background: pregnant patients with mechanical heart valves require anticoagulation. the risk of bleeding and embryopathy associated with oral anticoagulants must be weighed against the risk of valve thrombosis. methods: in this prospective study, undertaken between 1999 and 2009, 53 pregnancies (47 women with mechanical mitral valves; 29.8 ± 4.8 years old) were studied. patients were divided in...

introduction cerebral haemorrhage could complicate post operative course after cardiac surgery, especially after multiple mechanical valves replacement needing for anticoagulation. the interruption of vitamin k antagonists in this cases, to avoid the enhancement of the cerebral haemorrhage, can be performed with reasonable safety. case presentation we report the case of a patient who underwent ...

Prosthetic thrombosis is a rare complication, but it has high mortality and morbidity. Young women of childbearing age that have prosthetic heart valves are at increased risk of thrombosis during pregnancy due to changes in coagulation factors. Anticoagulation with adequate control and frequent follow-up if pregnancy occurs must be performed in order to prevent complications related to anticoag...

mitral valve replacement (mvr) is usually performed in two methods of running and interrupted suturing. in running method, the suturing of the valve is usually with some traction on the annulus and also there is a risk of aortic valve injury. this study was conducted to evaluate a new technique for suturing to avoid these complications and decrease the time of cardiac arrest. one hundred and se...

Classical aortic valve replacement is often fraught with negative outcomes for patients. When replacing the a mechanical prosthesis, patient associated life use of indirect anticoagulants, which leads to hemorrhagic and thrombotic complications. In case biological fairly frequent complication early calcification and, consequently, high frequency dysfunctions prosthesis. addition, prosthetics he...

transcatheter aortic valve implantation (tavi) is a new therapeutic option for patients with severe aortic stenosis with unacceptable surgical risk for conventional aortic valve surgery. a bicuspid aortic valve (bav) is the most common congenital cardiac disorder (1% of the population) and currently is considered exclusion criteria for tavi, because it predicts an increased risk of adverse aort...

INTRODUCTION Patients with mechanical heart valve prostheses must continuously be treated with oral anticoagulants to prevent thromboembolic events related to prosthetesis. These patients should be continually evaluated for the control of oral anticoagulation. OBJECTIVE To compare the occurrence of thromboembolic and hemorragic complications in patients with mechanical heart valve prosthesis ...

abstract background: few attempts were made for alleviating the physical/psychological problems among the cardiac valve–replaced patients and no comprehensive study was done based on the experiences of such patients. this study was undertaken to describe the stressful experiences of the heart valve-replaced patients. materials and methods: in this qualitative study performed during 2012-2013 wi...

conclusions high risk patients needing avr are optimal candidates for transcatheter aortic valve implantation. tavi is a valuable solution for high risk patients needing avr. obtained results are comparable to results in transthoracic avr in standard candidates for aortic valve implantation. background transcatheter aortic valve implantation (tavi) has emerged as an alternative treatment to cla...

background : prosthetic valve endocarditis (pve) is an important cause of morbidity and mortality associated with heart valve replacement surgery. the aim of the present study was to describe the early outcome of treatment in patients with pve in a single center. methods : the data of all the episodes of pve registered at our institution between 2002 and 2007 were collected and analyzed retrosp...
