Imaging approaches for pulmonary vein isolation in patients after lobectomy or pneumonectomy: a case series.

ABSTRACT:

Background

In patients who underwent pneumonectomy, pulmonary vein isolation for atrial fibrillation by catheter ablation may be complicated by the anatomical alterations caused by the surgical intervention. Pre- and peri-procedural imaging can visualize and guide the procedure to assure safety and procedural success.

Case summary

This case series describes different imaging and ablation strategies in three cases from three different ablation centres with the unusually challenging and complex anatomical conditions in patients following lobectomy or pneumonectomy.

Discussion

Pulmonary vein isolation in patients with previous pulmonary resection was feasible by both radiofrequency and cryocatheter ablation despite the anatomical alterations caused by the surgery. Pre- and peri-procedural imaging by cardiac computed tomography and transoesophageal echocardiography contributed to an increased understanding of the complex anatomical substrate.

Project description:BackgroundSome patients with non-small cell lung cancer (NSCLC) have superior short- and long-term outcomes with sleeve lobectomy rather than pneumonectomy. Originally sleeve lobectomy was reserved for patients with limited pulmonary function, however, the reported superior results allowed sleeve lobectomy to be performed in expanded patient populations. In a further attempt to improve post-operative outcomes surgeons have adopted minimally invasive techniques Minimally invasive approaches have potential benefits to patients such as decreased morbidity and mortality while maintaining the same caliber of oncologic outcomes.MethodsWe identified patients at our institution who underwent sleeve lobectomy or pneumonectomy to treat NSCLC from 2007 to 2017. We analyzed these groups in respect to 30- and 90-day mortality, complications, local recurrence, and median survival. We included multivariate analysis to determine the impact of a minimally invasive approach, sex, extent of resection, and histology. Differences in mortality were analyzed using the Kaplan-Meier method using the log-rank test to compare the groups. A two-tailed Z test for difference in proportions was done to analyze complications, local recurrence, 30-day and 90-day mortality.ResultsA total of 108 patients underwent sleeve lobectomy (n=34) or pneumonectomy (n=74) for treatment of NSCLC with 18 undergoing open pneumonectomy, 56 undergoing video-assisted thoracoscopic surgery (VATS) pneumonectomy, 29 undergoing open sleeve lobectomy, and 5 undergoing VATS sleeve lobectomy. There was no significant difference in 30-day mortality (P=0.064) but there was a difference in 90-day (P=0.007). There was no difference in complication rates (P=0.234) or local recurrence rates (P=0.779). The pneumonectomy patients had a median survival of 23.6 months (95% CI: 3.8-43.4 months). The sleeve lobectomy group had a median survival of 60.7 months (95% CI: 43.3-78.2 months) (P=0.008). On multivariate analysis extent of resection (P<0.001) and tumor stage (P=0.036) were associated with survival. There was no significant difference between the VATS approach and the open surgical approach (P=0.053).ConclusionsWhen considering patients undergoing surgery for NSCLC sleeve lobectomy resulted in lower 90-day mortality and better 3-year survival compared to patients undergoing PN. Having a sleeve lobectomy rather than a pneumonectomy and having earlier-stage disease lead to significantly improved survival on multivariate analysis. Having a VATS operation leads to a non-inferior post-operative outcome compared to open surgery.
