Ascending aortic dissection and aneurysm are rare but life-threatening complications after aortic valve replacement. Preoperative evaluation of risk factors such as aortic diameter, structural features of aortic wall, and associated diseases may decrease complication rate. We herein present analysis of risk factors of proximal aortic events following aortic valve replacement based on patient wi...

case presentation a 43-year-old man was referred to our institution for a severe aortic regurgitation and an ascending aorta enlargement associated with a relapsing sub-aortic membrane, which had been treated in his childhood. he underwent a redo ascending aorta replacement and an aortic valve replacement (mechanical prosthesis) along with a resection of the relapsing sub-valvular membrane. som...

Giant ascending aortic aneurysm formation following aortic valve replacement is rare. A 28-year-old man who underwent aortic valve replacement with a prosthetic valve for aortic regurgitation secondary to congenital bicuspid aortic valve about 10 years ago was diagnosed with a giant ascending aortic aneurysm about 16 cm in diameter in follow-up. The aneurysm was resected leaving the functional ...

BACKGROUND The presence of a fourth aortic valve cusp (quadricupsid aortic valve) is a rare congenital malformation and is often accompanied by other anomalies of the adjacent cardiovascular structures. Among these concomitant anomalies, simultaneous association of both a single coronary ostium and aneurysmal ascending aortic dilation in combination with the quadricupsid aortic valve has not be...

Four cases of patients with aortic incompetence secondary to rheumatoid arthritis are presented. All survived aortic surgery (two having bioprosthetic aortic valve replacement and two a homograft aortic root replacement). A review of the pathophysiology and pathology of this rare cause of aortic regurgitation is presented. A rationale for the choice of aortic valve prosthesis is discussed.

Between 1972 and 1978, 31 patients underwent replacement of the ascending aorta, with or without aortic valve surgery, at the Wessex Regional Cardiac Centre. The commonest indications for operation were aneurysmal dilatation of the ascending aorta causing aortic regurgitation and acute dissection of the ascending aorta. Eleven of the 31 patients had features of Marfan's syndrome. The overall ho...

OBJECTIVES The purpose of this study was to use transesophageal echocardiography (TEE) to define the mechanisms of aortic regurgitation (AR) in acute type A aortic dissection so as to assist the surgeon in identifying patients with mechanisms of AR suitable for valve preservation. BACKGROUND Significant AR frequently complicates acute type A aortic dissection necessitating either aortic valve...

global myocardial ischemia and ischemia-reperfusion injury are potential adverse events related with cardioplegic arrest. beating heart surgery has avoided such complications and adapted to valve surgery following successful results published on myocardial revascularization. difficulty in weaning from cardiopulmonary bypass may be lessened by using on-pump beating heart surgery for mitral valve...

Rheumatoid aortic valve disease is uncommon. and there are few reports of valve replacement in this condition. Aortic valve replacement and partial pericardiectomy was performed in a patient with acute rheumatoid aortitis and aortic incompetence. Previous reports suggest that any patient with rheumatoid arthritis who develops cardiac symptoms should be carefully assessed for surgically treatabl...

We have investigated the prevalence of hypertension and the response of blood pressure to operation in 87 patients with lone aortic valve disease who underwent aortic valve replacement. In patients with aortic stenosis alone 26% were hypertensive pre-operatively (age and sex adjusted blood pressure greater than 160 systolic and or greater than 95 mmHg diastolic) and 24% were hypertensive post-o...
