Background: Pulmonary endarterectomy (PEA) for chronic thromboembolic pulmonary hypertension (CTEPH) is technically demanding. We tried to identify the predictors for short- and long-term outcomes after PEA for CTEPH with aggressive use of pulmonary vasodilators, including epoprostenol sodium.
Methods: From 2005 to 2013, 122 CTEPH patients, whose preoperative mean pulmonary artery pressure (mPAP) was 47 ± 10 mm Hg and pulmonary vascular resistance was 847 ± 373 dynes/s/cm, underwent PEA with hypothermic circulatory arrest.

However, few studies have compared the effectiveness of FET technique, in terms of the downstream aortic remodeling. Between 2005 and 2017, 50 patients underwent total arch replacement for Stanford type A aortic dissection, including that with (n = 22) and without FET technique (n = 28).

Methods: We present the clinical course of a 43-year-old woman in remission from diffuse large B-cell lymphoma after the chemotherapy including anthracyclines, who presented in cardiogenic shock 8 months after the end of chemotherapy.
We report a rare case of retrograde Stanford type A aortic dissection after endovascular repair for complicated Stanford type B aortic dissection. A 45-year-old man presented with a sudden onset of back pain and was transferred to our hospital. Computed tomography demonstrated acute Stanford type B aortic dissection with lower limb ischemia.

We experienced a rare case of recurrence of aneurysm of the ascending aorta 7 years after patch repair of a small aneurysm at an aortic cannulation site. The repaired aorta had been wrapped with a Teflon felt strip during the previous surgery, and the wrapped aorta had become thin with deterioration of the normal structure of the aortic wall.

Methods and results: From 2005 to 2015, 158 patients underwent surgical repair for AAD via a median sternotomy. We compared 24 (15.
Background: Pulmonary endarterectomy (PEA) has been the most effective therapy for chronic thromboembolic pulmonary hypertension (CTEPH). However, residual or recurrent pulmonary hypertension often persists after PEA. Recently, catheter-based angioplasty, called percutaneous transluminal pulmonary angioplasty (PTPA) or balloon pulmonary angioplasty, has been developed as a promising strategy for CTEPH.

Objectives: Cardiovascular manifestations determine the prognosis and survival of patients with Marfan syndrome (MFS). We assessed the early and mid-term outcomes of cardiovascular surgery for this patient population.
Patients And Methods: We conducted a retrospective evaluation of patients with MFS who underwent surgery in our department.
Background: To evaluate the prognosis after pulmonary thromboendarterectomy (PTE) in patients with chronic thromboembolic pulmonary hypertension (CTEPH), a lung biopsy was performed in 34 patients with central CTEPH and in 7 patients with peripheral CTEPH during PTE.
Methods And Results: Postoperative prognosis was classified from A to E based on the postoperative hemodynamic parameters and clinical condition, and was compared with the index of occlusion (IOCTEPH), which indicates the degree of occlusion in the small pulmonary arteries. Criteria of (A-E) were established only for central CTEPH.
We reviewed the results of thromboembolectomy, which was performed for the treatment of chronic thromboembolic pulmonary hypertension (CTEPH), 1 year after the operation. We obtained hemodynamic and respiratory data of 60 patients from the 112 patients who were operated at our institute. The hemodynamic parameters such as mean pulmonary arterial pressure (PAP), pulmonary vascular resistance (PVR), and cardiac index (CI) were significantly improved after the operation, and this improvement of pulmonary hemodynamics persisted even a year after the operation.

Echocardiography revealed prosthetic valve failure with a high-pressure gradient and small effective orifice area. The Starr-Edwards ball valves were successfully replaced with bileaflet mechanical valves.

Our current study aimed to evaluate the incidence of septic cerebral lesions in active IE patients by performing preoperative magnetic resonance imaging (MRI) including T(2)*- weighted sequences and magnetic resonance angiography (MRA) before urgent valve surgery, and to investigate whether such preoperative evaluation affects postoperative outcomes.
Methods: Eighteen patients were referred to our department for native valve IE during 2006-2010.

Pseudoaneurysm of the ascending aorta after cardiac surgery is a rare but life threatening complication, which can result in rupture. Pseudoaneurysms are usually related to the aortic cannulation, the proximal site of graft anastomosis, or the suture line of aortotomy, and often occur after mediastinal infection. We report a case of pseudoaneurysm of the ascending aorta associated with aortic cannulation and the proximal anastomosis of a saphenous vein graft without an obvious history of mediastinal infection.

Cardiac surgical procedure and catheter intervention of the aorta or its major branches have a potential risk for iatrogenic aortic dissection. This case demonstrates an iatrogenic type A aortic dissection after the elective balloon angioplasty for severe stenosis of the left subclavian artery orifice. The dissection retrospectively extended to the ascending aorta, and intramural hematoma was observed in the false lumen of the aorta.

Recently, we used a novel surgical technique involving left axillary perfusion to analyze the results of our surgical strategy and compare them with those reported in the literature.
Materials And Methods: Between August 2004 and July 2009, 39 patients underwent graft replacement for chronic type B aortic dissection.
This report presents an extremely rare case of paraplegia following emergency surgery for a nonruptured symptomatic abdominal aortic aneurysm. A 62-year-old man underwent an emergency surgical repair for a symptomatic nonruptured infrarenal abdominal aortic aneurysm. On postoperative day 2 paraplegia following spinal cord ischemia occurred at the T8 level.

After irradiation, the fragments mutated into high-molecular-weight (100-800 kbp) DNA fragments and then into ladder-formed internucleosomal DNA fragments. Poly-ADP-ribose polymerase (PARP) activity and NAD levels were reduced during DNA fragmentation.
