Combined valve and coronary artery surgery

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery Outcomes
• Valvular Heart Disease Treatment

Background:

• Patients with concurrent valvular heart disease and coronary artery disease often require complex surgical interventions.
• The optimal surgical strategy, whether combined valve replacement and coronary artery bypass grafting (CABG) or isolated valve replacement, remains a subject of investigation.
• Previous studies have yielded varied results regarding the comparative efficacy and safety of these approaches.

Purpose of the Study:

• To compare the early and late outcomes of combined valve replacement and CABG surgery with those of isolated valve replacement.
• To evaluate the impact of combined procedures on patient morbidity, mortality, and functional status.
• To determine if combined valve and coronary surgery offers comparable results to valve replacement alone.

Main Methods:

• A retrospective study comparing two groups of patients: Group 1 (79 patients) underwent combined valve replacement and CABG (1970-1978), and Group 2 (79 patients) underwent isolated valve replacement.
• Patient demographics, preoperative conditions (including New York Heart Association Functional Class and angina presence), angiographic findings, and surgical details were analyzed.
• Early morbidity and mortality, as well as late mortality and functional outcomes at an average follow-up of 3.5 years, were compared between the two groups.

Main Results:

• Group 1 patients were more frequently male, older, and presented with more severe angina and abnormal contraction areas on angiography compared to Group 2.
• Early morbidity was higher in Group 1, but early mortality rates were similar (5-6%) in both groups.
• Late mortality (16-17%) and functional outcomes at follow-up were comparable between the combined surgery group and the isolated valve replacement group.

Conclusions:

• Combined valve replacement and CABG surgery carries a similar operational risk and achieves comparable late results to isolated valve replacement.
• The findings suggest that combined procedures are a viable option for patients with concomitant valvular and coronary artery disease, without compromising long-term outcomes.
• This study provides evidence supporting the safety and efficacy of performing both procedures simultaneously when indicated.
