Peripartum cardiomyopathy is a rare cause of dilated cardiomyopathy in parturients, occurring in approximately one in 1000 deliveries, manifesting during the last few months or the first 5 months of the postpartum period. It can result in severe ventricular dysfunction during late puerperium. The major concern while managing these patients is to optimize fluid administration and avoid myocardial depression, while maintaining stable intraoperative hemodynamics. We present a case series of five parturients that were posted for elective cesarean section and managed successfully by the epidural volume extension technique.

Miocardiopatía periparto aguda y críticamente enfermo y 'puente' de opciones terapéuticas: experiencia con bomba de balón intra-aórtico, oxigenación por membrana extracorpórea y dispositivos de flujo continuo para asistencia ventricular izquierda.

Acute and critically ill peripartum cardiomyopathy and 'bridge to' therapeutic options: a single center experience with intra-aortic balloon pump, extra corporeal membrane oxygenation and continuous-flow left ventricular assist devices.

Peripartum cardiomyopathy (PPCM) patients refractory to medical therapy and intra-aortic balloon pump (IABP) counterpulsation or in whom weaning from these therapies is impossible, are candidates for a left ventricular assist device (LVAD) as a bridge to recovery or transplant. Continuous-flow LVADs are smaller, have a better long-term durability and are associated with better outcomes. Extra corporeal membrane oxygenation (ECMO) can be used as a temporary support in patients with refractory cardiogenic shock. The aim of this study was to evaluate the efficacy and safety of mechanical support in acute and critically ill PPCM patients. METHODS:
This was a retrospective search of the patient database of the Ghent University hospital (2000 to 2010). RESULTS: Six PPCM-patients were treated with mechanical support. Three patients presented in the postpartum period and three patients at the end of pregnancy. All were treated with IABP, the duration of IABP support ranged from 1 to 13 days. An ECMO was inserted in one patient who presented with cardiogenic shock, multiple organ dysfunction syndrome and a stillborn baby. Two patients showed partial recovery and could be weaned off the IABP. Four patients were implanted with a continuous-flow LVAD (HeartMate II, Thoratec Inc.), including the ECMO-patient. Three LVAD patients were successfully transplanted 78, 126 and 360 days after LVAD implant; one patient is still on the transplant waiting list. We observed one peripheral thrombotic complication due to IABP and five early bleeding complications in three LVAD patients. One patient died suddenly two years after transplantation. CONCLUSIONS: In PPCM with refractory heart failure IABP was safe and efficient as a bridge to recovery or as a bridge to LVAD. ECMO provided temporary support as a bridge to LVAD, while the newer continuous-flow LVADs offered a safe bridge to transplant.


Miocardiopatías atípicas inducidos por el estrés transitorios con un patrón takotsubo invertido en la sepsis y en el estado post-parto.

Atypical transient stress-induced cardiomyopathies with an inverted Takotsubo pattern in sepsis and in the postpartal state.

Several cases of inverted Takotsubo cardiomyopathy--a variant form with hyperdynamic left ventricular apex and akinesia of the left ventricular base and mid-portion--have been reported recently, especially in association with cerebrovascular accidents and catecholamine cardiomyopathies. Herein, we describe 2 cases of inverted Takotsubo cardiomyopathy: one that occurred in a middle-aged woman who had a septic condition, and another in a young woman who was in the postpartal state. Such cases have not been reported previously.KEYWORDS:Cardiomyopathies/physiopathology/therapy/ultrasonography; coronary angiography; echocardiography; heart ventricles/physiopathology/radiography; postpartum period; sepsis; ventricular dysfunction, left; ventricular dysfunction/diagnosis/physiopathology
