[Aberrometry in the diagnosis and treatment of keratoconus].

Keratoconus (KC) is a bilateral progressive disease that often begins in young adulthood. Advanced KC significantly impairs patients' quality of life, making early detection of the condition a critical goal for specialists. Early identification of KC greatly influences both the treatment strategy and the outcomes.

Right anterior thoracotomy vs. upper hemisternotomy for aortic valve replacement with Perceval S: is there a difference?

Background: Our study aimed to evaluate the early outcomes of aortic valve replacement with Perceval S sutureless valve through the right anterior thoracotomy and upper hemisternotomy approaches, and to determine if there are any differences between these two approaches.

Methods: We carried out a study using data from 174 patients who underwent minimally invasive Perceval S valve implantation for aortic valve stenosis between January 2018 and August 2023. This was a retrospective, single-center observational study.

Calcified amorphous tumor of the posterior mitral annulus.

Unlabelled: A 73-year-old male with a history of hypertension, congenital kidney aplasia, status post-myocardial infarction, stroke, and chronic renal insufficiency was admitted to our institute due to coronary artery bypass grafting. Preoperative echocardiogram revealed a 15 × 7 mm mass arising near the posterior mitral annulus. Following the coronary artery bypass grafting, the left atrial cavity was explored using a 30° endoscope.

Fatal hyperacute left main thrombosis after aortic root surgery.

Acute aortic root thrombosis is a potentially lethal condition due to the possibility of thrombosis into the ascending aorta branches, resulting in various clinical manifestations. A 29-year-old male patient was admitted to our center with hyperacute left main thrombosis after elective Bentall procedure. Due to massive left ventricular infarction, the patient was supported by extracorporeal membrane oxygenation, but without success to recovery.

Early outcomes of aortic valve replacement with Perceval PLUS sutureless valve: results of the prospective multicentric MANTRA study.

Background: The aim of this study is to report the preliminary real-word clinical and hemodynamic performance from the MANTRA study in patients undergoing aortic valve replacement with Perceval PLUS sutureless valve.

Methods: MANTRA is an ongoing "umbrella" prospective, multi-center, international post-market study to collect real-life safety and performance data on Corcym devices (Corcym S.r.
