ABSTRACT
BACKGROUND:
This study aimed to investigate the relationship between postoperative atrial fibrillation (POAF) after esophagectomy and pre-existing cardiac substrate.METHODS:
We retrospectively analyzed 212 consecutive patients from between July 2010 and December 2022 who were scheduled to undergo esophagectomy for esophageal cancer without previous history of atrial fibrillation. All the patients underwent both echocardiography and contrast-enhanced multi-detector computed tomography (MDCT).RESULTS:
POAF occurred in 49 patients (23.1%). Multivariable logistic analysis demonstrated that independent predictors for POAF were age [OR; 1.06 (1.01-1.10), P < 0.01), three-field lymph node dissection [OR; 2.55 (1.25-5.23), P < 0.01), left atrial dilatation (> 35 mm) assessment by echocardiography [OR; 3.05 (1.49-6.25), P < 0.01) and common left pulmonary vein [OR; 3.03 (1.44-6.39), P < 0.01). The correlation coefficient was high for left atrial dimensions assessed by echocardiography and MDCT (r = 0.91, P < 0.01). Combination of left atrial dilatation by echocardiography and common left pulmonary vein had high odds ratio [OR; 8.10 (2.62-25.96), P < 0.01). Instead of echocardiographic assessment, combination of left atrial enlargement (> 35 mm) assessed by MDCT and common left pulmonary vein also showed high odds ratio for POAF [OR; 11.23 [2.19-57.63], P < 0.01).CONCLUSION:
Incidence of POAF after esophagectomy was related to both left atrial enlargement and common left pulmonary vein assessed by preoperative MDCT. Additional analysis of atrial size and pulmonary vein variation would facilitate preoperative assessment of the risk of POAF, but future studies must ascertain therapeutic strategy.Palavras-chave
