This report reviews the present status of cardiovascular surgery in West Africa and highlights some of the constraints of development in this field.Rheumatic heart disease is still endemic in the tropics, where it constitutes about 20 percent of all cases of cardiovascular disease (CVD) in Nigeria. Endomyocardial fibrosis is a disease of unknown etiology accounting for 10 to 20 percent of cases. Purulent pericarditis is a common complication of pyomyositis and osteomyelitis found in 5 percent of patients. Chronic constrictive pericarditis is a sequela of infective pericarditis found in 5 percent of all cases of CVD. Calcification is found in 30 percent of cases and pericardiectomy can be performed successfully without cardiopulmonary bypass. Infective endocarditis is equally rare, occurring in 2.5 percent of cases; it is a common source of septic emboli to coronary artery and a very difficult disease to treat in the West African environment.Ischemic heart disease is relatively uncommon, accounting for less than 0.5 percent of patients. The rarity of the disease in black Africans has been attributed to dietary habits and environment rather than to racial and psychosocial factors. Congenital heart disease accounts for 5 percent of all cases of CVD in this review. Ventricular septal defect and patent ductus arteriosus are the most common acyanotic defects, while tetralogy of Fallot and transposition of the great arteries are the most common cyanotic defects.Vascular diseases are uncommon in this series, with traumatic injuries accounting for most of the cases. Abdominal aortic aneurysms, peripheral occlusive vascular disease, and atherosclerotic aortic aneurysms are quite rare. This review further confirms the rarity of deep venous thrombosis and pulmonary embolism in Africans.

The eustachian valve is an embryological remnant of the inferior vena cava valve that is absent or inconspicuous in the adult. Even when prominent, it is considered to be a benign finding. The present report describes a patient with deep venous thrombosis who had recurrent pulmonary embolism despite thrombolysis and anticoagulation. He was found to have an adherent thrombus on the eustachian valve and his symptoms resolved completely following surgical thrombectomy. The present report highlights that the eustachian valve can, on rare occasions, harbour pathology and can adversely impact the outcomes of coexisting medical problems such as deep venous thrombosis. Infective endocarditis, pulmonary embolism and systemic embolism via a patent foramen ovale are the major complications of eustachian valve pathology. Transesophageal echocardiography appears to be superior to transthoracic echocardiography in identifying eustachian valve pathology and should be considered in all patients with thromboembolism without a known source.

A 66-year-old woman with a history of tissue aortic valve replacement and chronic back pain presented to the emergency department with a suspected right leg deep vein thrombosis. A recent outpatient MRI had revealed discitis. A ventricular fibrillation cardiac arrest occurred in the emergency department. Cardiac output was restored on the fifth defibrillation. A transthoracic echocardiogram showed large aortic valve vegetations. Clinical impression was of infective endocarditis with cardiac arrest secondary to coronary artery embolisation. Peripheral blood cultures grew Cardiobacterium hominis, and appropriate intravenous antibiotic therapy was administered. The infected prosthetic valve was excised. The patient experienced postoperative complete heart block and a right hemisphere cerebrovascular accident, however she is now recovering well. This case describes an unusual case of infective endocarditis secondary to C. hominis, with disc, leg, coronary artery and brain septic embolisation. Infective endocarditis is an important differential diagnosis in multisystem presentations.

Infective endocarditis (IE) is a life-threatening condition with adverse consequences and increased mortality, despite improvements in treatment options. Diagnosed patients usually require a prolonged course of antibiotics, with up to 40-50% requiring surgery during initial hospital admission. We report a case of a 42-year-old intravenous drug user who presented feeling generally unwell, with lethargy, rigours, confusion and a painful swollen right leg. He was subsequently diagnosed with Proteus mirabilis endocarditis (fulfilling modified Duke criteria for possible IE) and deep vein thrombosis (DVT). He was successfully treated with single antibiotic therapy without needing surgical intervention or requiring anticoagulation for his DVT. Proteus endocarditis is extremely uncommon, with a limited number of case reports available in the literature. This case illustrates how blood cultures are invaluable in the diagnosis of IE, especially that due to unusual microorganisms. Our case also highlights how single antibiotic therapy can be effective in treating Proteus endocarditis.
