ABSTRACT
OBJECTIVES: Hypertensive disorders of pregnancy (HDP) are among the leading causes of maternal morbidity and mortality. The primary objective of this study was to ascertain whether maternal cardiac remodeling is more prevalent in HDP than normotensive pregnancy and if significant change in aortic root size is involved. The secondary objective was to determine the types of cardiac remodeling often associated with HDP. METHODS: A systematic search was conducted across four electronic databases, including Medline, PubMed, Cochrane and EMBASE. The reference lists of selected articles were also searched to ensure no relevant studies were missed. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed in this systematic review. RESULTS: Out of 5,278 articles identified by the search terms, 9 were eligible for inclusion in the meta-analysis. The investigation unveiled a greater prevalence of maternal cardiac remodeling in HDP than normotensive pregnancies. The commonest type of maternal cardiac remodeling in both HDP and normotensive pregnancies was eccentric left ventricular hypertrophy, followed by concentric left ventricular remodeling which was more specific to HDP. Notably, left atrial diameter was significantly increased in HDP than normotensive pregnancies, suggesting higher prevalence of diastolic dysfunction. Additionally, the aortic root dimension was significantly increased in HDP than normotensive pregnancies. CONCLUSION: This study underscores the importance of monitoring cardiac health in pregnancy, particularly in those with hypertensive disorders, in order to mitigate potential complications and improve maternal outcomes. Finally, the risk of aortic dissection that may occur as a long-term effect of aortic root enlargement in women with history of HDP ought to be investigated in future studies.

Acute aortic dissection in unusual/rare circumstances may become chronic and multi lumen. A high clinical acumen, examination and investigations in the acute setting, may help reduce late/misdiagnosis and complications in low resource settings.
ABSTRACT
Marfan syndrome (MFS) is an autosomal dominantly inherited condition that has varying phenotypic expressions. This case report describes one such African patient, from Ghana, who had typical clinical and imaging traits of MFS but was first diagnosed incidentally at the age of 23 years. In this report, we explore the challenges of early diagnosis in this population.
ABSTRACT
BACKGROUND: Immune thrombocytopenic purpura is a condition associated with an unusual, unexplained, and sometimes very severe reduction in the level of platelets in the blood. Though documented, its association with Graves' disease is not very common and can easily be missed or misdiagnosed, leading to excessive bleeding and mortality. Treatment with steroids and antithyroid medications has been shown to be beneficial in correcting thrombocytopenia in these patients, although the response is varied. We report on a patient with Graves' disease who presents with immune thrombocytopenic purpura. CASE PRESENTATION: A 37-year-old Ghanaian female presented to our hospital's emergency department with a complaint of palpitations, difficulty breathing, easy fatigue, and headaches. She had been referred from a peripheral hospital as a case of thrombocytopenia, severe anemia, and anterior neck swelling. She was diagnosed with Graves' disease 2 years ago, became euthyroid during treatment, but defaulted. On further examination and investigation, she was diagnosed with immune thrombocytopenic purpura and was also found to have elevated free T3 and T4, and suppressed thyroid stimulating hormone. She also had high thyroid autoantibodies. She was initially started on oral prednisolone but there was no stabilization of platelets until methimazole was introduced, which improved and normalized her platelet count. CONCLUSION: The association of Graves' disease with immune thrombocytopenic purpura, though documented, is uncommon, and very few cases have been reported thus far. There have not been any reported cases in Ghana or Sub-Saharan Africa and hence, clinicians should be aware of this association when investigating immune thrombocytopenic purpura and should consider Graves' disease as a possible cause. From this study, we observed that there was no improvement in platelet count following the use of corticosteroid therapy until methimazole was started.

BACKGROUND: Heart failure (HF) is recognized as a global public health disease associated with high morbidity and mortality. It is suggested that the main underlying causes of HF in developing countries differ from those identified in well-resourced countries. This study therefore presents the cardiovascular risk factors and the underlying aetiology of HF among admitted patients in a teaching Hospital in Ghana. METHOD: The study prospectively recruited 140 consecutive patients admitted for heart failure at the Medical department of the Korle-Bu Teaching Hospital from March to October, 2014. The study evaluated the cardiovascular risk factors and the aetiologies of heart failure, and compared the risk factors and aetiologies with patient's age and gender. RESULTS: The mean age of the study participants was 51.3 ± 16.8 years. The commonest cardiovascular risk factors observed were hypertension (46.5%), history of previous HF (40.7%), excessive alcohol use (38.6%), and family history of heart disease (29.3%); predominantly hypertension (68.3%). The major underlying aetiology of HF were dilated cardiomyopathy (38.6%), hypertensive heart disease (21.4%), ischaemic heart disease (13.6%) and valvular heart disease (12.9%). These underlying aetiology of HF were more common in patients aged 40 years and above (p = 0.004) and those presenting with multiple risk factors (p = 0.001). CONCLUSION: The major underlying aetiology of heart failure in adults were dilated cardiomyopathy, hypertensive heart disease, ischaemic heart disease and valvular heart disease, which were significantly high among patients aged 40 years and above and those presenting multiple risk factors. Hypertension, excessive alcohol use, family history of heart disease and personal history of previous heart failure diagnosis are noted as the main cardiovascular risk factors among heart failure patients.

OBJECTIVES: This study set out to identify significant lesion features of chronic total occlusion (CTO) that predict successful retrograde recanalization via epicardial collateral channels (CCs). BACKGROUND: Epicardial CCs remain essential in retrograde percutaneous coronary intervention (PCI) of CTO. However, the unpredictability of success and occurrence of complications limit the application of epicardial CCs for retrograde PCI technique for CTO. METHODS: 103 retro-recanalization cases were analyzed using epicardial CCs with successful recanalization as an end point. Clinical and angiography data were collected. RESULTS: The total success rate was 76.3%. Independent predictors associated with technical success included CCs tortuosity, side branch at CCs tortuosity, inadequate CCs Size and inadequate CCs exit location. Assigning a score of one for each variable, four levels of difficulty were obtained and formed the EPI-CTO score (Epicardial CTO). This score had significant predictive value for the likelihood of successful recanalization (AUC: 0.94, 95%CI: 0.89-0.98). Coronary and CCs perforation occurred in 6 and 10 cases respectively. Four cases including two coronary and two CCs perforations had tamponade that needed pericardiocentesis. CONCLUSIONS: Using epicardial CCs for retrograde approach of CTO PCI is effective. Complication rate was acceptable. We found four independent predictors relative to procedure success.
