CardioPulse: developments in the treatment of aortic aneurysms in 2014

2015

Since the introduction of EndoVascular Aortic Repair (EVAR) for the treatment of abdominal aortic aneurysms (AAA) more than 20 years ago, the technique has evolved rapidly, from tubular grafts for fairly simple abdominal aortic anatomy, to bifurcated, fenestrated, branched, or parallel grafts for complex aortic aneurysms, no longer confined to the infrarenal abdominal aorta.

RUPTURE OF AN AORTIC DISSECTION INTO THE RIGHT ATRIUM IN A PATIENT WITH PREVIOUS AORTIC VALVE REPLACEMENT: A CASE REPORT

2005

We report the case of a 73-year-old man with a history of previous aortic valve replacement in 1990 and rupture of an aortic dissection into the right atrium. The patient was admitted to the emergency room because of chest pain, stopped not long after. The electrocardiogram did not show any signs of ischemia and myocardial enzymes were not increased. Transthoracic echocardiography revealed aortic root dilation (maximum diameter 60 mm) extended to the aortic arch, and the presence of a flow from the ascending aorta to the right atrium (evocative of a fistula between the two chambers). The aortic valvular prosthesis function was good. Transesophageal echocardiography confirmed an aorta-right …

Thoracic Endovascular Aortic Repair (TEVAR) for the treatment of aortic diseases: a position statement from the European Association for Cardio-Thora…

2012

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment modality, which has been rapidly embraced by clinicians treating thoracic aortic disease.1–4 Fundamentally, it is a far less invasive approach than open surgery and its availability and relative ease of application has changed and extended management options in thoracic aortic disease, including in those patients deemed unfit or unsuitable for open surgery. In the operating room, this requires considerable perceptual, cognitive and psychomotor demands on the operators. The dramatic expansion of TEVAR activity has necessarily prompted a requirement to systematically consider the indications, appropriateness, limitations and…

Acute aortic dissection type A

2012

Abstract Background Acute aortic dissection type A (AADA) is a life-threatening vascular emergency. Clinical presentation ranges from pain related to the acute event, collapse due to aortic rupture or pericardial tamponade, or manifestations of organ or limb ischaemia. The purpose of this review was to clarify important clinical issues of AADA management, with a focus on diagnostic and therapeutic challenges. Methods Based on a MEDLINE search the latest literature on this topic was reviewed. Results from the German Registry for Acute Aortic Dissection Type A (GERAADA) are also described. Results Currently, the perioperative mortality rate of AADA is below 20 per cent, the rate of definitive…

DISSECTION PROPERTIES OF ANEURYSMAL AND NONANEURYSMAL HUMAN ASCENDING THORACIC AORTA: PRELIMINARY RESULTS

2010

Ascending thoracic aortic aneurysm (ATAA) is among the most devastating forms of cardiovascular disease, causing a significant mortality despite current medical and surgical treatments [1]. Moreover these therapies themselves are associated with great risk of mortality or morbidity, complicated by the advanced age of the typical patient, and high surgical costs. The mechanics of spontaneous aortic dissection is not fully understood. It is generally believed that aortic dissection initiates as an intimal tear in which a separation of wall layers produces the formation of a ‘false’ lumen. The dissection may propagate axially and/or circumferentially due to blood flow and pressure. Dissection …

Association of Fiber Orientation and Dissection Properties of Ascending Thoracic Aortic Aneurysms With Aortic Valve Morphology

2011

Type A aortic dissection (AoD) of an ascending thoracic aortic aneurysm (ATAA) is a life-threatening cardiovascular emergency with a high potential for death. Despite improved surgical techniques, the morbidity risk for emergent surgery remains 24% worldwide according to data from the International Registry of Acute Aortic Dissection [1].Copyright © 2011 by ASME

Biomechanics and Pathobiology of Aortic Aneurysms

2011

Biomechanical weakening of the aorta leads to aneurysm formation and/or dissection and total biomechanical failure results in rupture, which is often fatal. The most common aneurysm is the abdominal aortic aneurysm (AAA) whereas thoracic aortic aneurysms (TAA) involve the ascending or descending segments of the aorta. Biomechanical strength of the aorta is maintained in part via balance between the integrity of the aortic medial and adventitial extracellular matrix and the health of the mural cells. From a biomechanical perspective, aneurysms rupture or dissect when wall stresses locally exceed the wall strength. Pathobiologic mechanisms, pre-disposing disorders and variability of patient d…
