Chronic atrial fibrillation in presence of aortic stenosis in a patient with polysplenia syndrome.

2013

We report a rare case of “situs viscerum ambiguous” with polysplenia syndrome, in a 69 year old female patient with aortic stenosis and chronic atrial fibrillation. The presenting symptom was dyspnoea on moderate exertion and an ECG showed supra ventricular arrhythmia. Patients trans-thoracic echocardiogram revealed a dilated left atrium, reduced ejection fraction, mild tricuspid regurgitation, moderate-severe pulmonary hypertension and severe aortic stenosis. The patient was successfully treated with a replacement of her aortic valve and ascending aorta.

Background Transcatheter aortic valve implantation (TAVI) has become the treatment of choice in patients with severe aortic valve stenosis who are not eligible for operative replacement and an alternative for those with high surgical risk. Due to high age and smoking history in a high proportion of TAVI patients, suspicious findings are frequently observed in pre-procedural chest computer tomography (CCT).

Use of transoesophageal echocardiography in the diagnosis of abscess in infective endocarditis

1995

Transoesophageal echocardiography is invaluable clinically since it accurately images abscess cavities or aneurysms. It provides the information about the site and extension of abscesses which is needed by surgeons to time and define surgical intervention. Early diagnosis is advantageous, and abscesses should be expected in 5%-30% of patients with echocardiographically discernible vegetations. Since there is no 'abscess typical' organism, transoesophageal echocardiographic examination is helpful at the first indication of infective endocarditis, to identify high-risk patients. Involvement of the aortic valve, growth in the size of vegetations, and the presence of spontaneous echo contrast a…

Identification of cardiac organ damage in arterial hypertension: insights by echocardiography for a comprehensive assessment

2020

: Arterial hypertension, a widespread disease, whose prevalence increases with age, represents a major risk factor for cardiovascular events, causing damage in several organs, including the heart. In this context, echocardiography has a clear and pivotal role, being able to assess cardiac morphology and detect haemodynamic changes induced by this disease. 2018 European Society of Cardiology/European Society of Hypertension guidelines on AH identified main echo parameters such as left ventricular mass, relative wall thickness and left atrial volume, for detecting cardiac organ damage. The present review highlights the advantage of additional echocardiographic parameters such as diastolic mea…

To the research of treatments for the typical calcific disease of old aortic valve in the omics era: Is the miR-195 a therapeutic signature via targe…

2020

Calcific aortic valve disease (CAVD) is the most frequent form of val-vular pathology [1,2], with high percentages of mortality and morbidityin Western populations, so much to be a very public health problem [2].Diverse millions of subjects are affected by CAVD and the major numberare old individuals (65- older), even if some have a younger age and aregenerally affected by congenital bicuspid aortic valve (BAV) disease[2,3]. CAVD in BAV individuals arises decades earlier respect to subjectswith the physiological tricuspid aortic valve [3]. Furthermore, it can leadto death if untreated with surgical aortic valve replacement or trans-catheter aortic valve implantation, its unique treatments […

Three-Dimensional Echocardiographic Evaluation of Aortic and Mitral Valve Stenosis

2001

Dynamic volume rendered three-dimensional echocardiography allows the spatial recognition of anatomy and function of the aortic and mitral valves with acceptable image quality. The aortic valve can be best visualized in a view from the ascending aorta down to the valve level, thus allowing an overview of the aortic aspect of the valve in a surgeon's perspective in ∼ 80% of patients. Planimetric measurement of the aortic valve area was possible in 88% of patients, and there is no systematic overestimation or underestimation of aortic valve area compared with two-dimensional echocardiography and catheterization. The entire valvular circumference of the mitral valve can be assessed from both a…

Cusp overlap technique for transcatheter self-expanding aortic valve implantation

2021

Transcatheter aortic valve implantation (TAVI) may cause atrioventricular conduction disturbances and, consequently, the necessity for permanent pacemaker implantation (PPI). This is because the His bundle surfaces at the basal part of the membranous septum (in the neighbourhood of the non-coronary cusp) and implant depth greater than the length of the membranous septum may interfere with the conduction system [1]. To mitigate this risk, the valve should be implanted at a high position to minimize the contact of the valve frame with the base of membranous septum. During TAVI, the valve is usually positioned in a coplanar fluoroscopic projection with 3 cusps view, but for a self-expanding va…

Sex-based differences in outcomes with bivalirudin or unfractionated heparin for transcatheter aortic valve replacement: Results from the BRAVO-3 ran…

2016

Background Women comprise almost 50% of patients undergoing transcatheter aortic valve replacement (TAVR) and previous studies have indicated higher rates of procedural complications and bleeding in women compared to men. It is unknown whether men and women demonstrate a differential response to bivalirudin versus unfractionated heparin (UFH) in TAVR. We sought to evaluate outcomes by sex and type of anticoagulant from the Bivalirudin Versus Heparin Anticoagulation in Transcatheter Aortic Valve Replacement (BRAVO-3) trial of transfemoral TAVR. Methods BRAVO-3 was a randomized multicenter trial comparing transfemoral TAVR with bivalirudin versus UFH (31 centers, n = 802). The primary endpoin…
