conclusions chronic smoking caused left ventricular diastolic dysfunction. acute intake caused left and right ventricular diastolic dysfunction. changes persisted up to 30 minutes after smoking, although diastolic blood pressure returned to normal state. objectives the current study aimed to evaluate the acute and chronic effects of smoking on the left and right ventricular (rv) diastolic funct...

conclusions despite the widespread use of 2d lvef and its good agreement with ventriculography, strain analysis seems to be more reliable as a quantitative tool for ventricular assessment. results the lvef values obtained by the two methods of ventriculography and echocardiography were not significantly different. the highest correlation regarding the echocardiographic lvef was obtained in the ...

Isolated noncompaction of left ventricular myocardium is a rare disorder of endomyocardial morphogenesis characterized by numerous, excessively prominent ventricular trabeculations and deep intertrabecular recesses. This study comprised eight cases, including three at necropsy. Ages ranged from 11 months to 22.5 years, with follow-up as long as 5 years. Gross morphological severity ranged from ...

Delayed improvement of left ventricular contractile function in the setting of acute ischemia followed by reperfusion ("stunned myocardium") has been observed in a number of clinical scenarios, and may have important clinical implications. At present, there are no widely accepted techniques available to demonstrate its presence. We report a case in which a rest 99mTc-sestamibi scan performed 12...

A62-year-old woman with a history of vasospastic angina presented to the emergency room with chest pain. The ECG showed ST-segment elevation in leads V3 through V6. The transthoracic echocardiogram revealed an akinetic left ventricular (LV) apical wall. The coronary angiogram on admission demonstrated normal coronary arteries. Two weeks later, resting Tc-tetrofosmin myocardial single photon emi...

BACKGROUND Noncompaction of the left ventricular myocardium is recently described as a cause of left ventricular dysfunction. In the article, we describe epidemiological and clinical aspects of this condition, which presents clinically at any age. MATERIAL AND METHODS This article is based on a review of articles from our own literature archive and relevant references in these articles. RES...

Noncompaction of the ventricular myocardium is a rare cardiomyopathy due to an arrest of myocardial morphogenesis. The characteristic echocardiographic findings are prominent myocardial trabeculations and deep intertrabecular spaces communicating with the left ventricular cavity. The clinical manifestations include heart failure (HF) signs, ventricular arrhythmias, and cardioembolic events. We ...

The "left ventricular mass" (LVM) using Tc-99m Sestamibi SPECT imaging may be a useful parameter to quantitatively assess the left ventricle and hence its function. The LVM was determined without reorienting the images along the long axis of the left ventricle. A comparison with reoriented SPECT images was then performed. The LVM showed the expected variations among different pathological heart...

experimental and clinical studies have shown that intracoronary transplantation of autologous bone marrow mesenchymal stem cells (bmscs) has resulted in regenerated infarcted myocardium and improved left ventricular (lv) function.the aim of this pilot study was to assess the benefical effectsof intracoronary transplantation of bmsc in patients with oldmyocardial infarction (omi). autologous bms...

Amyloid cardiomyopathy is characterized by non-dilated thick-walled left ventricular, thickening of interventricular septum and right ventricular free wall, biatrial enlargement associated with granular 'sparkling' appearance of the myocardium. Typically, decreased left ventricular compliance results in abnormal diastolic functions but left ventricular systolic functions are preserved until lat...
