Propensity score‐based analysis of 30‐day survival in cardiogenic shock patients supported with different microaxial left ventricular assist devices

Journal of cardiac surgery, 2021
Microaxial left ventricular assist devices are used increasingly for treating cardiogenic shock. We compared the short‐term outcome of patients supported with different microaxial devices for cardiogenic shock.

Cost-effectiveness of left ventricular assist devices (LVADs) for patients with advanced heart failure : analysis of the British NHS Bridge to Transplant (BTT) program [PDF]

, 2001
Background: A previous cost-effectiveness analysis showed that bridge to transplant (BTT) with early design left ventricular assist devices (LVADs) for advanced heart failure was more expensive than medical management while appearing less beneficial ...

Pressure-Volume Loop Analysis in Percutaneous Coronary Intervention-Induced Shock

JACC: Case Reports, 2020
High-risk percutaneous coronary intervention may lead to undesirable clinical scenarios such as cardiogenic shock. We describe the hemodynamic changes using pressure-volume loop analyses in percutaneous coronary intervention-induced shock.

Recurrent Takotsubo Cardiomyopathy in a Patient With Hypertrophic Cardiomyopathy Leading to Cardiogenic Shock Requiring VA-ECMO

JACC: Case Reports, 2020
Providing hemodynamic support for patients with hypertrophic cardiomyopathy and cardiogenic shock can be challenging because inotropic medications worsen intraventricular obstruction, and the effect of appropriate mechanical support remains undefined. We
