Abstract Recurrent implantation failure (RIF) is an imprecisely defined disorder lacking a robust scientific basis. The incomplete understanding of RIF provides significant diagnostic and therapeutic challenges, better the underlying issues necessary to improve outcomes. We propose novel concept termed ‘Theoretical Cumulative Implantation Rate’, calculation which based on objective data, define...

Objective: There are very limited data of complications pacemaker implantation in Vietnam
 Method and Results: From 1/2015 to 12/2019, 1227 consecutive patients with bradycardias, aged 60,39 ± 18,93 years (40,34% male) were underwent the implantation. Models is 59,01% one chamber device 40,99% two chambers device. Early pneumothorax 0,24%, hematoma pocket 1,87%, lead dislodgment 0,57%. Lat...

OBJECTIVE To evaluate the use of left ventricular assist devices (LVAD) as bridge to heart transplantation (HTx) in patients with end-stage heart failure. METHOD Between March 1993 and December 2001, 38 patients with refractory end-stage heart failure underwent HeartMate LVAD (Thoratec, Pleasanton Calif.) implantation. RESULTS A total of 33 of the 38 patients (87%) survived the implantation...

conclusions in this study, sick sinus syndrome and pacemaker mode followed by syncope were independently associated with increased mortality. results survival data were available for 1030 (80%) patients (median age = 71 years [5th to 95th percentile range: 26 - 86 years]) and follow-up was completed for 84.28% of them. according to the results, 56% of the patients had received dual-chamber syst...

Biventricular devices play an important adjunctive role in the treatment of heart failure. However, biventricular device implantation is associated with significant radiation exposure and a high proportion of non-response to cardiac resynchronization therapy (CRT). The use of electroanatomic mapping (EAM) during biventricular device implantation may help overcome these issues. This article will...

The success of reproduction, although gradually increasing over the years, many couples also had been left frustrated following repeated failed attempts. Implantation of the embryo, can only take place in a receptive uterus and inadequate uterine receptivity is responsible for approximately two-thirds of implantation failures. Endometrial receptivity can be reduced by morphological and/or molec...

As numerical and structural defects in chromosomes are an inevitable consequence of IVF, Pre-implantation genetic diagnosis and screening (PGD/PGS) methods are used for detecting abnormalities in embryos before implantation to the uterus to increase the successful rate of IVF. Pre-implantation genetic diagnosis and screening approaches can be achieved by different techniques such as NGS, CGH an...

Background-Failure ofthe donor (graft) heart is the main cause ofmortality in the first month after orthotopic cardiac transplantation. In a preliminary study marked downregulation of cardiac fp adrenoceptor density was found in apparently normal donor hearts ofrecipients who developed severe cardiac failure soon after implantation. Cardiac fl adrenoceptors are an important factor in the develo...

BACKGROUND Failure of the donor (graft) heart is the main cause of mortality in the first month after orthotopic cardiac transplantation. In a preliminary study marked downregulation of cardiac beta adrenoceptor density was found in apparently normal donor hearts of recipients who developed severe cardiac failure soon after implantation. Cardiac beta adrenoceptors are an important factor in the...
