Imaging of left main coronary artery dissection with multislice computed tomography.

We occurred in a left main (LM) dissection during primary coronary intervention in a 45-year-old man with anterior acute myocardial infarction. Successful, multiple direct stenting was performed from the ostial to the mid left anterior descending coronary artery (LAD). Nonetheless, an LM dissection involving the proximal circumflex artery (Cx) was still evident at the end of the intervention. Multislice Computed Tomography (MSCT) coronary angiography images showed that LM dissection was definitely long and close to the ostium; moreover, the proximal stent had both excluded the false lumen in the LAD and stabilized the dissection towards the Cx. Two months later, at MSCT coronary angiography the LM dissection was still evident and the patient had remained totally asymptomatic. MSCT coronary angiography can be recommended as a complementary diagnostic tool for the assessment of LM anatomy because of the possibility of three-dimensional reconstructions and consequent clear evaluation of its take-off, course and bifurcation.

Myocardial ischemia due to a coronary-to-pulmonary artery fistula proximal to an intermediate stenosis in the left anterior descending coronary artery: percutaneous closure by means of angioplasty and stent grafting.

This case report refers to a 46-year-old patient with symptomatic stable angina and myocardial ischemia documented at 99mTc-MIBI SPECT scintigraphy. Coronary angiography revealed a coronary artery fistula (CAF) and a non-significant stenosis of the left anterior descending coronary artery (LAD). We performed coronary angioplasty and stenting of the LAD and closure of the CAF using a covered stent. After the procedure the patient was asymptomatic and a myocardial scintigraphy, performed 6 months later, confirmed the absence of myocardial ischemia. This suggests that a CAF arising before a coronary stenosis may contribute to the genesis of myocardial ischemia, perhaps by giving rise to a steal phenomenon.

Anatomical M-mode: an old-new technique.

The M-mode (motion mode) technique has improved the diagnostic possibilities of echocardiography due to its high temporal resolution. The use of a two-dimensional (2D) image as a basis for M-mode analysis at a defined line, independent of the transducer orientation, namely the anatomic M-mode (AMM), has been proposed from the beginning of 2D echocardiography. For several years, however, this could not be accomplished due to several reasons including the limited digital memory, the relatively rough pixels of 2D images, and the low temporal resolution of the screen. The AMM has been improved by the "fully digital" machines. These are able to provide a series of digital data (direction, position, and timing) relative to any single echo received from any point of the tissue. AMM analysis, thus, can be performed in any direction, as a "normal" monodimensional echocardiogram. With respect to traditional M-mode, AMM permits a more detailed analysis of cardiac chambers diameters obtained by linear measurements, regional wall motion of the left ventricle (both at rest and during stress), and location of accessory pathways. In particular, the assessment of left ventricular regional wall motion represents the most important goal of this new technique, which results in marked reduction or even elimination of the limitations due to the subjective character of wall motion evaluation with 2D echocardiography.
