Respiratory System Function in Patients After Minimally Invasive Aortic Valve Replacement Surgery: A Case Control Study

Objective: The aim of the study was to comparatively analyze respiratory system function after minimally invasive, through right minithoracotomy aortic valve replacement (RT-AVR) to conventional AVR. Methods: Analysis of 201 patients scheduled for RT-AVR and 316 for AVR between January 2010 and November 2013. Complications of the respiratory system and pulmonary functional status are presented. Results: Complications of the respiratory system occurred in 16.8% of AVR and 11.0% of RT-AVR patients (P = 0.067). The rate of pleural effusions, thoracenteses, pneumonias, or phrenic nerve dysfunctions was not significantly different between groups. Perioperative mortality was 1.9% in AVR and 1.0% in RT-AVR (P = 0.417). Mechanical ventilation time after surgery was 9.7 ± 5.9 hours for AVR and 7.2 ± 3.2 hours for RT-AVR patients (P
