In STEMI patients undergoing PPCI, both bSS and rSS can predict mortality at 12 months. Every point on the rSS confers an additional 6% mortality risk. Calculation of the rSS after culprit lesion intervention may help guide management of non-culprit lesions.

Background: National registries have provided data on in-hospital outcomes for several cardiac procedures. The available data on in-hospital outcomes and its predictors after pericardiocentesis are mostly derived from single center studies.Furthermore, the outcomes after pericardiocentesis for iatrogenic pericardial effusion and the impact of procedural volume on in-hospital outcomes in the United States are largely unknown.Methods: We used national inpatient database files for the years 2009-2013 to estimate the inpatient outcomes after pericardiocentesis in all-comers and in the subgroups with iatrogenic effusion. We also studied the impact of hospital procedural volume, among other predictors, on inpatient mortality.Results: About 64,070 (95%CI 61 008-67 051) pericardiocentesis were performed in the United States during 2009-2013. Of these, 57.15% (56.02-58.26%) of the pericardiocentesis were in hemodynamically unstable patients. Percutaneous cardiac procedures were performed in 17.7% of patients (percutaneous coronary intervention (PCI) 4.02%, electrophysiologic procedures 13.58%, and structural heart intervention (SHI) 0.76%). Overall inpatient mortality was 12.30% (95%CI 11.66-12.96%). Inpatient mortality after PCI, electrophysiologic procedures, SHI and cardiac surgery were 27.67% (95%CI 24-31.67%), 7.8% (95%CI 6.67-9.31%), 22.36% (95%CI 15.06-31.85%) and 18.97% (95%CI 15.84-22.57%), respectively. There was an inverse association between hospital procedural volume and inpatient mortality, with a mortality of 14.01% (12.84-15.26%) at the lowest and 10.82% (9.44-12.37%) at highest quartile hospitals by procedure volume (p trend = 0.001). Conclusion:The inpatient mortality after pericardiocentesis is high, particularly when associated with PCI and SHI.

A timely pericardiocentesis can be lifesaving in tamponade; else, a pericardiocentesis is done for large effusions for diagnostic and therapeutic reasons. The current European Society of Cardiology guidelines gives pericardiocentesis a J Interv Cardiol. 2018;31:815-825.wileyonlinelibrary.com/journal/joic

Tricuspid dP/dt correlates well with CMR RVEF. A dP/dt of more than 400 mmHg/sec strongly predicts normal RVEF. Adjusting for preload (dP/dt/Vmax) further improves this correlation.

The presence of LISA at a follow up of 6-18 months after stent implantation is associated with a higher risk of late/very late ST and MI. Additional studies are required to establish a cause and effect, and inform the management strategy. © 2017 Wiley Periodicals, Inc.
