Left ventricular external constraint: relationship between pericardial, pleural and esophageal pressures during positive end-expiratory pressure and volume loading in dogs.

Annals of biomedical engineering

Kingma I, Smiseth OA, Frais MA, Smith ER, Tyberg JV.
PMID: 3310760
Ann Biomed Eng. 1987;15(3):331-46. doi: 10.1007/BF02584288.

Left ventricular (LV) diastolic filling is limited by the constraining effects exerted by the pericardium (PE) and the lung/chest wall. The aim of the present study was to assess the validity of various estimates of external cardiac constraint, compared...

Ventricular diastole and the role of the pericardium.

Herz

Tyberg JV, Smith ER.
PMID: 2279730
Herz. 1990 Dec;15(6):354-61.

In order to understand the mechanics of left ventricular (LV) diastolic filling it has become important to understand the role of the pericardium. This is because it has been demonstrated that the LV pressure-volume relationship can be shifted by...

Experimental instrumentation and left ventricular pressure-strain relationship.

The American journal of physiology

Scott-Douglas NW, Traboulsi M, Smith ER, Tyberg JV.
PMID: 1750527
Am J Physiol. 1991 Dec;261(6):H1693-7. doi: 10.1152/ajpheart.1991.261.6.H1693.

Pericardial pressure measurement with a balloon transducer requires opening and reapproximating the pericardium. If this instrumentation significantly compromises pericardial volume, the heart may be constrained, exaggerating the magnitude of pericardial pressure and thus altering the left ventricular end-diastolic pressure-volume...
