Heparin-induced thrombocytopenia (HIT) is a potentially life-threatening, adverse effect of heparin therapy. Patients with this complication require an alternative approach to anticoagulation. Bivalirudin is a direct thrombin inhibitor with an efficacy comparable to that of heparin, a short half-life, and reduced bleeding complications in adults. We present the case of ...

With the advent of newer optional/retrievable inferior vena caval filters, there has been a rise in the number of filters inserted globally. This review article examines the currently available approved optional filter models, outlines the clinical indications for filter insertion and examines the expanding indications. Additionally, the available evidence behind ...

The absence of the inferior vena cava is a rare congenital anomaly and represents a modest risk for deep-venous thrombosis. When associated with genetic polymorphism or other hypercoagulable states, the risk can increase several times. A case of young man with the inferior vena cava agenesia and deep-venous thrombosis of ...

Aberrant placement of vena cava filters has been documented. Only one case of intraaortic deployment, in which the filter was left at the aortic bifurcation with no adverse effects over a 4-year follow-up period, has been reported. We describe the endovascular retrieval of an intraaortic Greenfield filter using a snare ...

Deep venous thrombosis and pulmonary embolism constitute common preventable causes of morbidity and mortality. The incidence of venous thromboembolism (VTE) continues to increase. Standard anticoagulation therapy may reduce the risk of fatal PE by 75% and that of recurrent VTE by over 90%. For patients who are not candidates for ...

We present the surgical resection and repair, using port-access, in a case of extensive lipomatous hypertrophy of the interatrial septum (IAS). There was tumourous lipomatous hypertrophy on the superior vena cava (SVC) - atrial junction close to the aortic root beside massive IAS hypertrophy. Resection of involved IAS and SVC ...

Protein-losing enteropathy has been associated with the Fontan operation, restrictive cardiomyopathy, constrictive pericarditis, tricuspid valvar stenosis and insufficiency, and superior caval venous obstruction. The mechanism of development of this complication of cardiac disease likely is multifactorial. We report here our experience with 3 patients with protein-losing enteropathy. Two had superior ...

Double inferior vena cava is a rare congenital anomaly. Recognition of such venous anomalies is important in the evaluation and surgical treatment of retroperitoneal disease. Newer radiological modalities such as three-dimensional reconstruction of spiral computed tomography help to define such anomalies and avoid significant morbidity during surgical exploration. We present ...

Catheter ablation of the slow pathway for atrioventricular nodal re-entrant tachycardia (AVNRT) is not always possible due to congenital or acquired obstruction of the inferior vena cava (IVC). Although a superior access has been proposed as an alternative approach, a poor manoeuvrability and a lower stability of the ablation catheter ...

Persistent left superior vena cava (SVC) is an uncommon condition, usually encountered during cannulation of the left subclavian vein. We describe a patient who required a cardiac device upgrade to cardiac resynchronization implantable cardioverter defibrillator for biventricular failure. The presence of a persistent left SVC proved to be a blessing ...

We report the case of a 56-year-old woman affected by recurrent paroxysmal atrial fibrillation and sick sinus syndrome. Before pacemaker implantation, a diagnosis of left superior vena cava persistency was made. After some years, at pacemaker replacement, an inferior vena cava anomaly was suspected because of the difficult progression of ...

BACKGROUND: There exists large geometric variability among total cavopulmonary connections (TCPC) because of the patient-specific anatomies and the chosen surgical procedure. In this study we present quantitative comparison of the geometric characteristics of the extracardiac and intraatrial Fontan anatomies, the two commonly used TCPC procedures. METHODS: A method of centerline ...

Most abdominal aortic aneurysms are asymptomatic, but 1% to 4% of cases present with a life-threatening complication. A spontaneous right common iliac artery-inferior vena cava fistula, a rare condition caused by infrarenal aortoiliac aneurysm, is reported. In this case, the condition was successfully managed with primary endovascular stent-graft treatment.

We attempted to investigate whether computed tomography pulmonary angiography (CTPA) in the expiratory phase can improve contrast enhancement of the pulmonary arteries and mitigate the effect of inspiratory transient attenuation artifact, potentially salvaging nondiagnostic studies. Eighteen patients with indeterminate inspiratory CTPA, despite proper contrast bolus were studied. Patients were rescanned ...

Spontaneous aorto-caval fistula is a rare complication of abdominal aortic aneurysm. A definitive diagnosis is sometimes difficult, as the classic diagnostic signs (pulsatile abdominal mass with bruit, high-output hearth failure, and acute dyspnea) are present in about half of the patients. Diagnosis may be suspected from clinical symptoms, but sometimes ...

We report a case of atrioventricular (AV) reentrant tachycardia with ostial atresia of the coronary sinus (CS). On levophase coronary venogram, dual anomalous venous drainage into both atria was seen; no ostium of the CS and no persistent left superior vena cava were noted. Based on mapping, radiofrequency (RF) energy ...

Aneurysms of the coronary arteries are rare events. In most cases, such abnormalities are clinically silent and, when they cause symptoms, there are dyspnea and/or angina. Our report describes a case presenting with dyspnea; the admission electrocardiogram demonstrated largely spread ischemia in the lower-lateral leads and myocardial necrosis in the ...
