ABSTRACT
Papillary fibroelastoma (PFE) is the second most common type of benign cardiac tumor after myxoma, and is most commonly found in the left side of the heart. In this study, we report a case of PFE located in the tricuspid valve chordae. The patient was a 65-year-old woman in whom a heart murmur was detected during a routine medical examination. A follow-up examination identified a cardiac tumor, and she was subsequently referred to our medical department. Echocardiography and contrast-enhanced computed tomography indicated a mobile mass of approximately 1 cm in the right ventricle, and she was determined to be a candidate for surgery. After cardiopulmonary bypass, we instigated cardioplegic arrest, made an incision in the right atrium, and observed the right ventricle through the tricuspid valve. We observed a yellowish sea-anemone-like mass approximately 9 mm from the chordae of the anterior leaflet of the tricuspid valve. Thus, the mass was resected with the chordae and tricuspid annuloplasty. Postoperative progress was satisfactory, and the subject was discharged on the 19th day of hospitalization. Histopathological examination indicated a mixture of thick fibrous and adipose tissues, which led to the diagnosis of PFE. PFE is a relatively rare disease that comprises 8% of primary cardiac tumors. IA often occurs in the left heart and can cause cerebral infarction, myocardial infarction, and other symptoms of embolism. However, because small masses and those that occur in the right heart are not accompanied by clinical symptoms, such cases are often discovered during routine echocardiography. The present study reports a case of PFE that occurred in the tricuspid valve chordae that was diagnosed via echocardiography.
ABSTRACT
A 69-year-old man was admitted to our hospital due to cardiomegaly on plain chest radiography. He did not have any history of chest pain, trauma or fever of unknown origin. Echocardiography showed severe aortic valve regurgitation. Standard enhanced computed tomography (CT) showed a localized dissection or an aneurysm of the noncoronary sinus of Valsalva. However it is difficult to make a definite diagnosis because of cardiac beating artifact. Cardiac multidetecter-row CT demonstrated an aneurysm of the noncoronary sinus of Valsalva connected to the sinus with a small aperture. Aortic valve replacement and patch closure were performed. The postoperative course was uneventful and follow-up CT showed thrombus formation in the sinus Valsalva aneurysm. Cardiac multidetecter-row CT was useful for accurate diagnosis of aortic root disease.
ABSTRACT
A 26-year-old woman was referred to our hospital with a high fever and thrombocytopenia. The patient was initially given a diagnosis of disseminated intravascular coagulopathy and sepsis. Medial therapy with antibiotic and anticoagulative drug was started in the Department of Internal Medicine. After that, dermatologists identified painful nodular erythema on the face and extremities as Osler's nodes. Echocardiogram revealed a vegetation near the annulus of the mitral valve. The urgent operation was performed. Intraoperative findings showed vegetation on the posterior wall of the left atrium and normal mitral valves. Therefore, vegetation was completely excised with the diseased left atrial wall and the mitral valve was preserved. The defect of the atrial wall was repaired with a pericardial patch. Methicillin-resistant <i>Staphylococcus aureus</i> was detected by blood and tissue bacterial culture. Postoperative echocardiograms showed mild mitral regurgitation. The patient was discharged from hospital after an uneventful postoperative course.
ABSTRACT
The use of transapical aortic cannulation for arterial inflow during surgical repair of type A acute aortic dissection was evaluated. Thirty-six patients who underwent repair of type A aortic dissection were divided into 2 groups: those who underwent repair with transapical aortic cannulation (group A; 19 patients) and those who underwent repair with axillary and/or femoral artery cannulation (group C; 17 patients). Preoperative condition, estimated blood loss, transfusion requirements, and duration of the tube drainage and postoperative hospital stay did not differ in the 2 groups. Cannulations were successful in all patients, and none of the attempted inflow sites required moving to alternate sites in either group. The time to initiation of extracorporeal circulation (74.2±16.2min versus 88.8±12.5min, <i>p</i>=0.005) and the extracorporeal circulation time (175.2±55.5min versus 216.6±58.1min, <i>p</i>=0.036) was shorter in group A than in group C. However, the total operation time did not differ between the groups (309.3±112.5min in group A versus 363.4±130.9min in group C, <i>p</i>=0.198). All patients survived the operation, and there were no complications directly related to transapical aortic cannulation. Postoperative stroke tended to be lower in group A than in group C (5.3% versus 29.4%; <i>p</i>=0.081). There was 1 operative death in group A (5.3%) and 4 operative deaths in group C (23.5%) (<i>p</i>=0.167). These data demonstrate that the use of transapical aortic cannulation yielded more favorable results than other cannulation techniques for induction of extracorporeal circulation and for minimization of extracorporeal circulation time and postoperative morbidity. We conclude that transapical aortic cannulation represents a safe, effective and less invasive means of providing arterial inflow during cardiopulmonary bypass for patients undergoing surgical correction of type A aortic dissection.
ABSTRACT
A 63-year-old man with unstable angina and idiopathic thrombocytopenic purpura (ITP) underwent off-pump coronary artery bypass grafting after being admitted to our hospital because of angina pectoris. Coronary angiography performed on admission showed 90% stenosis of the left main coronary artery. High dose transvenous γ globulin therapy was performed for 3 days before surgery. The number of platelets, which was 2.3×10<sup>4</sup>/mm<sup>3</sup> on admission increased to 4.1×10<sup>4</sup>/mm<sup>3</sup> before surgery. Ten units of platelets were transfused intraoperatively, with little perioperative hemorrhage and no increased incidence of bleeding complications. The postoperative course was uneventful. High dose transvenous γ globulin therapy and operation without cardiopulmonary bypass were useful in facilitating the treatment of this ITP coronary artery bypass patient.
ABSTRACT
A 72-year-old woman complaining of lumbago was transferred to our hospital in a state of shock. An admission abdominal CT scan showed infrarenal aortic aneurysm reaching 8cm in maximal diameter and hematoma of the retroperitoneal space. A clinical diagnosis of ruptured abdominal aortic aneurysm was rapidly established. An emergency operation was performed under general anesthesia. Laparotomy disclosed an infrarenal abdominal aortic aneurysm and hematoma. The aorta was clamped just below the bilateral renal arteries. Straight graft replacement was performed. There was enough heparinization during the surgical procedure. Postoperative findings involved paraplegia and hypoesthesia from dermatome Th 10 with associated urinary and fecal incontinence. The patient was discharged from our hospital. Spinal cord ischemia is a rare and unpredictable complication in surgery of infrarenal abdominal aortic aneurysms. Presence of intra- and postoperative episodes of hypotension and the duration of the crossclamping seem to have been the most important factors for spinal cord ischemia in this case.
ABSTRACT
We report a case of rupture of the thoracic descending aorta due to blunt chest trauma. An 18-year-old man was transferred to our hospital after a car accident. He was in a state of shock. The admission chest X-ray film demonstrated mediastinal widening and blurring of the aortic arch. Chest and abdominal helical CT scan showed left hemothorax, pseudoaneurysm, and hematoma of the cervix, mediastinum, and retroperitoneal space. We diagnosed rupture of the thoracic descending aorta without other injuries. An emergency operation was performed under partial cardiopulmonary bypass with systemic heparinization. The descending aorta had completely lost its continuity. Graft replacement was performed with a collagen-sealed woven Dacron graft. The postoperative course was uneventful. We suggest that high awareness and a systematic approach are needed to diagnose traumatic aortic rupture, and that enhanced helical CT scanning is helpful for diagnosis and management strategy.
ABSTRACT
CHDF was applied to 8 patients who developed acute renal failure following cardiogenic shock. Four of 8 patients also underwent PCPS (percutaneous cardiopulmonary bypass) and all were weaned from PCPS. Five patients were weaned from CHDF. CHDF was very effective to control the concentration of serum potassium, creatinine, blood urea nitrogen and diuresis.
