Abstract  Middle aortic syndrome is a rare variation of aortic coarctation that is localized to the distal thoracic and abdominal aorta, and can involve the visceral and renal arteries. Irreversible organ damage and end-stage congestive heart failure may be the possible harmful complications of this disease in untreated patients. We ...

We aimed to evaluate the diagnostic performance of dual-source computed tomography coronary angiography (DSCT-CA) in the measurement of the ascending aorta (AA) diameter and compare the AA diameter in patients with severe bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV) stenosis. Eighty-eight consecutive patients (50 men, mean age 60.3 ± 13 year) ...

There is little information on relative survival with follow-up longer than 5 years in patients undergoing coronary artery bypass grafting (CABG) and patients undergoing percutaneous coronary intervention (PCI) with stenting. This study tested the hypothesis that CABG is associated with a lower risk of long-term (8-year) mortality than is stenting ...

The left internal thoracic artery (LITA) undergoes vascular remodelling when used for coronary artery bypass grafting. In this study we tested the hypothesis that the extent of the LITA remodelling late after coronary artery bypass grafting assessed by multidetector computed tomography is related to the severity of stenosis in the ...

Heavily calcified and severely stenotic distal arteries defined as unreconstructable, precludes the possibility of revascularization, resulting in major amputation in patients with critical limb ischemia. However, providing blood supply to the ischemic foot through the venous system instead of the arterial system may improve the circulation adequately for the healing ...

We report an uncommon case of positional occlusion of the vertebral artery associated with rheumatoid arthritis (RA). Plain radiography showed reducible atlantoaxial subluxation, and dynamic vertebral arteriography demonstrated positional occlusion of the left vertebral artery. The patient was treated with C1-2 posterior fusion and has since experienced no recurrent symptoms. ...

PURPOSE: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is progressively used in severe cardiogenic shock or in-hospital resuscitation to stabilize patients and to bridge to further therapeutic interventions. However, vascular access for coronary catheterization can be difficult under these conditions. It would thus be desirable to use arterial lines that are ...

Inhaled Nitric Oxide (iNO) has been shown to preferentially lower resistance in the pulmonary vasculature. The relative selectiveness of iNO in accomplishing this effect makes it an attractive drug to administer as salvage therapy in patients with acute right ventricular failure secondary to pulmonary embolism. We describe four cases in ...

The goal of this study was to compare the rate of cerebral microembolization during carotid artery stenting (CAS) with proximal versus distal cerebral protection in patients with high-risk, lipid-rich plaque. Cerebral protection with filters partially reduces the cerebral embolization rate during CAS. Proximal protection has been introduced to further decrease ...

BACKGROUND: Abdominal aortic aneurysm (AAA) is a degenerative disease of the abdominal aorta leading to progressive dilatation, intra-luminal thrombus (ILT) formation, and rupture. Understanding the natural history of AAA is essential, because different processes and, therefore, different biomarkers, could be involved at each stage of disease progression. The purpose of ...

Thoracic surgery patients should be regarded at high risk for postoperative venous thromboembolism (VTE). VTE mechanical and pharmacologic prophylaxis with low molecular weight heparin, or low-dose unfractionated heparin or fondaparinux (Arixtra) is therefore strongly recommended. Pharmacologic prophylaxis should be extended to 4 weeks after major cancer surgery. Pulmonary embolism should ...

Transcatheter closure of patent ductus arteriosus (PDA) with coils is accepted as an alternative to surgical ligation. We evaluated whether flow gradient across PDA, obtained by Doppler echocardiography, can aid in selecting coils for percutaneous ductal occlusion. 79 consecutive patients with PDA, who underwent successful percutaneous coil occlusion were retrospectively ...

Background: Scoring of mitral stenosis (MS) severity is very important for selection of patients for balloon mitral valvuloplasty (BMV). Objective: We propose a novel yet simple, independent parameter of MS severity based on the posterior mitral valve leaflet to anterior mitral valve leaflet length ratio (PMVL/AMVL length ratio). It could ...

Cardiothoracic surgeons commonly use the internal thoracic artery (ITA) and the right gastroepiploic artery (RGEA) when performing a coronary artery bypass graft (CABG). Although the development of CABG surgery has enabled long-term survival in patients with coronary artery disease, malignant diseases are more common in older patients. We present the ...

Fractional flow reserve (FFR), an invasive pressure-derived index of stenosis severity, can be performed easily, rapidly, and safely in patients with coronary artery disease as a surrogate of non-invasive detection of ischemia. Over the last decades, profound clinical and scientific evaluation has demonstrated that FFR is one of the few ...

There is no sensitive tool to monitor embolic events and predict patients at a risk for strokes during thoracic endovascular aortic repair. We examined the relationship between the number of high intensity transient signals (HITS) by transcranial doppler ultrasound and the extent of atherosclerotic plaques in aortic arch. Thirteen patients ...

OBJECTIVES: Short relative telomere length (RTL) is associated with vascular ageing, inflammation and cardiovascular risk factors. Previous studies have reported an association between abdominal aortic aneurysm and short RTL. The presence of atherosclerosis among patients with aneurysm disease may, however, be a confounder. The aim was to explore the associations ...

Left main coronary artery disease, present in 5-9% of patients with angina pectoris, is associated with high mortality risk when treated medically. For several decades coronary artery bypass grafting (CABG) has been regarded as the treatment choice for unprotected left main coronary artery (ULMCA) disease patients. However, proximal location and ...

We report transventricular mitral valve operations in 2 patients with severe mitral regurgitation and postinfarction left ventricular rupture and pseudoaneurysm. The first patient had direct papillary muscle involvement necessitating replacement of the mitral valve. The second patient had indirect mitral involvement allowing for placement of an atrial mitral annuloplasty ring ...

Before yttrium-90 ((90)Y) radioembolization administration, the authors consolidated arterial inflow by embolizing variant hepatic arteries (HAs) to make microsphere delivery simpler and safer. The present study reviews the technical and clinical success of these consolidation procedures. Preparatory and treatment angiograms were retrospectively analyzed for 201 patients. Variant HAs were coil-embolized ...

The incidence rate of aneurysmal subarachnoid hemorrhage (SAH) in the elderly is increasing. Although endovascular coiling has become a major form of treatment for SAH in elderly patients, not all ruptured aneurysms can be managed with an endovascular approach. Conventional surgical clipping still plays an important role in SAH treatment. ...
