Nonoperative interventional procedures are increasingly viable options for patients considered too ill for surgery. The long-term benefits of catheter-based interventions such as aortic valve replacements or stents for aortic aneurysms and dissections are favorable and continue to be elucidated. In particular, the substantially reduced morbidity attributable to catheter-based interventions makes these procedures compelling options for high-risk patients who may not survive open operations.
