OBJECTIVE: We present a case series with the aim of describing an innovative robotic-assisted surgical technique. The present study will help to investigate safety, feasibility and short-term outcomes of Robotic Assisted Repair of Atrial Septal Defect using Single-Venous Cannula Bypass Technique via Left atrium. METHODS: This study is a descriptive observational retrospective case series of five patients undergoing robotic surgical management of ASD from February 2021 to March 2022. We collected data from our institution electronic medical records to characterize the cases. Relevant information regarding the patient (sociodemographic and clinical data), procedures (setting of system, ports, cardiopulmonary bypass, clamping, operation time, ventilation time), and ASD (size, hemodynamic measures, associated abnormalities) were included in our study. Cases were excluded when patients without complete data, complex anatomic problems with other primary diagnoses, and patients with non-robotic approaches. RESULTS: Demographic data, intraoperative data and outcomes data assessed and analyzed. Five patients (five females and one male) underwent ASD procedure. The mean age and BMI were 48.2 ± 20.44 and 26.27 ± 8.03. The mean operative time was 276.8 min ± 69.94. Mean duration of intubation time after surgery 211.8 minutes in which two patients were extubated in the OR. The mean length of stay was 7 days (5-10). There were no intraoperative or postoperative complications.
CONCLUSIONS: Robotic-Assisted Repair of Atrial Septal Defect using Single-Venous Cannula Bypass Technique via Left Atrium, was feasible and safe in this initial series. It seems to be adequate for clinical use and can be successfully perform without the risk associated with the insertion of a second cannula.
