“…Valvular regurgitation with a colour jet shorter then 1 cm, no mosaic colour jet, and a colour jet identified in only one plane were graded as trivial. On the other hand, the severity of pathologic valve regurgitation was graded qualitatively from 1 (mild) to 4 (severe) [3,11].…”

We aimed to evaluate the predictors of the severity of chronic rheumatic valvar disease. The long term follow-up records of 139 patients with chronic rheumatic carditis were reviewed. Children were followed-up on an outpatient basis for a period ranging from 1-16 years (5.0 +/- 3.7 years). Mitral regurgitation either isolated (51%, n=71) or combined with aortic regurgitation (AR) (49%, n=68) was observed in all cases of the initial attack of rheumatic carditis. AR at initial attack of the rheumatic carditis was found to be affected by gender (AR was more associated with males, p = 0.032), combined mitral and aortic regurgitation (CMAR), and presence of MR at initial attack (p = 0.000 and p = 0.012, respectively) with univariate analysis. The effect of CMAR on AR at initial attack was also significant by multivariate analysis (p = 0.000). CMAR, MR, and AR at initial attack had significant effects on CMAR at final evaluation (p = 0.000, p = 0.020, and p = 0.000, respectively) in univariate analysis. Multivariate analysis revealed the significant effects of CMAR and MR at initial attack on CMAR at final evaluation (p = 0.000 and p = 0.005, respectively). Univariate analysis showed that MR and AR at initial attack, and CMAR at final evaluation, had significant effects on MR at final evaluation (p = 0.000, p = 0.029, and p = 0.000, respectively). MR at initial attack and CMAR at final evaluation had significant effects on MR at final evaluation with multivariate analysis (p = 0.001 and p = 0.003, respectively). AR at final evaluation was affected by CMAR and AR at initial attack (p = 0.000 and p = 0.000, respectively), and CMAR and MR at final evaluation (p = 0.000 and p = 0.000, respectively) with both univariate and multivariate analysis. Mitral valve prolapsus was more common in patients with a longer duration (37.5%, 6 out of 16) than those with a shorter duration (11%, 14 out of 123) and the difference was significant (p = 0.020). In conclusion, the initial severity of valve involvement and the presence of CMAR at initial attack were found to be the best predictors for the severity of chronic rheumatic valvar disease in this study.

“…Individual II-6 had a septal bulge in LVOT and mild AR recorded by Doppler echocardiography. It is not likely that the observed AR caused the very localized hypertrophy, as only severe AR is known to cause global hypertrophy of the left ventricle (22). In addition, individual II-6 is the father of a child (III-5) fulfilling major FHC criteria, making him an obligate carrier of the disease gene.…”

The aim of this study was to determine the relative value of clinical, échocardiographie, Doppler, and catheterization examinations in recognizing the presence and estimating the severity of acute aortic regurgitation in critically ill patients. Retrospective analyses of clinical, échocardiographie, Doppler, and cardiac catheterization data were performed. Twenty-four acutely ill patients with echo-Doppler evidence of acute severe aortic regurgitation who either underwent aortic valve replacement (n = 21) or died and had autopsies (n = 3) were studied. Clinically, acute severe regurgitation was diagnosed in the presence of an early diastolic murmur accompanied by tachypnea, tachycardia, and bilateral basilar rales. By echo-Doppler, acute severe aortic regurgitation was diagnosed in the presence of early closure of the mitral valve on the M-mode echocardiogram and an aortic regurgitation velocity half-time < 280 ms by continuous-wave Doppler ultrasound. The sensitivity of the clinical findings and noninvasive studies was assessed against invasive estimates of regurgitation severity by aortography in 12 patients and ventricular sump flow at the time of aortic valve replacement in 21 patients. By clinical examination, aortic regurgitation was detected in 18 (75%) patients, but was considered severe in only 12 (50%). M-mode echocardiography detected the presence of aortic regurgitation in 12 patients, but premature closure of the mitral valve was seen in only 6 (25%). Doppler studies detected the presence of aortic regurgitation in all 24 patients, and Doppler half-time <280 ms accurately predicted aortic regurgitation severity in all but 2 patients. The latter 2 patients had a markedly elevated left ventricular end-diastolic pressure and a moderately severe rather than a severe aortic regurgitation by aortography. Aortography added little to the information already obtained by Doppler studies. Two patients died while waiting for aortography. Coronary angiography detected associated coronary artery disease in 3 of the 12 patients. Clinically, it is difficult to evaluate the severity of acute aortic regurgitation in the critically ill. The continuous-wave Doppler half-time method permits noninvasive, rapid detection and accurate estimation of aortic regurgitation severity. Cardiac catheterization is recommended only when the noninvasive evaluation is inconclusive or evaluation of the coronary anatomy is indicated.
