Rv Lv Ratio Pe

Figure 3 kaplan meier survival estimates of patients with ild stratified according to rv lv ratio using the rv lvlargest method.

Rv lv ratio pe. If these five factors were all absent 37 1 of the population the probability that ct rv lv ratio is sufficient to exclude rv strain pe related short term death was 0 97 95 ci 0 95 0 99. There was one major bleed which was a groin hematoma that resulted in transient hypotension. Primary outcome was rv lv ratio at 48hrs. The normal ratio of right to left ventricular size is generally quoted as 0 6 with a ratio of 1 0 considered to be significant right ventricular enlargement.

Positive study rv dilation 1 1 ratio. Single arm prospective trial of treatment of acute pe 31 massive pe 119 submassive pe. This study found that compared with the gold standard transthoracic echo tte ct sensitivity for rv strain was 88 specificity 39 ppv 49 and npv 83. In the study by araoz et al 42 an rv lv diameter ratio greater than 1 was associated with a 3 6 fold increased risk of admission to the intensive care unit.

Normal ct rv lv ratio plus readily obtained five clinical predictors were adequate to exclude rv strain or pe related short term mortality. Sensitivity 50 specificity 98 ppv 88 npv 88. An rv lvlargest ratio 1 0 was an adverse predictor of mortality. This is not specific to pe as other conditions including copd congenital anomalies and primary pulmonary hypertension may also cause rv enlargement.

Rv lv ratio 1 0 n 13 and rv lv ratio 1 0 n 79. Treatment decreased rv dilatation and pulmonary hypertension with zero cases of ich. In this patient level post hoc analysis of 2 dutch clinical trials hestia. Rv lv ratio 0 9 rv strain ct pulmonary angiogram ctpa can not only visualize the clot but can also detect evidence of rv strain.

Additional studies have estimated that an rv lv diameter ratio superior to 1 5 indicates a severe episode of pe 36 39 41. All patients with a mcconnell s sign were positive for pe.
