Combined Bentall and Modified Ravitch Procedures: A Case Report and Systematic Review of the Evidence

Background and Objectives: Marfan syndrome (MS) is a genetic disorder with autosomal dominant inheritance that affects the connective tissue and consequently many organ systems. The cardiovascular manifestations of MS are notorious and include aortic root dilatation or acute aortic dissection, which can cause morbidity and early mortality. However, surgical treatment of aortic pathology may be complicated by musculoskeletal deformity of the chest wall, as in pectus excavatum. In this regard, single-stage combined Bentall and Ravitch surgery is an extreme rarity that has also been scarcely reported in the literature. Patients and Methods: We present the medical history and single-stage Bentall and modified Ravitch surgical treatment of an 18-year-old male MS patient with symptomatic and severe pectus excavatum (PEX) in conjunction with a pear-shaped aortic root aneurysm. To discuss our case in the context of a synopsis of similar published cases, we present a systematic review of combined Bentall surgical aortic aneurysm repair and Ravitch correction of PEX. Results: A total of four studies (one case series and three case reports) and a case from our institution describing a single-stage combined Bentall and Ravitch operation were included. Patients were 22 ± 5.9 years of age (median = 22.5 years) and predominantly male (60%). All cases reported a midline vertical skin incision over the sternum. The most common surgical approach was midsternotomy (80%). In all cases metal struts were used to reinforce the corrected chest wall. Postoperative mortality was zero. Conclusions: Single-stage combined Bentall and Ravitch surgery is an underutilized surgical approach. Its use in MS patients with concomitant PEX and ascending aortic aneurysm that require surgical treatment warrants further investigation. Midsternotomy seems to be a viable access route that provides sufficient exposure in the single-stage surgical setting. Although operative time is long, the intraoperative and postoperative risks appear to be low and manageable.
