Minimally invasive surgical valve repair

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Techniques
• Cardiac Valve Repair

Background:

• Minimal-access valve repair, introduced in the 1990s, is an emerging alternative to traditional valve surgery.
• This technique offers benefits such as reduced surgical trauma, less postoperative pain, decreased blood loss, and improved cosmetic outcomes.

Purpose of the Study:

• To evaluate the safety and feasibility of minimally invasive valve repair.
• To assess the early postoperative outcomes of patients undergoing this procedure.

Main Methods:

• A retrospective analysis of 17 patients who underwent minimally invasive valve repair between July 2008 and February 2009.
• Cardiac access was achieved via a small incision between the ribs (second or third intercostal space).
• Outcomes were assessed in the intensive care unit (first 24 hours) and before hospital discharge (fourth postoperative day).

Main Results:

• The study included patients undergoing aortic surgery (47%), mitral valve surgery (23.5%), congenital heart defect repair (23.5%), and endocarditis treatment (5.9%).
• Cardiopulmonary bypass times were consistently below 120 minutes (median 90 minutes), and cross-clamp times were below 100 minutes (median 70 minutes).
• No reoperations for bleeding, infections, or myocardial infarction occurred. The operative mortality rate was 5.8%, with a median hospital stay of 5 days.

Conclusions:

• Minimal surgical access, avoiding full sternotomy, enhances chest stability and reduces postoperative pain.
• While offering benefits, limited cardiac exposure is a drawback of the minimally invasive approach.
• Minimally invasive valve repair is a safe and feasible option with excellent outcomes, particularly for elderly patients, requiring attention to the learning curve and complication management.
