It requires balancing adequate myocardial excision against the risk of excessive resection, which can result in an iatrogenic ventricular septal defect. To our knowledge, this is the first reported case of a high-risk septal myectomy in complex anatomy W-shaped hypertrophic obstructive cardiomyopathy with a deep interventricular septum crypt and apical aneurysm. CT angiography\u2013based three-dimensional modeling of the interventricular septum and a virtual myectomy enabled detailed preoperative planning and successful surgery. This planning also informed the choice of a combined transaortic and transapical surgical approach tailored to the patient\u2019s anatomy.<\/jats:p>\n                  <jats:p>Keywords: CT
