Trancatheter heart valve (THV) thrombosis is effectively treated with anticoagulation but alternative therapies are required when a faster gradient reduction is needed. Open heart surgery has been rarely performed due to the high perioperative mortality and only five cases have been described so far. Here we describe a case of emergent surgical explantation for THV thrombosis after a valve-in-valve. A 67years old man underwent transcatheter aortic valve implantation for a failed surgical bioprosthesis Epic 21mm (St...

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...

A 48-year-old woman suffering from Takayasu arteritis presented with middle aortic syndrome consisting of abdominal pain, refractory hypertension with pulmonary edema and pleural effusions, and lower limb ischemia. She failed to improve with high-dose steroid therapy and underwent endovascular stenting of two severe stenoses in the supraceliac and infrarenal aorta. Her symptoms resolved and hypertension improved after the procedure.

Iliac venous aneurysms are rare vascular abnormalities that may be manifested by abdominal masses, pelvic tenderness, or hypovolemia and may lead to rupture, thrombosis, pulmonary embolism, paradoxical embolism, or death. Inferior vena cava agenesis, like venous aneurysm, is an uncommon condition that may present with deep venous thrombosis. This report describes a patient with inferior vena cava agenesis and iliac venous aneurysm rupture treated with emergent iliocaval reconstruction and endovascular stent graft placement...

Catheter ablation for symptomatic and drug-resistant atrial fibrillation is considered as the main acquired cause of pulmonary vein stenosis in adults. Controversy currently exists about the optimal treatment approach of this entity. Stenting seems to achieve lower vessel restenosis rates than isolated balloon angioplasty. However, these techniques are not exempt from complications. We present a case of spontaneous massive haemothorax presenting as a late complication of stent implantation in a patient with pulmonary vein stenosis...

OBJECTIVES: To evaluate the procedural success and outcome of inter-atrial stenting. BACKGROUND: Inter-atrial stenting has been shown to be an effective way to maintain inter-atrial blood flow, however it is considered a high risk procedure, usually performed urgently in patients with significant hemodynamic compromise. METHODS: Between September 2004 and August 2016, inter-atrial stenting was attempted in 29 children. Procedural, clinical, and follow-up data were collected retrospectively...

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...

Abdominal aortic aneurysm (AAA) is most commonly defined as a maximal diameter of the abdominal aorta in excess of 3 cm in either anterior-posterior or transverse planes or, alternatively, as a focal dilation ≥ 1.5 times the diameter of the normal adjacent arterial segment. Risk factors for the development of AAA include age > 60, tobacco use, male gender, Caucasian race, and family history of AAA. Aneurysm growth and rupture risk appear to be associated with persistent tobacco use, female gender, and chronic pulmonary disease...

Patient-specific computational models have been extensively developed over the last decades and applied to investigate a wide range of cardiovascular problems. However, translation of these technologies into clinical applications, such as planning of medical procedures, has been limited to a few single case reports. Hence, the use of patient-specific models is still far from becoming a standard of care in clinical practice. The aim of this study is to describe our experience with a modelling framework that allows patient-specific simulations to be used for prediction of clinical outcomes...

BACKGROUND: In single ventricle patients, aorticopulmonary collaterals (APCs) and pulmonary arteriovenous malformations (PAVMs) following superior cavopulmonary shunt (CPS) can complicate orthotopic heart transplant (OHT) by cyanosis and hemoptysis. Though PAVMs can regress with restoration of hepatic venous flow to the pulmonary circulation, the effects of hypoxemia on the "unconditioned" allograft are not known. CASES: Two patients with significant PAVMs after CPS were cyanotic following OHT...

BACKGROUND: The incidence of pulmonary vein stenosis (PVS) as complication after pulmonary vein isolation (PVI) for atrial fibrillation (AF) has decreased in the last decade. However, as PVI for AF is becoming more prevalent, the incidence remains considerable in absolute terms. The purpose of this meta-analysis is to investigate the optimal approach for management of PVS after PVI for AF. METHODS AND RESULTS: We searched electronic scientific databases for studies comparing plain balloon angioplasty (BA) versus stenting for PVS after PVI for AF...

BACKGROUND: Guidelines allow percutaneous pulmonary valve implantation (PPVI) in conduits above 16mm diameter. Balloon dilatation of a conduit to a diameter>110% of the original implant size is also not recommended. We analyzed patients undergoing PPVI in such conditions. METHODS AND RESULTS: Nine patients (May 2008-July 2016) from 8 institutions underwent PPVI in conduits <16mm diameter. Five patients with 16-18mm conduit diameter underwent PPVI after over-expansion of the conduit>110%...
