a 46 year old man had been undergone aortic valve replacement (avr) due to mechanical aortic valve endocarditis two month ago. he was referred to imam khomeini hospital because of dyspnea since two weeks ago. echocardiography showed the false aneurysm, with an area of flow beyond the lumen of the aorta. this patient underwent reoperation, the previously implanted aortic valve was removed, metic...

There is a growing interest in minimally invasive access for aortic valve surgery. The upper hemi-sternotomy provides good aortic valve exposure, with numerous possible advantages. Nevertheless, some surgeons remain skeptical about limited access surgery because it is technically more demanding. Sutureless and rapid-deployment bioprostheses could alleviate these concerns by improving ease of im...

introduction: aortic valve sclerosisis considered as a manifestation of coronary atherosclerosis. recent studies demonstrated an association between aortic valve sclerosis and obstructive coronary artery disease. the purpose of this study was to evaluatethe correlation betweenaortic valve sclerosis andobstructive coronary artery disease and the extent of coronary artery disease in patients hosp...

Background EuroSCORE has been proposed to identify patients at high risk for surgical aortic valve replacement and estimate for them the risk-benefit of percutaneous implantation. However, it has been clearly demonstrated that this system overestimates mortality, particularly in the elderly population undergoing surgery for aortic valve replacement. An actualized model called EuroSCORE II has b...

INTRODUCTION The transcatheter aortic valve implantation in the treatment of high-risk symptomatic aortic stenosis has increased the number of implants every year. The learning curve for transcatheter aortic valve implantation has improved since the last 12 years, allowing access alternatives. OBJECTIVE The aim of this study is to approach the implantation of transcatheter aortic valve throug...

Aortic valve replacement in the setting of critical aortic valve stenosis with cardiogenic shock is associated with high mortality, yet surgery is the only definitive treatment. We present the case of a patient with critical aortic valve stenosis and cardiogenic shock who received a short period of percutaneous mechanical support and balloon aortic valvuloplasty that resulted in rapid clinical ...

Aortic valve disease is a fatal disease with but a single cure. Removal of the mechanical obstruction in aortic stenosis (surgery or TAVI) and replacement of an incompetent valve (so far only surgery) are the only treatment options. While aortic valve replacement in patients with isolated valve disease and normal pumpfunction of the heart has become a routine procedure and is performed with exc...

Sutureless aortic valve replacement (AVR) was developed as an alternative treatment option to conventional open-heart surgery and transcatheter aortic valve implantation for "gray zone" patients. The need for concurrent mitral valve surgery is generally viewed as a contraindication to sutureless AVR. The purpose of this brief paper is to report our experiences with sutureless valves in patients...

Sustained monomorphic ventricular tachycardia (VT) after valve surgery is uncommon. Cases of focal VT or bundle-branch re-entry after aortic valve surgery have been reported. We present the case of a 60 year-old patient with an incessant outflow tract VT early after aortic valve replacement. We suggest the disease process affecting the valve and adjacent area, and/or the surgical procedure,...

BACKGROUND Patients with Marfan syndrome are referred for cardiac surgery due to root aneurysm with or without aortic valve regurgitation. Because these patients are young and frequently present with normal-appearing aortic cusps, valve sparing is often recommended. However, due to the genetic nature of the disease, the durability of such surgery remains uncertain. METHODS Between February 20...
