Extended septal myectomy versus alcohol septal ablation: clinical results at a national referral centre.

Objectives: Extended septal myectomy and alcohol septal ablation are 2 invasive treatments for hypertrophic obstructive cardiomyopathy. Our goal was to compare which of these techniques achieved a higher reduction in gradients, improvement in New York Heart Association (NYHA) functional class and reduction in medical treatment.

Methods: It is a single-centre observational and retrospective analysis.

Aortic valve reimplantation in patients with connective tissue syndromes: A 15-year follow-up.

Objectives: The goal of this study was to analyse early- and long-term outcomes of aortic valve reimplantation (David operation) in patients with heritable thoracic aortic disease.

Methods: This is a retrospective observational analysis using data from a prospectively maintained surgical database from March 2004 to April 2021. Patients with heritable thoracic aortic disease were included in the study.

Are 18F-fluorodeoxyglucose positron emission tomography results reliable in patients with ascending aortic grafts? A prospective study in non-infected patients.

Objectives: Our goal was to define characteristic patterns of 18F-fluorodeoxyglucose in non-infected patients with ascending aortic prosthetic grafts during the first year after surgery.

Methods: 18F-fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT) was performed at 3, 6 and 12 months postoperatively in 26 uninfected patients. Clinical, analytical and microbiological (blood culture) assessments were performed to confirm the absence of infection.
