Though relatively rare, quadricuspid truncal valves are associated with significant valve regurgitation that often necessitates surgical correction. We present the repair of a quadricuspid truncal valve using a bicuspidization technique.

MicroRNAs are able to modulate gene expression in a range of diseases. We focused on microRNAs as potential contributors to the pathogenesis of ascending aorta (AA) dilatation in patients with stenotic tricuspid (TAV) or bicuspid aortic valve (BAV). Aortic specimens were collected from the 'concavity' and the 'convexity' of mildly dilated AAs and of normal AAs from heart transplant donors. Aortic RNA was analyzed through PCR arrays, profiling the expression of 84 microRNAs involved in cardiovascular disease...

BACKGROUND: Two-dimensional (2D) echocardiography is one of the most feasible, noninvasive methods for assessing the aortic diameter and biomechanical changes. We studied possible interfaces between noninvasive biomechanical and speckle-tracking (ST) echocardiographic data from dilated aortas. METHODS: Altogether, 44 patients with dilative pathology of ascending aorta (DPAA) were compared with subjects without ascending aortic dilation (diameter <40 mm). DPAA patients formed two groups based on diameter size: group 1, ≤45 mm diameter; group 2, >45 mm...

BACKGROUND: We aimed to identify the clinical and echocardiographic determinants of symptoms and their prognostic implications in patients with moderately dysfunctional bicuspid aortic valves (BAVs). METHODS: Among 1,019 subjects in the BAV registry treated in a single tertiary care center, the records of 127 patients (85 men, age 58±13 years) with moderately dysfunctional BAVs were comprehensively reviewed. The patients were divided into two groups based on symptom status: asymptomatic (n = 80) vs...

Importance: Little is known about the association between bicuspid aortic valve (BAV) morphologic findings and the degree of valvular dysfunction, presence of aortopathy, and complications, including aortic valve surgery, aortic dissection, and all-cause mortality. Objective: To investigate the association between BAV morphologic findings (raphe vs nonraphe) and the degree of valve dysfunction, presence of aortopathy, and prognosis (including need for aortic valve surgery, aortic dissection, and all-cause mortality)...

OBJECTIVE: Present study is an evaluation of left atrial (LA) mechanical and conduction function in patients with bicuspid aortic valve (BAV) without significant valve dysfunction, and an investigation of relationship between LA function and aortic elasticity. METHODS: Study population consisted of 34 isolated BAV patients (mean age: 34±13 years) and 29 healthy, age- and sex-matched volunteers (mean age: 30±10 years). LA volume was measured using biplane area-length method and LA active and passive emptying volume and fraction was calculated...

Despite the widespread use of transcatheter aortic valve replacement (TAVR) for moderate and high-risk patients with severe aortic stenosis, it is utilized less frequently in patients with bicuspid aortic valves (BAV). Orthotopic heart transplant (OHT) donors tend to be younger and may have undiagnosed BAV. We present a case of successful TAVR in a patient with BAV thirteen years after OHT.

OBJECTIVES: Prospective analysis of left ventricular (LV) morphological/functional parameters in patients with bicuspid versus tricuspid aortic valve (TAV) stenosis undergoing aortic valve replacement (AVR) surgery. METHODS: A total of 190 consecutive patients with BAV (n = 154) and TAV stenosis (n = 36) (mean age 61 ± 8 years, 65% male) underwent AVR ± concomitant aortic surgery from January 2012 through May 2015. All patients underwent preoperative cardiac magnetic resonance imaging in order to evaluate: (i) left ventricular outflow tract (LVOT) dimensions, (ii) length of anterior mitral leaflet (AML), (iii) end-systolic and end-diastolic LV wall thickness, (iv) LV area, (v) LV end-systolic and end-diastolic diameters (LVESD, LVEDD), (vi) LV end-diastolic and end-systolic volumes (LVEDV, LVESV) and (vii) maximal diameter of aortic root...

BACKGROUND: -Prenatal diagnosis of Coarctation of the Aorta (CoA) is still challenging and affected by high rates of false positive diagnoses. The aim of this study was to ascertain the strength of association and to quantify the diagnostic accuracy of different ultrasound signs in predicting CoA prenatally. METHODS: -Medline, Embase, CINAHL and Cochrane databases were searched. Random-effect and HSROC model meta-analyses were used to analyse the data. RESULTS: -794 articles were identified and 12 (922 fetuses at risk for CoA) were included...

Bicuspid aortic valve (BAV) disease is associated with aortic dilatation. Timing of follow-up and surgery is challenging. Hence, there is an unmet clinical need for additional risk stratification. It is unclear whether valve morphology is associated with dilatation rates. Therefore, the objective of this study was to examine the association between clinical and echocardiographic determinants (including valve morphology) and aortic dimension and the progression rate of dilatation.Aortic dimensions were assessed on serial echocardiographic images between 1999 and 2014 in a population of 392 patients with BAVs in a tertiary care center in the Netherlands...

The relationships between water mite larvae parasitizing Coenagrion scitulum in core and edge populations were described. A total of 636 larvae of 7 water mite species were found on 143 C. scitulum adults (82 females and 61 males). C. scitulum was recorded for the first time as a host species for Arrenurus cuspidator, A. bruzelii, A. bicuspidator, A. tricuspidator, A. claviger and Hydryphantes octoporus. The degree of infestation by particular parasite species was typical for these species. In contrast, the parasites' preferences for host body parts were not typical, as they preferred abdominal segments 2-4, which in earlier studies had been avoided by water mite larvae...

BACKGROUND: The study aim was to evaluate the long-term clinical outcomes of the modified Bentall procedure (MBP) with a mechanical conduit. METHODS: Between 1993 and 2014, a total of 249 patients (mean age 62 ± 12 years; range: 25-87 years) underwent a MBP at the authors' institution. The main indication was annuloaortic ectasia in 102 patients (41%), followed by acute aortic dissection in 82 patients (33%); moderate to severe aortic regurgitation was present in 79% of cases...

Aortic valve repair is still emerging, and its role in the treatment of bicuspid aortic valve disease (BAVD) is not yet fully understood. Our objective is to synthesise available evidence on outcomes after surgical aortic valve repair in patients with BAVD. We conducted a systematic review of clinical studies using prespecified methods for searching, identifying and selecting eligible studies in 4 databases, and synthesising results (PROSPERO 2014:CRD42014014415). 2 researchers independently reviewed full-text articles and extracted data...

INTRODUCTION: Treatment guidelines for the thoracic aorta concentrate on size, yet acute aortic dissection or rupture can occur when aortic size is below intervention criteria. Functional imaging and computational techniques are a means of assessing haemodynamic parameters involved in aortic pathology. SOURCES OF DATA: Original articles, reviews, international guidelines. AREAS OF AGREEMENT: Computational fluid dynamics and 4D flow MRI allow non-invasive assessment of blood flow parameters and aortic wall biomechanics...

BACKGROUND: Bicuspid aortic valve (BAV)-related aortopathy is characterized by histological abnormalities that result in aortic wall stiffening and aortic dilation. The study aim was to determine the range of ascending aortic stiffness seen in a clinical cohort of patients with BAV, and to identify the association of aortic stiffness with standard clinical and imaging parameters. METHODS: Patients with BAV (n = 65) and normal subjects (n = 10) were studied using conventional phase-contrast magnetic resonance imaging through the ascending aorta...

BACKGROUND: The study aim was to prospectively analyze the impact of cusp fusion pattern on aortopathy severity in patients undergoing surgery for bicuspid aortic valve (BAV) stenosis. METHODS: A total of 137 consecutive patients with BAV stenosis (93 males, 44 females; mean age 61 ± 9 years) underwent aortic valve replacement with or without concomitant aortic surgery between January 2012 and March 2015. All patients underwent preoperative cardiac magnetic resonance imaging (cMRI) in order to evaluate morphological/functional parameters of the aortic root...
