Simultaneous gastroepiploic artery to right coronary artery bypass and trans-catheter aortic valve implantation: case series.

Patients with coronary artery disease undergoing trans-catheter aortic valve implantation (TAVI) often receive TAVI alone. However, in cases of severe coronary lesions or anticipated difficulty in coronary access post-TAVI, percutaneous coronary intervention or coronary artery bypass grafting may be necessary. We performed simultaneous gastroepiploic artery to posterior descending artery bypass and TAVI in two patients with severe calcification of the right coronary artery ostium which is unsuitable for percutaneous intervention.

Risk factors for unsuccessful restoration of coronary flow reserve after coronary bypass surgery.

Objectives: Coronary flow reserve (CFR) is a strong predictor of cardiovascular events and prognosis in patients with coronary artery disease. This study aimed to evaluate preoperative factors associated with the unsuccessful restoration of CFR after coronary artery bypass grafting (CABG).

Methods: Included in this study were the 65 patients who presented with functionally significant left anterior descending artery (LAD) lesions confirmed by both fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR), and who underwent successful CABG at our hospital within the study period.

Bilateral Axillary Artery Perfusion in Total Arch Replacement.

Background: The site of arterial cannulation is an important consideration in the prevention of cerebral infarction after total arch replacement. We compared the outcomes of cannulation of the bilateral axillary artery, the femoral artery, and central cannulation in total arch replacement.

Methods: Enrolled were 242 patients, categorized into three groups according to the arterial cannulation site used: bilateral axillary artery group, 124 patients; femoral artery group, 88 patients; central cannulation group, 30 patients.

Simultaneous hybrid off-pump coronary artery bypass grafting and transcatheter aortic valve implantation in elderly patients.

Purpose: Optimal strategy for transcatheter aortic valve implantation (TAVI) in patients with coronary artery disease (CAD) is unresolved. We evaluated the surgical outcomes of hybrid coronary artery bypass grafting (CABG) and TAVI in elderly patients.

Methods: We retrospectively evaluated patients who underwent simultaneous TAVI and CABG at Wakayama Medical University, Japan.

Impact of Graft Velocity on Saphenous Vein Graft Atherosclerosis after Coronary Artery Bypass Grafting.

Purpose: Saphenous vein grafts (SVGs) sometimes occur as vein graft stenosis or failure in coronary artery bypass grafting. The purpose of this study was to detect the factors affecting vein graft atherosclerosis.

Methods: We performed two analysis.

The impact of a preoperative nurse-led orientation program on postoperative delirium after cardiovascular surgery: a retrospective single-center observational study.

Background: Postoperative delirium in intensive care is common and associated with mortality, cognitive impairment, prolonged hospital stays and high costs. We evaluate whether a nurse-led orientation program could reduce the incidence of delirium in the intensive care unit after cardiovascular surgery.

Methods: In this retrospective cohort study, we enrolled patients admitted to the intensive care unit for planned cardiovascular surgery between January 2020 and December 2021.

Four-year outcome of the tricuspid valve leaflet augmentation and ring annuloplasty in dextrocardia.

Unlabelled: A 62-year-old male was admitted to our hospital with worsening dyspnea. Chest X-ray revealed dextrocardia, and echocardiography revealed decreased right ventricular function, a severely dilated tricuspid annulus, a massive tricuspid, and trivial mitral regurgitation. Patch augmentation of the tricuspid leaflet with auto-pericardium and ring annuloplasty with a flat-type upside-down artificial ring to fit the dextrocardia heart was performed.

Calcified thrombi of the Valsalva sinuses mimicking an aortic valve tumour.

Tumours or tumour-like lesions around the aortic valve are relatively rare and are difficult to diagnose. We report an interesting case of calcified thrombi in the Valsalva sinuses and coronary cusps that mimicked an aortic valve tumour. A 68-year-old man presented with a 20-mm calcified mass in the non-coronary and left-coronary cusps extending to their corresponding Valsalva sinuses, which was detected by echocardiography and contrast-enhanced computed tomography.

[Total Arch Replacement Using Bilateral Axillary Artery Perfusion].

Objectives: The selection of arterial cannulation site is an important decision to avoid cerebral complication for total arch replacement(TAR). We report the surgical outcome of TAR using bilateral axillary artery perfusion in our hospital.

Methods: Between January 2012 and June 2020, 97 patients who underwent elective TAR for atherosclerotic aneurysms were enrolled in this study.

Adventitial cystic disease of the femoral vein accompanied by deep vein thrombosis.

Adventitial cystic disease of the femoral vein is an extremely rare condition; therefore, diagnosis, treatments, surgical approaches and long-term prognosis are not well defined. We report the case of a 67-year-old man with femoral vein adventitial cystic disease complicated with deep vein thrombosis. He presented with right leg oedema.

Functional assessment of improvement of myocardial ischemia using coronary flow velocity reserve after coronary artery bypass surgery in hemodialysis.

Background: In patients with end-stage renal disease requiring hemodialysis (HD patients), myocardial ischemia after coronary artery disease is a major cause of mortality. Coronary pathophysiology, namely myocardial microvascular dysfunction, appears to differ from patients not requiring HD (non-HD patients).

Objectives: We compared functional improvement of myocardial ischemia after coronary artery bypass surgery (CABG) between HD and non-HD patients by transthoracic coronary flow velocity reserve (CFVR).

A clampless anastomosis technique using the aortic cannula mounted by a prosthetic graft for a severely calcified aorta in a patient with subclavian steal syndrome.

Patients with severely calcified aorta are at high risk of embolic stroke during surgery and it is not feasible to clamp the aorta, necessitating alternative surgical strategies. We present a clampless anastomosis technique using the aortic cannula mounted by a prosthetic graft for a severely calcified aorta in a patient with subclavian-vertebral artery steal syndrome.

Functional Evaluation of the Myocardial Ischemia After Coronary Artery Bypass Surgery Using Coronary Flow Velocity Reserve in Left Ventricular Hypertrophy.

Patients with left ventricular hypertrophy (LVH) have reportedly higher than normal mortality and incidences of cardiovascular events. Coronary microvascular pathophysiology also appears to differ from other populations. Such coronary microcirculation dysfunctions are considered strong causes of cardiac events.

Repair of an adult aorto-pulmonary artery fistula associated with a ruptured aortic arch aneurysm using a frozen elephant trunk technique.

We describe the repair of an acute aorto-pulmonary artery fistula in a 82-year-old patient with a ruptured aortic arch aneurysm using a frozen elephant trunk technique.

Aortic valve replacement with essential thrombocythemia.

Cardiac surgery in patients with essential thrombocythemia carries the risks of both thrombotic events and a bleeding tendency. We report the case of a 75-year-old man with essential thrombocythemia who underwent successful surgical aortic valve replacement after his platelet count was controlled with plateletpheresis 3 times before surgery.

Congenital mitral regurgitation with Down syndrome.

A 19-year-old man with Down syndrome had congenital mitral regurgitation. He had slight mental retardation and difficulty in performing independent oral drug administration. We planned mitral valve plasty to avoid postoperative anticoagulant therapy.

[A case of gastric cancer with peritoneal dissemination and massive ascites successfully treated with S-1/docetaxel therapy].

A 49-year-old woman who complained of abdominal bloating and numbness in the bilateral lower limbs was diagnosed as advanced scirrhous gastric cancer with massive ascites. The biopsy specimen showed a poorly-differentiated adenocarcinoma. She was therefore treated with combined chemotherapy of tri-weekly docetaxel(40mg/m2, day 1, 22)and S-1(60mg/m2, day 1-14 with 1-week rest)for unresectable gastric cancer.
