Prognosis of Right Ventricular Dysfunction Assessed by Speckle Tracking in Postoperative Thoracic Surgery: a Pilot Study

In postoperative thoracic surgery (lobe resection, pneumonectomy or wedge resection), cardiovascular complications are the most frequent (10 to 15%) with a significant morbi-mortality rate. Right ventricular (RV) dysfunction is a complication that can be multifactorial in post thoracic surgery. The RV longitudinal shortening fraction (RV-LSF) is a new 2D-STE parameters able to more accurately detect patients with RV dysfunction compared to conventional echocardiographic parameters. This project is a single-center, prospective, interventional study of patients hospitalized at the Amiens University Hospital for scheduled thoracic surgery. TTE is performed preoperatively, at day 2 and day 15 following the thoracic surgery. Echocardiographic parameters will be measured by an echocardiographic expert in offline with a dedicated software. MACE criteria will be collected at day 2, day 15 and day-30 following the thoracic surgery.

the included patients have a TTE preoperatively in order to evaluate the RV systolic function. TTE will also be done at day 2 and day-15 during the follow-up surgical consultation.

MACE is a composite criteria. MACES criteria is defined as the occurrence of at least one of the following events: A cardiovascular death or a documented supraventricular tachycardia (atrial fibrillation and/or flutter) of duration > 30 seconds or, an acute myocardial infarction or, an hospitalization for a right ventricular failure or, an hospitalization for a left ventricular failure.

Inclusion Criteria: Adult patient (>18 years) Patient hospitalized at the Amiens University Hospital for scheduled thoracic surgery (lobectomy, pneumonectomy, wedge resection). Surgery by thoracotomy or video-assisted thoracic surgery Information of the patient and collection of his non-opposition Exclusion Criteria: Patient with poor echogenicity on TTE not allowing evaluation of 2D-STE or conventional parameters of the RV. Patient with a rapid supraventricular rhythm disorder (HR > 100) at the time of TTE Patient under mechanical ventilation Patient under extracorporeal membrane oxygenation Patients under guardianship or legal protection Patients whose clinical condition does not allow for their non-opposition Pregnant women
