Different aspects of coronary microvascular damage during reperfusion of ST-elevation acute myocardial infarction
No full textThe beneficial effects of a timely recanalisation of the infarct-related coronary artery in ST-elevation myocardial infarction may be limited at the microvascular level by reperfusion injury and distal microembolisation. These complications carry ominous consequences for both prognosis and survival. The importance of reperfusion injury and microembolisation has been progressively more recognized and many different preventive and therapeutic interventions have been developed to minimise these complications. In the present contribution some simple elements of value in the understanding, recognition and differential diagnosis of reperfusion injury and coronary microembolisation are provide
Late mitral annuloplasty failure: the loss of the ring.
No full textAbstract
An 81-year-old man complained with increasing dyspnoea and asthenia few months after a successful double mitral and tricuspid valvuloplasty intervention. The echocardiogram revealed a partial detachment of the mitral annuloplasty ring due to dehiscence determining a severe regurgitation. Curiously, at Color-Doppler analysis of mitral inflow, the prolapse of the detached ring produced a fascinating circular line inside the regurgitation signal, mimicking the shape of a gemstone ring. We described a case of a relatively uncommon cause of late mitral valvuloplasty failure characterized by a really unusual echocardiographic finding
Real-time imaging of dissection of the ascending aorta.
No full textAbstract
We report the case of a 72-year-old woman referred for evaluation of a chest and back pain in whom we documented the dramatic progression from intramural hematoma to dissection of the ascending aorta with cardiac tamponade
Echocardiography in the assessment of left ventricular longitudinal systolic function: current methodology and clinical applications.
No full textAbstract
Quantification of left ventricular (LV) systolic function represents a major aspect of echocardiographic assessment in the spectrum of cardiac diseases. However, because of the high complexity of LV contraction mechanics, the classical approach with assessment of a single measure of systolic function, such as ejection fraction or fractional shortening, has been largely superseded. During the last years, through the considerable technical advances in the field of ultrasonography, a number of different echocardiographic methodologies have become available to perform a detailed assessment of different aspects of LV contraction. In particular, evaluation of LV longitudinal systolic dynamics has progressively gained importance as a key aspect in the assessment of LV systolic function. For most of the techniques currently used to explore LV longitudinal function, the clinical usefulness in both research and daily practice has been validated by consistent evidence and their use is rapidly increasing. Technical considerations and potential clinical applications of the assessment of LV longitudinal systolic function are reviewed

How should I treat pulmonary arteriovenous malformations in a patient with Rendu-Osler disease presenting with transient ischaemic attack
No full textAbstract
BACKGROUND: A 42-year-old man with no cardiovascular risk factors or history was admitted for evaluation of an episode of transient ischaemic attack (TIA). He had no cardiovascular risk factors and his physical examination was unremarkable. INVESTIGATION: Physical examination, electrography, transesophageal echocardiogram, coronary angiogram. DIAGNOSIS: Intrapulmonary shunting, in the presence of arteriovenous malformations, possible hereditary haemorrhagic telangectasia. TREATMENT: Transcatheter occlusion of multiple pulmonary arteriovenous malformations using an AMPLATZER vascular plu
Early cardiac remodeling after repair of sinus venosus atrial septal defect
No full textWe report the case of a 24-year-old man who underwent surgical repair of a sinus venosus atrial septal defect. Transthoracic echocardiograms performed on Day 3 and 6 after surgery demonstrated a very early cardiac remodeling with dramatic reduction of the right ventricular and atrial dimensions paralleled by an increase in the size of the left ventricle. This case provides the first demonstration of a very early cardiac remodeling after repair of sinus venosus atrial septal defect
