Valve-Sparing Aortic Root Replacement Technique: Valsalva Graft versus Two Straight Tubular Grafts

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Surgery

Background:

• Valve-sparing aortic root replacement (VSARR) encompasses diverse surgical techniques.
• Graft choice significantly influences VSARR outcomes.

Purpose of the Study:

• To compare mid-term outcomes of VSARR using Valsalva graft versus two straight tubular grafts.
• To evaluate the impact of graft type on patient survival and reoperation rates.

Main Methods:

• Retrospective analysis of 332 patients undergoing VSARR between 2004 and 2020.
• Comparison between Valsalva graft (n=270) and two straight tubular grafts (n=62).
• Primary endpoints: mid-term survival and freedom from reoperation.

Main Results:

• Both techniques demonstrated excellent outcomes with similar operative mortality.
• The two-graft group showed a trend towards improved 5-year survival (100% vs. 96%) and freedom from reoperation (100% vs. 93%).
• Slightly higher postoperative complications were noted in the Valsalva group, though not statistically significant.

Conclusions:

• Both Valsalva and two-graft VSARR techniques yield excellent short- and mid-term results.
• The two-graft technique may offer a slight advantage in survival and reoperation rates.
• Larger studies with longer follow-up are needed to confirm the significance of these potential benefits.
