Introduction: Observing microembolic signals in brain vessels by transcranial Doppler technology is a very common finding in patients with mechanical heart valve. These signals are almost always clinically asymptomatic. The aim of this study was assessment of transcranial Doppler in detecting probability of stroke in patients with mechanical heart valve. Methods: This descriptive study was ca...

Prosthetic valve re-operation has greater mortality and morbidity than primary valve replacement. By recognition of factors influencing on causes of redo operation and preoperative survival, one can select appropriate prosthesis at primary valve replacement and when operation performed at appropriate time, surgical risk can be reduced.Methods and Materials: Two hundred patients that underwent p...
patients underwent 262 valve replacements with frame-mounted autologous fascia lata valves in the aortic, mitral, and/or tricuspid positions at the National Heart Hospital. A single fascia lata valve was inserted in 146 patients and multi-valve replacement was performed in 55 instances. Hospital and late mortality are comparable with that following other procedures of heart valve replacement. O...
introduction tetralogy of fallot (tof) in the absent of pulmonary valve is a rare congenital anomaly (3%of tof patients). case presentation we are presenting an 18- year-old male with history of dyspnea on exertion and cyanosis since childhood. despite the diagnosis of congenital heart disease, no intervention was done due to his poor socioeconomic culture. at age of 18, he referred to our cent...
A 41-year-old African male presented with worsening dyspnea and cachexia concerning for congestive heart failure. Transesophageal echocardiogram revealed a large mass attached to the aortic valve leaflet, mass attached to the flail anterior mitral valve leaflet, severe pulmonary hypertension and dilatation of the aortic root along with fistula between the right coronary aortic cusp and the righ...
OPINION STATEMENT Heart valve disease is a major health burden, treated by either valve repair or valve replacement, depending on the affected valve. Nearly 300,000 valve replacements are performed worldwide per year. Valve replacement is lifesaving, but not without complications. The in situ tissue-engineered heart valve is a promising alternative to current treatments, but the translation of ...
OBJECTIVES The aim of this paper is to describe the feasibility of a novel transcatheter approach for mitral valve replacement using only venous access. BACKGROUND Failure of mitral valve prostheses necessitating reoperation can represent a high-risk clinical scenario. Although repeat cardiac surgery remains the standard of care for most failed mitral valve operations, nascent transcatheter o...
patients with valvular heart disease suffer from atrial fibrillation for more than 12 months after valve surgery and have a low probability of remaining in sinus rhythm. we performed an intra-operative procedure similar to surgical maze ііі procedure for conversion of this arrhythmia to sinus rhythm. we did this study to evaluate the efficacy of this procedure to restore the sinus rhythm in pat...
