AI Article Synopsis
- * An 82-year-old woman with severe aortic stenosis underwent TAVI, but two days later, she suffered a sudden aortic dissection and unfortunately passed away.
- * The case highlights that patients with aortic root dilation are at risk for delayed aortic dissection following TAVI, emphasizing the need for careful pre- and post-operative monitoring.
Article Abstract
Background: Transcatheter aortic valve implantation (TAVI) has been established as an effective and safe treatment for patients with severe aortic stenosis (AS). It is reported that vascular complications, especially aortic dissection, are rare. However, aortic dissection may be a serious consequence if it occurs. We experienced a case of delayed onset of ascending aortic dissection after TAVI.
Case Summary: An 82-year-old woman presented with dyspnoea and general fatigue. Echocardiography revealed severe AS and she was diagnosed with heart failure associated with AS. She had difficulty controlling heart failure and required the intervention of the aortic valve. We evaluated the aortic valve and access routes with contrast-enhanced computed tomography (CT), which showed marked dilatation of the ascending aorta. Transcatheter aortic valve implantation was performed and the procedure was completed without major complications. Transoesophageal echocardiography during the procedure did not detect any obvious arterial injury. However, on the second postoperative day, the patient suddenly became unconscious and a CT indicated an ascending aortic dissection. Unfortunately, she passed away. An autopsy revealed the fragility of the ascending aorta.
Conclusion: Patients with AS and aortic root dilatation may develop delayed onset of ascending aortic dissection after TAVI.

Objective: The risk of aortic dissection is increased in Turner Syndrome (TS). Aortic dilation is thought to contribute to this risk and may be managed with elective aortic surgery. New TS guidance has lowered the aortic size thresholds for consideration of aortic surgery.

Background: Acute type A aortic dissection (ATAAD) has a high mortality, and acute aortic repair is the only curative treatment. In patients treated with factor Xa (FXa) inhibitors, the risk of severe disease-related complications such as cardiac tamponade and hemodynamic shock must be balanced against the potential for severe perioperative bleeding. The aim was to study intraoperative changes in plasma levels of the FXa inhibitor apixaban when using hemoadsorption during acute thoracic aortic repair.

Background The effect of surgeons' years of experience on the outcomes of acute type A aortic dissection (ATAAD) repair has not yet been studied. This study aimed to evaluate the association between the surgeon's years in practice and the outcomes of ATAAD repair. Methods Surgical records of ATAAD repairs performed at Saga University Hospital between 2004 and 2020 were reviewed.

BACKGROUND Acute intramural hematoma (IMH) of the ascending thoracic aorta and aortic arch is a life-threatening condition, particularly in elderly patients with comorbidities, due to its risk of progression and rupture. Unlike aortic dissection, IMH lacks an intimal tear, influencing both clinical presentation and treatment strategy. This report describes a 74-year-old hypertensive woman with type A IMH and a penetrating atherosclerotic ulcer (PAU), managed with a hybrid surgical approach that combines external Dacron wrapping of the ascending aorta and endovascular stenting of the aortic arch with in-situ fenestration of the supra-aortic arteries.
