AORTA INDICATOR 1.1|醫療線上App不用買-HotApp4Game

The application "AORTA INDICATOR 1.0", which is based on well-defined parameters, calculates automatically:

The Body Surface Area (BSA) with the parameters indicated by both Mosteller and Dubois.

The prediction of the aortic diameter at the level of the Valsalva's sinuses, supraaortic ridge, ascending aorta and descending aorta.

The Aortic Ratio.

The Critical Aortic Size.

The Aortic Size Index.

The Z-Score.

The application is constituted as follows:

1. PATIENT DATA. On this page, the following information must be provided: the patient's data, age, weight, height, gender, actual aortic diameters (according to Roman's instructions): the Body Surface Area (BSA) is calculated automatically according to Mosteller's and Dubois formula, then the following data are to be inserted: "Associated Condition": Marfan's syndrome, Bicuspid Aortic Valve, Aortic Valve Surgery, Connective tissue Disorder, Family history of aortic dissection, Hypertension, Progressive aortic growth, Patient is pregnant, Surgeon experience (selecting "surgeon experience" will furnish a short description on the meaning of the term).

2. Selecting OK will take you to the second page ("RESULTS"), which is subdivided into three sections:

1. In the first section, Prediction of the Aorta Diameter, the following elements are calculated: the theoretical aortic diameters according to the Roman, Biaggi and Hannuksela models. The Framighan study is likewise calculated for the Valsalva sinuses, for the ascending sinus-tubular-aortic junction and for the descending thoracic aorta.

2. In the second section, "Surgery Indications", the following parameters are calculated: Aortic ratio for the diameters at the Valsalva sinuses (these value must be related to their specific context). Based on the elaborated response, one of the following indications will appear: "Provide Operative Treatment" or "follow-up". If in the section labelled "Associated Conditions", "Bicuspid Aortic Valve (BAV) and/or "Marfan's syndrome" were selected, the "Z-Score" will also appear.

3. Critical Aortic Size: in this section, the maximum theoretical aortic diameters are calculated and displayed. As above, the display may indicate either the recommendation to seek "Operative Treatment" or "Follow-up".

4. Aortic Size Index: it is the ratio between the actual aortic diameter and the BSA. Davies subdivides them into three risk categories:

1. Low Risk (4% yearly rupture).

2. Moderate Risk (8% yearly rupture) .

3. Severe Risk (20-25% yearly rupture) .

4. Should the calculated risk fall within the "moderate" to "severe" risk range, the recommendation will be for "Provide Operative Treatment"; in the event of a low risk calculation, recommendation will be for a "Follow-up".

5. Patients with Bav or Marfan's Syndrome: If in the sections "Associated Conditions" the parameters "Bicuspid Aortic Valve (BAV) or Marfan's Syndrom were selected, and the "critical aortic size index" is above the value of 10 cm2/m, the display will indicate "Provide Operative Treatment".

3. The third section reports the recommendations as indicated in the "OFFICIAL GUIDELINES 2010".

The application is free and it is currently available for all Android operative systems. All the bibliography references and the authors names can be visualized on your smartphone through the menu key.
