Angiography in a 30-year-old man revealed the unique combination of aortic coarctation and an unusual arch anomaly. Proximal to the coarctation, a single arch vessel trifurcated into the brachiocephalic, left common carotid and left subclavian arteries. This anomalous arch vessel is a normal equine variant.
The echocardiographic appearances in a case of coarctation of the aorta, first suspected at 21 weeks of intrauterine life, changed progressively during this time. Early right ventricular hypertrophy and increasing aortic arch hypoplasia were evident and suggest the possible sequence of evolution of the coarctation in this case.
We report an unusual case of pseudoaneurysm and coarctation of the descending thoracic aorta after trauma. The coarctation of aorta resulted in hypertension, severe left ventricular dysfunction, and symptoms of congestive heart failure. Surgical bypass resulted in control of blood pressure and improvement of heart failure symptoms. The mechanism of aortic injury leading to the development of th...
We are reporting a rare case of a patient with the right coronary artery giving a large collateral vessel to an intercostal artery in a patient with repaired coarctation of aorta. A 64 year-old man with coarctation of the aorta, surgically repaired at 18 years of age, presented with dyspnea. A trans-esophageal echocardiogram revealed a severely stenotic bicuspid aortic valve.
Patient Selection Several surgical approaches have been described for the management of adult patients with acquired heart disease and paraductal coarctation of the aorta. A staged procedure using both median sternotomy and left thoracotomy, a catheter-based intervention of the coarctation combined with sternotomy, and single-stage simultaneous correction of both lesions via sternotomy are some...
OBJECTIVE Hemodynamic stress participates in the initiation and progression of aneurysmal degeneration. Coarctation increases flow-mediated stress on the aortic wall. We tested the hypothesis that prolonged coarctation of an infrarenal abdominal aorta (AA) segment leads to abdominal aortic aneurysm (AAA) formation in mini pigs. METHODS An asymmetric, funnel-shaped flow path was created by con...
OBJECTIVE The aim of this study is to describe our experience in aortic coarctation surgery in adult patients by assessing the immediate and mid-term outcomes. METHODS From January 1987 to March 2000, 50 consecutive adult patients underwent surgery for correction of aortic coarctation, through left lateral thoracotomy. Of these, forty two (84%) patients presented high blood pressure, with mea...
Background: Aortic coarctation poses a lifelong high cardiovascular risk, despite successful surgical or percutaneous management. Objective: To investigate whether an abnormal aortic function is involved in the higher cardiovascular risk in patients after correction of aortic coarctation. Methods: We recorded aortic pressure waveforms and elastic properties by MRI in 13 patients with normal blo...
BACKGROUND We report a multi-institutional experience with intravascular stenting (IS) for treatment of coarctation of the aorta. METHODS AND RESULTS Data was collected retrospectively by review of medical records from 17 institutions. The data was broken down to prior to 2002 and after 2002 for further analysis. A total of 565 procedures were performed with a median age of 15 years (mean=18....
