Insights
Surgical anterior ventricular restoration (SAVR) offers a promising surgical option for heart failure patients with ischemic cardiomyopathy. This technique safely restores ventricular geometry, improving outcomes for high-risk individuals.
Area of Science:
- Cardiovascular Surgery
- Heart Failure Management
- Ischemic Cardiomyopathy Treatment
Background:
- Heart failure is a growing concern due to increased life expectancy and effective treatments in younger populations.
- Ischemic cardiomyopathy resulting from myocardial infarction is the leading cause of heart failure.
- Current surgical options like transplantation and ventricular assist devices cannot accommodate all eligible patients.
Purpose of the Study:
- To evaluate ventricular restoration as a surgical approach for myocardial failure caused by post-infarction ventricular dilatation.
- To describe surgical techniques for ventricular restoration in high-risk coronary artery bypass graft (CABG) patients with heart failure.
Main Methods:
- Detailed description of conventional CABG with mitral valve (MV) repair using cardioplegia.
- Description of surgical anterior ventricular restoration (SAVR) on a beating heart for dyskinetic/akinetic areas in ischemic cardiomyopathies.
- Combined approach utilizing both techniques in 195 consecutive patients.
Main Results:
- The combined surgical approach enabled safe restoration of ventricular geometry.
- Minimal use of mechanical circulatory support, such as intra-aortic balloon pump (IABP), was required.
- The procedure was performed by an international team (RESTORE group) on 195 consecutive patients.
Conclusions:
- Ventricular restoration, particularly SAVR, presents a viable surgical option for selected heart failure patients.
- This combined surgical strategy effectively addresses myocardial failure in ischemic cardiomyopathy.
- The technique allows for safe ventricular geometry restoration with limited need for mechanical support.
Abstract:
Heart failure is an increasing problem because of successful therapies in younger age groups and an overall increase in age in the general population. Ischemic cardiomyopathy secondary to myocardial infarction is the most prevalent entity among the several causes for cardiac failure. Among the surgical options for these patients, neither transplantation nor current ventricular assist devices are able to treat a sufficient number of patients. Ventricular restoration, however, may evolve as a surgical option to treat myocardial failure secondary to postinfarction ventricular dilatation. This procedure must be undertaken in high-risk coronary artery bypass graft (CABG) patients in heart failure. We describe the techniques for both the conventional procedure (CABG +/- mitral valve [MV] repair) using cardioplegic methods, and the beating open heart for surgical anterior ventricular restoration (SAVR) for dyskinetic and akinetic areas in ischemic cardiomyopathies. This combined approach allows safe restoration of the ventricular geometry with minimal use of mechanical support (ie, intra-aortic balloon pump [IABP]) in 195 consecutive patients undergoing this procedure by members of an international team called the RESTORE group.
