Anomalous papillary muscles (PMs), in which the PMs are directly attached to the anterior mitral valve (MV) leaflet, can cause obstruction of the left ventricular outflow tract (LVOT). Accurately diagnosing of anomalous PMs, understanding their pathology, and performing appropriate surgery are essential for relieving LVOT obstruction effectively. A 71-year-old man with hypertrophic obstructive cardiomyopathy was referred to our hospital. Transthoracic echocardiography revealed LVOT obstruction with a peak outflow pressure gradient of 63 mm Hg at rest and 96 mm Hg during the Valsalva maneuver. Furthermore, an anomalous PM was suspected to be the cause of LVOT obstruction. Three- and four-dimensional cardiac computed tomography (CT) images clearly demonstrated that an anomalous PM from the anterior PMs was directly attached to the body of the anterior MV leaflet and that the anomalous PM, together with the thickened ventricular septum, caused a dynamic obstruction of the LVOT. We resected the anomalous PM from the anterior PMs and the subaortic ventricular septum using a transaortic approach. In this case, preoperative three-dimensional and four-dimensional cardiac CT images were effective at revealing the presence of an anomalous PM and its pathology in patient with LVOT obstruction, leading to accurate and smooth surgical procedures and improved patient outcomes. Learning objective: • Anomalous PMs are classified by their attachment patterns and appropriate surgical methods are recommended for each type, providing valuable insights for clinical decision-making. • This report emphasizes the significance of 3D and 4D cardiac CT in identifying the causes of LVOTO. This imaging technique provides important information regarding the location of the anomalous PM and dynamic impact, leading to a successful surgical outcome.

An 84-year-old man, who attempted suicide, sustained injuries from nails driven into his head and the anterior thoracic region by a nail gun. A computed tomography scan revealed residual nails, along with cardiac, pulmonary, and brain injuries. The patient underwent immediate cardiac surgery and craniotomy. No apparent damage to the pericardium was observed. However, the presence of dark red changes oozing near the apex of the heart was noted. These intraoperative findings suggested the possibility of blunt cardiac injury resulting from the impact of the nail gun. While injuries to organs other than the limbs caused by a nail gun are uncommon, the severity of such injuries can vary from asymptomatic to hemodynamic failure. In cases involving thoracic wounds, not only penetrating trauma but also the occurrence of blunt cardiac injury could remarkably worsen the patientʼs overall condition. Therefore, immediate evaluation and treatment are important to save the patientʼs life.
