Hybrid Repair of Infected Femoral Artery Pseudoaneurysm: Stent Graft Placement and Artificial Graft Replacement.

A femoral artery pseudoaneurysm is the most prevalent complication of femoral access due to the artery's accessibility and frequent use for catheterization and blood tests. An infected femoral artery pseudoaneurysm is often life-threatening and challenging to manage. A 70-year-old male with a history of tongue cancer treatments, including resection, lymph node dissection, and radiation chemotherapy, visited his previous physician for a fever and was prescribed oral antibiotics, but the fever persisted, accompanied by pain and a mass in the left groin.

Emergency Open Surgical Repair for Ruptured Abdominal Aortic Aneurysm in Octogenarians and Nonagenarians: A Single-Center Retrospective Observational Study.

Background: In the endovascular aneurysm repair era, open surgical repair (OSR) is performed for ruptured abdominal aorta aneurysm (RAAA) in patients with complex aneurysm neck and technical difficulties. Understanding the risk factors of OSR is essential for the clinical selection of the ideal surgical procedure. We aimed to re-evaluate the outcomes of OSR and treatment options for RAAA.

Pulmonary Tumor Thrombotic Microangiopathy Suspected to be COVID-19 Vaccine-Related Myocarditis: A Case Report.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a very rare condition that can lead to acute severe pulmonary hypertension and circulatory failure. It is caused by tumor cell microvascular obstruction and is usually difficult to diagnose; in fact, it is often diagnosed after death. We report the case of a patient who experienced a sudden cardiac arrest and developed severe pulmonary hypertension two days after receiving the coronavirus disease (COVID-19) vaccine.

Temporary Epicardial Pacing Wire Migration to the Pulmonary Artery in the Early Postoperative Stage.

Temporary epicardial pacing wires (TEPWs) are widely used during open heart surgery to treat postoperative bradycardia or arrhythmia. They are usually removed, but the wire is cut at the skin entrance site if there is resistance upon removal. Residual TEPWs have risks of complications such as infection, but they rarely migrate to distant organs.

Experiences in Emergency Cardiac Surgery of COVID-19-Positive Patients: A Case Series.

The coronavirus disease-2019 (COVID-19) pandemic has placed many restrictions on medical care. The timing of surgical treatment has been particularly affected, with patients experiencing delayed operation dates. This report describes three patients with preoperative COVID-19-positive diagnoses, tested with reverse transcription-polymerase chain reaction, who were urgently treated surgically with excellent results.

Utility of cardiac magnetic resonance imaging for pre-operatively evaluating the degree of caseous calcification of the mitral annulus infiltration within the left ventricular myocardium: a case report.

Background: Depending on the degree of infiltration of dry mitral annulus calcification (MAC) into the left ventricular myocardium, calcification removal may cause thinning of the left ventricular wall and increase the risk of post-operative left ventricular rupture. Therefore, the degree of pre-operative infiltration into the left ventricular myocardium should be assessed as accurately as possible. We report a case of caseous calcification of the mitral annulus (CCMA), a subtype of MAC, in an 84-year-old woman; cardiac magnetic resonance imaging (MRI) was useful in assessing the degree of left ventricular infiltration of calcification.

Effect of waiting time for COVID-19 screening on postoperative outcomes of type A aortic dissection: An institutional study.

Background: Since November 2020, all patients undergoing emergency surgery at our hospital have been subjected to preoperative reverse transcription polymerase chain reaction (RT-PCR) screening to prevent nosocomial COVID-19 infection, with admission to the operating room requiring a negative result. Herein, we compared the pre- and postoperative outcomes of acute type A aortic dissection surgery before and after implementing the RT-PCR screening for all patients.

Methods: We compared the postoperative results of 105 patients who underwent acute type A aortic dissection emergency surgery from January 2019 to October 2020 (Group I) and 109 patients who underwent the surgery following RT-PCR screening from November 2020 to March 2022 (Group II).

A rare case of asymptomatic right coronary artery ectasia associated with giant aneurysm.

A rare case of giant coronary artery ectasia associated with coronary artery aneurysm was recognized. A 69-year-old woman presented with an ischemic electrocardiogram changes during a medical check-up. Coronary computed tomography angiography showed right coronary artery (RCA) ectasia associated with a giant aneurysm originating from the distal RCA.

Early mortality of emergency surgery for acute type A aortic dissection in octogenarians and nonagenarians: A multi-center retrospective study.

Objectives: The clinical data on postoperative mortality and central nervous system (CNS) complications in older adults who underwent acute type A aortic dissection are limited. Thus, in this study we aimed to evaluate the association between age and early postoperative mortality and occurrence of CNS complications.

Methods: This multicentric retrospective cohort study included 5 tertiary hospitals in Japan.

[Four Times Aortic Valve Replacement for Recurrent Aortic Annulus Destruction Due to Behçet's Disease:Report of a Case].

Surgical results of aortic regurgitation with Behcet's aortitis is associated with high morbidity and mortality due to risk of annular dehiscence. Here we describe a case of severe aortic regurgitation with Behcet's disease in 51-year-old man who underwent aortic valve replacement and subannular patch reconstruction for suspected infectious endocarditis with severe aortic regurgitation and subannular abcess. Then we performed three times aortic valve replacement for recurrent prosthetic valve dehiscence.

Hybrid treatment of a giant coronary artery aneurysm in a patient with immunoglobulin G4-related disease.

A 62-year-old man was diagnosed with a giant coronary artery aneurysm associated with immunoglobulin G4 (IgG4)-related disease. He had previously undergone two thoracic operations with sternotomies and abdominal aortic aneurysm repair for IgG4-related aortopathy. We opted for hybrid open and endovascular repair to reduce risk and avoid complications of a resternotomy and extracorporeal circulation.

Post-myocardial infarction left ventricular septal dissecting aneurysm: a case report.

Background: Post-infarction perforation of the ventricular septum is recognized as a major complication of post-myocardial infarction. However, post-infarction ventricle dissection is seldom reported, as the ventricular shunt often accompanying this condition is a significant cause of cardiogenic shock. We encountered a rare case of ventricular dissection unaccompanied by a shunt, which caused a state of shock.

[Successful Use of Percutaneous Left Ventricular Assist Device( Impella) and Veno Artery Extracorporeal Membrane Oxygenation( VA-ECMO) for Ischemic Cardiogenic Shock;Report of a Case].

A 73-year-old male was referred to our hospital for acute congestive heart failure. His cardiac and respiratory conditions were worsening with cardiogenic shock requiring intubation. Coronary angiography revealed severe triple vessel disease, and echocardiography showed severe left ventricular dysfunction.

Dimerized glycosaminoglycan chains increase FGF signaling during zebrafish development.

Proteoglycans (PGs) modulate numerous signaling pathways during development through binding of their glycosaminoglycan (GAG) side chains to various signaling molecules, including fibroblast growth factors (FGFs). A majority of PGs possess two or more GAG side chains, suggesting that GAG multivalency is imperative for biological functions in vivo. However, only a few studies have examined the biological significance of GAG multivalency.

[Ruptured thoracic aortic aneurysm complicated by acute aortic dissection and aortic valve regurgitation; report of a case].

An 87-year-old man was found loss of consciousness after falling. He was found in a state of shock. Computed tomography showed rupture of aneurysm of the ascending aorta and aortic arch with acute aortic dissection.

[Mobile mass in the descending aorta with multiple embolism].

A 46-year-old man was referred to our hospital for abdominal pain. Computed tomography (CT) revealed mobile mass in the descending aorta and multiple systemic embolism. Emergent operation was indicated.

Cardiogenic shock without cardiac tamponade caused by a subepicardial hematoma after percutaneous coronary intervention.

A 73-year-old man complaining of pain on effort was admitted to a hospital for a percutaneous coronary intervention (PCI) because of severe stenosis of the mid right coronary artery. During PCI, a coronary artery was ruptured, and the patient suddenly went into shock. Percutaneous pericardiocentesis was successfully performed, and cardiac tamponade was relieved.

[Cylindrical patch repair for circumferential subvalvular abscess due to prosthetic valve endocarditis].

A 51-year-old male underwent aortic valve replacement and vascular prosthesis implantation due to an aneurysm of the ascending aorta combined with aortic regurgitation caused by the bicuspid aortic valve. Semi-emergency surgery was performed due to severe paravalvular leakage with prosthetic valve endocarditis 16 months after the 1st operation. The circumferential annular abscess cavities were closed with a cylindrical patch, and a mechanical valve was installed on the upper edge of the sutured cylindrical patch.

Ventricular septal perforation caused by right-sided infective endocarditis associated with giant vegetation.

A 71-year-old man presented with general fatigue associated with syncope and fever, and was admitted to our hospital and treated with antibiotics for pneumonia. On day 10 after admission, cardiac echocardiography showed a ventricular septal perforation and giant vegetation floating in the right ventricle near the tricuspid valve, which had not been detected at the time of admission. An emergency operation (including vegetation excision, debridement, ventricular septal perforation patch closure, and tricuspid valve replacement) was performed.
