The patient was admitted for the evaluation of resistant grade III high blood pressure. The physical examination revealed a blood pressure gradient between the upper and lower limbs, absent femoral pulses, a diffuse continuous murmur over the chest, and hyperpulsatility of the carotid arteries and sternal notch. A transthoracic echocardiography outlined a narrowing in the caliber of the isthmic aorta without acceleration of flow or gradient. Thoracic CT angiography revealed a complete aortic coarctation with interruption of continuity between segment 3 and the descending aorta.展开更多

Arterial hypertension is a frequent circumstance of discovery. We reported the case of a 22-year-old Guinean man who had been followed for 5 years for hypertension. Clinically, he presented with hypertension of the upper limbs with a systolic pressure gradient of 100 mmHg. The diagnosis was confirmed by thoracic angioscan, which showed a 65.8% coarctation of the abdominal aorta. He was on triple antihypertensive therapy combining Atenolol 100 mg, Amlodipine 10 mg and Perindopril 10 mg. He is awaiting interventional treatment. His blood pressure is stable at around 140/90 mmHg.展开更多

These lesions can be treated either simultaneously or sequentially. Herein, we present the first successful report of simultaneous balloon angioplasty and Amplatzer duct occluder device implantation in a single-sitting in an 8-year-old boy with severe aortic coarctation and patent ductus arteriosus. The coarctation gradient decreased from 70 mmHg to 10 mmHg and a complete closure of the ductus arteriosus was achieved without any complication. Fellow interventional cardiologists may consider single-stage transcatheter treatment in young children with combination of these two lesions.展开更多

Computed tomography angiography (CTA) showed a short segment aortic narrowing with diameter of 9.2 mm a small intimal tear, a true lumen, a false lumen, a markedly thick mural thrombus and pleural effusion. Open surgical procedure was performed and the aortic coarctation (CoA) and aortic dissection were resected and a 24-mm prosthetic graft was anastomosed. No pseudo aneurysms were present at the anastomosis sites on the follow up CTA.展开更多

He underwent simultaneously in singlestage a Bentall’s procedure and an extra-anatomic ascending-descending aortic bypass grafting by 14-mm Dacron tube, through median sternotomy. The immediate postoperative outcome was favourable. The CT scan control for 7 years after surgery showed a good patency of the extra-anatomic bypass.展开更多

Then, we compared these results with those obtained for a proposed model without and with aortic coarctation, while introducing a real tridimensional magnetic resonance imaging geometry in the simulation process. The conclusion is that our proposed model reproduces, with a high agreement, the real case obtained from imaging data.展开更多

The pressures proximal and distal to stenosis were 185/110 and 95/70 mmHg, and the pressure gradient across the stenosis was 90/40 mmHg. After the operation of thoraco-abdominal bypass graft, the pressure difference between the upper and lower extremities eventually disappeared.展开更多
