Initial Management of Right Ventricular Dysfunction

Evaluation and Diagnosis

The American College of Cardiology recommends early identification of right ventricular dysfunction through echocardiography, evaluating contractility, dilation, and pulmonary pressures in patients with suspected right ventricular dysfunction 1
The evaluation should include identification of specific signs such as right ventricular dilation, abnormal wall motion (especially in the subcostal short-axis view), and bowing of the interatrial septum towards the left atrium 1
In patients with inferior myocardial infarction, the clinical triad of hypotension, clear lung fields, and elevated jugular venous pressure should be sought, although its sensitivity is less than 25% 2

Maintaining adequate right ventricular preload is fundamental to optimizing its function, according to the American College of Cardiology 2
Avoiding volume overload, especially in cases of concomitant pulmonary hypertension, is crucial 3, 4
Using blood products instead of crystalloids or colloids for volume resuscitation when necessary is recommended 3, 4

The American College of Cardiology suggests administering a volume load with normal saline solution (500 ml bolus, followed by 500 ml/h) in right ventricular infarction, unless there are signs of left-sided volume overload 2
Avoiding the use of nitrates, diuretics, and other vasodilators that may reduce preload in cases of right ventricular infarction is recommended 2
Inhibitors of the angiotensin-converting enzyme are first-line therapy in patients with reduced left ventricular systolic function who also have right-sided heart failure 5

Continuous monitoring of heart rate, rhythm, blood pressure, and oxygen saturation for at least the first 24 hours is recommended 5
Consideration of transthoracic or transesophageal echocardiography to guide therapy is suggested 3, 4

In cases of severe right ventricular dysfunction refractory to medical management, consideration of extracorporeal membrane oxygenation (ECMO) is recommended 3, 4
Avoiding excessive fluid administration in patients with massively dilated right ventricles, as it may increase right ventricular distension and compromise left ventricular filling, is crucial 5

Delaying the diagnosis and treatment of right ventricular dysfunction, which can lead to irreversible damage 1, 9
Administering excessive fluids in patients with concomitant pulmonary hypertension 3, 4
Using systemic vasodilators without considering their effect on right ventricular preload, especially in right ventricular infarction 2
