Insights
Minimally invasive coronary artery bypass grafting on a beating heart offers a safe and effective option for high-risk patients, especially when combined with other surgical procedures. This approach avoids cardiopulmonary bypass, leading to excellent outcomes with no mortality or morbidity observed in this study.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Procedures
- High-Risk Patient Management
Background:
- Coronary artery disease surgical management has advanced, but high-risk patients face increased perioperative risks with cardiopulmonary bypass.
- Elderly patients, those with reduced ejection fraction, severe aortic calcification, comorbidities, or requiring reoperation are particularly vulnerable.
- Minimally invasive coronary artery bypass grafting without cardiopulmonary bypass has shown promise in select cases.
Purpose of the Study:
- To evaluate the safety and efficacy of minimally invasive coronary artery bypass grafting in high-risk patients undergoing combined procedures.
- To assess the feasibility of off-pump coronary artery bypass grafting in conjunction with vascular, abdominal, or device implantation surgeries.
Main Methods:
- Minimally invasive coronary artery bypass grafting on a beating heart was performed in 8 high-risk patients.
- These procedures were combined with vascular surgeries (carotid endarterectomy, aortic replacement), abdominal procedures (pancreas-kidney transplant follow-up), or defibrillator implantations.
- The study focused on patients who would typically have increased perioperative risk with traditional cardiopulmonary bypass.
Main Results:
- No mortality or morbidity was observed postoperatively in the studied group.
- No blood transfusions were required for any of the patients.
- Patients remained symptom-free at an average follow-up of 5.5 months.
Conclusions:
- Minimally invasive coronary artery bypass grafting is a valuable technique for high-risk patients with significant coronary artery disease.
- The technique is particularly beneficial when noncardiac procedures must be performed concurrently.
- This approach can reduce perioperative risks associated with cardiopulmonary bypass in complex surgical scenarios.
Background:
Surgical management of coronary artery disease has improved dramatically over the last decades in terms of short- and long-term results. Nevertheless, elderly patients (more than 75 years); patients with reduced ejection fraction (less than 0.25), heavily calcified aorta, or coexisting noncardiac diseases; and patients requiring cardiac reoperation have an increased perioperative risk when operated on with cardiopulmonary bypass. Successful minimally invasive coronary artery bypass grafting without cardiopulmonary bypass has been reported in selected cases.
Methods:
In 8 of 40 high-risk patients undergoing operation on a beating heart, minimally invasive coronary bypass grafting was combined with vascular (carotid endarterectomy, n = 3; aortic replacement, n = 2) and abdominal procedures (a second look after combined pancreas and kidney transplantation) or defibrillator implantations (n = 2).
Results:
Postoperatively, there was no mortality, no morbidity, and no blood transfusion. Patients are free of symptoms at an average follow-up time of 5.5 +/- 5 months.
Conclusions:
Our results indicate that minimally invasive coronary artery bypass grafting technique can be particularly useful if noncardiac procedures have to be performed in high-risk patients with significant coronary artery disease.
