Mineral and bone disorder is a common complication of end-stage renal disease. Notably, hyperphosphatemia likely promotes calcification of the myocardium, valves, and arteries. Hyperphosphatemia is associated with higher risk for cardiovascular mortality and morbidity along a gradient beginning at 5.0mg/dL. Among contemporary hemodialysis (HD) patients, mean serum phosphorus level is 5.2mg/dL, although 25% of patients have serum phosphorus levels of 5.5 to 6.9mg/dL; and 13%, >7.0mg/dL. Treatment of hyperphosphatemia is burdensome...

Mitral annular calcification (MAC) is a chronic degenerative process at the fibrous base of the mitral valve. It is a feared diagnosis in the context of mitral valve operations because of the risk of severe adverse events such as atrioventricular disruption, injury to the circumflex artery during debridement, and difficult placement of annular sutures. We report a series of 3 consecutive female patients with severe circular MAC who underwent successful mitral valve replacement through a lateral minithoracotomy with use of an inverted transcatheter aortic valve...

The association of aortic valve calcification (AVC) with dementia remains unknown. In 2,428 non-demented participants from the population-based Rotterdam Study, we investigated the association of CT-assessed AVC with risk of dementia and cognitive decline. AVC was present in 33.1% of the population. During a median follow-up of 9.3 years, 160 participants developed dementia. We found no association between presence of AVC and risk of all-cause dementia [hazard ratio (HR): 0.89 (95% confidence interval (CI):0...

PURPOSE OF REVIEW: Elevated plasma concentrations of lipoprotein(a) (Lp(a)) are an independent and causal risk factor for cardiovascular diseases including coronary artery disease, ischemic stroke, and calcific aortic valve stenosis. This review summarizes the rationale for Lp(a) lowering and surveys relevant clinical trial data using a variety of agents capable of lowering Lp(a). RECENT FINDINGS: Contemporary guidelines and recommendations outline populations of patients who should be screened for elevated Lp(a) and who might benefit from Lp(a) lowering...

Calcific aortic valve disease (CAVD) is a major cardiovascular disorder in the developed countries. Male is a known risk factor in this disease; unfortunately, how sex contributes to CAVD is mostly unknown. The objective of this study is to determine whether valvular interstitial cells (VICs) isolated from male versus female aortic valves demonstrate difference in osteogenic differentiation and/or extracellular matrix (ECM) remodeling. VICs were isolated from male and female rat or porcine aortic valves and cultured in osteogenic media for 10, 15 and 20 days...

Cardiovascular disease and osteoporosis are major age-related causes of morbidity and premature death that occur among older adults. Emerging evidence suggests that calcium from bone is deposited in the arteries. This leads to calcification in valves and vessels, which is associated with a 3-4 fold higher risk of coronary heart disease. Calcium and vitamin D supplementation is frequently advised in older adults for the prevention of osteoporosis and to reduce the risk of fractures and falls. However, recent RCT's showed that individuals taking calcium and vitamin D were at higher risk of cardiovascular disease...

AIMS: Mitral annular calcification (MAC) negatively influences outcomes in surgical mitral valve (MV) repair for mitral regurgitation (MR). However, there are no data on whether MAC impacts on outcomes of MitraClip percutaneous MV edge-to-edge repair. This study sought to investigate whether the presence of MAC impacts on the procedural success and durability of percutaneous transcatheter repair of MR using the MitraClip. METHODS AND RESULTS: One hundred and seventy-three patients undergoing MitraClip repair for significant MR were studied...

Transcatheter Aortic Valve Implantation (TAVI) is a well-described treatment for symptomatic calcific severe aortic stenosis. However, TAVI technology is being increasingly used around the world to treat selected cases of severe aortic regurgitation (AR). One of the main limitations of using TAVI technology for AR is the lack of calcification, which is common in such cases. This makes anchoring of a TAVI prosthesis to the aortic annulus difficult and risks displacement or embolization. However, with the availability of recapturable and repositionable TAVI technologies, these limitations have been overcome to a large extent...

BACKGROUND: Avulsion of the aortic valve commissure as a cause of acute aortic valve regurgitation is mostly due to trauma, infective endocarditis, or ascending aortic dissection. Nontraumatic avulsion of the aortic valve commissure is very rare. We reviewed the literature and analyzed potential risk factors of nontraumatic avulsion. CASE PRESENTATION: An 80-year-old male with hypertension was seen in the emergency department with acute onset dyspnea. Echocardiogram revealed left ventricular hypertrophy with adequate systolic function, prolapse of the noncoronary cusp, and incomplete coaptation of the right coronary and noncoronary cusps with severe aortic valve regurgitation...

The recent literature on transcatheter aortic valve replacement (TAVR) is shedding new light on the perspective to extend this procedure to other lower risk-category of patients, leading in fact to a potential erosion of the current guidelines. Notwithstanding the warnings provided in the literature regarding the risk of severely impairing complications, unclear survival advantage and cost-inefficiency, many observational studies, especially performed in high-volume centers, support a general drive toward the recruitment of intermediate-low risk patients in the expectation of clinical advantages versus standard surgical replacement...

BACKGROUND: Calcium deposits in the aortic valve and mitral annulus have been associated with cardiovascular events and mortality. However, there is no accepted standard method for scoring such cardiac calcifications, and most existing methods are simplistic. The aim of this study was to test the hypothesis that a semiquantitative score, one that accounts for all visible calcium on echocardiography, could predict all-cause mortality and stroke in a graded fashion. METHODS: This was a retrospective study of 443 unselected subjects derived from a general echocardiography database...

Severe pulmonary stenosis presents early in life; late presentation is rare. Very late presentation like in our case is rarest of rare. Likewise calcification of pulmonary valve is rare. We describe here, one such case in an eighty-one year old female who astonishingly not only tolerated severe form of pulmonary stenosis but had also gone through three full term pregnancy, successfully without any untoward effect!

End stage renal disease has a list of consequences, cardiovascular being the most common. Inefficient dialysis can cause significant deposition of calcium all over the body, including heart valves making heart function impaired. We illustrate a case of 38-year-old female with end stage renal disease on peritoneal dialysis. The patient had been complaining of pain and swelling of the right hand for the last few months and had been seen by hand surgeon and was admitted electively for the biopsy of hand lesions...

BACKGROUND AND PURPOSE: It remains uncertain whether aortic valve calcification (AVC) is a risk factor for stroke. METHODS: From the population-based Rotterdam Study, 2471 participants (mean age: 69.6 years; 51.8% women) underwent computed tomography to quantify AVC. We assessed prevalent stroke and continuously monitored the remaining participants for the incidence of stroke. Logistic and Cox regression models were used to investigate associations of AVC with prevalent stroke and risk of incident stroke...

AIMS: Previous studies have shown that aortic valve calcification (AVC) was associated with cardiovascular events and mortality. On the other hand, periprocedural myocardial injury (PMI) in percutaneous coronary intervention (PCI) is a well-known predictor of subsequent mortality and poor clinical outcomes. The purpose of the study was to assess the hypothesis that the presence of AVC could predict PMI in PCI. METHODS: This study included 370 patients treated with PCI for stable angina pectoris...

BACKGROUND: 18F-Fluoride positron emission tomography (PET) and computed tomography (CT) can measure disease activity and progression in aortic stenosis. Our objectives were to optimize the methodology, analysis, and scan-rescan reproducibility of aortic valve 18F-fluoride PET-CT imaging. METHODS AND RESULTS: Fifteen patients with aortic stenosis underwent repeated 18F-fluoride PET-CT. We compared nongated PET and noncontrast CT, with a modified approach that incorporated contrast CT and ECG-gated PET...

INTRODUCTION: the relevance of intrauterine infections is determined by significant peri- and postnatal loss as well as health impairment, which often results in disability and reduced quality of life. Ultrasonography is employed in order to provide a reliable assessment of the functional state of the fetoplacental system secondary to intrauterine fetal infection in the course of pregnancy. Ultrasound imaging is essential in diagnosis of various preclinical complications of pregnancy and detection of abnormalities in the developing fetus...

BACKGROUND: The most common valve diseases are calcific aortic stenosis (AS) and aortic regurgitation (AR). The former is characterized by thickening of valve leaflets followed by progressive calcification, which produces progressive aortic valve (AV) narrowing, increased pressure afterload on the left ventricle (LV) and subsequent LV hypertrophy. On the other hand, AR is due to malcoaptation of the valve leaflets with resultant diastolic reflux of blood from aorta back to the LV producing volume and pressure overload and progressive LV dilatation...

Since the 1990's cabergoline has been the treatment of choice in prolactinoma, as it permits rapid and effective hormonal and tumor control in most cases. Evidence of cardiac valvulopathy was demonstrated in Parkinson's disease patients treated with dopamine agonists. Retrospective studies in prolactinoma patients treated with cabergoline at lower doses did not show such an effect. However, few prospective data with long-term follow-up are available. The aim of this study was to assess the safety of cabergoline regarding cardiac valvular status during prospective follow-up in patients treated for prolactinoma or idiopathic hyperprolactinemia...
