Precision perioperative RV and pulmonary artery pressure monitoring integrates 3D volumetric assessment, RV strain, splanchnic and renal venous congestion repercussions, and air embolic burden. See Article page 1430 in the April 2020 issue. Right ventricular (RV) failure has been long recognized by cardiac surgeons as a major cause of morbidity and mortality.1Dávila-Román V.G. Waggoner A.D.

The study of Singh and colleagues8Singh A. Huang X. Dai L. Wyler D. Alfirevic A.

Its strength lies in describing the dynamic of RV changes at key perioperative moments and in variable types of surgery. Almost 30 years ago, Popp and associates9Wranne B. Pinto F.J. Hammarstrom E. St Goar F.G. Puryear J. Popp R.L. Abnormal right heart filling after cardiac surgery: time course and mechanisms.Br Heart J. 1991; 66: 435-442Crossref PubMed Scopus (98) Google Scholar observed impairment in tricuspid annular excursion following cardiac surgery. One important question raised by this observation was whether longitudinal RV function reflects global systolic function. In fact, one of the challenges in assessing RV function resides it its complex geometry. By means of 3-dimensional echocardiography, Tamborini and coworkers10Tamborini G. Muratori M. Brusoni D. Celeste F. Maffessanti F. Caiani E.G. et al.Is right ventricular systolic function reduced after cardiac surgery? A two- and three-dimensional echocardiographic study.Eur J Echocardiogr. 2009; 10: 630-634Crossref PubMed Scopus (169) Google Scholar showed that despite the postoperative reduction of tricuspid annular excursion, 3-dimensional RV ejection fraction remained preserved at 3 postoperative months. The study of Singh and colleagues8Singh A. Huang X. Dai L. Wyler D. Alfirevic A.

Systolic parameters are, however, only one component of right heart performance.11Lang R.M. Badano L.P. Mor-Avi V. Afilalo J. Armstrong A.

Fletcher N. et al.Diagnostic workup, etiologies and management of acute right ventricle failure: a state-of-the-art paper.Intensive Care Med. 2018; 44: 774-790Crossref PubMed Scopus (88) Google Scholar When this RV-arterial coupling is less than 1, then the RV will enlarge to maintain cardiac output, but at the expense of venous congestion. This concept in recent years has led to an emphasis beyond systolic and diastolic RV parameters toward both forward (low cardiac output) and backward (venous congestion) consequences of RV dysfunction. This can lead to a vicious cycle of decreased overall tissue perfusion and congestion to the brain, liver, spleen, gut, and kidney21Sundaram V. Fang J.C.

In addition, both abnormal portal and renal venous pulsatilities were associated with prolonged duration of stay in the intensive care unit, excessive bleeding, reoperation, acute renal failure, and increased overall complication rate.23Beaubien-Souligny W.

In conclusion, we are currently entering an era of precision right heart monitoring. This monitoring integrates RV and pulmonary artery pressure monitoring, 3-dimensional volumetric and strain assessments, assessment of congestive end-organ repercussion, as well as perioperative monitoring for air embolic burden. Right ventricular function is reduced during cardiac surgery independent of procedural characteristics, reoperative status, or pericardiotomyThe Journal of Thoracic and Cardiovascular SurgeryVol. 159Issue 4PreviewLong-axis right ventricular (RV) function, which provides nearly 80% of RV ejection, acutely decreases during cardiac surgery. RV dysfunction increases risk for perioperative morbidity and mortality. Our objective was to characterize the change in perioperative RV long-axis and global function by determining the influence of procedure type, surgical approach, and reoperative status and examining its temporal relationship to pericardiotomy versus cardiopulmonary bypass (CPB) and cardioplegia.
