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 ...

The Eustachian valve (EV) is an embryological remnant of the inferior vena cava valve that prenatally directs the oxygenated blood from inferior vena cava across the patent foramen ovale (PFO) into systemic circulation. We present a 30-year-old man with PFO whose prominent EV initiated spontaneous right-to-left shunt without Valsalva maneuver ...

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 ...

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 ...

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 ...

Pulmonary arterial hypertension (PAH) is a rare but serious condition, which if untreated, is associated with a 2-3-year median survival time. A number of treatment options are available for PAH, leading to improvements in exercise capacity, symptoms, and hemodynamics. However, the disease remains incurable and most patients will ultimately progress ...
