Redo Coronary Artery Bypass Surgery (Redo CABG) and Valve Replacement Surgery are complex cardiac procedures performed when previous heart surgeries have failed or when heart valve disease progresses over time.
Redo Bypass Surgery (Redo CABG) is performed on patients who previously underwent Coronary Artery Bypass Grafting (CABG) but have developed new blockages due to progressive coronary artery disease or graft failure. Since the chest may have scar tissue from the initial surgery, redo CABG requires advanced surgical techniques, including the use of arterial grafts like the internal mammary or radial artery. In some cases, minimally invasive or hybrid procedures (a combination of surgery and stenting) may be considered to reduce surgical risks.
Valve Replacement Surgery is necessary when heart valves become severely diseased or dysfunctional due to conditions like aortic stenosis, mitral regurgitation, or prosthetic valve failure.
It can be performed as an open-heart procedure or through minimally invasive techniques such as Transcatheter Aortic Valve Replacement (TAVR) for high-risk patients. Valves can be replaced with either mechanical valves, which require lifelong anticoagulation therapy, or biological valves, which have a limited lifespan but do not require blood thinners.
Both redo CABG and valve replacement surgeries require expertise in complex cardiac procedures. Advances in surgical techniques and minimally invasive approaches have improved outcomes, reducing complications and enhancing long-term heart function for patients undergoing these challenging procedures.
