfactory visualization of the mitral valve intraoperatively.Aim of the work: to evaluate the outcome of the transseptal and transatrial approaches for mitral valve replacement in patients undergoing redo mitral valve surgery.Patients and Method: This is a prospective study that was conducted at Cardio-thoracic surgery department of Al-Azhar University hospital (Damietta) and other centers during the period from the January 2018 to May 2019. It included 30 patients undergoing redo mitral valve surgery; 15 of them had transseptal approach and 15 with transatrial approach.Results: Age was comparable between studied groups. There was 6 males (40.0%) in group I and 7 males (46.7%) in group II. Smoking was reported in 8 (53.3%) in group I and 7 (46.7%) in group II. Hypertension and pulmonary disease were reported in 6 (40.0%) versus 7 (46.7%) and 2 (13.3%) versus 3 (20.0%) in groups I and II respectively. Diabetes mellitus was reported in 9 (60.0%) in group I versus 4 (26.7%) in group II. Finally, there was no significant difference between both approaches as regard to intraoperative or postoperative data.Conclusion: Transatrial approach has been used in most of previous studies; the transseptal approach appears to be equally effective.

IntroductionCytokine storm and endotoxin release during cardiac surgery with cardiopulmonary bypass (CPB) have been related to vasoplegic shock and organ dysfunction. We hypothesised that early (during CPB) cytokine adsorption with oXiris membrane for patients at high risk of inflammatory syndrome following cardiac surgery may improve microcirculation, endothelial function and outcomes.Methods and analysisThe Oxicard trial is a prospective, monocentric trial, randomising 70 patients scheduled for cardiac surgery. The inclusion criterion is patients aged more than 18 years old undergoing elective cardiac surgery under CPB with an expected CPB time >90 min (double valve replacement or valve replacement plus coronary arterial bypass graft). Patients will be allocated to the intervention group (n=35) or the control group (n=35). In the intervention group, oXiris membrane will be used on the Prismaflex device (Baxter) at blood pump flow of 450 mL/min during cardiac surgery under CPB. In the control group, cardiac surgery under CPB will be conducted as usual without oXiris membrane. An intention-to-treat analysis will be performed. The primary endpoint will be the microcirculatory flow index measured by sublingual microcirculation device at day 1 following cardiac surgery. The secondary endpoints will be other microcirculation variables at CPB end, 6 hours after CPB, at day 1 and at day 2. We also aim to evaluate the occurrence of major cardiovascular and cerebral events (eg, myocardial infarction, stroke, ischaemic mesenteric, resuscitated cardiac arrest, acute kidney injury) within the first 30 days. Cumulative catecholamine use, intensive care unit length of stay, endothelium glycocalyx shedding parameters (syndecan-1, heparan-sulfate and hyaluronic acid), inflammatory cytokines (tumour necrosis factor (TNF) alpha, interleukin 1 (IL1) beta, IL 10, IL 6, lipopolysaccharide, endothelin) and endothelial permeability biomarkers (angiopoietin 1, angiopoietin 2, Tie2 soluble receptor and Vascular Endothelial Growth Factor (VEGF) will also be evaluated.Ethics and disseminationEthical approval has been obtained from the Institutional Review Board of the University Hospital of Amiens (registration number ID RDB: 2019-A02437-50 in February 2020). Results of the study will be disseminated via peer-reviewed publications and presentations at national and international conferences.Trial registration numberNCT04201119.

Morphological Patterns

Recently, the functional aspect as well as morphological aspect of the reserve cells in the cervix uteri drew much attention in view of the carcinogenesis in squamocolumunar junction. In this communication, the authors elucidate the ultrastructural features of the reserve cells in patients of various age groups visiting our university hospital and affiliated hospital.From conventional light microscopic point of view, the reserve cells tend to be pronounced in various pathological conditions, such as the persisting inflammation, proliferative disorders and irritation of hormones. The morphological patterns of the reserve cells from various stage and degree of irritation were observed.
