The case of a 27-year-old Japanese woman with type A acute aortic dissection who had been diagnosed with systemic lupus erythematosus (SLE) is presented. The patient also had aortic regurgitation due to non-infective endocarditis and systemic hypertension, and had been maintained on steroid therapy for 15 years. Her twin sister was also diagnosed with SLE. The patient was admitted to emergency due to severe back pain. A chest x-ray showed enlargement of the upper mediastinum. Echocardiography revealed a thickened and deformed aortic valve with aortic regurgitation and dissection of the ascending aorta, but pericardial effusion was not found. Computed tomography demonstrated aortic dissection extending from the ascending aorta to the abdominal aorta. Graft replacement of the ascending aorta and proximal aortic arch was performed under hypothermic circulatory arrest with retrograde cerebral perfusion. The patient recovered uneventfully. Aortic dissection complicated with SLE is extremely rare, and this is only the 15th case reported in the English or Japanese literature.

Alcohol abuse has been linked to intracranial hemorrhage, both intracerebral and subarachnoid. Some studies have found a dose-response relationship, so that increasing levels of abuse are associated with greater risk of hemorrhage. However, alcohol abuse has not been clearly linked to cerebral infarction, and some studies find that mild-to-moderate drinking appears to be associated with a decreased risk of cerebral infarction. Intravenous administration of drugs of abuse predisposes to endocarditis, which may lead to embolic stroke. Associations have been reported between various sympathomimetic drugs and cerebral infarction. A possible mechanism for cerebral infarction is focal arterial vasoconstriction and occasionally cerebral vasculitis. Associations have also been reported between various sympathomimetic drugs and intracranial hemorrhage. A likely mechanism for intracranial hemorrhage is acute arterial hypertension. With the exception of endocarditis, management of stroke related to drug abuse is largely supportive, with emphasis on supportive care to prevent stroke complications, physical and occupational therapy, and aggressive addiction rehabilitation.

A 50-year-old man with a heart murmur from early childhood and a one year history of general fatigue was admitted. Cardiac examination showed a left ventricular-right atrial (LV-RA) communication, and aortic and mitral valve regurgitation (III/IV). At surgery, the LV-RA communication was located in the atrioventricular membranous portion 3 mm above the septal leaflet of the tricuspid valve. The etiology of the LV-RA communication was congenital and valvular diseases were acquired changes caused by sclerosis due to infected endocarditis or hypertension. The diameter of the LV-RA communication defect was 6 mm, and the fibrous tissue around the defect was closed directly. Next, double-valve replacement was performed safely. However, the day after surgery, the patient developed complete atrioventricular block and implantation of a DDD pacemaker was required. He was discharged without other complication. We recommend the careful closure of the LV-RA communication defect, if the defect is small and rich in fibrous tissue.

A 4-year-old boy in whom a muscular ventricular septal defect (VSD) had been diagnosed at birth presented with limited exercise tolerance and mild cardiomegaly. The moderately large defect was closed with an umbrella device via percutaneous heart catheterisation. Thereafter, his symptoms disappeared and the dimensions of the left heart returned to normal. A VSD occurs in 1.5-3.5 per 1,000 live births. In symptomatic patients with a medium or large-sized VSD, surgical closure is indicated to prevent the development of a fixed pulmonary resistance hypertension, ventricular dysfunction and the risk of endocarditis. Depending on the size and localisation of the defect, closure with an umbrella device may be chosen. The initial results have been promising in children. The safety and efficacy in the long term are still unknown.

Coarctation of the aorta is a constriction of the aorta located near the ligamentum arteriosum and the origins of the left subclavian artery. This condition may be associated with other congenital disease. The mean age of death for persons with this condition is 34 years if untreated, and is usually due to heart failure, aortic dissection or rupture, endocarditis, endarteritis, cerebral hemorrhage, ischemic heart disease, or concomitant aortic valve disease in uncomplicated cases. Symptoms may not be present in adults. Diminished and delayed pulses in the right femoral artery compared with the right radial or brachial artery are an important clue to the presence of a coarctation of the aorta, as are the presence of a systolic murmur over the anterior chest,bruits over the back, and visible notching of the posterior ribs on a chest x-ray. In many cases a diagnosis can be made with these findings. Two-dimensional echocardiography with Doppler interrogation is used to confirm the diagnosis. Surgical repair and percutaneous intervention are used to repair the coarctation; however, hypertension may not abate. Because late complications including recoarctation, hypertension, aortic aneurysm formation and rupture, sudden death, ischemic heart disease, heart failure, and cerebrovascular accidents may occur, careful follow-up is required.

HIV infection is a global public health issue that is frequently associated with cardiovascular involvement. These HIV-associated cardiovascular manifestations are often clinically occult or attributed incorrectly to other non-cardiac disease processes. A heightened awareness and routine screening for cardiovascular involvement in HIV-infected patients leads to earlier detection and the hope for a reduction in associated morbidity and mortality. Left ventricular dysfunction, an independent predictor of mortality in HIV-infected patients, is the result of many causes in this population and may result in dilated cardiomyopathy and congestive heart failure in about 10% of patients. Other HIV-associated cardiovascular problems include infective endocarditis, cardiovascular malignancy, pulmonary arterial hypertension, vasculitis, pericardial effusion, premature atherosclerosis, and arrhythmias. HIV-associated cardiovascular emergencies include congestive heart failure, pulmonary edema, supraventricular and ventricular arrhythmias, endocarditis, and tamponade. Anti-infective and immunomodulatory therapies may be particularly helpful in this population to reduce associated cardiovascular disease. Highly active antiretroviral therapy may result in lipodystrophy, hyperlipidemia, truncal adiposity, and insulin resistance that can be improved by physical activity and training programs. Cardiovascular complications of therapeutic drugs in HIV-infected patients include torsade de pointes, congestive heart failure, dyslipidemia, accelerated atherosclerosis, and myocardial infarction. In summary, cardiovascular complications are important contributors to morbidity and mortality in HIV-infected patients that can be detected early in many cases and treated effectively.

Infectious aneurysm is a rare event, especially after the introduction of antibiotic therapy. However, its early detection is very important for timely treatment with antibiotics and surgical intervention. This pathology may generally be due to mycotic endocarditis or septic embolization, prevailing in the preantibiotic era, and to aortitis, whose incidence is actually increasing, mainly in subjects with preexisting large-vessel atherosclerosis and intimal defects. This clinical entity is usually defined as microbial arteritis and recognizes Salmonella spp as the microorganism most frequently isolated from blood or vascular tissue cultures. The authors present the case of a 56-year-old man with a history of hypertension that some weeks before admission manifested as hyperpyrexia and episodic lumbar pain, associated with hepatosplenomegaly and with a pulsing mass in the periumbilical region. Abdominal computed tomography (CT) scan documented a voluminous infrarenal aortic aneurysm with a markedly reduced and irregular vessel wall. The patient underwent surgical excision of the aneurysm, during which marked periaortic inflammation phenomena, complete absence of the posterior aortic wall for a length of 5-6 cm, and the exposure of the correspondent vertebral bodies were observed. Histopathologic examination of the aneurysmal tissue showed atheromatous and thrombotic aspects and confirmed strong signs of inflammation. This case may suggest that the occurrence of microbial aortitis, especially from Salmonella spp, should be taken into account in the presence of a septic status associated with back, abdominal, or thoracic pain.

Survival of patients with aortic coarctation has dramatically improved after surgical repair became available and the number of patients who were operated and reach adulthood is steadily increasing. However, life expectancy is still not as normal as in unaffected peers. Cardiovascular complications are frequent and require indefinite follow-up. Concern falls chiefly in seven categories: recoarctation, aortic aneurysm formation or aortic dissection, coexisting bicuspid aortic valve, endocarditis, premature coronary atherosclerosis, cerebrovascular accidents and systemic hypertension. In this review, these complications, with particular reference to late hypertension, are discussed and strategies for the clinical management of post-coarctectomy patients are described.

This article discusses coarctation of the aorta in the adult. Effective treatments for coarctation have come from surgery since 1945 and from interventional cardiology since 1982. Long-term outcome data are available only for surgical approaches. Thirty-year survival rate is 72% to 82%. Complications include recoarctation or residual coarctation, hypertension, aneurysms at the repair site, spinal cord injury. Other sequelae include bicuspid aortic valve disease, ascending aortic aneurysm, premature coronary disease, and infective endocarditis or endarteritis. Interventional catheter therapy is now the preferred therapy for recurrent coarctation, when the anatomy permits and necessary skills are available. Its use in native or unoperated coarctation is less well established. Treatment may be with balloon angioplasty alone or with a stent. Outcomes are good in skilled hands, but residual or recurrent coarctation with resultant hypertension and repair site aneurysms can occur. Catheter treatment can cause death from aortic rupture and dissection, but mortality compares favorably with surgery if coarctation is recurrent, and perhaps for initial treatment.

The case of a 57-year-old male with a history significant for myeloproliferative disease, chronic renal failure, hypertension, and prostate cancer is described. His complete blood count was remarkable for neutrophilia and, notably, eosinophilia. Subsequent to two syncopal episodes, a transthoracic echocardiogram was performed as part of the workup, which showed an unusual calcified mass in the left ventricular apical region but separate from the apical myocardium, with normal left ventricular systolic function. A transesophageal echocardiogram and computed tomography of the chest confirmed the presence of extensive calcification in the left ventricle of unusual location and shape. This patient probably had Loeffler endocarditis related to myeloproliferative disorder, complicated by calcification of the endocardial sclerotic lesions.
