Introduction And Importance: The coexistence of central venous occlusion and arteriovenous fistulas (AVF) is rare among non-dialysis patients. Herein, we describe a case of left brachiocephalic venous occlusion with spontaneous AVF, presenting with severe edema in left upper extremity and face.

Case Presentation: A 90-year-old woman presented to our hospital with gradually worsening edema in her left arm and face for eight years.

Background: Open thoracic surgery (with infected lesion removal, prosthetic graft replacement, and pedicled tissue flap) has remained the main treatment for infected thoracic aortic aneurysms to date. Recent reports have highlighted good prognostic outcomes with thoracic endovascular aortic repair. However, thoracic endovascular aortic repair for infected thoracic aortic aneurysms is associated with an exacerbation of infection due to residual infected tissues.

Situs inversus totalis (SIT) with dextrocardia is a rare autosomal recessive disorder. We herein describe a blunt thoracic aortic injury (BTAI) in a patient with SIT and dextrocardia. An 18-year-old girl who was injured by a fall presented to our hospital.

Introduction: Celiac artery (CA) dissection due to blunt abdominal trauma is extremely rare and, as such, the clinical features of this potentially life-threatening injury have not been clearly defined, nor have treatment strategies been established.

Presentation Of Case: We describe the case of a 61-year-old man who presented to our emergency department after a motor vehicle accident. Although the patient did not report abdominal pain, enhanced computed tomography (CT) revealed CA dissection.

Coronary artery embolism due to BioGlue surgical adhesive after repair of type A acute aortic dissection is a rare condition. We report a case of BioGlue coronary artery embolism after type A acute aortic dissection repair confirmed using intravascular ultrasound imaging and pathological examination. It was successfully treated with percutaneous coronary intervention.

A 60-year-old woman with cardiac sarcoidosis developed recurrent and refractory right heart failure 26 months after tricuspid valve replacement. Echocardiography revealed thickened and immobile cusp with increased diastolic tricuspid gradient of 8-10 mmHg, consistent with bioprosthetic tricuspid stenosis (TS). Prolonged intravenous injection of dobutamine and carperitide, with intermittent intravenous furosemide, was necessary at multiple times.

Unilateral pulmonary edema (UPE) is a rare entity and is usually associated with severe mitral regurgitation and more frequently occurs in the right lung. We herein report a case of unilateral left pulmonary edema caused by external compression of the right pulmonary artery and left pulmonary vein caused by the presence of hematoma due to type A acute aortic dissection (AAD), resulting in asymmetrically increased inflow and decreased outflow in the left pulmonary circulation. Physicians caring for patients with UPE should be aware that AAD leading to the external compression of the heart may be a possible underlying mechanism.

We herein report 3 cases of acute aortic dissection (AAD) in which the initial 12-lead electrocardiogram showed typical ST elevation consistent with acute pericarditis. All patients exhibited small pericardial effusion but did not suffer from rupture into the pericardium or clinical tamponade. Slow leakage or exudate stemming from the dissecting hematoma appeared to have caused inflammation, resulting in pericarditis.

We describe a rare complication, transverse colon herniation into the mediastinum, after the use of an omental flap. Adequate separation of the transverse colon from the omental flap and ensuring that the incision in the diaphragm is as small as possible are important preventive measures.

Background: Aorto-cavitary fistula is a rare condition, and the most common underlying aetiology is infective endocarditis (IE) of the native or the prosthetic aortic valve. We report a case of aorto-right inferior pulmonary venous fistula following redo mitral valve replacement (MVR) for prosthetic mitral valve IE.

Case Summary: A 74-year-old woman underwent urgent redo MVR for prosthetic mitral valve IE.

Background: Bioprosthetic tricuspid valve stenosis is a late sequela of tricuspid valve replacement (TVR); however, detailed information regarding its clinical picture is lacking.

Case Summary: Thirty-one patients with bioprosthetic TVR (mean age: 60.5 ± 16.

To report 3 patients with infective endocarditis who underwent transcatheter arterial embolization for mycotic aneurysm of the distal superior mesenteric artery (SMA). Three men (60, 64, and 65 years old) were diagnosed with infective endocarditis. Antibiotics were initiated immediately after admission and continued for several weeks to months.

Purpose: To evaluate the efficacy of percutaneous transluminal angioplasty for early failing hemodialysis arteriovenous fistulas (AVFs) and predictors of secondary functional patency (FP).

Methods: A review of our endovascular registry database showed that 61 patients with early failure after a surgically created AVF underwent endovascular intervention between 2011 and 2016. Median time from AVF creation to first intervention was 5.

Background: Gastroepiploic artery aneurysms (GEAAs) are extremely rare. Ruptured GEAAs are related to high mortality and often treated by open surgery. We describe a case of a ruptured right GEAA that was successfully treated by transcatheter arterial embolization (TAE).

Background: Primary aortoduodenal fistula (PADF) is an abnormal connection between the aorta and the duodenum and is a life-threatening condition. It is a very rare cause of gastrointestinal bleeding, which often leads to delay in its diagnosis. Prompt diagnosis and surgical treatment are crucial to improve the outcome of patients with PADF.

Libman-Sacks endocarditis is a relatively rare sterile verrucous vegetative lesion observed in systemic lupus erythematosus (SLE)/antiphospholipid syndrome (APLS) patients. Most patients with this condition are asymptomatic. Here we report a case of a 46-year-old woman with APLS secondary to SLE complicated with frequent thromboembolic events due to a mitral valve mass.

A 69-year-old man with situs inversus, levocardia and inverted great arteries developed severe dynamic left ventricular outflow tract (LVOT) obstruction with systolic anterior motion of the anterior mitral leaflet. There was no asymmetric septal hypertrophy. A possible mechanism of the LOVT obstruction in the present case may have been related to an abnormally long and bent outflow tract resulting from overriding of the right ventricle over the LVOT due to a congenital malposition of the heart.

Background: Initial diagnosis of acute aortic dissection (AAD) in the emergency room (ER) is sometimes difficult or delayed. The aim of this study is to define clinical predictors related to inappropriate or delayed diagnosis of Stanford type A AAD.

Methods: We conducted a retrospective analysis of 127 consecutive patients with type A AAD who presented to the ER within 12 h of symptom onset (age: 69.

We report a case of infective endocarditis complicated with left ventricular pseudoaneurysm originating from the posterior annulus of the prosthetic mitral valve in a 56-year-old woman. Despite prolonged antibiotic treatment, transesophageal echocardiography (TEE) showed partial detachment of the prosthesis from the posterior mitral annulus. Three-dimensional rotational computed tomography clearly demonstrated a pseudoaneurysm toward the posterolateral portion of the mitral prosthetic valve, which was not evident by TEE.

Background: Not only symptoms but electrocardiographic (ECG) changes mimicking acute coronary syndrome as well have been known to develop in acute aortic dissection (AAD). However, detailed information is lacking.

Objective: We sought to evaluate incidence, patterns, and underlying mechanisms for acute ECG changes in type A AAD.
