ABSTRACT

The authors report the case of a young patient with an aneurysm of the ascending aorta and moderate aortic incompetence, who underwent a conservative operation at our institution. Dilatation of the sinotubular junction, particularly at the level of the non-coronary sinus of the aortic valve with loss of coaptation between the corresponding leaflet and the two coronary leaflets, was identified at the time of surgery as major cause of valve insufficiency. During surgery, the dilated ascending aorta and pathologic aortic sinus were replaced with a 26 Hemashield prosthesis tailored according to the David guidelines. An intraoperative post-repair transesophageal echo exam showed that the aortic valve appeared to be working competently. The post-operative course was uneventful and at one year, an echographic check of the aortic valve showed that it was fully competent, with normal leaflet motion. Conservative surgery can be a good option in selected patients with ascending aortic aneurysm and aortic valve insufficiency.

ABSTRACT

Mental stress testing can induce ischemia in coronary patients, but often may not induce chest pain and/or electrocardiographic changes. Therefore, we tested the utility of echocardiography to increase the sensitivity of the method. For this purpose, 56 patients undertook arithmetic mental stress tests and then were subjected to coronary angiography. During the test we evaluated left ventricular function, electrocardiography results, and emotional involvement measured by STAI (State Trait Anxiety Inventory). Echocardiography was positive in 21 patients, and electrocardiogram only in 2 patients. No patient complained of chest pain. The remaining 35 patients were negative. Comparing echo data with coronary angiography, in all the cases, sensitivity was 73.5%, specificity 93.3%. Analysis of the STAI revealed that the negative test we observed could be due to a low stressor efficacy. In conclusion, echocardiography in mental stress testing permits improved sensitivity, with loss of specificity in comparison with conventional electrocardiographic monitoring.
