Right Ventricular Dysfunction Incidence After Major Lung Resection

Right Ventricular Dysfunction Incidence After Major Lung Resection, a Prospective Study.

This study aims to describe incidence of right ventricular dysfunction after major lung resection with echocardiography criteria.

Few clinical trial studied the incidence of right ventricular dysfunction after major lung resection and time frame of occurrence.

In this prospective observational study the right ventricular function will be mesure with echocardiographic criteria. Echocardiographic exam will be standardised and be realised day before surgery (at the same time that inclusion), day 1, day 2 and day 3 after surgery.

In order to assess prognostic value of right dysfunction after lung resection, data as hospitalization stay, complications and survival will be collected at 6 months.

Cardiac cycles will be recorded and be analysed by a single observer blind to the clinical finding and other echocardiographic measurements.

Inclusion Criteria:

• Written consent
• Patient older than 18 years
• Major lung surgery (pneumonectomy, lobectomy)

Exclusion Criteria:

• Pre-existing pulmonary arteria hypertension
• Post-operative surgical complication on day 1 to 3 (bleeding, revision surgery)
• Technical difficulty preventing adequate echocardiographic assessment
• Patient refusal
