Morbidly obese patients are at risk for diastolic cardiac dysfunction, which can lead to adverse event, such as, diastolic heart failure postoperatively. Preoperative screening by transthoracic echocardiogram is difficult due to anatomical challenge, therefore the prevalence of this problem may be underestimated. The investigator would like to perform transesophageal echocardiogram in this group of patients after anesthesia induction to demonstrate the true prevalence of this syndrome.
Morbidly obese patients are at risk for both respiratory and cardiovascular abnormalities. Many cardiac problems were previously reported including left ventricular hypertrophy, right and left ventricular systolic dysfunction etc. Diastolic cardiac dysfunction can be found in normal left ventricular systolic function and can lead to diastolic heart failure postoperatively.
Preoperative screening by transthoracic echocardiogram is difficult due to anatomical challenge (thick chest wall, narrowing of inter-rib space), therefore the prevalence of this problem may be underestimated. Transesophageal echocardiogram provides better cardiac view, but requires sedation during procedure. So, it is not practical for out-patient setting. The investigator would like to perform transesophageal echocardiogram in this group of patients after anesthesia induction to demonstrate the true prevalence of this syndrome.

In this study ASA 1, 2 individuals with grade 1 or 2 diastolic dysfunction will be recruited to assess the effects of Remifentanil infusion on left ventricular function evaluated with tran...
Diastolic dysfunction is a key factor in the pathogenesis of heart failure. Around 50% of cases of heart failure, the hemodynamic correlate of which is increased left ventricular filling pressure, are...
Intraventricular velocity distribution reflects left ventricular (LV) diastolic function and can be measured non-invasively by flow mapping technologies. We designed our study to compare intraventricu...
Computed tomography (CT) is an important imaging modality in diagnosing a variety of disorders. Although systolic heart failure is a well-known risk factor for postcontrast acute kidney injury (PC-AKI...

This study determined the effects of doxorubicin and/or trastuzumab on diastolic function and the relationship between diastolic function and systolic dysfunction.
A condition of markedly elevated BLOOD PRESSURE with DIASTOLIC PRESSURE usually greater than 120 mm Hg. Malignant hypertension is characterized by widespread vascular damage, PAPILLEDEMA, retinopathy, HYPERTENSIVE ENCEPHALOPATHY, and renal dysfunction.
The inability in the male to have a PENILE ERECTION due to psychological or organ dysfunction.
General dysfunction of an organ occurring immediately following its transplantation. The term most frequently refers to renal dysfunction following KIDNEY TRANSPLANTATION.
A rare autosomal recessive disease characterized by the deposition of copper in the BRAIN; LIVER; CORNEA; and other organs. It is caused by defects in the ATP7B gene encoding copper-transporting ATPase 2 (EC 22.214.171.124), also known as the Wilson disease protein. The overload of copper inevitably leads to progressive liver and neurological dysfunction such as LIVER CIRRHOSIS; TREMOR; ATAXIA and intellectual deterioration. Hepatic dysfunction may precede neurologic dysfunction by several years.
A form of ischemia-reperfusion injury occurring in the early period following transplantation. Significant pathophysiological changes in MITOCHONDRIA are the main cause of the dysfunction. It is most often seen in the transplanted lung, liver, or kidney and can lead to GRAFT REJECTION.
Obesity is the condition in which excess fat has accumulated in the body (mostly in subcutaneous tissues). clinical obesity is considered to be present when a person has a BMI of over 30 (Oxford Dictionary of Medicine). It is becoming increasing common i...
