| | Aortic Dissection and You |
 | | Coarctation of the aorta most often needs to be surgically corrected. | | | The classic presentation of an aortic dissection is the development of a sudden, severe, tearing, ripping chest pain (symptom you describe), accompanied by a changing heart murmur (sign the physician can detect). | | | One woman was 36 when she died of an aortic aneurysm after surgical repair of aortic stenosis. |

| | Bicuspid aortic valve is observed in 85% of patients. | | | Rebound and paradoxical hypertension is observed frequently and may be related to the baroreceptor-mediated increase in sympathetic activity and reflex vasospasm in the vascular territory distal to the coarctation. | | | If the patient has associated bicuspid aortic valve, an aortic ejection sound, a short midsystolic murmur, and/or early diastolic murmur of aortic regurgitation may be audible. |

| | The concept tended to lose credibility when Edwards and his colleagues, in a histological study of coarctations from ‘adult’ cases, showed them to be formed of fibrous rather than recognizably ductal tissue. | | | Important malformations occur within the heart in association with coarctation or interruption of the arch. | | | Instead, they promoted a concept based on inequality of flow through the aortic and pulmonary pathways during fetal life. |

| | This technique is similar to the classic end-to-end repair of coarctation of the aorta discussed above, but differs in that the aortic arch is incised more proximally along its lesser curvature, and the lower aorta is incised further along its posterior-lateral aspect. | | | The advantage of this variation is that relief of aortic arch hypoplasia is possible since the aortic arch is more widely opened, and therefore, obstruction is more readily relieved. | | | Associated aortic arch hypoplasia is not addressed with this technique. |

| | It was felt that aortic valve replacement (AVR) and surgical coarctation repair would be high risk given his left ventricular function. | | | In general, balloon angioplasty has been proven to be safe but with some potential complications: 5%-25% incidence of recoarctation (especially in infants), paracoarctation aortic dissection or rupture and a 5%-7% incidence of aneurysm formation. | | | 7 However, given the high success rate and the much less invasive nature, angioplasty has become an attractive alternative to surgery in the treatment of adult aortic coarctation. |

| | However, recent in-vitro experiments suggest the presence of this spectral Doppler pattern is as much related to the severity of coarctation as it has to do with changes in aortic compliance. | | | Using state of the art multidisciplinary numerical analysis tools, the purpose of this study was to investigate the specific fluid and wall mechanics present in coarctation of the aorta to further understand these relationships. | | | Insights into the Effect of Aortic Compliance on Doppler Diastolic Flow Patterns Seen in Coarctation of the Aorta: A Numerical Study |

| | Aortic coarctation may return even after successful surgery or balloon dilation. | | | Coarctation of the aorta usually doesn't have symptoms. | | | Recurrent coarctation is usually treated with nonsurgical balloon dilation or by implanting a stent using cardiac catheterization. |

| | BACKGROUND: We compared the outcome of lifelong treatment with the ACE inhibitor ramipril in young prehypertensive stroke-prone spontaneously hypertensive rats (SHR-SP) and age-matched normotensive Wistar-Kyoto (WKY) rats. | | | On the other hand, chronic ACE inhibition prevented the development of hypertension and LVH in both 129/SvEvTac and B2-KO mice given DOCA-salt or subjected to aortic coarctation, suggesting that kinins do not participate in the chronic antihypertensive and antihypertrophic effects of ACEi in these 2 models of hypertension. | | | However, it is controversial as to whether kinins oppose the hypertensinogenic effect of deoxycorticosterone acetate plus salt (DOCA-salt) or aortic coarctation and whether they mediate both chronic antihypertensive and cardiac antihypertrophic effects of ACEi in hypertension. |

| | The lack of afferent feedback from the kidneys for AVP release from the central nervous system in rats with previous renal denervation allowed ANG II to play the major role in the onset of the hypertensive response. | | | Angiotensin II (ANG II) and vasopressin (AVP) act together with the mechanical effect of aortic constriction in the onset of acute aortic coarctation hypertension. | | | As expected, a role for catecholamines was ruled out in this model of hypertension, presumably due to the inhibitory effect of the sinoaortic baroreceptors. |

| | Coarctation of the Aorta |
| | It is unusual for a patient to remain asymptomatic and not be diagnosed with coarctation of the aorta (COA) until age 51, as in this patient. | | | Coarctation of the aorta is the most likely diagnosis. | | | The short length of aortic narrowing, combined with the the patient's age and symptoms, suggests the localized or postductal type. |

| | Coarctation |
| | Coarctation of the aorta is a constricted segment of the aorta that obstructs blood flow to the body. | | | This procedure is done in the cardiac catheterization lab. | | | Coarctations typically occur as isolated defects, but may occur with a ventricular septal defect, subaortic stenosis, or complex congenital heart defects. |
