Long-term outcomes following mitral valve replacement in children at heart center Leipzig: a 20-year analysis.

BACKGROUND: Although mitral valve repair is the preferred surgical strategy in children with mitral valve disease, there are cases of irreparable severe dysplastic valves that require mitral valve replacement. The aim of this study is to analyze long-term outcomes following mitral valve replacement in children in a tertiary referral center. METHODS: A total of 41 consecutive patients underwent mitral valve replacement between February 2001 and February 2021. The study data was prospectively collected and retrospectively analyzed. Primary outcomes were in-hospital mortality, long-term survival, and long-term freedom from reoperation. RESULTS: Median age at operation was 23 months (IQR 5-93), median weight was 11.3 kg (IQR 4.8-19.4 kg). One (2.4%) patient died within the first 30 postoperative days. In-hospital mortality was 4.9%. Four (9.8%) patients required re-exploration for bleeding, and 2 (4.9%) patients needed extracorporeal life support. Median follow-up was 11 years (IQR 11 months - 16 years). Long-term freedom from re-operation after 1, 5, 10 and 15 years was 97.1%, 93.7%, 61.8% and 42.5%, respectively. Long-term survival after 1, 5, 10 and 15 years was 89.9%, 87%, 87% and 80.8%, respectively. CONCLUSION: If MV repair is not feasible, MV replacement offers a good surgical alternative for pediatric patients with MV disease. It provides good early- and long-term outcomes.

Early and long-term outcomes following redo mitral valve surgery in patients with prior minimally invasive mitral valve surgery.

OBJECTIVES: The frequency of minimally invasive mitral valve surgery (MVS) has steadily increased over the last decades and therefore surgeons are now encountering an increasing number of patients requiring mitral valve (MV) reoperations post-minimally invasive MVS. The aim of this study was to analyse the early postoperative outcomes and the long-term survival in patients who undergo reoperative MVS following previous minimally invasive surgery. METHODS: Patients who underwent redo MVS following prior minimally invasive MVS between January 2002 and December 2021 were included in our analysis. Study data were prospectively collected and retrospectively analysed. The primary outcomes were 30-day mortality and long-term survival. RESULTS: Among the 187 included patients, 34 (18.2%) underwent repeat MV repair and 153 (81.8%) MV replacement. The median age was 66 years (interquartile range 56-74) and 80 (42.8%) patients were female. Redo MVS was performed through median sternotomy in 169 patients (90.4%). A total of 77 (41.2%) patients had additional concomitant procedures. The median intensive care unit stay was 1 day (1-5). The 30-day mortality was 6.4% (12/187). Estimated survival at 5 and 12 years was 61.8% and 38.3%, respectively. Preoperative stroke (hazard ratio 3.28, 95% confidence interval 1.37-7.85, P = 0.007) as well as infective endocarditis (hazard ratio 1.85; 95% confidence interval 1.09-3.11, P = 0.021) were independent predictors of long-term mortality. CONCLUSIONS: Redo MVS following prior minimally invasive MVS can be performed safely with low early perioperative mortality and acceptable long-term survival. Preoperative stroke, infective endocarditis and concomitant tricuspid valve surgery are independent predictors of long-term mortality.

Mid-term outcomes following the Hemi-Commando procedure for complex infective endocarditis involving the aortomitral junction.

OBJECTIVES: Perivalvular abscesses with destruction of the aortomitral junction (AMJ) are a severe complication of infective endocarditis (IE) and are associated with high mortality and complex management. The Hemi-Commando procedure is a mitral valve-sparing alternative to the Commando procedure in suitable patients with complex IE and paravalvular destruction. This study reviews the mid-term outcomes in patients undergoing the Hemi-Commando procedure for treating IE with destruction of the AMJ. METHODS: The clinical outcomes of patients with IE and AMJ involvement who underwent the Hemi-Commando procedure between 2015 and 2021 at the Leipzig Heart Center were retrospectively analysed. Primary outcomes were 30-day mortality and 1-year survival. Secondary outcome was 1-year freedom from reoperation. RESULTS: A total of 22 patients underwent the Hemi-Commando procedure during the study period. The patients' mean age was 59.8 ± 18.3 years. The study population was predominantly male (86.4%). Preoperative sepsis was present in 6 (27.3%) patients, and the median EuroSCORE II was 28.5%. Almost two-thirds (N = 14; 63.6%) of the patients presented with native IE. Streptococci were the most common pathogens (N = 8; 36.4%). Paravalvular abscess was found intraoperatively in 16 (72.7%) patients. The 30-day mortality was 13.6%. The estimated 1- and 3-year survival rates were 77.5% and 66.4%, respectively. The estimated freedom from reoperation at 1 and 3 years was 92.3%. CONCLUSIONS: The Hemi-Commando procedure offers an acceptable mid-term survival chance with low reoperation rates and is, therefore, a reasonable mitral valve-sparing alternative to the Commando procedure in suitable patients with extensive IE and perivalvular involvement.

Síndrome de burnout y justicia organizacional: una revisión sistemática / Burnout syndrome and organizational justice: a systematic review

Se tuvo como objetivo analizar sistemáticamente las publicaciones que abordan la relación entre la justicia organizacional y el síndrome de burnout en diferentes poblaciones laborales. La aproximación se efectuó a partir de una revisión sistemática de la literatura científica en Scopus, Pubmed, Cochrane; Science Direct y Lilacs de artículos observacionales que evaluaran la relación entre el constructo de justicia organizacional y la presencia de síndrome de burnout. Resultados: se incluyeron 21 artículos en la síntesis cualitativa que analizaban la relación directa entre la justicia organizacional y el síndrome de burnout. Con excepción de uno, todos los artículos analizados reportan una correlación negativa entre la percepción de justicia organizacional y la presencia del síndrome de burnout. Igualmente, se observó que todas las dimensiones de justicia se correlacionaron negativamente tanto con el síndrome visto en forma global o sus dimensiones, solamente el logro personal y el compromiso con el trabajo se relacionaron positivamente con la percepción de justicia. Conclusión: dada la consistente correlación negativa encontrada en los estudios analizados, es necesario dar más relevancia al papel de la justicia organizacional en la aparición o presencia del síndrome, igualmente este aspecto debe ser tenido en cuenta en la formulación de estrategias de intervención(AU)

Objective: To systematically analyse the literature addressing the relationship between organizational justice and burnout syndrome in different working populations. Methods: We conducted a systematic review of the scientific literature contained in Scopus, Pubmed, Cochrane; Science Direct and LILACS of observational studies evaluating the relationship between the organizational justice construct and the presence of burnout syndrome. Results: Twenty-one articles were included in the qualitative synthesis. All but one of the included articles reported a negative correlation between the perception of organizational justice and the presence of burnout syndrome. Likewise, all dimensions of justice were negatively correlated with burnout, both globally as well as with each of its dimensions. Only personal achievement and commitment to work were positively associated with the perception of justice. Conclusion: Given the consistent negative correlation found in the studies analyzed, it is necessary to give more importance to the role of organizational justice in the emergence or presence of the syndrome; this aspect should also be considered when formulating intervention strategies(AU)
