Key result
Two-port thoracoscopic aortic valve replacement achieved a 100% procedural success rate with 0% in-hospital mortality and no major complications in patients with pure aortic valve disease.
Why the study?
While minimally invasive cardiac surgery is widely used for atrioventricular valve lesions, totally thoracoscopic aortic valve replacement has rarely been reported.
Does two-port thoracoscopic aortic valve replacement improve procedural success and safety in adult patients with pure aortic valve diseases?
Observational (n=9)
No
Does two-port thoracoscopic aortic valve replacement improve procedural success and safety in adult patients with pure aortic valve diseases?
Two-port thoracoscopic aortic valve replacement is a feasible and safe minimally invasive surgical option for carefully selected patients with pure aortic valve disease, yielding excellent short-term outcomes.
Small retrospective series suggests technical feasibility of two-port thoracoscopic AVR; leaves open need for larger prospective trials versus sternotomy.
BACKGROUND: Pure aortic valve disease is common and has been treated with sternotomy aortic valve replacement for decades. Minimally invasive cardiac surgery has been widely used in atrioventricular valve lesions, but totally thoracoscopic aortic valve replacement has rarely been reported. METHOD: The profiles of 9 patients who were diagnosed with severe aortic valve diseases and treated with two-port thoracoscopic aortic valve replacement between February 2021 and February 2022 were retrospectively reviewed. The clinical data, including baseline characteristics, operative data, postoperative complications, and short-term outcomes, were reported. RESULTS: All nine patients successfully underwent two-port thoracoscopic aortic valve replacement, with a cardiopulmonary bypass time of 137.56 ± 27.99 min and an aortic cross-clamp time of 95.33 ± 17.96 min. Seven (77.78%) patients underwent mechanical valve replacement, and two (22.22%) patients underwent bioprosthetic valve replacement. Two (22.22%) patients underwent a concomitant aortic root enlargement procedure. There were no intraoperative or postoperative deaths. The incidence of procedural complications was 0%, while the results of ventilation time, intensive care unit stay length, blood transfusion, chest tube drainage, and kidney function were satisfactory. CONCLUSION: Two-port thoracoscopic aortic valve replacement is a safe and effective surgical treatment option for carefully selected patients with pure aortic valve diseases.

Tan et al. (2023) conducted an observational in Pure aortic valve disease (n=9). Two-port thoracoscopic aortic valve replacement was evaluated on Procedure success rate, in-hospital mortality, and occurrence of adverse effects. Two-port thoracoscopic aortic valve replacement achieved a 100% procedural success rate with 0% in-hospital mortality and no major complications in patients with pure aortic valve disease.
