PURPOSE The effects of aging on tissue strength and its ability to withstand forces associated with MRI have not been investigated. This study aimed to determine the forces required to cause partial or total detachment of a heart valve prosthesis in patients with age-related degenerative diseases exposed to MRI. METHODS Eighteen tissue samples excised during routine heart valve replacement su...
Percutaneous replacement of the aortic and pulmonic valves has rapidly gained acceptance in clinical practice as a feasible alternative to open valve surgery in patients deemed to be at high operative risk.1,2 Total percutaneous tricuspid valve replacement (TVR), on the other hand, has not yet been documented in humans, although this approach has been described in experimental animals.3 Webb et...
Organic disease of the tricuspid valve required surgery in 18% of all patients undergoing valve replacement over a five-year period. Differentiation of organic from functional disease is difficult and may be made only at open-heart surgery. The results of a series of 56 patients who underwent tricuspid valve replacement are presented; of these, 53 had organic disease. Operative mortality at the...
The acknowledgment of tricuspid regurgitation (TR) as a stand-alone and progressive entity, worsening the prognosis of patients whatever its aetiology, has led to renewed interest in the tricuspid-right ventricular complex. The tricuspid valve (TV) is a complex, dynamic and changing structure. As the TV is not easy to analyse, three-dimensional imaging, cardiac magnetic resonance imaging and co...
A 69-year-old woman with a history of surgical mitral valve repair for severe mitral regurgitation 12 years prior presented with a 6-month history of dyspnea on exertion (NYHA functional class II), exercise intolerance, and swelling of her abdomen and lower limbs. On jugular venous examination, giant systolic pulsations with prominent V-waves, known as the Lancisi sign or C-V waves, were noted ...
SUMMARY Echocardiographic studies were performed on six patients with autopsy-proved aortic atresia and hypoplastic left ventricle and two patients with surgically proved tricuspid atresia and hypoplastic right ventricle. The findings were compared to those from the echograms of 50 normal newborns who served as a control group. The ultrasound measurements obtained in the normal newborns were as...
Bicuspid aortic valve configuration and aortopathy pattern might represent different pathophysiologic sub-strates. A, Byers PH et al. The bicuspid aortic valve: an integrated phenotypic classification of leaflet morphology and aortic root shape. Association of Bicuspid aortic valve morphology and aortic root dimensions: a sub-study of the aortic stenosis progression observation measuring effect...
A 60-year-old, asymptomatic woman with no relevant cardiac history underwent 2-dimensional transthoracic echocardiography as part of a study protocol. The echocardiogram (Fig. 1) indicated the presence of a large mobile mass on the anterior leaflet of the tricuspid valve without notable regurgitation or obstruction. Electrocardiographic, chest radiographic, and laboratory values were within nor...
The tricuspid valve leaflets and their annular attachments were recorded by two-dimensional echocardiography from a view of the right ventricular inflow tract obtained by placing the transducer at an intermediate position between the left ventricular apex and the left lower sternal border. The transducer was rotated, and recordings were made at 30 degrees rotational intervals around the circumf...
From 1978 through 1987, 321 patients who had functional tricuspid regurgitation (TR) associated with mitral or combined mitral and aortic valve disease underwent tricuspid annuloplasty with our modification of the original De Vega's annuloplasty technique. The modified De Vega's annuloplasty consisted of two separate semicircular sutures placed around the anterior and lateral aspect of the tric...
