Marfan syndrome is associated with a high incidence of aortic root aneurysm and life-threatening aortic dissection. With the successful use of surgical aortic root replacement, dissection-related mortality has been significantly reduced. We present the case of a patient with Marfan syndrome who presented with heart failure secondary to an unusual ...

BackgroundIn patients with hypertrophic cardiomyopathy (HCM) an impaired microvascular function is reported not only in the hypertrophied septum but also in the nonhypertrophied left ventricular free wall as well as in forearm resistance vessels, thus suggesting a generalized alteration in vascular function. However, information on conduit artery involvement is still ...

Congenital arteriovenous malformations are a well-described cause of neonatal heart failure. Fistulous connections are typically intrahepatic or intracranial. We present a case of a neonate with an intrathoracic arteriovenous malformation between the subclavian artery and superior vena cava resulting in florid neonatal heart failure. This unusual fistulous connection has only ...

A 3-month-old infant with perimembranous ventricular septal defect (VSD) and pulmonary hypertension presented at our center. Cardiac catheterization showed a systolic pulmonary-to-systemic arterial pressure ratio of 0.99 and a pulmonary vascular resistance of 9.32 μm(2). Pulmonary angiography showed focal orifice stenosis in the right lower and left lower and upper ...

Aneurysms of the major thoracic veins are rare. They are usually asymptomatic and thus treated conservatively. We report an extremely rare case of rapidly progressing superior vena cava (SVC) aneurysm complicated by thrombosis and acute pulmonary thromboembolism (PTE) with right ventricular dysfunction. Thrombolytic therapy for hemodynamically significant acute PTE was ...

Myogenic tone, an important regulator of vascular resistance, is dependent on vascular smooth muscle (VSM) depolarization, can be modulated by endothelial factors, and is increased in several models of hypertension. Intermittent hypoxia (IH) elevates blood pressure and causes endothelial dysfunction. Hydrogen sulfide (H(2)S), a recently described endothelium-derived vasodilator, is produced ...

Three cases are reported to demonstrate the range of possible lesions and wide variation in lethal mechanisms that may be found in cases of unexpected death subsequently shown to be due to bacterial endocarditis. Case 1: A 36-year-old man was found dead on his bedroom floor surrounded by drug paraphernalia. ...

The MSCT manifestations of a left coronary artery-to-right atrium fistula before and after the transcatheter closure were reported. Before treatment, MSCT showed a dilated left coronary sinus and the dilated left main trunk, which coursed along the coronary sulcus to form the left circumflex artery, draining directly into the right ...

A 20-year-old woman complained for several weeks before her death of unspecific epigastric pains. Such episodes were labeled as "dyspeptic episode." A month later, once again she started to complain about stomach pains, then she collapsed unconscious. She was rushed to a hospital, where she was admitted in cardiorespiratory arrest. ...

Isolated aneurysms of the iliac artery (IA) are very rare. Inflammatory aneurysms are also rare conditions, making the association rarer. Only four cases of isolated inflammatory IA aneurysms have been reported in the last decade. In this article, we report a case of a 62-year-old patient with a 13-cm large ...

Patients who have undergone cardiac transplantation are occasionally complicated by the development of a coronary artery fistula. It has been reported that a majority of coronary artery fistulas in a post-heart transplant setting communicate with the right ventricle. Moreover, most had a favorable prognosis and were rarely associated with hemodynamic ...

Background/Aims: Evidence suggests that vascular calcification (VC) portends poor cardiovascular (CV) prognosis in patients undergoing maintenance dialysis (CKD-5). Nonetheless, how VC might predispose to CV mortality still remains to be clarified. Herein, we report on the association between coronary artery calcification (CAC) progression and changes in cardiac repolarization as well ...

Hyper-IgE syndrome (HIES) is a rare primary immunodeficiency caused by autosomal dominant STAT3 mutations resulting in recurrent infections and connective tissue abnormalities. Coronary artery abnormalities have been reported infrequently. We aimed to determine the frequency and characteristics of coronary artery abnormalities. STAT3-mutated HIES patients (n=38), ranging in age from 8 ...

We examined mechanisms by which hypoxia may elicit pulmonary capillary recruitment in humans. On separate occasions, twenty-five healthy adults underwent exposure to intravenous saline infusion (30 ml/kg ∼ 15 min) or 17-h normobaric hypoxia ( [FIO2 = 12.5%). Cardiac output (Q) and pulmonary capillary blood volume (Vc) were measured before ...

Suture-mediated closure devices have been previously described as an interesting alternative to femoral cutdown during endovascular aortic procedures. The insertion of two or three devices before the cannulation (preclose technique) permits successful percutaneous access also with a large sheath up to 24 Fr diameter. The main benefit of percutaneous access ...

Rationale: Vascular smooth muscle cell (VSMC) proliferation and migration are crucial events involved in the pathophysiology of vascular diseases. Sirtuin 1 (SIRT1), a class III histone deacetylase (HDAC), has been reported to have the function of antiatherosclerosis, but its role in neointima formation remains unknown. Objective: The present study was ...

Paradoxical embolism is the result of systemic arterial embolism and pulmonary embolism. It indicates the presence of an intracardial defect in the area of the atrial or ventricular septum. The most frequent cause of an intracardiac defect associated with paradoxical embolism is a patent foramen ovale (PFO). In the case ...

Thromboembolic disease is a potentially severe pathology, which can represent a life threat if it is not diagnosed early, especially when the cardiopulmonary backup is limited. When its clinical feature implies a massive occlusion of the arterial pulmonary tree and a cardiac failure is ensued, it can be seriously life ...

We report an unusual case of congenital giant coronary aneurysm. A 23 year old male with a history of acute myocardial infarction presented an abnormal shadow in the left cardiac border on routine X-ray.

When the bilateral internal thoracic arteries are grafted to the left coronary arteries, it remains controversial whether the better conduit is provided by grafting the saphenous vein graft (SVG) or the gastroepiploic artery (GEA) to the right coronary artery territory. From the beginning of the present study, we consistently used ...

A 37-year-old woman who sustained blunt chest trauma as a result of a car accident was found unconscious at the accident site with signs of circulatory compromise. Computed tomographic trauma screening excluded thoracic, intracranial, and intra-abdominal bleeding, or other pathologic findings, except a small circumferential hemopericardium. Echocardiography revealed a hemopericardium ...

The management of pulmonary hypertension has already incorporated the use of multiple therapies into routine practice. Available therapies act principally through vasodilatation of the pulmonary arterial circulation through well-delineated mechanisms, although right ventricular function determines function and prognosis. Therefore, the goal of these therapies is effectively to preserve right ventricular ...

Successful anatomical repair in congenitally corrected transposition of the great arteries depends on adequate re-routing of the atrial venous pathways. Abnormal positioning of the heart or abnormal venous drainage, or both, can impair access to the atrial pathways and previous palliative procedures can further complicate the reconstruction required to achieve ...

Abstract The present article will review new technology in the invasive approach to mitral valvular disease. Mitral valve pathology continues to present an important challenge to the cardiac surgeon and interventionalist. From the early days of closed mitral valvular commisurotomy, a number of new approaches to this valve have been ...

The 6-minute walk test is a useful tool to assess functional outcome after pulmonary endarterectomy (PEA) in chronic thromboembolic pulmonary hypertension. However, little is known about the longitudinal dynamics in functional improvement. We performed a longitudinal follow-up of 6-minute walk distance, New York Heart Association functional class, and echocardiography after ...
