Traction suture modification of the Cosgrove hemisternotomy technique

Area of Science:

• Cardiac Surgery
• Minimally Invasive Procedures
• Aortic Valve Surgery

Background:

• Minimally invasive cardiac surgery is increasingly important.
• The Cosgrove technique is a standard hemisternotomy approach.
• Optimizing exposure, especially of the right atrium, remains a challenge.

Purpose of the Study:

• To present a personalized modification of the Cosgrove technique.
• To improve exposure of the right atrium during aortic valve surgery.
• To detail a novel traction suture method for enhanced visualization.

Main Methods:

• A 2 cm right anterior intercostal incision was added to the standard hemisternotomy.
• A Roberts clamp was used to create a traction suture on the right pericardial flap.
• This facilitated improved exposure of the right atrium.
• The incision was also utilized for pericardial drain insertion.

Main Results:

• The modified technique was successfully applied to 66 patients between January 2005 and March 2010.
• The patient cohort included 43 men and 23 women, with a mean age of 60.47 years.
• No intraoperative conversions, cases of cardiac tamponade, or postoperative fatalities were recorded.

Conclusions:

• The traction suture technique offers a simple and safe method for optimizing right atrial exposure.
• This modification addresses a common difficulty in minimally invasive aortic valve surgery.
• The approach demonstrates excellent safety and efficacy in a clinical setting.
