OBJECTIVE: Benign tumours of the atrial are a rare find during surgical procedure. Contemporary cardiac surgery is searching for alternatives to a full median sternotomy. Minimally invasive techniques are more and more popular. Using right lateral minithoracotomy allows to remove atrial tumors. The aim of this study is a presentation of the results of atrial tumors removal through minimally invasive approach.
METHODS: 117 minimally invasive procedure were analyzed. Selected group of 10 patients underwent removal of the atrial tumors. The average age of the patient was 63,1. The ejection fraction was between 25-65%. The surgical access was right lateral minithoracotomy with use of extracorporeal circulation via femoral vessels . In one case cannulation was provide via alternative access- cervical vessels. When tumor involved tricuspid valve additionally right internal jugular vein was cannulated.
RESULTS: 7 cardiac tumors were removed from the left atrium and 1 from right atrium. In 2 other cases thrombus and abscess were diagnosed intraoperatively and removed. 9 patients were extubated in the day of the operation. 1 patient needed mechanical ventilation for next 3 days. Only 3 patients needed short temporary pharmacological support of the cardiovascular system. In all patients tumors were safety and fully removed. We didn’t observe any stroke.
Observed complication: postoperative bleeding (1 patient.
CONCLUSIONS: Minimally invasive approach via right lateral minithoracotomy is a safe and effective method for the removal of atrial tumors. We observed small amount of complications such as bleeding or respiratory distress. Carotid artery and internal jugular vein were a good alternative access for cannulation for minimally invasive approach.
