Aim: To analyze localizations of duplex ultrasonography-diagnosed lower-limb venous thrombosis in young women in hormonal periods in order to optimize the ultrasound exploration., Patients and Methods: From 42,018 standardized ultrasonography report forms, incremented in a database (January 2001 - July 2013), those performed for a first diagnosis of venous thrombosis in women ≤ 45 years were selected (n = 996). Among those, diagnosed venous thrombosis (n = 172) were classified into three groups: oral contraception (n = 74), pregnancy (n = 39) and post-partum period (n = 59). Clinical symptoms and thrombosis distribution were analyzed., Results: In the contraception group, pulmonary symptoms at presentation were much more frequent than in the obstetrical group: 69% vs 20% (P < 0.001). The thrombosis was limited to the iliac veins in 31% (23/74) and to the left internal iliac vein in six patients. During pregnancy, the thrombosis was limited to the iliac veins in 28% (11/39), and to the left internal iliac vein in two patients. In the post-partum period, superficial venous thromboses were found more frequently (37/59). Among the 22 deep venous thromboses, nine were limited to the proximal segment, including four in the vena cava coming from a right ovarian vein thrombosis., Conclusion: Duplex ultrasonography in young women taking oral contraception, as during pregnancy, must target iliac venous segments, especially on the left side, otherwise one thrombosis out of three may be missed; in the post-partum period, the inferior vena cava and superficial veins are to be explored too., (Copyright © 2015 Elsevier Masson SAS.

Aims: To assess whether contractile reserve during dobutamine stress echocardiography (DSE) can predict left ventricular functional recovery in patients with peripartum cardiomyopathy and to assess myocardial fibrosis by magnetic resonance imaging (MRI) in these patients., Methods: Nine patients with peripartum cardiomyopathy were enrolled. All patients underwent DSE and were followed for six months, when a rest Doppler echocardiogram was repeated. MRI was also performed at the beginning of follow-up to identify myocardial fibrosis., Results: Mean age was 29±7.9 years and mean left ventricular ejection fraction at baseline was 39.4±8.6% (range 24-49%). Eight of the nine patients showed left ventricular functional recovery with mean ejection fraction at follow-up of 57.1±13.8%. The ejection fraction response to DSE did not predict recovery at follow-up. On the other hand, left ventricular ejection fraction at baseline correlated with ejection fraction at follow-up. Mild fibrosis was detected in only one patient., Conclusion: Left ventricular ejection fraction at baseline was a predictor of left ventricular functional recovery in patients with peripartum cardiomyopathy. Dobutamine stress echocardiography at presentation of the disease did not predict recovery at follow-up. Myocardial fibrosis appeared to be uncommon in this cardiomyopathy., (Copyright © 2011 Sociedade Portuguesa de Cardiologia. Published by Elsevier España. All rights reserved.)

Peripartum cardiomyopathy (PPCM) is a rare disorder of dilated cardiomyopathy and left ventricular dysfunction occurring in the last month of pregnancy or within 5 months postpartum. Outcome of PPCM is highly variable, comprising clinical improvement and rapid deterioration unresponsive to medical treatment requiring heart transplantation or even death. In this study, we report the clinicopathologic findings of 10 patients with PPCM who were retrospectively identified in our cardiomyopathy registry. During a follow-up of 69+/-27 months, no patient died or required orthotopic heart transplantation. Left ventricular ejection fraction was 38+/-7% at the time of diagnosis and 53+/-7% during follow-up. While all patients had sinus rhythm at the time of diagnosis, three patients presented with left bundle branch block. We found no evidence of viral infection in endomyocardial biopsy samples of seven patients by PCR. Histopathologic findings revealed the presence borderline myocarditis in two of seven patients (29%). Circulating autoantibodies to cardiac tissue of any kind were observed in all patients. In conclusion, in our retrospective observational study, no patient diagnosed with PPCM died or received orthotopic heart transplantation. Improvement of left ventricular ejection fraction was present in eight patients (80%), while LV dysfunction persisted in four patients. Our findings support the hypothesis of an underlying autoimmune pathomechanism in this rare disease.

Purpose: Pregnancy and the puerperium are time periods of an increased risk for venous thromboembolism. An ideal treatment should lead to complete restoration of the venous lumen, elimination of the embolic source, and prevention of severe postphlebitic syndrome. Anticoagulation therapy with heparin or thrombectomy are treatment options. In the current literature, these options are discussed controversially., Methods: From January 1982 to December 2001, 97 women underwent (93% transfemoral) thrombectomy and construction of an arteriovenous fistula (AVF) for deep venous thrombosis related to pregnancy. The clinical and coagulation parameters were evaluated. The AVF was ligated 3 to 6 months later. Follow-up with duplex ultrasound scan, photoplethysmography, and strain-gauge plethysmography was completed in 87 women., Results: Surgery was performed without any maternal death or pulmonary embolization. A cesarean section was carried out during the same anesthesia in 11 cases. Thrombectomy was completed with construction of a temporary AVF in 90 patients (92.8%). One fetal death occurred in the recovery room for unknown reasons. In the early postoperative course, 16 patients (16.5%) underwent redo surgery for rethrombosis with or without the occlusion of the fistula. In 14 of these patients, the venous system remained patent thereafter. Fetal or neonatal death occurred in five cases 2 to 10 weeks after surgery, mainly because of abruption of the placenta probably from anticoagulation. Among 247 preoperatively occluded anatomic regions, 221 could be restored, and the secondary patency rate amounted to 89.5%. After a mean follow-up period of 6 years, 49 patients (56.3%) were seen without a postphlebitic syndrome, and only three patients (3.5%) had had a leg ulcer develop., Conclusion: In experienced hands, venous thrombectomy is a safe method to prevent pulmonary embolism and postphlebitic syndrome in women during pregnancy and the puerperium. The frequency of a severe postphlebitic syndrome after our surgical approach is lower than the rates published for anticoagulation treatment alone.

Unlabelled: Cerebrovascular diseases are the main causes of neurological events occurring during pregnancy and puerperium., Methods: We retrospectively reviewed the clinical records and imaging scans of females presenting with stroke during pregnancy or puerperium. We selected the cases with abnormal initial CT and/or MRI and a radiological follow-up until stabilization of the neurological condition., Results: Eleven patients with ages ranging from 21-38 years were found. The hospital admission occurred between the second trimester of pregnancy and the first two weeks after delivery. In six cases there was a clinical setting of preeclampsia/eclampsia (PE/E): five with reversible encephalopathy syndromes (hypertensive-like encephalopathy) and one with a hematoma in a HELLP patient. Three other cases had a clinical setting of hypertension, not fulfilling the PE/E criteria, presented with hemorrhagic infarct in one case and lenticular hematoma in the other two. The other two cases were a subarachnoid hemorrhage in a patient with a middle cerebral aneurysm and a cortical venous infarct in a patient with lateral sinus thrombosis., Conclusion: Hypertension is the major underlying factor in peri-partum stroke. PE/E syndrome is the major leading cause of stroke in the peri-partum and maternal morbidity/mortality. MRI is very useful in evaluating this entity and, may have a positive impact on the management protocol.

Peripartum cardiomyopathy is a devastating medical condition and carries a mortality of up to 60% with medical treatment. The authors describe their experience of successful outcome of three cases with heart transplantation and review the literature. The importance of performance of endomyocardial biopsy for all peripartum cardiomyopathy patients is emphasized. It is recommended that heart transplantation should only be offered to myocarditis negative patients.

We report the case of a 22-year-old woman suffering from peripartum cardiomyopathy who was successfully bridged to cardiac transplantation with a Novacor left ventricular assist device (LVAD). Her course with the device is presented and emphasis is put on the size mismatch between the patient and the device, a fact with normally precludes the implantation of the Novacor LVAD.

The authors reported the case of a 26 year-old primipara who had unexplained congestive cardiac failure on the 9th week after delivery. There was no previous disease in her history however her pregnancy endangered because of imminent abortion was preceded by 1 artificial and 2 spontaneous abortions. In the acute phase she had to be resuscitated because of ventricular fibrillation and then she had a pulmonary embolism followed by pneumonia and therefore she was in septic state for 4 weeks. After a 4 month clinical remission she died unexpectedly at home. At autopsy the histological appearance of myocarditis, thymic hyperplasia and hypoplastic vascular system were observed.

Peripartum cardiomyopathy (PC), an uncommon cause of peripartum heart failure, is defined as a cardiomyopathy presenting in the last trimester of pregnancy or the first 6 months postpartum, without evidence of preexisting cardiovascular disease. The etiology of PC and idiopathic dilated cardiomyopathy (IDC) remains uncertain. Several reports have addressed possible differences in clinical presentation and prognosis between these groups. A relatively high incidence of myocarditis has been recently reported in patients with PC, raising the possibility that this may represent a distinct difference between this condition and IDC. A retrospective review of endomyocardial biopsy specimens from 34 patients fulfilling the criteria for a diagnosis of PC was therefore performed to further evaluate this finding. Results indicate a lower incidence of myocarditis (8.8%, 3 of 34) than that reported in other studies. This incidence was comparable to that found in an age- and sex-matched control population undergoing transplantation for IDC (9.1%, 2 of 22). Factors that may influence the diverse range in the reported incidence of myocarditis are discussed.

We report the case of a 28-year old asthmatic female patient, who developed an acute heart failure beginning with diarrhea, fever, and dyspnea 5 weeks after delivery. After improvement of all vital functions and dismissal from hospital care unit a marked blood hypereosinophilia, left ventricular congestive heart failure, pericardium effusion and fever up to 40 degrees C followed. Endomycardial, bone marrow and skeletal muscle biopsies and the pericardial fluid showed a marked eosinophilic infiltration or polymyositis, respectively, which could be treated successfully with steroids and azathioprin. During steroid medication cytomegalovirus-associated myocarditis developed and was diagnosed by in situ hybridization. CMV hyperimmunoglobulin treatment (Cytotect, Biotest) was started (2 ml/kg bw on day 1 and 3, and 1 ml/kg on days 5, 7 and 9), which led to the eradication of the residual infiltrate and CMV-DNA in the myocardium. After discontinuation of all medication, eosinophilia and asthma recurred so that immunosuppressive treatment was continued.

Clinicopathologic features of 13 women with peripartum cardiomyopathy were compared to 13 women aged 19 through 38 with idiopathic dilated cardiomyopathy. No presenting clinical or pathologic variable distinguished either group. However, the clinical course differed between the groups. Eleven of 13 patients with idiopathic dilated cardiomyopathy had a poor clinical outcome, defined as persistent heart failure or death. Patients in this group succumbed one year or more after disease onset. Five of 13 patients with peripartum cardiomyopathy had poor outcome, with death occurring 9 months or less after disease onset. The clinical course of peripartum cardiomyopathy appears distinct from that of idiopathic dilated cardiomyopathy in young women.

Peripartum cardiomyopathy is defined as left ventricular dilation and failure, first developing during the third trimester of pregnancy or in the first 6 months postpartum. In an effort to characterize this syndrome in a middle class population, 14 consecutive patients with peripartum cardiomyopathy underwent a detailed history and physical examination, right heart catheterization, M-mode and two-dimensional echocardiography, radionuclide ventriculography and right ventricular endomyocardial biopsy. These patients were then observed with sequential noninvasive studies to determine prognostic indicators. Eight (57%) of these 14 patients were primiparous and an equal number first presented with heart failure concomitant with or immediately before the onset of labor. When these women were compared with 55 patients with idiopathic dilated cardiomyopathy, only mean age at onset of symptoms (28.7 +/- 5.7 versus 48.2 +/- 13.6 years, p less than 0.001) and symptom duration (4.1 +/- 7.7 versus 19.0 +/- 18.4 months, p less than 0.001) differed between the groups. There was no difference in ventricular arrhythmia, left ventricular chamber size, ejection fraction or hemodynamics. Myocyte histologic findings were similar; however, myocarditis was identified in 29% of patients with peripartum cardiomyopathy and in only 9% of those with idiopathic dilated cardiomyopathy. In all patients with peripartum cardiomyopathy and myocarditis, the myocardial biopsy was performed within 1 week of onset of symptoms. Seven (50%) of the patients with peripartum cardiomyopathy had dramatic improvement within 6 weeks of follow-up, and 6 (43%) died.(ABSTRACT TRUNCATED AT 250 WORDS)

According to Schnitker, Mandel, Hirst and their associates, approximately half of the dissecting aneurysms in women under 40 years of age are associated with pregnancy. This significant relationship between dissecting aneurysm and pregnancy has been discussed by considering hemodynamic stress and also the hormonal changes of pregnancy. In this report, we describe five patients with dissecting aneurysm during pregnancy or the puerperium, review the literature and discuss the influence of pregnancy on the pathogenesis of this disease.
