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.

Long-term results following atrioventricular septal defect repair.

BACKGROUND: Atrioventricular septal defects (AVSD) represent 4-7% of congenital cardiac malformations. Definitive early repair is favored over prior pulmonary artery banding and delayed definitive repair in many centers. The aim of this study was to analyze long-term outcomes following AVSD repair over a 21-year period. METHODS: A total of 202 consecutive patients underwent surgical AVSD correction between June 1999 and December 2020. Surgery was performed using the double-patch technique. The study data were prospectively collected and retrospectively analyzed. Primary outcomes were In-hospital mortality and overall long-term freedom from reoperation. RESULTS: Median age at operation was 120 days (IQR 94-150), median weight was 5.0 kg (4.2-5.3). None of the patients died within the first 30 postoperative days. In-hospital mortality was 0.5% (1/202 patients). Median follow-up was 57 months (11-121). Overall freedom from reoperation at 5, 10 and 15 years was 91.8%, 86.9% and 86.9%, respectively. CONCLUSION: AVSD repair with the double-patch technique is a safe and effective procedure with good early postoperative outcomes and low long-term reoperation rates.

Cardiac Surgery in Patients with Parkinson's Disease: A Retrospective Analysis of a High-Risk Cohort.

BACKGROUND: Little is known about the perioperative course of patients with Parkinson's disease (PD) undergoing cardiac surgery. The objective of this study was to identify the influence of PD on the perioperative course and to improve treatment. METHODS: Perioperative data were analyzed retrospectively from 130 patients undergoing cardiac surgery between September 2001 and April 2013 who had PD and were compared using 1:1 matched-pair analysis with 130 controls not affected by PD. RESULTS: The 30-day all-cause mortality (4.6 vs. 9.2%; p = 0.21; odds ratio [OR] = 0.45; 95% confidence interval [CI]: 0.16, 1.31) and the overall all-cause mortality (27.7 vs. 28.5%; hazard ratio [HR] = 0.96 [0.56, 1.66]; p = 1.00) were not significantly different between PD patients and the control group. Emergency surgery (p = 0.04; OR = 3.20; 95% CI: 1.06, 9.66) and postoperative pneumonia (p < 0.001; OR = 11.3; 95% CI: 3.06, 41.6) were associated with 30-day mortality. Independent predictors of all-cause mortality were age at surgery (p = 0.01; OR = 3.58; 95% CI: 1.38, 9.30), NYHA (New York Heart Association) classification stage IV (p = 0.02; OR = 17.3; 95% CI: 1.52, 198), and postoperative pneumonia (p = 0.05; OR = 46.4; 95% CI: 0.97, 2219). We did not observe an association of PD with short- or long-term all-cause mortality after adjustment for associated covariates. CONCLUSIONS: We found that PD is not a significant risk factor for perioperative morbidity and mortality in our cohort. Our study showed that patients with PD had outcomes that were similar to those of non-PD patients.
