Do anomalous aortic origin of a coronary artery patients have higher risk of myocardial ischaemia and adverse cardiac events during aortic and mitral valve replacements?

Objectives: We assessed the effect of anomalous aortic origin of a coronary artery on the risk of early and late postoperative events after aortic or mitral valve replacement in adults.

Methods: Between 2005 and 2022, 29,579 adults underwent surgical aortic or mitral valve replacement at Cleveland Clinic. Among these, 29 had an unrepaired coronary artery rising anomalously from the aorta that was not intervened upon during valve surgery, 19 (65%) an anomalous circumflex, and 9 (31%) an anomalous right.

Long-term outcome of bicuspid aortic valve repair using figure-of-8 hitch-up stitches.

Objective: To maximize successful repair of bicuspid aortic valves by adding figure-of-8 hitch-up stitches at commissures.

Methods: From 2000 to 2022, bicuspid aortic valve repair was performed on 1112 patients at Cleveland Clinic, with 367 patients receiving figure-of-8 hitch-up stitches along with classical techniques, including Cabrol suture, cusp plication, raphe resection, and valve-sparing root replacement. Operative outcomes, repair durability, and survival were assessed in the figure-of-8 hitch-up stitches cohort, and outcomes were compared among 195 balancing-score-matched patient pairs who underwent bicuspid aortic valve repair with and without figure-of-8 hitch-up stitches.

Efficacy and safety of a transaortic approach to midventricular and apical septal myectomy.

Objective: The study objective was to evaluate the safety and efficacy of a transaortic approach to midventricular and apical septal myectomy in patients with hypertrophic cardiomyopathy with left ventricular outflow tract or midventricular obstruction.

Methods: From January 2018 to August 2023, 940 patients underwent transaortic septal myectomy at the Cleveland Clinic, of whom 682 (73%) had midventricular or apical resection. Patients who underwent isolated basal myectomies were excluded.

Contemporary experience with the Commando procedure for anterior mitral anular calcification.

Objective: Anterior mitral anular calcification, particularly in radiation heart disease, and previous valve replacement with destroyed intervalvular fibrosa are challenging for prosthesis sizing and placement. The Commando procedure with intervalvular fibrosa reconstruction permits double-valve replacement in these challenging conditions. We referenced outcomes after Commando procedures to standard double-valve replacements.
