Brief Summary

Lung resection is associated with high postoperative morbidity and mortality and leads to a significant long-term decrease in functional capacity, particularly due to cardiorespiratory complications. One of the contributing factors to this functional decline is the postoperative reduction in right ventricular function. Due to the anatomical proximity and interactions, right ventricular function is evaluated by echocardiography following lung resection. The pulmonary artery pressure (PAP)/tricuspid annular plane systolic excursion (TAPSE) ratio is a parameter that provides a more comprehensive assessment of right heart function by evaluating both right ventricular systolic function and pulmonary artery pressure. In this study, investigators aimed to evaluate changes in right heart function by performing preoperative and postoperative echocardiographic assessments in participants undergoing lung resection, focusing on PAP/TAPSE ratios.

Conditions

Pulmonary Resection; Right Ventricular Function; Echocardiography; Cardiothoracic Anesthesia

Keywords

pulmonary resection; right ventricular function; echocardiography; cardiothoracic anesthesia

Outcome Measures

Primary Outcomes (2)

• Echocardiographic Assessment: TAPSE/PASP Ratio

  Patients will undergo transthoracic echocardiographic evaluation preoperatively, on postoperative days 2-4, and at postoperative month 2. The TAPSE/PASP ratio will be calculated and recorded in mm/mmHg as a non-invasive surrogate of right ventricular-pulmonary arterial coupling.

  Preoperatively, on postoperative days 2-4, and at postoperative month 2

• Echocardiographic Assessment: Tricuspid Annular Plane Systolic Excursion (TAPSE)

  Patients will undergo transthoracic echocardiographic evaluation preoperatively, on postoperative days 2-4, and at postoperative month 2. TAPSE will be measured and recorded in millimeters (mm).

  Preoperatively, on postoperative days 2-4, and at postoperative month 2

Other Outcomes (1)

• Echocardiographic Assessment: Pulmonary Artery Systolic Pressure (PASP)

  Preoperatively, on postoperative days 2-4, and at postoperative month 2
