Postoperative right ventricular (RV) dysfunction increases mortality and risk of cardiac failure after cardiac surgery substantially. A comprehensive understanding of this condition is paramount in order to achieve success in treatment and early diagnosis. This study has two main aims. Perioperative aim: To investigate correlations between changes in echocardiographic measurements and hemodynamic changes at baseline and following coronary artery bypass graft (CABG) surgery. Postoperative aim: To evaluate changes in haemodynamics and echocardiographic parameters during separate physiological interventions (increase in preload/afterload, oxygen fraction, pacing modes (AAI/DDD/VVI)).
The SQ_Heart has been designed as an observational study that evaluates the difference in sleep quality between 11 patients with VAD (Ventricular Assisted Device) and 98 Cardiotransplant patients.
Prospective, multi-center, single arm, post approval study to be conducted in the United States.
The primary reason the investigators are doing this study are to understand how the right side of the heart functions in heart failure patients with left ventricular assist devices (LVADs, or "mechanical hearts"). Second, the investigators are interested in understanding how different pacemaker settings influence function of the heart at rest and activity.
To establish the correlation between echocardiographic parameters of the RV, measured with TEE and the right ventricular ejection fraction (thermodilution). To identify a time in the perioperative process when RV dysfunction occurs.
This study evaluates whether a preoperative assessment of myocardial contractile reserve by tissue Doppler Imaging and myocardial fibrosis by cardiac magnetic resonance imaging (MRI) can enhance the patient selection and risk stratification to transcatheter aortic valve implantation.
The purpose of this study is to evaluate whether preoperative optimization with levosimendan in heart failure patients undergoing hip fracture surgery improves haemodynamic and tissue perfusion parameters.
Our investigation studies the role of acute insulin administration on the diabetic heart, its corresponding effective blood-insulin level and the time-course applicability of insulin in a routine clinical setting. A case series of six male (48.1 ± 4.9 y/o) patients with controlled diabetes (HbA1c of 6.6 ± 0.3%, disease duration of 14.4 ± 6.7 yr). Each subject was evaluated for glucose homeostatic, hemodynamic and echocardiographic systolic and diastolic parameters at baseline and following two successive insulin-load steps of a euglycemic hyperinsulinemic clamp study, each 2 h in duration. Results are presented as a mean ± SEM and analysed using the student's t-test.
The purpose of this study was to investigate the influence of micro- and macrovascular changes on the cardiac function in relation to left ventricular function and coronary arteries during one year in patients with type 2 diabetes.
