A 76-year-old man with a history of chronic mitral regurgitation presented with symptoms of progressive heart failure. The chest radiograph (Fig. 1A) showed severe cardiomegaly (arrows), with a cardiothoracic index (CTI) > 0.7. Echocardiography (Fig. 1B) demonstrated severe biatrial dilatation, severe mitral regurgitation consistent with rheumatic valve disease, and moderate aortic and tricuspi...
Relevant secondary mitral regurgitation occurs in 35– 50% of patients with chronic heart failure and is associated with increased mortality. Surgical management of patients with mitral valve regurgitation and heart failure remains controversial. There are several questions which are not sufficiently clarified because of a lack of prospective randomised controlled trials: (1.) The indication for...
SUMMARY To test the hypothesis that the fall in supravalvular aortic diastolic pressure is relative to the severity of the regurgitant flow in aortic regurgitation, 27 patients with isolated aortic regurgitation, 23 patients with combined aortic regurgitation and stenosis, and 15 normal subjects were studied. Diastolic pulse pressure (pressure at the dicrotic notch minus pressure at end diastol...
7. Clinical bottom line TV insufficiency should be treated during left-sided valve surgery when TR annulus is dilated (G21 mmym ;)70 mm 2 intra-operatively; G3.5 cm at trans-thoracic echocardio-graphy (TTE) w18x) regardless of the absolute grade of regurgitation, in cases of preoperative AF, trans-tricuspid PMK lead and underlying rheumatic disease. Also, 'ring' annuloplasty techniques should b...
BACKGROUND This study was designed to evaluate the incidence and mechanisms of mitral regurgitation following mitral balloon valvotomy (MBV) in 40 consecutive patients with symptomatic tight pliable mitral stenosis. METHODS AND RESULTS Transthoracic echocardiography with color flow mapping was performed before and 24 hours after the procedure. Patients who developed significant mitral regurgi...
Hemodynamic deterioration because of worsening of mitral regurgitation can occur in a small number of patients undergoing atrioventricular node (AVN) ablation and pacing therapy. Patients with moderate mitral regurgitation before ablation seem prone to this complication. Successful permanent His-bundle pacing after AVN ablation was performed in a patient with chronic atrial fibrillation and mod...
A 14 year old girl presented with severe tricuspid regurgitation after she was diagnosed with "transient tricuspid regurgitation of the newborn". In the neonatal period she had presented with severe tricuspid regurgitation without an obvious underlying anatomical cause. This spontaneously regressed during the first months of life. She was dismissed from follow up at the age of 5 years after com...
Tricuspid valve regurgitation was assessed quantitatively by measuring blood flow velocity in the vena cava using a pulsed Doppler velocimeter. A non-invasive index of regurgitation was obtained by calculating the ratio between the maximum amplitudes of the systolic and diastolic components of the velocity curves. The index was compared with the angiographic grading of regurgitation in 70 patie...
Sixty patients with pulmonary regurgitation were studied by the pulsed Doppler technique combined with two-dimensional and M-mode echocardiography. Patients with pulmonary regurgitation had abnormal Doppler signals just below the pulmonic valve in the right ventricular outflow tract in diastole on the two-dimensional image. These signals were considered to indicate the regurgitant flow. There a...
Traumatic tricuspid regurgitation is a rare complication of blunt chest trauma. With the increase in the number of automobile accidents, traumatic tricuspid regurgitation has become an important problem after blunt chest trauma. It has been reported more frequently because of better diagnostic procedures and a better understanding of the pathology. The early diagnosis of traumatic tricuspid reg...
