Left Ventricular Support Systems for High-Risk PCI: How Can We Improve Outcomes for Rare Procedures?
High-risk percutaneous coronary interventions (PCI) are becoming more prevalent as the ability to perform complex coronary interventions continues to improve. Patients for whom high-risk interventions are considered generally have severe diffuse coronary artery disease, a single last patent conduit, or significant left main disease with large territories of myocardial ischemia. In addition, these patients also typically have reduced left ventricular function (ejection fraction less than 25% to 35%) with comorbidities that make them high risk for standard coronary artery bypass grafting. Thus, PCI is increasingly used as a viable alternative for coronary revascularization, but it too is associated with a high degree of morbidity and mortality.
