[A successful surgical repair of ventricular septal perforation, whose perforated position could be marked by Swan-Ganz catheter before the operation].

The patient was a 72-year-old woman who was admitted with AMI. On the next day, a systolic murmur of Levine II/VI became audible on the left sternal border of the 5th intercostal space and VSP was diagnosed by the echocardiogram. The hemodynamics was comparatively stable, and so we scheduled the elective operation in the expectation of the healing of the infarction tissue. At the cardiac catheterization just before the operation, L-R shunt ratio was 64.9% and main PA was 41/18 (26) mmHg. Before the operation we marked the VSP position by Swan-Ganz catheter through the left ventricle and VSP closure and 2 CABG was performed. We concluded that this method was useful for the diagnosis and therapy of VSP.
