Patient-specific access planning in minimally invasive mitral valve surgery

Early results of female patients who underwent mitral valve surgery through periareolar incision approach

BACKGROUND

Approaches that require less invasive procedures, offer heal in a shorter time and provide better cosmetic results have gained importance with the technological and modern developments in cardiac surgery. Esthetically preferred results can be achieved after heart valve surgery using a periareolar incision, especially in female patients. In the present study, we aimed to present our results after surgery using periareolar incision in female patients.

METHODS

We retrospectively evaluated the 1-year follow-up results in the postoperative period of isolated mitral valve replacement and tricuspid valve repair with mitral valve replacement using a periareolar incision with direct observation in 32 patients between 2020 and 2023. At the end of 1-year follow-up, we evaluated the patients' visual satisfaction with the incision site using a visual analog scale.

RESULTS

According to the postoperative follow-up results, no prosthetic mitral valve dysfunction was detected in any of the patients at the 1st year echocardiography controls. Mild tricuspid valve insufficiency was detected in 3 patients who underwent tricuspid valve repair. Besides, a high level of satisfaction was observed in the patients' incision site evaluations with a visual analog scale at the end of the first year, and no numbness was reported in the periareolar region in any of the patients.

CONCLUSION

Our study shows that surgical results similar to conventional methods can be achieved with the periareolar approach, and patient satisfaction and recovery times are shorter and more satisfying. We also think that the periareolar incision can be made without videoassisted equipment and this may reduce the surgical cost.

Mitral valve surgery assisted by virtual and augmented reality: Cardiac surgery at the front of innovation

BACKGROUND

Given the variety in mitral valve (MV) pathology and associated surgical techniques, extended reality (XR) holds great potential to assist MV surgeons. This review aims to systematically evaluate the currently available evidence investigating the use of XR and associated technologies in MV surgery.

METHODS

A systematic database search was conducted of original articles and case reports that explored the use of XR and MV surgery in EMBASE, MEDLINE, Cochrane database and Google Scholar, from inception to February 2022.

RESULTS

Our search yielded 171 articles, of which 15 studies were included in this review, featuring 328 patients. Two main areas of application were identified: (i) pre-operative planning and (ii) predicting post-operative outcomes. The articles reporting outcomes relating to pre-operative planning were further categorised as exploring themes relevant to (i) mitral annular assessment; (ii) training; (iii) evaluation of surgical technique; (iv) surgical approach or plan and (v) selecting ring size or type. Preoperatively, XR has been shown to evaluate mitral annular pathology more accurately than echocardiography, informing the surgeon about the optimal surgical technique, approach and plan for a particular patient's MV pathology. Furthermore, XR could simulate and aid ring size/type selection for MV annuloplasty, creating a personalized surgical plan. Additionally, XR could estimate the postoperative MV biomechanical and physiological characteristics, predicting and pre-empting post-operative complications.

CONCLUSION

XR demonstrated promising applications for assisting MV surgery, enhancing outcomes and patient-centred care, nevertheless, there remain the need for randomized studies to ascertain its feasibility, safety, and validity in clinical practice.
