ABSTRACT

Triple-vessel disease of coronary artery was recognized in the examination of a 78-year-old man when hemodialysis was introduced for diabetic nephropathy. Percutaneous coronary intervention (PCI) was performed as initial treatment for the lesion of the right coronary artery. Contrast CT was performed because of persistent fever from the first day after the PCI. Since the tumor occupying the inside of the left atrium which was not found before PCI we were concerned about the failure of the hemodynamics and decided to treat it surgically. Surgery was performed with off-pump coronary artery bypass grafting, followed by left atrial mass removal surgery under cardiac arrest using cardio-pulmonary bypass. When examining the interior of the left atrium with a right lateral incision of the left atrium, the tumor was found to be on the posterior wall. This surface was smooth, and there was no endometriosis or hematoma. After incising the left atrial adventitia, old hematoma was found in the inside of the left atrium muscle layer, and it was removed as much as possible. The left atrial tumor was actually an intramural hematoma, based on image findings and macroscopic findings. Searching for the cause retrospectively, it was thought that the wire which was displaced during PCI was the cause of bleeding. We confirmed that there was no recurrence of left atrial intramural hematoma on an outpatient visit on the 113th postoperative day. We report a rare case of removing left atrial intramural hematoma under cardiac arrest which appeared after PCI.

ABSTRACT

The surgical outcome is worse when VSP is attempted soon after myocardial infarction due to the more poor general condition, preoperative cardiogenic shock, fragile infarcted myocardial tissue. We successfully rescued a 80-year cardiopulmonary arrest patient who was suffering from subacute postinfarcted VSP complicated by the left ventricular aneurysm. The VSP was closed with the sandwich patch technique approached from both ventricles. The left ventricular aneurysm was repaired with endoventricular circular patch plasty.

ABSTRACT

Congenital quadricuspid aortic valve is a very rare malformation. Most cases have been discovered as an incidental finding at aortic valve surgery or at autopsy. It frequently evolves to aortic regurgitation, which can manifest in adulthood and may require surgical treatment. A 66-year-old man was admitted because of dysprea. Echocardiogram revealed aortic regurgitation, mitral regurgitation, and tricuspid regurgitation. We performed aortic valve replacement, mitral annuloplasty, and tricuspid annuloplasty successfully. The aortic valve showed one large, two intermediate and one smaller cusp, which were classified as typed by Hurwitz's classification. An accessory cusp was situated between the right and left coronary cusps. No coronary abnormality was involved. The postoperative course was uneventful and he is doing well 6 months after operation.

ABSTRACT

In the presence of Leriche syndrome, the lower extremities are perfused by collateral flow from internal mammary arteries. If an internal mammary artery graft is used in coronary artery surgery, an acute ischemic limb will develop postoperatively. A 52-year-old man was admitted to our department with bilateral claudication. Multidetector row computed tomography with contrast showed total occlusion of the infrarenal abdominal aorta and rich collateral flow to the lower extremities from internal mammary arteries. Cardiac angiography revealed three-vessel disease. Simultaneous coronary artery bypass grafting and an ascending aorto-bifemoral bypass were performed without cardiopulmonary bypass. Postoperative computed tomography angiography showed that grafts to the coronary and bifemoral arteries were patent. This combined procedure is useful for patients with coronary artery disease and aortoiliac occlusive disease. This procedure without cardiopulmonary bypass has not previously been reported.

ABSTRACT

A 62-year-old woman with idiopathic thrombocytopenic purpura (ITP) was admitted to undergo cardiac surgery for aortic stenosis, angina pectoris, and paroxysmal atrial fibrillation. A bleeding tendency was expected due to the dramatic decrease in platelets during cardiopulmonary bypass. We performed high-dose transvenous gammaglobulin infusion (400mg/kg/day) for 5 consecutive days immediately before surgery. The gammaglobulin therapy caused steady increase of thrombocytes from 4 days after surgery, even though the platelet count showed no significant change preoperatively. The postoperative course was satisfactory with neither a bleeding tendency nor wound infection. High-dose transvenous gammaglobulin therapy is thus useful for perioperative patients with accompanying ITP, who are often under medication with steroids. This therapy is also effective for prevention of infection.
