Assessment of the relationship between distance and ischemic time showed an 18-minute increase for every additional 100 miles of travel. Multivariable logistic regression indicated increased mortality with longer ischemic times, but no difference in survival with increasing distances. Further, on multivariable time-dependent analysis, increasing ischemic time was a predictor of mortality (odds ratio, 1.19 [1.01-1.21]), whereas increased donor distance was not (odds ratio, 0.84 [0.68-1.04]).</div></div><div><h3>Conclusions</h3><div>Distance between donor and transplant center minimally affected ischemic time and showed no impact on post-transplant 1-year survival. Therefore, ischemic time limitations rather than distance cutoffs may be more appropriate for policies regarding heart procurement.</div></div>","PeriodicalId":74032,"journal":{"name":"JTCVS open","volume":"25 ","pages":"Pages 241-252"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144320954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In total, 12 patients who underwent univentricular repair (group U) and 18 patients who underwent biventricular repair (group B) were included in the analysis. Left heart obstructive diseases included critical aortic stenosis, coarctation complex, interruption of aortic arch, and hypoplastic left heart complex. The Z-scores of the mitral, aortic, tricuspid, and pulmonary valve diameters, along with other parameters, were compared before and after bilateral pulmonary artery banding. Three months after the initial bilateral pulmonary artery banding, a cardiac catheter examination was performed in all patients to determine whether univentricular repair or biventricular repair should be performed.</div></div><div><h3>Results</h3><div>Mitral valve size in group B was significantly larger than in group U both before (−0.27 ± 1.04 vs −2.25 ± 1.83, <em>P &lt;</em> .01) and after bilateral pulmonary artery banding (0.05 ± 1.58 vs −1.86 ± 1.91, <em>P &lt;</em> .01). In group U, mitral and aortic valve sizes showed no significant increase after bilateral pulmonary artery banding. In group B, mitral valve size showed no significant increase after bilateral pulmonary artery banding (−0.27 ± 1.04 vs 0.06 ± 1.58, <em>P =</em> .26), whereas aortic valve size demonstrated a significant increase (−4.33 ± 2.60 vs −3.13 ± 2.64, <em>P =</em> .02).</div></div><div><h3>Conclusions</h3><div>In cases of a “borderline” left ventricle, a large mitral valve from birth and growth of the aortic valve are crucial for successful biventricular repair.
