The association between the aortic root diameter and aortic regurgitation in hypertensive and normotensive people is still disputed, and the underlying mechanisms remain to be clearly elucidated. We aimed to investigate the relationship between the aortic root diameter and trivial to mild functional aortic regurgitation in never-treated hypertensive patients with a new diagnosis compared with healthy normotensive participants.
A total of 182 hypertensives and 232 age-matched normotensives were included in the study.

Filamin A (FLNA) is located in Xq28, and encodes the actin binding protein, filamin A. A mutation in FLNA is the most common cause of periventricular nodular heterotopia (PVNH), but a clear phenotype-genotype correlation has not been established. Indeed, some patients with a FLNA mutation have recently been shown to additionally have Ehlers-Danlos-like collagenopathy or macrothrombocytopenia.

Recently, implantable cardioverter-defibrillators (ICD) have become capable of monitoring intrathoracic impedance to detect an increased fluid volume and heart failure. Pregnancy is a well-known cause of an increased body fluid volume; however, it is not clear whether the measurement of intrathoracic impedance by ICD is clinically useful for precisely detecting heart failure in pregnant women. We herein report the case of a 39-year-old woman with an ICD that had been implanted after an event of ventricular fibrillation due to severe aortic regurgitation with a bicuspid aortic valve.

The transcatheter aortic valve implantation (TAVI) consist an alternative treatment in patients with severe aortic stenosis. Multimodality imaging using transthoracic echocardiography (TTE) or transesophageal echocardiography (TOE) and multislice CT (MSCT) constitute cornerstone techniques for the pre-operative management, peri-procedural guidance, follow up and recognition of possible transcatheter valve related complications. CT angiography is much more accurate regarding the total definition of aortic annulus diameter and circumferential area.

We report the case of a patient with mitral regurgitation complicated by type B dissection and Marfan syndrome (MFS) who was managed successfully with minimally invasive mitral valve repair. Without type A aortic dissection or aortic root dilation, MFS patients may develop mitral valve regurgitation, as in this case, and need valve surgery to improve their symptoms and long-term survival. However, it is not clear that a full sternotomy and prophylactic aortic surgery are necessary.

Patients with double-inlet left ventricle usually have a small ascending aorta. In the Norwood procedure, which involves a staged operation, a neoaorta is constructed with a homograft, and the pulmonary artery plays a role in the systemic circulation. Dilatation or aneurysmal changes can occur over time due to the exposure of the neoaorta to systemic pressure, which may induce adverse effects on adjacent structures.

Marfan syndrome is an autosomal dominant genetic disorder that affects connective tissue and is caused by mutations in the fibrillin 1 gene present at chromosome 15. Aortic aneurysm is its main complication, and along the dilation of the aorta root and its descending portion (60-100%), with secondary aortic insufficiency, it increases risk of acute aortic dissection and death. Coronary artery anomalies affect between 0.

Semin Thorac Cardiovasc Surg Pediatr Card Surg Annu 2018 Mar;21:33-40
Chawki ElZein, David Roberson, Nour Hammad, Michel Ilbawi
At present, aortic valvuloplasty is considered an effective procedure for treatment of aortic regurgitation in pediatric patients. It has encouraging mid- and long-term results. The improved outcome is primarily related to better understanding of the functional anatomy of the normal valve and the different factors that alter it.

Transcatheter procedures have overtaken conventional operations in Germany. Considering that this is a highly competitive field, a rate of 25% for minimal access aortic valve replacement seems to be disappointingly low. One way to promote minimal access techniques is through the systematic use of rapid deployment valves.

Excess dilatation of the left atrium >65 mm is known in the literature as gigantic atrium. This dilation is most commonly encountered in the mitral insufficiency of rheumatic etiology, but also in severe prolapses of the mitral valve, permanent atrial fibrillation, and at the left right shunt with cardiac insufficiency.
In this paper is presented a case study of echocardiographically verified giant thrombus in left atrium in a 50 years old female patient aged 50 hospitalized because of tiredness, choking, heartburn and urinary tract symptoms.

Subaortic septal myectomy is usually performed to mitigate obstruction in patients with the obstructive form of hypertrophic cardiomyopathy (HCM) or in those with congenital subaortic stenosis. Moreover, it is combined with aortic valve replacement in patients with severe aortic valve stenosis (SAS) and asymmetrical septal hypertrophy causing concomitant left ventricular outflow tract obstruction. When both conditions coexist, it is conceptually difficult to identify a cardiomyopathy beyond an adaptive myocardial hypertrophy, strictly related to pressure overload.

Nowadays, percutaneous pulmonary valve implantation (PPVI) is a suitable alternative to surgical procedure in patients with right ventricle outflow tract dysfunction. Two valves are currently available for PPVI: the Melody valve and the Edwards Sapien valve. The following complications may occur: coronary artery compression, deformation of the aortic root, stent or valve embolization, damage of distal pulmonary arteries, access site injuries.

Due to the absence of annular calcification for device anchoring, it is presumed that transcatheter aortic valve replacement (TAVR) is not suitable for the treatment of native aortic valve regurgitation (NAVR) resulting in very limited data and experience concerning its safety and efficacy. We sought to review published data on the safety and efficacy of TAVR in high-risk patients with NAVR. Studies including case reports, case series and original articles published between 2002 and 2016 on TAVR in patients with NAVR were identified with a systematic electronic search using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.

Gastrointestinal Bleeding in Native and Prosthetic Valve Disease.

Curr Treat Options Cardiovasc Med 2018 Feb 3;20(1). Epub 2018 Feb 3.
Joseph L Blackshear
Gastrointestinal bleeding with severe aortic stenosis was originally described in the 1950s by Heyde, although for years, the association was debated. Further discovery of mechanisms and the ubiquity and severity of acquired von Willebrand syndrome in the left ventricular assist device therapy have removed any doubts. At this time, gastrointestinal bleeding from intestinal angiodysplasia in patients with turbulence-related proteolysis of the highest molecular weight multimers of von Willebrand factor is now known to occur in patients with aortic stenosis, and also subaortic obstruction and associated mitral insufficiency in hypertrophic cardiomyopathy, isolated mitral and aortic insufficiency, endocarditis, and in patients with prosthetic valve dysfunction, either from stenosis or insufficiency.

Trans-carotid access for trans-catheter aortic valve replacement is a valid alternative in patients with aortic valve dysfunction, severe peripheral vascular disease, and high-risk for surgery. However, in the event of the need for a bailout valve-in-valve procedure, the safety of this access site is uncertain. We report a patient with aortic regurgitation, previous coronary surgery, peripheral vascular disease, and impaired ventricular function who underwent a CoreValve Evolut-R (Medtronic Inc, Minneapolis, MN) implantation through the left carotid artery followed by a successful valve-in-valve procedure with a 26-mm Edwards Sapien3 valve (Edwards Lifesciences, Irvine, CA) through the same carotid access site.

We report the successful surgical treatment of aortic regurgitation in a 27-year-old woman with Turner syndrome (TS) who was admitted with exacerbation of dyspnea on exertion. Echocardiography showed a bicuspid aortic valve with severe aortic regurgitation and computed tomography showed dilatation of the ascending aorta and aortic root. Due to the patient's low body surface area (due to TS), standard determination of aortic size was not possible; therefore, we used the reference curves of aortic diameters in children.
