    Abstract

    A calcified amorphous tumor (CAT) of the heart is a rare, non-neoplastic, intracavitary cardiac mass. Histological examination reveals the presence of calcified and amorphous fibrous material with underlying chronic inflammation. Some studies have reported that CAT typically exhibits rapid growth. However, we observed a case in which CAT unexpectedly ruptured within approximately two weeks. There was no cerebral infarction or significant valvular disease, therefore we were not sure about the indication for surgery; however considering the epidemiological possibility of CAT, we decided to operate and were able to treat the patient without complications.

  • A case of minimum invasive debranch thoracic endovascular aortic repair for isolated left vertebral artery: complete revascularization without artificial vessels via a single small incision Reviewed

    Abstract

    Isolated left vertebral artery (ILVA) is one of the most frequent vertebral abnormalities. When performing thoracic endovascular aortic repair (TEVAR), the ILVA may have to be closed depending on the position of the stent graft; in these cases, the decision to reconstruct the ILVA depends on the state of cerebral blood flow. Here, we report a case of a 68-year-old male, in whom the Willis arterial circle was incomplete; we therefore performed a reconstructive method during zone 2-landing TEVAR that ensured ILVA and left subclavian artery blood flow without the use of artificial vessels. Only one supraclavicular incision was required for reconstruction. This method has some procedural difficulties; however, it does not use artificial blood vessels and can be performed with a single incision.

    Abstract

    A 78-year-old man underwent pericardial patch repair for left ventricular (LV) rupture during mitral valve replacement. After the first operation, a huge (>10 cm) LV pseudoaneurysm was detected, necessitating reoperation. LV rupture is a rare but often fatal complication of mitral valve replacement. Although repair of LV rupture during mitral valve replacement has been reported, the development of pseudoaneurysm after such repair is exceedingly rare. In this case, we successfully treated a huge LV pseudoaneurysm using two pericardial patches to sandwich the rupture hole from the inside.
