A 79-year-old man underwent 1-debranched thoracic endovascular aortic repair (TEVAR) for a saccular aneurysm of the distal arch of the aorta. Computed tomography performed 3 years after surgery revealed a significant displacement of the distal side of the stent graft and severe deformity due to displacement of the aorta. There were no obvious findings after aortic dissection.

A 66-year-old man. He had myocardial infarction due to occlusion of the left anterior descending branch, which was subsequently complicated by ventricular septal perforation. Ventricular septal perforation was repaired through right ventricle incision, applying double patches for closure, and injecting glue between the patches.

Article Synopsis
  • - The study discusses an innovative approach for closing an atrial septal defect in an adult with a rare condition known as infra-hepatic interruption of the inferior vena cava, which affects blood flow.
  • - The surgical team utilized a special venous cannulation technique, adding a cannula that drains the hepatic vein while using bicaval cannulations through the femoral and internal jugular veins for better management of blood flow during the operation.
  • - Preoperative imaging was crucial to assess the continuity of the inferior vena cava, helping plan the surgery and ensuring a clear working area in the right atrium during the procedure.

We report a rare case of right heart failure caused by distal aortic aneurysm. Although aortopulmonary fistula is a common complication of giant aortic arch aneurysm, right heart failure caused by mechanical pressure by aneurysm is very rare. A 79-year-old female patient presented dyspnea.

A 77-year-old man with a history of stent implantation in the right common iliac artery(CIA) and the left external iliac artery(EIA) was admitted to our hospital for a rapid growth of an aneurysm( max 53 mm) at Th11 level of the descending aorta. Although thoracic endovascular aortic repair (TEVAR) was required, there were many problems about access rout. The infrarenal abdominal aorta and the left EIA were severely calcified, and the lumens of the right CIA stent(5.

A 64-years-old man had cor triatriatum (Lucas-Schmidt type I A) with severe mitral regurgitation and atrial fibrillation. We perfomed resection of the anomalous septum between the accessory chamber and left atrium, and conducted mitral annuloplasty and maze procedure. Arrhythmia were not encountered after surgery.

The operative procedure of extensive aortic aneurysm with ischemic coronary artery disease is controversial. We report a case of arch and descending thoracic aortic aneurysm replacement with coronary artery bypass grafting(CABG)via left thoracotomy. A 70-year-old man followed up by hepatic disease was diagnosed with expanding aortic thoracic aneurysm at the other hospital.

Article Synopsis
  • The case discusses a rare occurrence of papillary muscle rupture following an acute myocardial infarction (AMI) in a 75-year-old man who experienced cardiac failure after a prior treatment for AMI.* -
  • The patient underwent mitral valve repair using artificial chordae to address the rupture, as well as a ring annuloplasty for stabilization.* -
  • Post-surgery, the patient's mitral regurgitation was effectively managed, and he was discharged without complications 25 days later.*
