“…Under different PVR conditions, the LVEF and RVEF of the three surgeries in this paper were all about 50%. This result indicates a better ventricular function under the given PVR (Surkova et al, 2019). As PVR increases, the afterload of the right ventricle increases and EF decreases.…”

Objective: The one and a half ventricle repair (1.5VR) is a common clinical choice for patients with right heart dysfunction. Considering the influence of blood circulation failure and reoperation in urgent need, this essay aims to explore the hemodynamic effects of different pulmonary vascular resistance (PVR) values on reoperation after 1.5VR failure. Methods: The lumped parameter model (LPM) was used to simulate the reoperation, including the return biventricular repair (2VR), ligation of azygos vein (1.5VR) and return single ventricular repair (1.0VR). Firstly, the debugging parameters were used to simulate the hemodynamics of 2VR. Secondly, the value of PVR was changed from one to four times while the other parameters remained unchanged. Finally, 15 cardiac cycles were simulated and the 15th result was obtained. In this work, the left and right ventricular stroke work and their sum (Plv, Prv, Ptotal), the left and right ventricular ejection fraction (LVEF, RVEF), the mean Cardiac Output (mCO) and the mean pressure and flow-rate ratio of superior and inferior vena cava (mPsvc\mPivc and mQsvc\mQivc), respectively, were used to describe the hemodynamics of reoperation. Results: With the change of PVR from one to four times, the values of Plv, Prv, Ptotal, LVEF, and RVEF gradually decreased. The change rate of Plv, Ptotal and LVEF of 1.0VR were the largest in the three kinds of reoperation. The change rate of Prv of 1.5VR was larger than that of 2VR, but it was the opposite for their EF change rate. The mCO of 2VR, 1.5VR , and 1.0VR decreased by 18.53%, 37.58%, and 48.07%, respectively. The mPsvc\mPivc of 1.5VR increased from 3.76 to 6.77 and the mQsvc\mQivc decreased from 0.55 to 0.36, while the mPsvc\mPivc and mQsvc\mQivc of 2VR and 1.0VR remained 1 and 0.67, respectively. The peak value of the tricuspid flow-rate (Qti) waveform of 2VR and 1.5VR changed from "E peak" to "A peak."

“…The RV systolic dysfunction is an independent predictor of cardiovascular morbidity and mortality in various conditions [2,10,11]. In the absence of a single reliable measure in conventional echocardiography, a number of surrogate echocardiographic parameters of RV performance (such as tricuspid annular plane systolic excursion (TAPSE), peak S wave velocity of the lateral tricuspid annulus by tissue Doppler imaging (S'), RV fractional area change (FAC), and RV myocardial performance index) have been introduced for clinical use.…”

“…Over the last few decades the right ventricle (RV) gained recognition as a key player in cardiac (patho-) physiology and independent predictor of adverse events and mortality in patients with heart failure, pulmonary hypertension, coronary artery disease, left ventricular (LV) dysfunction, congenital heart disease, respiratory distress syndrome, and even in general population of patients undergoing clinically indicated transthoracic echocardiography [1][2][3][4]. Precise evaluation of the RV performance is considered crucially important but challenging task due to RV complex geometry and myocardial fiber architecture, prominent trabeculation and its sensitivity to loading conditions.…”

Right ventricular (RV) performance is an important predictor of adverse events and mortality in patients with cardiovascular diseases. Echocardiography is the first-choice imaging modality for the assessment of RV systolic function, however conventional two-dimensional echocardiographic parameters have important limitations and under specific conditions poorly correlate with the gold-standard imaging modality, cardiac magnetic resonance. Recent advances in novel echocardiography techniques, including three-dimensional echocardiography and two-dimensional speckle-tracking echocardiography opened new era in RV imaging enabling more accurate and reproducible assessment of RV performance thus providing deeper insight into the pathophysiology of this intriguing cardiac chamber. In this comprehensive review authors summarize the state-of-the-art echocardiographic approach to the assessment of the RV systolic function with specific emphasis on modern techniques, their advantages, limitations and pitfalls in the various clinical settings.

“…[22][23][24][25][26][27][28][29] Over the past 20-to-25 years, many reports associated outcome with RV systolic function, with some recognizing RV function as the stronger or sole predictor of outcome. 22,23,[29][30][31] When does the RV become a critically important chamber and how is this transition identified? Until recently, investigations have focused on right ventricular systolic function and associated outcomes.…”

the Heart and Blood in Living Beings," recognized that pulsatile flow through the arterial vessels was coordinated with the contraction of the heart muscle. Harvey described a "double circulation" where ".. . the blood, forced by the action of the left ventricle into the arteries, was distributed to the body at large, and its several parts, in the same manner as it is sent through the lungs, impelled by the right ventricle into the pulmonary artery." 1,2
