Central retinal arterial occlusion is an ocular emergency. Central retinal artery occlusion following cardiac procedures have been described in adults. We describe a pediatric patient who developed central retinal artery occlusion following pulmonary artery stenting. It is important to highlight this potential risk to ensure early diagnosis and prompt treatment.

Behçet's Disease (BD) is a rare multi-systemic inflammatory disorder classified as a systemic vasculitis of unknown aetiology. Vascular involvement occurs in approximately 5-51.6% cases, affecting venous and arterial vessels. Cardiac involvement is rare in BD (6%). There have been published approximately 93 cases of BD associated with intracardiac thrombosis, with different treatments and courses. We present a case of a 35-year-old spanish male that, after a percutaneous pharmacomechanical thrombectomy with venous stent placement, developed high fever and extensive venous thrombosis despite anticoagulation including intracardiac thrombosis (ICT) in the right ventricle and pulmonary embolism that leaded to the diagnosis of BD...

The use of hybrid techniques to avoid neonatal cardiopulmonary bypass in high-risk individuals is well reported in the setting of hypoplastic left heart syndrome. We describe the use of that technique as a bridging procedure in high-risk neonates with an interrupted aortic arch. We report three cases where hybrid branch pulmonary artery banding and ductal stent implantation has been successfully used to defer complete repair, allowing recovery, maturity, and weight gain. This strategy may be considered for patients deemed at high risk for primary neonatal repair...

BACKGROUND: Vascular manifestations including pulmonary artery aneurysms and venous thrombosis are seen in up to 14% of patients with Behcet's disease. We report a patient who had recurrent deep vein thrombosis (DVT) as the presenting symptom of Behcet's Disease. METHODS: A 19-year-old male who presented with acute iliofemoral DVT, confirmed by intravascular ultrasound (IVUS) and venogram. May-Thurner syndrome was also observed. Repeated catheter-based pharmacomechanical thrombolysis, thrombectomy, and subsequent iliac vein stenting were performed...

BACKGROUND: Exposure to crystalline silica results in silicosis with initiation and progression of pulmonary fibrosis. The impaired lung parenchyma leads to pulmonary arterial hypertension and increased pressure in the right ventricle of the heart. Usually, the silicosis may be followed by enlargement of hilar lymphnodes, but silicosis-induced pulmonary artery stenosis with severe pulmonary hypertension is rare. Percutaneous pulmonary artery stenting and balloon angioplasty were performed to relieve stenosis and pulmonary hypertension...

Branch pulmonary artery stenosis is one of the most common complications late after the arterial switch operation. The pathophysiology of stenosis in these circumstances is very different to that encountered in with normally related great vessels. The LeCompte manoeuvre leaves the pulmonary arteries straddled and stretched over the aortic root which contributing significantly to the degree of stenosis encountered. Unilateral branch pulmonary artery stenosis rarely leads to significant symptoms in young patients with biventricular repairs; however, significant discrepancies in the split flows between right and left lung may place the patient in an unfavourable physiological position as they move in to middle age...

An elderly male patient with coronary heart disease underwent coronary angiography, which revealed bilateral severe coronary artery stenosis. Four stents were implanted, and at 5 h post-surgery, typical hemorrhagic shock appeared. Echocardiography verified heavy bleeding in the right thoracic cavity. Emergency angiography excluded injury or perforation of the coronary artery, aorta, right subclavian artery and brachiocephalic artery. Considering the patient's history of chronic obstructive pulmonary disease and severe cough during the operation, it was suspected that hemothorax was induced by a blood vessel rupture in the pleura...

This article reviews our experience using hybrid stage I palliation in the neonatal period and subsequently with comprehensive stage II palliation for hypoplastic left heart syndrome. Between June 1998 and April 2017, 154 patients with the diagnosis of hypoplastic left heart syndrome and variants underwent a hybrid stage I palliation (bilateral pulmonary artery banding and ductal stenting). One hundred thirty-nine patients could be further univentricularly palliated. One hundred twenty-one patients underwent a comprehensive stage II operation with an operative mortality of 6...

Nowadays, percutaneous pulmonary valve implantation (PPVI) is a suitable alternative to surgical procedure in patients with right ventricle outflow tract dysfunction. Two valves are currently available for PPVI: the Melody valve and the Edwards Sapien valve. The following complications may occur: coronary artery compression, deformation of the aortic root, stent or valve embolization, damage of distal pulmonary arteries, access site injuries. Here, we report on three cases of severe tricuspid regurgitation due to valvular and subvalvular apparatus damage during Edwards Sapien XT valve implantation...

OBJECTIVE: Endovascular stent-grafting provides an alternative treatment option for high-risk patients with ascending aortic disease. The feasibility of this approach has been demonstrated before. We assess the updated experience with ascending thoracic endovascular aortic repair and propose a modification of the landing zone classification based on the outcomes. METHODS: From 2006 to 2016, 39 patients deemed very high risk for open replacement underwent endovascular repair of ascending aorta for acute type A dissection (12, 31%), intramural hematoma (2, 5%), pseudoaneurysm (22, 56%), and chronic dissection suture line entry tear (3, 8%)...

BACKGROUND: Use of small diameter stents in young children and jailing of side branches pose significant challenges to future re-interventions. We sought to assess the capacity to induce longitudinal fractures in undersized stents to increase vessel diameter, and side cell fractures to enlarge stenotic jailed branches. METHODS: Retrospective review of patients who underwent attempted intentional stent fractures (ISF) from 01/06-02/17. RESULTS: Twenty-two patients, median age 4...

BACKGROUND: Our institutional approach to tetralogy of Fallot (TOF) with major aortopulmonary collaterals (MAPCAs) emphasizes unifocalization and augmentation of the reconstructed pulmonary arterial (PA) circulation and complete intracardiac repair in infancy, usually in a single procedure. This approach yields a high rate of complete repair with excellent survival and low right ventricular (RV) pressure. However, little is known about remodeling of the unifocalized and reconstructed pulmonary circulation or about reinterventions on the reconstructed PAs or the RV outflow tract conduit...

Left main coronary compression syndrome rarely occurs in patients with severe pulmonary hypertension. A 65-year-old woman with severe pulmonary hypertension due to an atrial septal defect suffered from angina on effort. Cardiac computed-tomography and coronary angiography revealed considerable stenosis of the left main coronary artery (LMA) caused by compression between the dilated main pulmonary artery trunk and the sinus of valsalva. Stenting of the LMA under intravascular ultrasound imaging was effective for the treatment of angina...
