Percutaneous balloon aortic valvuloplasty (PBAV) is a procedure used for palliation, bridging to surgery, and as an integral step in the procedure for percutaneous aortic valve replacement. Older patients with severe aortic stenosis are thought to have greater risk for adverse perioperative events than younger patients. The aim of this study was to evaluate the outcomes of patients aged >80 years and those aged < or =80 years who underwent PBAV to identify factors associated with adverse clinical outcomes. This was a retrospective study of 111 consecutive patients with severe symptomatic aortic stenosis who underwent retrograde PBAV at Massachusetts General Hospital from December 2004 to December 2008. Forty-nine patients (44%) were men, and the mean age for the whole group was 82 +/- 8 years. Patients were divided into 2 age groups: those aged >80 years (n = 73) and those aged < or =80 years (n = 38). Procedural outcomes, complications, and in-hospital adverse events were compared. Multivariate logistic regression was used for the adjusted analysis. Nearly 90% of patients were in New York Heart Association class III or IV. Patients aged >80 years had lower baseline ejection fractions (43.5% vs 56.1%, p <0.01) and smaller aortic valve areas (0.59 vs 0.73 cm(2), p <0.01). Although the 2 age groups had a similar percentage of aortic valve area increase (55.5% vs 45.2%, p = 0.28), those aged >80 years had smaller post-PBAV aortic valve areas (0.89 vs 1.02 cm(2), p <0.05). Overall, in-hospital mortality was 8.1%, with no significant differences between the groups. Advanced age was not an independent predictor of in-hospital death, myocardial infarction, stroke, cardiac arrest, or tamponade; however, patients aged >80 years had a significantly higher incidence of intraprocedural emergent intubation and cardiopulmonary resuscitation compared to the younger group. New York Heart Association class was the only independent predictor of worse in-hospital outcomes. In conclusion, compared to younger patients, those aged >80 years had less favorable preprocedural characteristics for PBAV but similar overall in-hospital clinical outcomes. Patients aged >80 years had significantly higher incidence of emergent intubation and cardiopulmonary resuscitation during PBAV.
