Results of minimally invasive aortic valve replacement surgery through right thoracotomy at Hanoi Heart Hospital

Objectives: To evaluate results of minimally invasive aortic valve replacement surgery through right thoracotomy with some techinque improvements in Hanoi Heart Hospital. Methods: Surgery was performed via a small right thoracotomy in the second intercostal space. The third rib was detached by a wedge-shaped way using sternum saw. Cannulation approaches were central or peripheral depended on patients’ condition. Preoperative, perioperative, early results and follow-up data was collected and analysed. Results: There was 48 patients in the research. Mean age was 60,94 ± 11,53 (25-82), and 52,1% was male. 29,2% of patients had peripheral vascular disease. 22,9% underwent central arterial cannulation. 3 patients (6,3%) had pericardial adhesion. There was no early mortality, 2 patients had redo surgery due to excess bleeding. 1 patients had intestinal infarction. Mean follow-up time was 13,4 months. 91,3% of patients had NYHA I. 1 patients was dead due to intracerebral hemorrhage. Conclusions: With some improvements in techniques, minimally invasive aortic valve replacement surgery through right thoracotomy gave good early and midterm results in our center.
