Functional tricuspid valve (TV) regurgitation secondary to left heart disease (e.g. mitral insufficiency and stenosis) is observed in 75% of the patients with TV regurgitation and is thus the most common etiology; therefore, the majority of patients who require TV surgery, undergo concomitant mitral and/or aortic valve surgery. Uncorrected moderate and severe TV regurgitation may persist or even worsen after mitral valve surgery, leading to progressive heart failure and death. Patients with moderate to severe TV regurgitation show a 3-year survival rate of 40%...

AIMS: Transcatheter mitral valve replacement (TMVR) is a novel technique for treating mitral regurgitation. We report 18-month/2-year outcomes of the 5 first-in-man patients undergoing chronic TMVR with the Tendyne device. METHODS AND RESULTS: Five patients (STS score 14%-23%) underwent TMVR using a Tendyne system under compassionate use at a single centre. 1 patient (who was noncompliant with anti-coagulation) died 9 months after TMVR following a cerebrovascular accident...

BACKGROUND AND AIM: Tricuspid valve replacement has been associated with high mortality and poor long-term outcomes. We report the preoperative risk factors associated with short and long-term outcomes following tricuspid valve replacement with mechanical prostheses. METHODS: In 62 patients who underwent mechanical tricuspid valve replacement, clinical, laboratory, and echocardiographic findings were analyzed using both univariate and multivariate analyses to describe operative and long-term mortality...

PURPOSE: Significant late-onset tricuspid regurgitation (TR) is unfortunately common after double valve replacement (DVR); however, its underlying factors remain undefined. We evaluated the effect of aortic patient-prosthesis mismatch (PPM) on late-onset TR and clinical outcomes after DVR. MATERIALS AND METHODS: Of the 2392 consecutive patients who underwent aortic valve replacement between January 1990 and May 2014 at our institution, we retrospectively studied 462 patients who underwent DVR (excluding concomitant tricuspid valvular annuloplasty or replacement)...

Tricuspid valve regurgitation is frequently found as a result of right ventricular remodeling due to advanced left heart diseases. Drug treatment is limited to diuretics and the cardiac or pulmonary comorbidities. Due to the high risk only a small percentage of patients are amenable to surgical treatment of tricuspid regurgitation in those who undergo left-sided surgery for other reasons. Catheter-based procedures are an attractive treatment alternative, particularly since the strong prognostic impact of tricuspid regurgitation suggests an unmet need of treatment, independent of the underlying heart disease...

Cellular and molecular mechanisms of thoracic aortic aneurysm are not clear and therapeutic approaches are mostly absent. Thoracic aortic aneurysm is associated with defective differentiation of smooth muscle cells (SMC) of aortic wall. Bicuspid aortic valve (BAV) comparing to tricuspid aortic valve (TAV) significantly predisposes to a risk of thoracic aortic aneurysms. It has been suggested recently that BAV-associated aortopathies represent a separate pathology comparing to TAV-associated dilations. The only proven candidate gene that has been associated with BAV remains NOTCH1...

Hypoplastic Left Heart Syndrome (HLHS) is one of the most challenging congenital heart defects which require surgical interventions during neonatal period. In normal risk cohort, its surgical outcome has been improved dramatically since Dr. William Norwood reported the 1st successful case more than 30 years ago. The introduction of routine bilateral pulmonary artery banding with subsequent Norwood operation during early infantile( we call it as "rapid 2 stage Norwood operation") has brought an earlier hemodynamic stabilization after Norwood operation...

REVIEW
Michael H Kwon, Thoralf M Sundt
The bicuspid aortic valve (BAV) phenotype is becoming increasingly recognized as a complex and heterogeneous clinical entity, with some but not all patients developing accelerated degrees of both aortic insufficiency (AI) and aortic stenosis (AS) in comparison to patients with tricuspid aortic valves (TAV). In addition, there remains a well-established association between the BAV phenotype and aortic enlargement independent of valve function as well as progression among some to ascending aortic aneurysm and the attendant concern over risk of aortic dissection...

OBJECTIVES: Rheumatic mitral stenosis (MS) is a progressive disease, and risk of death may persist despite relief of the obstruction. Net atrioventricular compliance (Cn) modulates the overall haemodynamic burden of the MS and may be useful in predicting cardiovascular death after percutaneous mitral valvuloplasty (PMV). METHODS: A total of 427 patients (mean age 50±16 years, 84% female) with severe MS undergoing PMV were enrolled. Doppler-derived Cn was estimated at baseline using a previously validated equation...

Good quality of life correlates with a good exercise capacity in daily life in patients with tetralogy of Fallot (ToF). Patients after correction of ToF usually develop residual defects such as pulmonary regurgitation or stenosis of variable severity. However, the importance of different hemodynamic parameters and their impact on exercise capacity is unclear. We investigated several hemodynamic parameters measured by cardiovascular magnetic resonance (CMR) and echocardiography and evaluated which parameter has the most pronounced effect on maximal exercise capacity determined by cardiopulmonary exercise testing (CPET)...

An aortic aneurysm is a lethal arterial disease that mainly occurs in the thoracic and abdominal regions of the aorta. Thoracic aortic aneurysms are prevalent in the root/ascending parts of the aorta and can lead to aortic rupture resulting in the sudden death of patients. Understanding the biomechanical and histopathological changes associated with ascending thoracic aortic aneurysms (ATAAs), this study investigates the mechanical properties of the aorta during strip-biaxial tensile cycles. The loss factor-defined as the ratio of dissipated energy to the energy absorbed during a tensile cycle-the incremental modulus, and their anisotropy indexes were compared with the media fiber compositions for aneurysmal (n = 26) and control (n = 4) human ascending aortas...

Fetuses with pulmonary atresia or pulmonary stenosis with intact ventricular septum manifest variable degrees of right ventricle hypoplasia and inadequacy. We studied the relationship between prenatal echocardiographic parameters and their progression through gestation as potential predictors of postnatal single-ventricle or two-ventricle care strategy. Serial fetal echocardiograms of pulmonary atresia (n = 28) or severe pulmonary stenosis (n = 8) and intact ventricular septum were reviewed. Measurements included tricuspid valve and mitral valve diameter and Z scores, degree of tricuspid regurgitation, presence of subaortic stenosis, presence of coronary artery fistulae, and Doppler pulsatility indices in middle cerebral and umbilical artery...

Tricuspid atresia (TA) is a rare congenital heart defect in which the right atrioventricular connection, the tricuspid valve, is absent. As a result, there is no direct communication between the right atrium and right ventricle. Surgical treatment, including the Fontan procedure, is indicated yet palliative, leaving patients with various lifelong complications. A comprehensive literature review revealed a paucity of evidence-based education on the identification, evaluation, management, treatment, and life span implications of TA...

INTRODUCTION: Myocardial contusion is an entity in chest trauma which is difficult to diagnose. Current practice relies more on cardiac-specific biochemical markers and standard echocardiography, but no gold standard test exists. The application of Tissue Doppler imaging is yet unexplored. AIM: The present study was designed to evaluate cardiac injury in patients with blunt trauma chest using conventional trans-thoracic echocardiography parameters and Tissue Doppler imaging...
