Isovolumic relaxation abnormalities have been noted in the ischemic left ventricle, but altered end-diastolic distensibility, as well as the role of right ventricular distention, is debated. Accordingly, left ventricular end-diastolic pressure and myocardial segment length were studied in the open-chest dogs with critical (90% diameter reduction) stenoses on both left anterior descending and ci...

background pulmonary artery hypertension is the presentation of various types of cardiovascular and systematic diseases. there are different kinds of noninvasive methods to determine right ventricular function, pulmonary artery pressure, and effect of pulmonary hypertension on right ventricular function. these methods include the tissue doppler imaging (tdi) of the tricuspid annulus and the lon...

Dept of Clinical Physiology, Lund University, Lund, Sweden Full list of author information is available at the end of the article Figure 1 Comparison of kinetic energy (KE) (top) and KE indexed for ventricular stroke volume (SV) (bottom) between ToF patients and controls in both left ventricle (LV) and right ventricle (RV). Bar and whiskers show mean ± SD. Sjöberg et al. Journal of Cardiovascul...

The long-term follow-up of six patients operated on for aorto-left ventricular communication has been reviewed in detail. All had residual aortic regurgitation after the initial repair of the defect. It was severe in four and required repeated reoperation in three with ultimate aortic valve replacement. The failure of early repair to solve the haemodynamic problem has provoked a reconsideration...

Here, we report a rare case of a 23-year-old term parturient with Eisenmenger syndrome due to Taussig-Bing anomaly presenting with gestational hypertension, oligohydramnios, and intrauterine growth retardation posted for elective cesarean section. Preoperatively, echocardiography of the patient was suggestive of double-outlet right ventricle (DORV) with large sub-pulmonic ventricular septal def...

The importance of right ventricular (RV) function in cardiovascular disease and cardiac surgery has been recognized for several years. RV dysfunction has been shown to be a significant prognostic factor in cardiac surgery and heart transplantation. In the first article of this review, key features of RV anatomy, physiology, and assessment were presented. In this second part, we review the patho...
