Survival to advanced age is exceptional in patients with unrepaired aortic coarctation. We report the case of an 81-year-old man with aortic coarctation and total occlusion who was otherwise asymptomatic. Coarctation was suspected when a femoral-radial pulse delay was noted during his routine physical examination. A 70-mmHg systolic blood pressure gradient between the upper and lower extremitie...

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. An infrarenal AA segment of Taiwanese Lanyu mini pigs was wrapped with an 8 m...

Abdominal aortic coarctation is an extremely rare vascular pathology. Its etiology can be congenital or acquired. Here we present a case of acquired infrarenal abdominal coarctation in a 66-year-old woman who complained of low back and legs pain. She had no signs of resting lower limb ischemia, with diminished distal pulses and normal blood pressure in upper and lower extremities. Magnetic reso...

Aortic coarctation is a congenital vascular lesion, usually diagnosed and corrected in childhood or early adulthood. Most of the untreated patients with aortic die before age 50 years. Coarctation cardiac lesions complex clinical situation that necessitates surgical treatment different pathologies strategies.

Coarctation of the aorta is one of the five main congenital cardiovascular failures, accounting for 6–8 percent of these failures. This research aimed to simulate the blood flow of a seventeen-year-old male teen with a mild coarctation at one-third of his aorta's descending branch. The simulation was performed by extracting the domain and the input pulsatile velocity signal as the boundary cond...

Introduction Several reports on anomalies of the aortic arch concomitant with coaretation of the aorta are to be found in the literature.3 This paper describes such anomalies as they were found in two of our surgical cases, which showed unusual features not hitherto described in the literature available to us. These anomalies, although rare, are of practical importance with a view to differenti...

single-stage or a two-stage procedure using hybrid techniques. Aortic valve replacement 2 weeks after stent implantation to the coarctation has been reported [21]. This technique necessitates an additional general anaesthetic procedure and lengthens the hospital stay. We performed a hybrid technique in three patients with coarctation and accompanying cardiac lesions. After stent deployment, we ...

BACKGROUND In neonates, it is challenging to diagnose aortic coarctation in the setting of a patent ductus arteriosus (PDA). Frequently, serial echocardiograms are performed, and diagnosis is delayed until the PDA closes. The purpose of this study was to identify echocardiographic predictors of neonatal coarctation in the presence of a PDA in cases in which diagnosis is uncertain. METHODS We ...

OBJECTIVES The study sought to determine the outcome of pregnancy in women with coarctation of the thoracic aorta. BACKGROUND Patients with coarctation of the thoracic aorta are expected to reach childbearing age, but data on the outcome of pregnancy in this population are limited. METHODS The Mayo Clinic database was reviewed for women of childbearing age (> or =16 years old) with a diagno...
