According to our findings, ESL is a safe and feasible procedure that does not compromise oncological principles. It can be considered an appropriate alternative to pneumonectomy and should be considered in patients with centrally located tumours.

Venoarterial extracorporeal membrane oxygenation (VA ECMO) is widely used in patients with cardiogenic shock. Insufficient decompression of the left ventricle (LV) is considered a major factor preventing adequate LV recovery. A 40-year-old male was diagnosed with acute myocardial infarction, and revascularization was performed using percutaneous stenting. However, cardiogenic shock occurred, and VA ECMO was initiated. Severe LV failure developed, and percutaneous transaortic catheter venting (TACV) was incorporated into the venous circuit of VA ECMO under transthoracic echocardiography guidance. The patient was successfully weaned from VA ECMO. Percutaneous TACV is an effective, relatively noninvasive, and rapid method of LV decompression in patients undergoing VA ECMO.

Extracorporeal membrane oxygenation (ECMO) has become one of the often applied mechanical support for acute cardiogenic shock. During venoarterial (VA) ECMO support, left heart decompression should be considered when left ventricular (LV) distension develops with pulmonary edema and LV dysfunction. The aim of this study was to report the results of transaortic catheter venting (TACV), as an alternative venting method, performed during VA-ECMO in patients with acute cardiogenic shock. We retrospectively reviewed the records of seven patients who underwent both ECMO and TACV between February 2013 and February 2014. Extracorporeal membrane oxygenation was performed uneventfully, and TACV was introduced under transthoracic echocardiographic guidance in all cases. Hemodynamic parameters, LV ejection fraction, and LV end-diastolic dimension (LVEDD) were measured 24 hours after initiating TACV in survivors. There were no procedure-related complications. Four of the seven patients (58%) survived. Transaortic catheter venting led to an increase in mean blood pressure in all patients (p = 0.050). There was a significant difference between pre- and post-TACV-LVEDD (59 ± 14 vs. 50 ± 12 mm, p = 0.044), with a 10-23% reduction in LVEDD in survivors. Transaortic catheter venting might be an acceptable alternative to venting procedures and useful for LV recovery during VA-ECMO in patients with severe LV dysfunction.
