Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...

OBJECTIVES This study was undertaken to investigate time trends in early mortality, morbidity and clinical characteristics of patients undergoing heart valve surgery over the last decade. METHODS A regional, prospectively collected, study comprising all patients (2,327) undergoing valve surgery in a defined geographical area from January 1990 to December 1999 was conducted. Data were collecte...

We attempted to investigate cardioprotection of electroacupuncture (EA) for enhanced recovery after surgery on patients undergoing heart valve replacement with cardiopulmonary bypass. Forty-four patients with acquired heart valve replacement were randomly allocated to the EA group or the control group. Patients in the EA group received EA stimulus at bilateral Neiguan (PC6), Ximen (PC4), Shenti...

From 1975 to 1979, 540 patients undergoing valve replacement were entered into a randomized trial and received either a Bjdrk-Shiley (273 patients) or a porcine heterograft prosthesis (initially a Hancock valve [107 patients] and later a Carpentier-Edwards prosthesis [ 160 patients]). Two hundred and sixty-two patients required mitral valve replacement, 210 required aortic valve replacement, 60...

global myocardial ischemia and ischemia-reperfusion injury are potential adverse events related with cardioplegic arrest. beating heart surgery has avoided such complications and adapted to valve surgery following successful results published on myocardial revascularization. difficulty in weaning from cardiopulmonary bypass may be lessened by using on-pump beating heart surgery for mitral valve...

BACKGROUND VKORC1 is reported to be capable of treating several diseases with thrombotic risk, such as cardiac valve replacement. Some single-nucleotide polymorphisms (SNPs) in VKORC1 are documented to be associated with clinical differences in warfarin maintenance dose. This study explored the correlations of VKORC1-1639 G/A, 1173 C/T and 497 T/G genetic polymorphisms with warfarin maintenance...

Introduction: Heart valve disease in pediatricsis an increasing global concern, especially in developing countries. This study aims to determine the clinical outcomes of pulmonary valve replacement (PVR) surgery in pediatrics. Methods: The authors retrospectively identified all pediatrics undergoing PVR surgery at Imam Reza hospital (Mashhad, Iran) between 2000 and 2020. Their medical records...

Background—The United Kingdom Heart Valve Registry (UKHVR) has recently completed collecting information on 52 659 heart valve replacements (in 47 718 patients) performed during the period 1986 to 1995 in the whole of the United Kingdom. Information stored in the UKHVR’s computer database was used for this study. Factors affecting the time from first prosthesis to first redo prosthesis were ana...

OBJECTIVES Ischaemic mitral valve regurgitation is associated with a significant reduction in survival and its treatment in patients undergoing surgical ventricular reconstruction is usually associated with higher perioperative morbidity and mortality. We evaluated our 11-year experience in this cohort of patients. METHODS Between January 2000 and December 2010, a total of 282 patients underw...
