Over 56,000 aortic valves are replaced annually in the United States, making AS the second most common reason for heart surgery, behind only coronary artery disease. The intraoperative echocardiographer plays a part in confirming the diagnosis of AS, quantifying its severity, and ensuring proper prosthetic valve function postoperatively. However, the aortic valve is only one component of the ao...

BACKGROUND The problem of prosthetic heart valve selection in fertile women with acquired heart defects remains crucial in modern cardiology. Mechanical heart valves require lifelong indirect anticoagulant therapy, which has significant fetal toxicity and is unacceptable for women planning pregnancy. Bioprosthetic heart valves are the best choice for fertile women; however, their durability is ...

The most important causes of acute collapse in pregnancy are pulmonary embolism, amniotic fluid embolism, acute coronary syndrome, thrombosed mechanical prosthetic heart valves, acute aortic dissection, cerebrovascular incidents and anaesthetic complications like failed intubation, anaphylaxis, and problems relating to regional or local anaesthetic agents. The management is based on supporting ...

A 10-year-old girl with trisomy 21 and complex congenital heart disease presented with acute lymphoblastic leukemia. Her chemotherapy required modifications due to poor baseline cardiac status and a mechanical prosthetic heart valve that was dependent on anticoagulation. We describe our management including the use of low-molecular-weight heparin as anticoagulation for a mechanical heart valve,...

  Background: Embolus is one of the causes of ischemic stroke that can be due to cardiac sources such as valvular heart diseases and atrial fibrillation and atheroma of the aorta. Transesophageal echocardiography (TEE) is superior in identifying potential cardiac sources of emboli. Due to insufficient data on TEE findings in ischemic stroke in Iran, the present study was done to evaluate TEE in...

The patient was a 29-year-old woman who, when she was an 8-year-old, had undergone atrial septal defect (ASD) closure and mitral valve replacement (MVR) using a Björk-Shiley valve (25 mm) for Lutembacher syndrome. Because of a planned pregnancy, warfarin had been replaced by heparin. During the 7th week of pregnancy, she was admitted to our hospital because of dyspnea. She was diagnosed with ac...
