A study was performed to evaluate the changes of cardiac dimension in 73 patients with infarction and 72 persons (control) without cardiovascular diseases or diseases that influence the cardiovascular system by ultrasound. Results showed that the infarction caused a dilatation of left ventricle and atrium, increasing of volume of the left ventricle in both systolic and diastolic phases. Patients with grade II cardiac failure as killip had dilatation of the left ventricle was more than this in patients with grade I cardiac failure.

Among 112 patients after myocardial infarction (MI), males account for 94.6% with mean age is 66.47.4 years old. Most of them have complicated ventricular arrhythmia. The grade IV and V of ventricular arrhythmia on Lown classification relate strongly to the increase in left ventricular diameter, volume, weight and muscular mass and to the decrease in left ventricular systolic function. Increasing in left ventricular size (Dd 52mm, Ds 35mm, EDV 125ml, ESV 50ml), left ventricular hypertrophy (LVMI = 130g/m2), decreasing in blood ejective fraction (EF=40%) and ventricular wall distension all increase the risk of complicated and ventricular arrhythmia and grade III, IV and V of this condition according to Lown classification

The research was carried out on 140 patients with previous myocardial infarction and history of typical myocardial infarction, currently with the signs of the previous myocardial infarction by electrocardiogram and the group control of 55 healthy people. Results: the heart beat in the group control and group patient were 73,2+/- 11 and 74,6 +/- 12,7 respectively; the systolic blood pressure in the group control and patients were 77,9+/- 6,4 and 77,8+/- 8,6; respectively. The left ventricular internal dimension and diastole in patients was 61,2+/- 5,6 (mm), the left ventricular length diastolic was 87,9+/-11,3 (mm); the left ventricular area diastole was 44,7+/-10.99 (cm3); the end diastolic volume was 197,1+/- 74,8 (ml). The extend of the left ventricular expansion was direct provisional with the cardiac failure grade and position of the deep septal myocardial infarction.

We report here on one patient who suffered from acute myocardial infarction that was due to late stent thrombosis, and this was associated with late stent malapposition very late (21 months) after the deployment of a paclitaxel-eluting stent and shortly after (7 days) the discontinuation of the aspirin therapy. The intravascular ultrasound examination revealed that the late stent thrombosis was accompanied by late stent malapposition. This is a report on late stent thrombosis associated with late stent malapposition after the successful implantation of a paclitaxel-eluting stent (PES).

An intramural hematoma is a rare, challenging cause of myocardial infarction generally seen in middle-aged females with no atherosclerotic risk factors. Intravascular ultrasound is useful in diagnosing and managing intramural hematomas. Here, we present anintramural hematoma presenting with ST-elevation myocardial infarction without definite intimal dissection in an elderly man who was diagnosed using intravascular ultrasound and managed accordingly.

Testicular infarction is caused most commonly by acute testicular torsion, but rarely by epididymitis. We report color Doppler sonographic findings and Doppler spectrum in a 56-year-old man with epididymitis that was complicated by testicular infarction.

Transesophageal echocardiography was performed to evaluate the exact cause of severe mitral regurgitation in a 64-year-old man presented with hypotension and dyspnea after acute inferior wall myocardial infarction. In mid-esophageal two-and four-chamber view, the ruptured stump of papillary muscle could not be visualized. However, in transgastric two-chamber view, we could clearly visualize the ruptured head of the posteromedial papillary muscle as a separated mass attached by chorda tendinae, as well as the freely mobile stump of the ruptured papillary muscle within the left ventricle. So, the comprehensive transesophageal echocardiography, including transgastric imaging, is always indicated in patients with severe mitral regurgitation after acute myocardial infarction.

Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome and sudden cardiac death. The incidence, causes, pathogenesis, and treatment have not been defined clearly, but spontaneous coronary artery dissection should be considered in young patients without major cardiovascular risk factors or in patients in the peripartum period who present with acute coronary syndrome. The treatment is often challenging. Medical treatment is usually considered, and percutaneous coronary intervention or coronary artery bypass surgery may be possible in some patients. We herein report two cases of middle-aged males with myocardial infarction who were treated with percutaneous coronary angioplasty.

BACKGROUND: Plaque rupture of the atherosclerotic plaque is an important pathophysiologic mechanism of acute coronary syndrorne(acute myocardial infarction or unstable angina). Plaque rupture and resulting thrombus formation could be identified by intravascular ultrasound (IVUS), even though the sensitivity was variable in previous reports. We sought to know the morphologic characteristics, incidence of plaque rupture and thrombus formation by ultrasound in patients with acute coronary syndrome. METHOD: Between April and Septernber 1997, 23 admitted patients who was diagnosed as unstable angina or acute rnyocardial infarction was included. We performed coronary angiography with IVUS examination within 2 weeks. Atherosclerotic plaque was classified into soft, fibrous, calcific, and mixed plaque, and plaque rupture was defined as rupture of fibrous cap with discontinuity and / or backflow into plaque. Thrombus was defined as a scintillating, movable mass or layering materials that could be distinguished from underlying plaque. RESULTS: Most of the plaques were soft and mixed types(14 and 6, out of 23 cases). Plaque rupture could be identified only in small portion(6 cases, 26%) of the cases. Thrombus was noted in 12 cases(52%). 4 cases showed both plaque rupture and thrombus. CONCLUSION: Soft plaque is the most frequent plaque pye in acute coronary syndrome. IVUS is a useful tool to identify the morphologic features of the plaque such as rupture and thrombus formation.
