[Surgical Resection Papillary Fibroelastoma Arising from Left Atrium:Report of a Case].

Kyobu Geka 2021 Oct;74(11):967-971

Department of Cardiovascular Surgery, Jichi Medical University Saitama Medical Center, Saitama, Japan.

A 75-year-old man was admitted for cerebral infarction. Magnetic resonance imaging revealed parietal lobe cerebral infarction. Transesophageal echo and contrast-enhanced computed tomography indicated mobile and speckled mass arising from left atrium. He was diagnosed with cardiogenic cerebral embolism. Under cardiopulmonary bypass, resection of the mass including endocardium tissue was per formed. The resected specimen showed multiple small fronds resembling a sea anemone. Microscopic examination showed multiple branching fronds of paucicellular and avascular fibroelastic tissue lined by a single layer of endocardium. Pathological diagnosis was papillary fibroelastoma. Three years passed without recurrence.

[Subacute Pseudoaneurysm Formation after Sutureless Repair for Postinfarction Left Ventricular Rupture:Report of a Case].

Kyobu Geka 2021 Sep;74(9):697-700

Department of Cardiovascular Surgery, Jichi Medical University Saitama Medical Center, Saitama, Japan.

A 71-year-old woman was admitted for cardiac tamponade due to left ventricular free wall rupture after acute myocardial infarction. Sutureless repair was performed for bleeding from the inferior wall. Fifteen days later, computed tomography demonstrated enlargement of a left ventricular pseudoaneurysm. Patch closure using a vascular prosthesis was performed through left thoracotomy. No recurrence of the left ventricular aneurysm has been observed since.

[Rapid Growing Thoracic Aortic Aneurysm in a Patient with Relapsing Polychondritis].

Kyobu Geka 2021 Aug;74(8):583-586

Department of Cardiovascular Surgery, Jichi Medical University Saitama Medical Center, Saitama, Japan.

A 26-year-old man with relapsing polychondritis was admitted for the treatment of multiple thoracic aortic aneurysms in the ascending and descending aorta. Descending thoracic aortic aneurysm showed rapid expansion, therefore, the patient underwent an extended thoracic aortic repair from the ascending aorta to the descending aorta via anterolateral thoracotomy and partial sternotomy. Although postoperative course was uneventful, aortic root enlargement and severe aortic insufficiency progressed over the next two years. He and his family refused redo surgical intervention and the patient died of heart failure. Careful perioperative follow-up may be mandatory in a patient with relapsing polychondritis complicated by cardiovascular disease.

[Bioprosthetic Mitral Valve Thrombosis in Patient with Antiphospholipid Antibody Syndrome;Report of a Case].

Kyobu Geka 2020 Aug;73(8):619-622

Department of Cardiovascular Surgery, Jichi Medical University Saitama Medical Center, Saitama, Japan.

A 66-year-old woman with primary antiphospholipid antibody syndrome (APS) was admitted due to severe dyspnea. Eight months prior to admission, she underwent bioprosthetic mitral valve replacement for mitral valve stenosis and regurgitation. Transthoracic echocardiogram showed thickening bioprosthetic valve leaflets and severe valve stenosis. Emergency reoperation for artificial valve failure was performed. The explanted bioprosthetic valve showed massive thrombus formation. After the operation, she started strict anticoagulant and antiplatelet therapies and was discharged without recurrence of valve thrombosis.

Acute Kidney Injury Following Elective Open Aortic Repair with Suprarenal Clamping.

Ann Vasc Dis 2020 Mar;13(1):45-51

Department of Cardiovascular Surgery, Saitama Medical Center, Jichi Medical University, Saitama, Saitama, Japan.

: To investigate predictors of acute kidney injury (AKI) following open aortic repair (OAR) requiring suprarenal clamping. : The study included 833 nonhemodialysis patients who had undergone elective OAR (with suprarenal clamping, n=73; with infrarenal clamping, n=760). We evaluated AKI as defined by the criteria of the Kidney Disease Improving Global Outcomes (KDIGO) and compared in-hospital outcomes between the two groups. We also investigated the effects of AKI on outcomes, factors related to post-suprarenal clamping AKI, and efficacy of hypothermic renal perfusion (HRP) in the suprarenal clamping group. : For the suprarenal vs. infrarenal clamping group, in-hospital mortality was 0% (0/73) vs. 0.5% (4/760). The incidence of AKI was greater in the suprarenal clamping group (37% vs. 15%, P<0.001), and the hospital stay for patients with AKI was longer than for those patients without AKI (median, 21 days vs. 16 days; P=0.005). Renal ischemia time and bleeding volume >1,000 mL were associated with post-suprarenal clamping AKI. Renal ischemia time was longer with HRP (n=15) than without HRP (n=58) (median, 51 min vs. 33 min; P=0.011), and HRP did not decrease the incidence of AKI (40% vs. 36%; P=0.78). : Prolonged renal ischemia and substantial intraoperative bleeding are associated with postoperative AKI following suprarenal clamping.
