AI Article Synopsis
- The Robicsek procedure is designed for patients with dilation of the ascending aorta and aortic valve disease, examining its short to mid-term outcomes after surgery.
- A study involving 30 patients showed successful outcomes with no hospital deaths, and the average aortic diameter decreased significantly during an 18-month follow-up.
- The Robicsek operation offers advantages over other surgical options, like the Bentall and David procedures, by providing effective results with shorter surgery times and lower risks for patients with the condition.
Article Abstract
Objective: To introduce the Robicsek procedure and summarize its short to mid-term results for patients with dilatation of the ascending aorta associated with aortic valve disease.
Methods: From December 2002 to June 2006, 30 patients with a moderately dilated ascending aorta [mean diameter, (46.7+/-3.1) mm] underwent concomitant aortic valve replacement (AVR) or repairing and reinforced aortoplasty with a well-tailored Dacron vascular graft. Follow-up was obtained on all patients with ultrasonic cardiography (UCG) or computed tomography (CT) scan and was (18.0+/-10.5) months.
Results: The total average cardio-pulmonary bypass (CPB) time was (103.4+/-21.7) min (80-151 min), and aortic arrest time was (73.0+/-21.6) min (48-120 min), whereas the average CPB time and aortic arrest time of 19 patients who underwent the isolated Robicsek procedure were only (91.3+/-8.9) min (80-118 min) and (61.6+/-11.3) min (48-82 min). No mortality occurred in the hospital. During follow-up of 18 months, no recurrent ascending aortic dilatation and dissection were observed, and the average aortic diameter was reduced to (33.7+/-2.5) mm. Sixteen of the 30 patients were diagnosed as bicuspid aortic valve (BAV). The ascending aortic media were histologically abnormal in 23 patients.
Conclusion: Considering the underlying wall deficiency and the homodynamic stress, the Robicsek operation should be an optimal choice to those patients with a mild to moderate dilated ascending aorta caused by aortic valve lesion. Compared with the Bentall and David procedures, the Robicsek procedure could achieve the same or even better clinical results with less operative time and risks.

Computed tomography (CT)-derived Epicardial Adipose Tissue (EAT) is linked to cardiovascular disease outcomes. However, its role in patients undergoing Transcatheter Aortic Valve Replacement (TAVR) and the interplay with aortic stenosis (AS) cardiac damage (CD) remains unexplored. We aim to investigate the relationship between EAT characteristics, AS CD, and all-cause mortality.

Background: Untreated severe heart valve disease (HVD) is associated with premature mortality. Research shows low population awareness of when to seek assessment and low focus on cardiac auscultation by physicians in primary care settings. We studied contemporary public knowledge of HVD and assessment by their general practitioner (GP) in Australia.

The volume of transcatheter aortic valve implantation (TAVI) for treatment of isolated aortic stenosis has far surpassed surgical aortic valve replacement (SAVR). There has been a consequent increase in TAVI explantation, now the fastest growing cardiac surgical procedure. Transcatheter heart valve explantation can be technically complex, with higher perioperative morbidity and mortality than routine SAVR or valve-in-valve TAVI.

Objective: We present our experience with endovascular Bentall procedure (Endo-Bentall) using a modular valve conduit (Endo-Bentall) in high-risk patients with aortic root pathologies.
Methods: The physician constructed Endo-Bentall device is composed of a self-expanding transcatheter aortic valve (TAVR), aortic endovascular stent graft (TEVAR), and two wire-reinforced fenestrations for coronary artery stenting. The TAVR valve is sutured into an appropriately sized TEVAR graft.

Objective: Over 30% of patients presenting with acute type A aortic dissection (ATAAD) are considered high - risk or inoperable. This study aims to investigate the early and mid-term outcomes of complex endovascular aortic repair of aortic root, ascending aorta, and aortic arch among patients with ATAAD.
Methods: From January 2018 to January 2023, 29 patients who were considered high risk for open operation underwent endovascular aortic repair.
