Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The mechanisms behind RVD post-surgery involve changes in preload, after load, and RV contraction. Factors linked to higher incidence of postoperative RVD include decreased tricuspid annular plane excursion (TAPSE), elevated preoperative pulmonary artery pressure, lung diseases, duration of extracorporeal circulation, and left valve surgery.
While predictive scores for RVD exist for left ventricular assist device (LVAD) patients, no such models are available for other cardiac surgeries. Identifying specific predictors could lead to models that identify high-risk patients, allowing for tailored monitoring and treatment strategies.
The primary aim of this study is to create a preoperative risk score for predicting the development of right ventricular dysfunction following adult cardiac surgery through a retrospective analysis on patients who underwent heart surgery.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
\- Echocardiographic parameters suggestive of RVD (at least 2 out of 3): TAPSE \< 16 mmHg; right ventricular fractional area change (RVFAC) \< 35%; right ventricular end systolic dilation \> 3,5 cm (measured from the septum to the free wall).
AND
\- Need for inotropic and/or pulmonary vasodilator drug support and/or mechanical support.
Data will be collected retrospectively on: demographic characteristics; basic patient characteristics (weight, height, Body Mass Index -BMI, etc.); preoperative pharmacological therapy; preoperative comorbidities; abnormalities in blood tests; chest X-rays and ECGs; abnormalities in coronary angiography and carotid ultrasound; preoperative echocardiographic examination: TAPSE, Left Ventricular Ejection Fraction- LVEF, valvular pathologies, Pulmonary Artery Systolic Pressure- PAPs, pericardial effusion; type of surgical intervention; occlusion of the posterior interventricular coronary artery (acute or chronic); duration of the surgical procedure; duration of extracorporeal circulation; non-revascularized right coronary artery disease; blood product transfusions; postoperative pharmacological therapy (with particular regard to the use of inotropes/pulmonary vasodilators/vasopressors); postoperative echocardiographic examination: TAPSE; RVFAC; right ventricular dilation at end-systole; postoperative complications; Intensive Care Unit (ICU) length of stay and hospital length of stay.
