TL;DR: This study suggests that chronic intravenous milrinone provides an adequate strategy as a bridge to transplant if the waiting time is short, whereas an elective ventricular assist device implantation may be a safer strategy for patients expected to wait longer.

TL;DR: UR(max) best reflects LV relaxation in comparison with the 2 other algorithms, and was significantly lower in patients with tau>/=48 ms than in patientswith tau<48 ms (P=.004), most of whom had a depressed LV ejection fraction.

TL;DR: The case of this patient shows that high-risk patients who have experienced cardiogenic shock with multiorgan failure and coagulopathy can benefit from the TandemHeart pVAD as a bridge to other therapeutic options, even when creative approaches to treatment and to Tandem heart insertion are required.
Abstract: The TandemHeart percutaneous ventricular assist device (pVAD), which provides temporary circulatory support of the left ventricle, can be used in high-risk and hemodynamically unstable patients The easily inserted TandemHeart provides cardiac support superior to that from the use of intra-aortic balloon pumps Herein, we discuss TandemHeart implantation via end-to-side femoral arterial grafting in a cardiac patient whose sepsis and multiorgan failure were complicated by coagulopathy and thromboembolism A 47-year-old woman, on intra-aortic balloon and intravenous inotropic support after an acute myocardial infarction and emergency coronary artery bypass grafting, was transferred to our institution via helicopter She developed sepsis and multiorgan failure Her condition was further complicated by coagulopathy and a left-lower-extremity thromboembolism After 6 weeks of aggressive pharmacologic and intermittent intra-aortic balloon treatment, the patient developed cardiogenic shock and received a TandemHeart pVAD for short-term circulatory support A GORE-TEX access graft, sewn end-to-side to the femoral artery because of the patient's leg ischemia and very small vessels, served as a conduit for the TandemHeart's femoral arterial inflow cannula Her difficult circulatory, anatomic, and coagulopathic status stabilized after 2 weeks of TandemHeart support, and she was bridged to the long-term MicroMed DeBakey VAD Child in anticipation of heart transplantation The case of our patient shows that high-risk patients who have experienced cardiogenic shock with multiorgan failure and coagulopathy can benefit from the TandemHeart pVAD as a bridge to other therapeutic options, even when creative approaches to treatment and to TandemHeart insertion are required

TL;DR: TandemHeart implan- tation via end-to-side femoral arterial grafting in a cardiac patient whose sepsis and multi-organ failure were complicated by coagulopathy and thromboembolism was discussed in this paper.
Abstract: ® percutaneous ventricular assist device (pVAD), which provides tempo- rary circulatory support of the left ventricle, can be used in high-risk and hemodynamically unstable patients. The easily inserted TandemHeart provides cardiac support superior to that from the use of intra-aortic balloon pumps. Herein, we discuss TandemHeart implan- tation via end-to-side femoral arterial grafting in a cardiac patient whose sepsis and multi- organ failure were complicated by coagulopathy and thromboembolism. A 47-year-old woman, on intra-aortic balloon and intravenous inotropic support after an acute myocardial infarction and emergency coronary artery bypass grafting, was trans- ferred to our institution via helicopter. She developed sepsis and multiorgan failure. Her condition was further complicated by coagulopathy and a left-lower-extremity throm- boembolism. After 6 weeks of aggressive pharmacologic and intermittent intra-aortic bal- loon treatment, the patient developed cardiogenic shock and received a TandemHeart pVAD for short-term circulatory support. A gore -te x ® access graft, sewn end-to-side to the femoral artery because of the patient's leg ischemia and very small vessels, served as a conduit for the TandemHeart's femoral arterial inflow cannula. Her difficult circulatory, anatomic, and coagulopathic status stabilized after 2 weeks of TandemHeart support, and she was bridged to the long-term MicroMed DeBakey VAD ® Child in anticipation of heart transplantation.
TL;DR: The finding that patients with diastolic heart failure should have a reduced UR on reduced Ea and on a report in patients with hypertrophic cardiomyopathy that Dwivedi and colleagues believe showed that peak UR is an …
Abstract: We appreciate the interest of Dwivedi et al in our study.1 They raise 3 points with respect to our results. The first deals with their belief that the untwisting rate (UR) should be abnormal in patients with diastolic heart failure (DHF), the second deals with cardiac function in these patients at rest and with exercise, and the third has to do with the underlying mechanisms.
Dwivedi et al base their impression that DHF patients should have a reduced UR on reduced Ea, on other studies showing abnormal UR, and on a report in patients with hypertrophic cardiomyopathy that Dwivedi and colleagues believe showed that peak UR is an …
