A 58-year-old man with Marfan syndrome visited our clinic for a routine examination. He had undergone a modified Bentall procedure with Carrel patch technique for annuloaortic ectasia 15 years previously. Computed tomography revealed an aneurysm of 43×57 mm in diameter at the right coronary ostium. He underwent resection of the aneurysm and coronary reconstruction using Piehler technique. He was discharged on the 37th postoperative day when his renal function recovered. Although the modified Bentall procedure may improve the surgical outcome, long-term follow-up is important because of various postoperative anastomotic complications in patients with Marfan syndrome.

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.

We present a case of an 82-year-old woman who developed sustained heart failure with left ventricular dyssynchrony after the modified Bentall procedure. Persistent circulatory instability and complete atrioventricular block suggested coronary artery stenosis. Multidetector computed tomography revealed stenosis of the grafted portion of the coronary artery.

Introduction: Sirolimus (SRL) mitigates cardiac allograft vasculopathy (CAV) progression and confers renal protection after heart transplantation (HT). However, its safety and efficacy in patients undergoing combined heart and kidney transplantation (HKT) are unclear. This study aimed to investigate the impact of conversion from calcineurin inhibitors (CNIs) to SRL on CAV progression, renal function, and outcomes in HKT compared with isolated HT.

Article Synopsis
- The BeSPoKE technique is a surgical method used to enlarge the aortic outflow tract in adults with complex heart issues, specifically those facing aortic stenosis and prosthesis-patient mismatch.
- A study involving 25 adults showed significant improvement in aortic valve gradients post-surgery, with a median size increase of the prosthesis and no reports of operative mortality.
- Postoperative complications included atrial fibrillation and heart block, but overall survival at two years was high at 92%, indicating that this technique is a safe and effective option for patients with small left ventricular outflow tracts.
