Left-ventricular shape determines intramyocardial mechanical heterogeneity.
Left-ventricular remodeling is considered to be an important mechanism of disease progression leading to mechanical dysfunction of the heart. However, the interaction between the physiological changes in the remodeling process and the associated mechanical dysfunction is still poorly understood. Clinically, it has been observed that the left ventricle often undergoes large shape changes, but th...
متن کاملIntramyocardial pressure and strength of left ventricular contraction.
• Earlier experiments 1>2 suggested that the contractile strength of the cardiac ventricles might be determined by the pressure in the coronaiy arteries and not by the quantity of metabolites supplied to the heart muscle or by presystolic factors. In further investigations (reported here in section II), we confirmed this hypothesis: coronary perfusion pressure influenced ventricular contractile...
متن کاملDissecting intramyocardial haematoma diagnosed by contrast echocardiography.
Intramyocardial dissecting haematoma is a rare form of cardiac rupture that can occur as a complication following acute myocardial infarction or during the remodelling process. It is usually caused by a haemorrhagic dissection among the spiral myocardial fibres and needs urgent surgical treatment. Here we report the case of a 67-year-old man with indications of a previous infarction, in whom a ...
متن کاملEarly Spontaneous Remission of Intramyocardial Dissecting Hematoma
Intramyocardial dissecting hematoma is a rare but potentially fatal complication of myocardial infarction. The decision to adopt a surgical or conservative strategy may depend on the clinical and hemodynamic stability of patients. Regardless, the precise and temporal assessment of the structure of hematoma is imperative. We herein report the first case of a patient with early spontaneous remiss...
متن کاملMultimodality imaging of a dissecting intramyocardial hematoma extending into the left atrial wall following myocardial infarction.
Five days after the onset of substernal chest pain, a 60-year-old man with a history of hypertension, smoking (60 pack-years), severe bullous emphysema, and epilepsy presented with acutely worsening chest pain. Pharmacological management for non–ST-segment elevation myocardial infarction was initiated based on 12-lead ECG findings of subtle anterolateral ST segment changes (V2–V5) and a troponi...
