1/158. Repair of a pseudoaneurysm of the ascending aorta after aortic valve replacement.An elderly woman underwent an aortic valve replacement and 5 months later developed a pseudoaneurysm from the anterior aspect of the proximal ascending aorta (AA). The pseudoaneurysm was approached through a redo-median sternotomy, on cardiopulmonary bypass (CPB), mild hypothermia, and a beating heart, with a temporary fingertip occlusion of its ostium, and repaired successfully using mattress monofilament sutures enforced by pledgets. The standard approach to such pseudoaneurysms is a CPB and hypothermic circulatory arrest (HCA) prior to mid-sternotomy, and replacement of the AA. But, when a pseudoaneurysm arises from a narrow ostium on the anterior aspect of the AA, as in this case, it can be sutured closed with pledgets under CPB with a mild hypothermia and a beating heart.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
2/158. Potential utility of left heart contrast agents in diagnosis of myocardial rupture by 2-dimensional echocardiography.This case illustrates the use of intravenous injections of a contrast agent during 2-dimensional echocardiography in a patient with myocardial rupture after myocardial infarction. Intravenous injections of echocardiographic contrast agents may have potential use in the identification of intrapericardial hemorrhage after myocardial infarction caused by myocardial rupture or development of ventricular pseudoaneurysm.- - - - - - - - - - ranking = 2keywords = heart (Clic here for more details about this article) |
3/158. Ultrasonographic evaluation of tumorous lesions in digital vessels.ultrasonography has recently been used for evaluation of various conditions in Orthopaedics. Ultrasonographic examination is a noninvasive screening test especially for soft tissue masses. ultrasonography is also a useful and essential diagnostic tool in cardiovascular disorders because real-time images of heart and vessels can be obtained. However, there have been few reports which describe ultrasonographic evaluation of tumorous lesions in digital vessels. In this paper, such lesions in two cases were evaluated by ultrasonography. An aneurysm of the digital artery is one of the definite candidates for ultrasonographic evaluation.- - - - - - - - - - ranking = 0.5keywords = heart (Clic here for more details about this article) |
4/158. Repair of an ascending aorta pseudoaneurysm by way of superior ministernotomy.A wide ascending aorta pseudoaneurysm occurring 10 years after uncomplicated aortic valve replacement was successfully repaired using a superior ministernotomy and femoral-femoral cannulation. In this setting, a limited sternal incision minimized the risk of pseudoaneurysm rupture during dissection and allowed safe isolation of the target cardiac structures.- - - - - - - - - - ranking = 1.6136345837575keywords = cardiac (Clic here for more details about this article) |
5/158. Pseudoaneurysm of the left ventricular free wall caused by tumor infiltration.Ventricular pseudoaneurysms occur as complications of myocardial infarction, heart surgery, trauma, and infective endocarditis. The process involves rupture of the ventricular wall where a structural weakness exists and containment of the blood by the pericardium. Although various malignancies may invade the heart, a pseudoaneurysm of the left ventricle caused by tumor has not been reported.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
6/158. The spectrum of aortic complications after heart transplantation.BACKGROUND: The connection between the donor and the recipient aorta is a potential source of early and late complications as a result of infection, compliance mismatch, and technical and hemodynamic factors. Moreover, the abrupt change in systolic pressure after heart transplantation involves the entire thoracic aorta in the risk of aneurysm formation. The aim of this study was to analyze the types of aortic complications encountered in our heart transplantation series and to discuss etiology, diagnostic approach, and modes of treatment. methods: Of the 442 patients having orthotopic heart transplantation and the 11 patients having heterotopic heart transplantation at our center, 9 (2%) sustained complications involving the thoracic aorta. These 9 patients were divided into four groups according to the aortic disease: acute aortic rupture (2 patients); infective pseudoaneurysm (3 patients); true aneurysm and dissection of native aorta (2 patients); and aortic dissection after heterotopic heart transplantation (2 patients). Surgical intervention was undertaken in 8. RESULTS: Five (83%) of 6 patients who underwent surgical treatment for noninfective complications survived the operation, and 4 are long-term survivors. One patient who underwent a Bentall procedure 71/2 years after heterotopic heart transplantation died in the perioperative period of low-output syndrome secondary to underestimated chronic rejection of the graft. One patient with pseudoaneurysm survives without surgical treatment but died several years later of cardiac arrest due to chronic rejection. Both patients operated on for evolving infective pseudoaneurysm died in the perioperative period. CONCLUSIONS: Infective pseudoaneurysms of the aortic anastomosis are associated with a significant mortality. In noninfective complications, an aggressive surgical approach offers good long-term results. The possibility of retransplantation in spite of complex surgical repair should be considered in the late follow-up after heart transplantation, due to the increasing incidence of chronic rejection.- - - - - - - - - - ranking = 7.1136345837575keywords = cardiac, heart (Clic here for more details about this article) |
7/158. Repeat syncopal attacks due to postsurgical right ventricular pseudoaneurysm.Pseudoaneurysm of the right ventricular outflow tract is a rare lesion caused by disruption of the ventricular wall that allows the blood to leak into the surrounding space. It often complicates surgery involving right ventriculotomy and progressively increases in size, therefore causing airway compression, pulmonary perfusion asymmetry, thromboembolism, and rupture. We report on a patient who developed right ventricular pseudoaneurysm early after surgery for atrio-ventricular septal defect with tetralogy of fallot and needed emergency surgical repair due to low cardiac output and repeat syncopal attacks.- - - - - - - - - - ranking = 1.6136345837575keywords = cardiac (Clic here for more details about this article) |
8/158. Non-mycotic pseudoaneurysm in the ascending aorta following cardiac surgery.Cannulation of the ascending aorta is the recognized method to achieve arterial return during cardiopulmonary bypass. Mediastinal infection after cardiac surgery can cause disruption at the point of insertion, and give rise to a pseudoaneurysm in the ascending aorta. Although rare, a pseudoaneurysm can occur without clear evidence of infection. Here we report two cases that received aortic valve replacement and that developed ascending aortic aneurysms after surgery. Based on our clinical findings, these aneurysms were related to the arterial cannulation into the aorta and not to any infection.- - - - - - - - - - ranking = 146.84851348101keywords = cardiac surgery, cardiac (Clic here for more details about this article) |
9/158. Identification of cardiac masses and abnormal blood flow patterns with harmonic power Doppler contrast echocardiography.Power Doppler is an ultrasound technique that color-encodes the change in amplitude of the ultrasound signal, which reflects changes in the position of scatterers between ultrasound pulses. Power Doppler can be used with echocardiographic contrast agents in a harmonic imaging mode to opacify a cardiac chamber. The opacification of a cardiac chamber can aid in visualizing the silhouette of intracardiac masses and displaying blood flow patterns. Four cases are presented that demonstrate the use of harmonic power Doppler to aid in the identification of a left ventricular apical thrombus, a left atrial thrombus, and a left ventricular pseudoaneurysm.- - - - - - - - - - ranking = 11.295442086303keywords = cardiac (Clic here for more details about this article) |
