Congenital left ventricular aneurysm (CVA) is a rare cardiac malformation. The prognosis is variable, depending on such factors as the size in comparison to the ventricular cavity, signs of heart failure, arrhythmia and so on. Most infants and young children with large aneurysm showed poor clinical outcomes. Here, we report ...

Sudden cardiac deaths are common within the community. They also constitute a substantial part of daily pathologic and forensic case work. However, macroscopic myocardial findings indicating acute ischemia are often absent. Then, diagnosis is based on coronary status in combination with indirect signs of acute cardiac failure. We present a ...

Cardiac troponins (cTn) are considered to be the 'gold standard' biomarker for the diagnosis of acute coronary syndrome (ACS); a pathological spectrum which includes cardiac ischemia, angina, myocardial infarction and ultimately cardiac failure. The growing evidence base for the diagnostic and prognostic use of cTn in ACS has resulted in ...

BACKGROUND: The electrocardiographic (ECG) diagnosis of left ventricular hypertrophy (LVH) is based on the assumption that QRS voltage increases with left ventricular mass. However, most of patients with echocardiographically detected LVH do not have increased QRS voltage. Reduced intercellular coupling has been observed in LVH patients and animal models. The ...

Symptomatic sustained cardiac arrhythmias are frequently observed in in the coronary care unit and often lead to hemodynamic compromise, especially in the presence of multisystem disease. The predominant arrhythmias noted in intensive care units are tachyarrhythmias, particularly atrial fibrillation and flutter, and ventricular tachycardia. Bradycardias, arguably less life-threatening than tachyarrhythmias, ...

BACKGROUND: Aortic valve replacement leads to improvement of coronary flow but not to complete normalization. Coronary hypoperfusion contributes to higher left ventricular mass persistence, arrhythmias, congestive heart failure and sudden death. This prospective study compares 2 similarly sized aortic prostheses (mechanical and porcine) regarding coronary flow and hemodynamic performances in ...

Although perioperative hypotension is a common problem, its true incidence is largely unknown. There is evidence that postoperative outcome, including the incidence of myocardial adverse events, may be linked to the prolonged episodes of perioperative hypotension. Despite this, there are very few comprehensive resources available in the literature regarding diagnosis ...
