Purpose : The transaortic approach is the most common method of septal myectomy; however, difficulties arise due to a limited view of the surgical field. Here, we have reported our experience with videoscope-assisted transaortic myectomy.
Methods : A total of 10 patients underwent videoscope-assisted transaortic myectomy from January 2016 to July 2019 at OOOO Hospital, Seoul, South Korea. The preoperative data, echocardiographic images, operative records, and postoperative outcomes of these patients were reviewed.
Results : The mean patient age was 44.7 ± 11.8 years. The main indications for videoscope-assisted transaortic myectomy were midventricular septal muscle resection (70%), abnormal papillary muscle resection (40%), and abnormal chordal connection resection (30%). Eight (80 %) patients had multiple reasons for videoscope-assisted transaortic myectomy. There was no surgical mortality. Postoperatively, all patients showed mitral regurgitation less than moderateand New York Heart Association class . The mean peak pressure gradient decreased from 58 ± 43 mmHg to 18.9 ± 14.0 mmHg (p = 0.036) postoperatively.
Conclusion : Videoscope-assisted transaortic myectomy is an effective surgical technique in selective hypertrophic cardiomyopathy patients with complex intraventricular anatomy, diffuse hypertrophy, and midventricular obstruction.
