Nonsystem Reasons for Delay in Door-to-Balloon Time and Associated In-Hospital Mortality A Report From the National Cardiovascular Data Registry
ObjectivesThe goal of this study was to characterize nonsystem reasons for delay in door-to-balloon time (D2BT) and the impact on in-hospital mortality.BackgroundStudies have evaluated predictors of delay in D2BT, highlighting system-related issues and patient demographic characteristics. Limited data exist, however, for nonsystem reasons for delay in D2BT.MethodsWe analyzed nonsystem reasons for delay in D2BT among 82,678 ST-segment elevation myocardial infarction patients who underwent primary percutaneous coronary intervention within 24 h of symptom onset in the CathPCI Registry from January 1, 2009, to June 30, 2011.ResultsNonsystem delays occurred in 14.7% of patients (n = 12,146). Patients with nonsystem delays were more likely to be older, female, African American, and have greater comorbidities. The in-hospital mortality for patients treated without delay was 2.5% versus 15.1% for those with delay (p < 0.01). Nonsystem delay reasons included delays in providing consent (4.4%), difficult vascular access (8.4%), difficulty crossing the lesion (18.8%), “other” (31%), and cardiac arrest/intubation (37.4%). Cardiac arrest/intubation delays had the highest in-hospital mortality (29.9%) despite the shortest time delay (median D2BT: 84 min; 25th to 75th percentile: 64 to 108 min); delays in providing consent had a relatively lower in-hospital mortality rate (9.4%) despite the longest time delay (median D2BT: 100 min; 25th to 75th percentile: 80 to 131 min). Mortality for delays due to difficult vascular access, difficulty crossing a lesion, and other was also higher (8.0%, 5.6%, and 5.9%, respectively) compared with nondelayed patients (p < 0.0001). After adjustment for baseline characteristics, in-hospital mortality remained higher for patients with nonsystem delays.ConclusionsNonsystem reasons for delay in D2BT in ST-segment elevation myocardial infarction patients presenting for primary percutaneous coronary intervention are common and associated with high in-hospital mortality

Impact of paravalvular leak on left ventricular remodeling and global longitudinal strain 1 year after transcatheter aortic valve replacement
Background:New mild or persistent moderate paravalvular leak (PVL) is a
known predictor of poor outcomes after transcatheter aortic valve
replacement (TAVR). Its impact on left ventricular (LV) remodeling and
global longitudinal strain (GLS) has not been well studied.Materials &
methods:We collected echocardiographic data in 99 TAVR patients. LV
remodeling and GLS were compared between patients with and without
PVL.Results:Patients without PVL (n = 84) had significant LV ejection
fraction, wall thickness and LV mass improvement compared with patients
with PVL (n = 15; p < 0.001 for all). Diastolic function worsened in
patients with PVL. Baseline GLS improved significantly regardless of PVL
(p = 0.016 and p = 0.01, respectively) and was not predictive of LV
ejection fraction or LV mass improvement when analyzed in
tertiles.Conclusion:PVL impedes reverse LV remodeling but not GLS
improvement 1-year after TAVR. Baseline GLS was not a predictor of LV
remodeling
