Pulmonary hypertension in pregnancy has been associated with negative maternal and fetal outcomes over the past decades. With the emergence of novel treatment modalities, morbidity and mortality of women who have pulmonary hypertension in pregnancy have improved. In this review, we aim to explore the contemporary updates in the management of pre-capillary and post-capillary pulmonary hypertension in pregnancy.

INTRODUCTIONPeripartum cardiomyopathy (PPCM) is a rare but life-threatening condition. We report 11 patients admitted to the National Heart Centre Singapore with a diagnosis of PPCM over a period of 14 months.

METHODSBaseline demographics, pregnancy history, haematology, serum biochemistry and echocardiographic findings of women admitted with a diagnosis of PPCM were analysed.

RESULTSThe incidence of PPCM was 0.89 per 1,000 live births in our cohort. 63.6% of the patients were Malay and 27.3% were Chinese. 45.5% of the patients were smokers and 45.5% had a history of pregnancy-induced hypertension or preeclampsia. There was no maternal mortality. Mean left ventricular ejection fractions at diagnosis and at six months were 26.9% ± 9.1% and 51.9% ± 10.6%, respectively. Mean left ventricular internal diameters in end-diastole at diagnosis and at six months were 5.5 ± 0.5 cm and 5.1 ± 0.6 cm, respectively. All patients were treated successfully for the acute episode and all but one patient had returned to New York Heart Association functional class I status at six months.

CONCLUSIONPPCM remains a rare condition and appears to occur more commonly in Malay patients. Smoking and pregnancy-induced hypertension appear to be significant risk factors. While short-term outcome remains excellent, collaborative studies with other tertiary centres will help enhance our understanding of the long-term management of and clinical outcomes in these patients.

Aortic dissection accompanying with preeclampsia during pregnancy can be lethal to both the mother and the fetus and carries a high mortality. Of the 2 preeclampsia patients with aortic dissection, one was Type B aortic dissection, occurring in postpartum period. The patient was treated medically and underwent catheter-based stent-graft treatment with fenestration technique. Another patient was Type A acute dissection, occurring in the third trimester. This patient was undiagnosed and both died. Although extremely rare, aortic dissection might be a possibility in preeclampsia pregnant women, the differential diagnosis of chest and/or epigastric pain in preeclampia patient should be thoroughly investigated and treated.

Peripartum cardiomyopathy (PPCM) is a rare but serious form of cardiac failure affecting women in the last months of pregnancy or early puerperium. Clinical presentation of PPCM is similar to that of systolic heart failure from any cause, and it can sometimes be complicated by a high incidence of thromboembolism. Prior to the availability of echocardiography, diagnosis was based only on clinical findings. Recently, inclusion of echocardiography has made diagnosis of PPCM easier and more accurate. Its etiopathogenesis is still poorly understood, but recent evidence supports inflammation, viral infection and autoimmunity as the leading causative hypotheses. Prompt recognition with institution of intensive treatment by a multidisciplinary team is a prerequisite for improved outcome. Conventional treatment consists of diuretics, beta blockers, vasodilators, and sometimes digoxin and anticoagulants, usually in combination. In resistant cases, newer therapeutic modalities such as immunomodulation, immunoglobulin and immunosuppression may be considered. Cardiac transplantation may be necessary in patients not responding to conventional and newer therapeutic strategies. The role of the anesthesiologist is important in perioperative and intensive care management. Prognosis is highly related to reversal of ventricular dysfunction. Compared to historically higher mortality rates, recent reports describe better outcome, probably because of advances in medical care. Based on current information, future pregnancy is usually not recommended in patients who fail to recover heart function. This article aims to provide a comprehensive updated review of PPCM covering etiopathogeneses, clinical presentation and diagnosis, as well as pharmacological, perioperative and intensive care management and prognosis, while stressing areas that require further research.

INTRODUCTIONAtherosclerotic coronary artery thrombosis is the most common cause of acute myocardial infarction.

CLINICAL PICTUREA 30-year-old lady presented with acute peripartum massive anterior ST segment myocardial infarction and cardiogenic shock. This was due to acute Stanford type A aortic dissection with the intimal flap occluding the left coronary ostium. The initial diagnosis was not apparent. Echocardiography confirmed the diagnosis.

TREATMENT AND OUTCOMEShe underwent emergency surgical repair (Bentall procedure). Pathology confirmed underlying idiopathic cystic medial degeneration.

CONCLUSIONA high index of clinical suspicion is required in acute myocardial infarction presenting without traditional cardiovascular risk factors.

OBJECTIVETo analyze the clinical characteristics of peripartum cardiomyopathy and to evaluate the different factors that influence the prognosis of the peripartum cardiomyopathy.

METHODA retrospective review was undertaken on records of women who were diagnosed with peripartum cardiomyopathy at Peking Union Medical College Hospital between Jan. 1983 and May 1999.

RESULTSDuring the research period, only 16 pregnant women were documented as peripartum cardiomyopathy. Some of the women undertook ultrasonic cardiographic (UCG) examination that showed decreased systolic function. Seven women were complicated with pregnancy induced hypertension. Three died of disseminated intravascular coagulation, embolism and cardiogenic shock respectively.

CONCLUSIONEarly diagnosis of the peripartum cardiomyopathy is extremely important. The UCG can provide helpful information on disease progression or regression.

OBJECTIVETo investigate the high risk factors, clinical features, diagnosis and treatment of pulmonary embolism (PE) during pregnancy and the postpartum period.

METHODSTwo cases of PE during pregnancy and postpartum period were reported retrospectively.

RESULTSThe first case was a pregnant woman with congenital heart disease at 39-week gestation. She underwent a successful cesarean section (CS) because of heart disease, but she manifested tachycardia, tachypnea, cyanosis, and dyspnea suddenly on the 10th day after CS and died soon after the onset of these symptoms. The diagnosis of PE was highly suspected clinically. The second case was a twin-pregnancy woman at 35-week gestation. Because of severe perinatal myocardiopathy, cesarean section was performed. Unfortunately, the patient died abruptly on the operation table. The diagnosis of PE was confirmed by autopsy.

CONCLUSIONSThe maternal mortality of PE during pregnancy and postpartum period is quite high. Whenever there is any doubt, objective examinations for PE should be started early in order to strive for the chances of the anticoagulant therapy.
