Proper education and notification of patients undergoing heart valve replacement is of paramount importance. The past decade has witnessed a growing interest in the use of modern, advanced technologies in medicine and patient education. This study aimed to introduce an education-notification application for patients undergoing heart valve replacement. Research was carried out in two phases of s...

background: recent interests have mainly focused on the roles of serum calcium and phosphorus and their product (ca-p product) in the development of valvular heart disease. the present study assessed the relationship between the ca-p product and the severity of valvular heart disease in end-stage renal disease (esrd) patients undergoing chronic hemodialysis. methods: this cross-sectional study ...

background: several competing geometric and hemodynamic factors are suggested as contributing mechanisms for functional mitral regurgitation (mr) in heart failure patients. we aimed to study the relationships between the severity of mr and the qrs duration and dyssynchrony markers in patients with ischemic or dilated cardiomyopathy. methods: w e prospectively evaluated 251 heart failure patient...

  Multiple aorto-cardiac cavity communications is very rare but important complication of prosthetic aortic valve endocarditis. The case below illustrates multiple aorto-cardiac cavity fistula formation following prostethic aortic valve endocarditis presented with slowly progressive symptoms of heart failure. A brief review of surgical reconstruction and the existing literature are presented, i...

atrioventricular groove rupture is a rare, albeit mortal, complication following mitral valve surgery. avoidance is the best strategy but it cannot fully prevent the occurrence of this complication. several repair techniques have been described with varying success rates; however, the rarity of the complication precludes consensus about the safest technique. here we report two cases of posterio...

background: the adult cardiac surgery databank (acsd) of tehran heart center was established in 2002 with a view to providing clinical prediction rules for outcomes of cardiac procedures, developing risk score systems, and devising clinical guidelines. this is a general analysis of the collected data. methods: all the patients referred to tehran heart center for any kind of heart surgery betwee...

background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...

the left ventricular aneurysm is one of the most significant complications of myocardial infarction and is defined as the expansion of the ventricular wall. the coronary artery aneurysm is characterized by an abnormal dilation of the localized portion of the coronary artery, and its main cause is atherosclerosis. we herein report an unusual case of coronary artery and left ventricular aneurysms...
