Mid-term results of mitral valve reconstruction with autologous pericardial patch for active infective endocarditis with extensive leaflet destruction.

Objectives: This study aimed to evaluate the outcomes of our repair technique using autologous pericardial patches for active infective endocarditis with extensive mitral valve destruction.

Methods: From 2009 through 2016, 12 patients with extensive mitral leaflet destruction due to infective endocarditis underwent mitral valve repair with an autologous pericardial patch. Mid-term clinical outcomes and echocardiographic findings of these patients were retrospectively assessed.

One-Stage Hybrid Total Aortic Arch and Descending Thoracic Aortic Repair is a Safe and Secure Procedure With Less Postoperative Complications for Extended Aortic Arch Aneurysms.

Purpose: Hybrid aortic arch repair (HAR) has been implemented for extended aortic arch and descending thoracic aortic disease since 2012 in our institution. This study aimed to estimate the early and mid-term efficacy and safety of HAR.

Materials And Methods: From 2007 to 2019, 56 patients underwent HAR for extended aortic arch disease, and 75 patients underwent total arch replacement (TAR) for arch-limited disease.

Management of Right Gastroepiploic Arterial Coronary Grafts in Subsequent Abdominal Surgeries.

Background: The right gastroepiploic artery (GEA) is utilized as an excellent in situ arterial graft conduit to right coronary artery territory for coronary artery bypass grafting (CABG). However, there remain great concerns regarding the management of patients with a patent in situ GEA during abdominal surgery following CABG.

Methods: From 1995 to 2016, GEA was used for CABG in 278 patients at our institution.

Excision of thoracic vertebral chondrosarcoma after spinal decompression.

A 44-year-old man presented with an abnormal chest shadow. Computed tomography-guided biopsy showed a chondral tumor of the thoracic vertebrae. Five years later, he developed a walking disorder, left leg numbness, and a vesicorectal disorder.

Antineutrophil Cytoplasmic Antibody-Associated Multiple Giant Saccular Aortic Aneurysms.

We describe a very rare case of a 67-year-old man with multiple saccular aortic aneurysms throughout the entire aorta due to antineutrophil cytoplasmic antibody-associated vasculitis (AAV). The patient underwent staged aortic surgical procedures, including stent-graft insertion for a left iliac artery aneurysm, thoracic endovascular aortic repair for a descending aortic aneurysm, and total replacement of the ascending aorta and aortic arch with the use of high-dose steroids to control inflammation. The histologic findings demonstrated that the damage to the vasa vasorum of the adventitia resulting from AAV caused ischemia of the media, resulting in the formation of saccular aneurysmal changes.

Minimally Circulatory-Assisted On-Pump Beating Coronary Artery Bypass Grafting for Patients With Complex Conditions for Off-Pump Surgery.

Off-pump coronary artery bypass grafting (OPCAB) in patients with acute myocardial infarction (AMI) is difficult because of circulatory deterioration during displacement of the heart. At our institution, we performed minimally circulatory-assisted on-pump beating coronary artery bypass grafting (MICAB) in these patients. During MICAB, support flow was controlled at a minimal level to maintain a systemic blood pressure of approximately 100 mm Hg and a pulmonary arterial systolic pressure of <30 mm Hg, providing optimal pulsatile circulation for end-organ perfusion and prevention of heart congestion.

Easy and Safe Total Debranching of Arch Aneurysms Using Axilloaxillary Arterial Bypass.

Techniques used in hybrid repair of proximal aortic arch diseases are associated with perioperative complications such as cerebrovascular emboli. We present an easy and safe technique of total debranching thoracic endovascular aortic repair for arch diseases using axilloaxillary arterial bypass. The placement of the axilloaxillary arterial bypass enables perfusion of the brachiocephalic artery even when the artery is clamped.

Influence of procedural differences on mitral valve configuration after surgical repair for functional mitral regurgitation: in which direction should the papillary muscle be relocated?

Background: After restrictive mitral annuloplasty (RMAP) for functional mitral regurgitation (MR), the MR frequently recurs. Papillary muscle relocation (PMR) should reduce the recurrence rate. We assessed the influence of procedural differences in PMR on the postoperative mitral valve configuration.

Proposal of a novel index for selection of optimal annuloplasty ring size for tricuspid annuloplication.

Background: Optimal ring size in tricuspid annuloplasty (TAP) surgery to treat functional tricuspid regurgitation (TR) was investigated because optimal ring size remains undefined.

Methods And Results: Sixty seven patients who underwent TAP at our institution were retrospectively studied. Tricuspid Annuloplasty Ring size Index (TARI) was defined as implanted tricuspid annuloplasty ring size divided by body surface area (BSA).

Atherosclerotic pseudoaneurysm of the left subclavian artery: a case report.

A subclavian artery aneurysm is rare. We report the case of a 61-year-old man with a history of hypertension and angina pectoris who was diagnosed with an atherosclerotic aneurysm of the left subclavian artery. An incidental computed tomography scan revealed a 37-mm saccular aneurysm adjacent to both the proximal left subclavian artery and the distal aortic arch.

The roles of natriuretic peptides in pericardial fluid in patients with heart failure.

Background: It is well known that the plasma concentrations of atrial and brain natriuretic peptides, as cardiac hormones, are elevated in heart failure.

Hypothesis: Pericardial fluid in patients with various heart diseases contains both natriuretic peptides that are released into the pericardial fluid. However, it is unknown whether these peptides reflect cardiac function in patients with various heart diseases, more than both the peptides in blood.

[Proximal anastomotic pseudoaneurysm due to gelatin-resorcin-formalin (GRF) glue after replacement of ascending aorta for acute aortic dissection; report of a case].

A 78-year-old man had previously undergone replacement of ascending aorta using gelatin-resorcin-formalin (GRF) glue for acute aortic dissection. Five years later, a follow-up computed tomography (CT) showed an aortic root pseudoaneurysm. Ultrasound cardiography revealed moderate aortic regurgitation and pseudoaneurysm of aortic root.
