Infective endocarditis after transcatheter approach versus surgical pulmonary valve replacement: A meta-analysis.

Background: In this meta-analysis, we aimed to assess the risk of infective endocarditis in transcatheter versus surgical pulmonary valve replacement patients. Methods: We systematically searched PubMed, Cochrane, EMBASE, Scopus, and Web of Science for the studies that reported the event rate of infective endocarditis in both transcatheter and surgical pulmonary valve replacement between December 2012 and December 2021. Random-effects model was used in the meta-analysis. Results: Fifteen comparison groups with 4,706 patients were included. The mean follow-up was 38.5±3.7 months. Patients with transcatheter pulmonary valve replacement had a higher risk of infective endocarditis than patients receiving surgically replaced valves (OR 2.68, 95% CI: 1.83-3.93, p<0.00001). The calculated absolute risk difference was 0.03 (95% CI: 0.01-0.05), indicating that if 1,000 patients received a surgical valve replacement, 30 cases of infective endocarditis would be prevented. A meta-regression of follow-up time on the incidence of infective endocarditis was not statistically significant (p=0.753). Conclusion: Although transcatheter pulmonary valve replacement is a feasible alternative to surgical replacement in severe right ventricular outflow tract dysfunction, the higher incidence of infective endocarditis in transcatheter replacement remains a significant concern. Regarding this analysis, surgical treatment of right ventricular outflow tract dysfunction is still a viable option in patients with prohibitive risk.

Transcatheter Tricuspid Valve Replacement for Tricuspid Regurgitation: A Systematic Review and Meta-analysis.

BACKGROUND: The present data aim to evaluate the feasibility of the orthotopic trans- catheter tricuspid valve replacement devices, echocardiographic, functional improve- ments, and mortality rates following replacement in patients with significant tricuspid valve regurgitation. METHODS: We systematically searched for the studies evaluating the efficacy and safety of transcatheter tricuspid valve replacement for significant tricuspid valve regurgitation. The efficacy and safety outcomes were the improvements in New York Heart Association functional class, 6-minute walking distance, all-cause death, and periprocedural andlong-term complications. In addition, a random-effect meta-analysis was performed comparing outcomes before and after transcatheter tricuspid valve replacement. RESULTS: Nine studies with 321 patients were included. The mean age was 75.8 years, and the mean European System for Cardiac Operative Risk Evaluation II score was 8.2% (95% CI: 6.1 to 10.3). Severe, massive, and torrential tricuspid valve regurgitation was diagnosed in 95% of patients (95% CI: 89% to 98%), and 83% (95% CI: 73% to 90%) of patients were in New York Heart Association functional class III or IV. At a weighted mean follow-up of 122 days, New York Heart Association functional class (risk ratio = 0.20; 95% CI: 0.11 to 0.35; P < .001) and 6-minute walking distance (mean difference = 91.1 m; 95% CI: 37.3 to 144.9 m; P < .001) significantly improved, and similarly, the prevalence of severe or greater tri- cuspid valve regurgitation was significantly reduced after transcatheter tricuspid valve replacement (baseline risk ratio = 0.19; 95% CI: 0.10 to 0.36; P < .001). In total, 28 patients (10%; 95% CI: 6% to 17%) had died. Pooled analyses demonstrated non-significant differ- ences in hospital and 30-day mortality and >30-day mortality than predicted operative mortality (risk ratio = 1.03; 95% CI: 0.41 to 2.59; P = .95, risk ratio = 1.39; 95% CI: 0.69 to 2.81; P = .35, respectively). CONCLUSION: Transcatheter tricuspid valve replacement could be an emerging treatment option for patients with severe tricuspid regurgitation who are not eligible for transcath-eter repair or surgical replacement because of high surgical risk and poor prognosis.

Decrease of left ventricular ejection fraction in severe illness patients due to COVID-19 may improve as the disease resolves

Background/aim: Increase in publications supporting myocardial involvement in the COVID-19 disease has led to need to gain insight into the the global burden of heart failure after pandemic. We examined the course of myocardial systolic function in patients without elevated troponin levels. Materials and methods: We performed a prospective study. Patients with high troponin levels were excluded from the study in order to definitively exclude complications known to cause permanent left ventricular systolic dysfunction, such as acute coronary syndromes. Two echocardiographic examinations were performed. The first evaluation was performed within the days of hospitalization, if possible, on the day when dyspnea is severe. The second evaluation was performed during the outpatient clinic controls one month after the patient was recovered. Left ventricular ejection fraction (LVEF) was measured using the biplane method of disks (modified Simpson's rule). Results: In the first evaluation, LVEF was found to be significantly lower in the severe illness group than mild/moderate illness group (50 ± 6% and 59 ± 6%; p = 0.03). LVEF decrease (<50%) was found in fifteen patients (43 ± 4%) and detected as global hypokinesia but not segmental. All of these patients were in the severe illness group. In the second evaluation, LVEFs of the fifteen patients with decreased LVEF in the first evaluation were improved and detected in normal limits (first evaluation = 43 ± 4% and second evaluation = 55 ± 2%, p = 0.01). Conclusion: Considering patients without elevated troponin levels during COVID-19 infection, no permanent systolic dysfunction was detected after first month of recovery. We found that transient myocardial dysfunction may develop in the severe illness group with normal troponin levels, LVEF may decrease in the acute phase and improve with the recovery period.

Is high level of hemoglobin A1C an indicator for extended period of antibiotherapy in diabetic foot ulcers?

OBJECTIVE: Diabetic foot ulcers are the most common cause of hospitalization among the diabetic complications. Hemoglobin A1C (HbA1C) has a critical role in medical follow-up of diabetic patients. In fact, the role of HbA1C and related clinical parameters has been investigated in literature there are only a few studies investigating the relationship between HbA1C and the prolonged antibiotherapy. We aim to reveal the reciprocal relationship between this two parameters. METHODS: The clinical data of 139 patients who admitted with diabetic foot ulcers are analyzed retrospectively. Besides the demographic information, the levels of HbA1C wound localizations, the degree of the wounds regarding the Wagner classification, culture antibiogram, and the duration of the antibiotic agents. The data have been analyzed with IBM SPSS Statistics (IBM Statistical Package for the Social Sciences) for Windows 22.0. RESULTS: The clinical data of the 139 diabetic foot patients are retrospectively assessed. The mean age was 56.50 (±4.12). There were 81 male (58.27%) and 58 (41.73%) female patients. The distal type diabetic foot ulcers were found to be the most frequent type (n=83, 59.71% [±3.12]). The mean HbA1C level was 9.60 (±1.10). The "7-15%" subgroups of HbA1C level patients showed statistically significant prolongation of the antibiotherapy time (p<0.01). CONCLUSION: The results showed that the higher levels of HbA1C have a significant effect on treatment duration and formation of deeper and larger wounds with advanced stages of Wagner classification. This result may reveal the importance of the exact starting time of the treatment besides the proper glycemic control. Lager scaled studies may clarify the credited parameters related to diabetic foot ulcers for a reinterpretation of the issue.
