DOI: 10.5935/abc.20160073 A 47-year-old male presented with a subacute inferior myocardial infarction (MI) complicated by inferobasal ventricular septal rupture (VSR) and underwent emergency surgical repair of VSR with a pericardial patch. In the postoperative period he remained hypotensive, with low exercise tolerance and a holosystolic murmur was present. Echocardiography showed persistence o...

BACKGROUND Ischemic mitral regurgitation indicates a poor prognosis after acute myocardial infarction (AMI). This study addresses the clinical characteristics and contribution of ischemic mitral regurgitation to the midterm survival rate of patients following first AMI in our institution. METHODS Between January 2000 and December 2002, patients who underwent 2-dimensional color Doppler echoca...

In the present multiple case study, we examined hemodynamic changes in the brain in response to motor execution (ME) and motor imagery (MI) of swallowing in dysphagia patients compared to healthy matched controls using near-infrared spectroscopy (NIRS). Two stroke patients with cerebral lesions in the right hemisphere, two stroke patients with lesions in the brainstem, and two neurologically he...

BACKGROUND To describe the rare finding of a double massa intermedia (MI). Typically, the MI (interthalamic adhesion) is a single bridge of gray matter connecting the medial surfaces of the thalami. METHODS Twelve formalin- and alcohol-fixed human third ventricles were examined from superior to inferior by fiber dissection technique under ×6 to ×40 magnifications and with the endoscope. RES...

background: moderate non-organic tricuspid regurgitation (tr) concomitant with coronary artery disease is not uncommon. whether or not tr improves after pure coronary artery bypass grafting (cabg), however, is unclear.   the aim of this study was to evaluate the effect of isolated cabg on moderate non-organic tr. methods: this study recruited 50 patients (40% female, mean age: 65.38 ± 8.01 year...

the most common cardiovascular surgery in the world and iran as well, is cabg. one of the most important post-operative complication of this operation, that increase morbidity and mortality, is peri-operative mi. incidence of peri-operative mi in cabg operations is between 2.5 to 5.5%. in this study we determined the prevalence and incremental risk factors of peri-operative mi in 300 consequati...

Soft-tissue attenuation artifacts generally appear as fixed perfusion-scan defects. Gated 99mTc-tetrofosmin SPECT may help differentiate myocardial infarction (MI) from artifacts, as fixed defects with decreased function (wall motion and thickening) probably represent MI, whereas attenuation artifacts represent preserved function. Methods: Ungated stress and gated rest 99mTc-tetrofosmin SPECT w...

OBJECTIVE To evaluate the incidence and prevalence of left ventricular (LV) dyssynchrony in patients with heart failure after myocardial infarction (MI) by real- time three-dimensional echocardiography (RT-3DE), and to investigate the clinical application value of using RT-3DE as a method of providing more detailed information for clinical strategy. METHODS This cross-sectional study was carr...

OBJECTIVES To analyze and compare quantitatively regional myocardial functional abnormalities of the left ventricle by pulsed Doppler tissue imaging (DTI) in patients with unstable angina (UA) and prior myocardial infarction (MI), and to explore the value of systolic velocity and time intervals in evaluating regional left ventricular systolic dysfunction. METHODS Patients with coronary artery...
