Right Ventricular Echocardiography in caRdiac SurgEry

Right Ventricular Dysfunction

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)).

General Plus Spinal Anesthesia and General Anesthesia Alone on Right Ventricular Function

Right Ventricular Dysfunction

The investigator hypothesize that High Spinal Anesthesia (HSA) by its effect on attenuation of stress response, decrease in pulmonary vascular resistance, myocardial protection and positive myocardial oxygen balance will cause improvement in right ventricular function. So far there is no study that has evaluated the effect of HSA anesthesia on the right ventricular function, hence the investigator planned this study to compare the effect of HSA on the right ventricular function in patients with mitral valve disease with moderate to severe pulmonary hypertension planned for mitral valve replacement surgery.

A Post-Marketing Study for On Label Evaluation of the GE Vscan Ultrasound Imaging System

Left Ventricular DysfunctionRight Ventricular Dysfunction2 more

This study is to collect data and learn more about the Vscan Ultrasound Imaging System. It is an "observational" study with no additional procedures or intervention prescribed other than using the Vscan along with a routine medical physical exam.

Paceport Swan-Ganz Data Collection Study

Right Ventricular DysfunctionRight Heart Failure1 more

RV dysfunction has been associated with increased mortality in the ICU and cardiac surgical patients. Thus, early identification of RV dysfunction at less severe stages will allow for earlier intervention and potentially better patient outcomes. However, so far, no studies have reported prospectively the prevalence of abnormal RV pressure waveform during cardiac surgery and in the ICU. Our primary hypothesis is that the prevalence of abnormal RV pressure waveform occurs in more than 50% of cardiac surgical patients throughout their hospitalization. Those patients with abnormal RV pressure waveform will be more prone to post-operative complications related to RV dysfunction and failure in the OR and ICU.

PRediction of Early PostoperAtive Right vEntricular Failure in Mitral Valve Replacement/Repair Patients...

Right Heart FailureRight Ventricular Dysfunction2 more

The PREPARE-MVR (PRediction of Early PostoperAtive Right vEntricular failure in Mitral Valve Replacement/Repair patients) Study aims to evaluate those preoperative factors which can predict the early postoperative right ventricular failure or determine the functional shift seen in right ventricular function after mitral valve replacement/repair. The PREPARE-MVR study focuses mainly on echocardiographic (both conventional and advanced) parameters and includes right heart catheterization intraoperatively and in the early postoperative period as gold standard method.

Detection of Right Ventricular Dysfunction by 2D Strain During Acute Respiratory Distress Syndrom...

Acute Respiratory Distress SyndromeRight Ventricular Dysfunction2 more

Acute respiratory distress syndrome (ARDS) and mechanical ventilation can lead to right ventricular dysfunction and ultimately right ventricular failure by increasing pulmonary vascular resistances and pressure load. This can be prevented by modifying ventilator settings, using vasopressors or inotropes or even by prone positionning.But to do so, right ventricular dysfonction has to be detected. Echocardiography has emerged as a first line tool to diagnose right heart failure. Recently, strain analysis showed promising results to detect early right ventricle abnormalities in other settings such as pulmonary hypertension or scleroderma. We therefore decided to determine whether 2D strain could help detect early right ventricular dysfunction in ARDS.
