Abstract Background The Ross procedure is a technically complex operation to address the pathology of the aortic valve. Prior attempts at widespread implementation have been plagued with variations in effectiveness. We report our initial programmatic outcomes using dissemination and implementation (D&I) science frameworks, with an aim to define both programmatic efficacy and effectiveness. The study design was a single center, explanatory sequential mixed methods evaluation of a Ross surgery program from June 2020 to April 2023. Quantitative measures for baseline patient characteristics and postoperative outcomes were summarized. Qualitative measures were obtained using semi-structured interviews and characterized using implementation science frameworks. Results A total of 71 patients underwent the Ross procedure at a single academic center. Mean age was 40 years (± 13). There were no perioperative deaths or valve-related reinterventions (0%). During the follow-up period, 2 (2.8%) patients required re-operation and 2 (2.8%) required balloon dilation of the pulmonary homograft. Qualitative measures noted communication and prospective self-audit facilitated measures of effectiveness, as dichotomy within expected vs. observed outcomes led to program modifications. Collaboration across hospital systems promoted adoption and implementation, which led to the incorporation of the Ross procedure into accepted organizational practice. Conclusions In this formative evaluation, limited-efficacy outcomes demonstrated similar programmatic success to data from other established centers. With the prerequisite center volume and case selection, the Ross procedure is a safe and efficacious treatment for aortic valvular disease. Implementation science can be used both in real-time and retrospectively to guide organizational efforts to improve outcomes and to improve the translation of results across centers.

Background: The Ross procedure is a technically complex operation to address the pathology of the aortic valve. Prior attempts at widespread implementation have been plagued with variations in effectiveness. We report our initial programmatic outcomes using dissemination and implementation (D&I) science frameworks, with an aim to define both programmatic efficacy and effectiveness.

We report the case of a redo Ross surgery complicated by an ostial left circumflex occlusion requiring emergent percutaneous coronary intervention. The latter was complicated by coronary perforation treated by two covered stents with V-stenting technique. After immediate success, the clinical course was marked by acute stent thrombosis requiring emergent coronary bypass. Ostial left circumflex perforation is a rare and potentially fatal complication that is challenging to manage. V stenting technique with two covered stents could be used as a life-saving procedure, but is associated with a high thrombotic risk. [ABSTRACT FROM AUTHOR]
