Rupture of the aortic valve due to strain

Flail Aortic Valve and Acute Aortic Regurgitation Due to Spontaneous Localized Intimal Tear of Ascending Aorta

“…[3][4][5][6] Spontaneous laceration of the aorta may be caused by primary weakness of the aorta or excessive intraarterial pressure. [3][4][5][6] Spontaneous laceration of the aorta may be caused by primary weakness of the aorta or excessive intraarterial pressure.…”

“…[3][4][5][6] These abnormalities can be excluded con dently by TEE. Thus, it is considered to be especially useful in delineating the pathoanatomy of aortic regurgitation.…”

“…Laceration of the ascending aorta may occur spontaneously or as a result of blunt trauma. [3][4][5][6] Spontaneous laceration of the aorta may be caused by primary weakness of the aorta or excessive intraarterial pressure. Murray and Edwards reviewed 56 autopsied cases of spontaneous aortic laceration to relate the laceration to underlying causes and found that cystic medial necrosis of some degree was present in all patients but one.…”

“…Flail aortic valve can be caused by infective endocarditis, aortic dissection, and traumatic rupture of aortic cusps, but rarely by laceration of the ascending aorta. [3][4][5][6] These abnormalities can be excluded con dently by TEE. Therefore, in pa-tients with chest pain and acute aortic regurgitation associated with ail aortic valve, localized intimal tear of the aorta should be considered as a possible cause of ail aortic valve.…”

Long-Term Survival on Medical Therapy Alone after Blunt-Trauma Aortic Regurgitation: Report of a New Case with Summary of 95 Others

“…The time from the index incident to the diagnosis of traumatic AR ranged from immediately to 10 years or longer: 34 cases were diagnosed within 3 days, 2-34 20 within 1 month, 1,[35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] 12 within 3 months, 45,55-64 5 within 6 months, 1,65-68 4 within 1 year, 32,69-71 2 within 2 years, 72,73 2 within 3 years, 74,75 5 in over 5 years, 65,[76][77][78] and 12 after an unspecified duration. [79][80][81][82][83][84][85][86][87][88] Early diagnoses (within 3 d) were 35% of the total; in the other patients, AR apparently progressed slowly. Table III shows which cardiac structures were injured.…”
