Minimally invasive, Aortic valve replacement (AVR), Early result


Background: Aortic valve disease is a common valvular heart disease and its incidence is likely to increase with age. The conventional approach in the treatment of aortic valve disease is aortic valve replacement (AVR) through a full sternotomy. Minimally invasive aortic valve replacement (MIAVR) is defined as an AVR procedure that involves a small chest wall incision. The MIAVR is a safe procedure, less invasive approach, while maintaining the same efficacy and quality of a conventional approach.

Objectives: The main objectives of this study were clinical outcomes, postoperative complication and functional class are reviewed.

Method: A retrospective study of our database identified 23 patients who underwent MIAVR at Central Chest Institute of Thailand from January 2017 to January 2019.

Results: There were 15 men, with a mean age of 58 years. The patients presented with congestive heart failure (44%) and angina (39%). Most of the patients (69.6%) were in New York Heart Association (NYHA) class III. Left ventricular ejection fraction 62.5%± 9%. Mean cross clamp time was 83.3±13.6 minutes and mean cardiopulmonary bypass (CPB) time was 102.3± 14.8 minutes. There is no in-hospital mortality and neurological complication. One patient underwent reoperation due to aortic paravalvular leakage. The length of stay (LOS) in ICU was 1.2±0.2 days and LOS in hospital was 7 day. All of the patients were New York Heart Association class I after the operation.

Conclusion: Minimally invasive AVR can be performed safely and effectively with very few perioperative complications. The early outcome in these patients are excellent.
