POSTOPERATIVE CHEST PAIN AND COSMETIC OUTCOMES IN MINI-STERNOTOMY VERSUS STANDARD STERNOTOMY IN AORTIC VALVE REPLACEMENT

Abstract

Background: For decades, the traditional median sternotomy has been the treatment of choice in aortic valve
surgery; however, numerous researchers have worked to develop less invasive procedures, and the partial upper
mini-sternotomy is the most prevalent minimally invasive procedure.
Objective: To compare outcomes, in patients who undergo mini-sternotomy, and patients who undergo standard
sternotomy, in aortic valve replacement operations.
Patients and Methods: This Randomized controlled clinical trial study included A fifty patients who were
admitted to the Zagazig University hospital, Cardiothoracic surgery department In the period between January
2021 to August 2021, Patients were split into two groups, each with 25 patients: Group "A" had aortic valve
surgery by mini-sternotomy, while Group "B" got aortic valve surgery via open surgery. Aortic valve surgery
was performed via a conventional median sternotomy in Group "B." An ECG was performed to see whether
there was any ischemia present, as well as laboratory tests and a chest x-ray.
Results: At all periods, VAS was substantially higher in the complete sternotomy group. Wound length was
significantly shorter in mini-sternotomy group than in full sternotomy group, however: regarding post operative
NYHA there were significant improvement in both groups but better improvement in Mini group.
Conclusions: MIAVR is a safe and effective procedure and is performed with comparable morbidity to
conventional AVR. MIAVR results in substantially improved postoperative respiratory functioning, post
operative chest pain, and cosmetic results
