The derivation of coronary sinus flow during increased pulmonary and right ventricular pressures was resubmitted to experimental study. The primary reduction and subsequent augmentation in coronary flow following pulmonary artery constriction and the persistence of a greater flow after release preclude the concept of a variable contribution via thebesian channels from the right ventricular cavi...

Background: Scimitar syndrome (SS) or congenital pulmonary venolobar syndrome is a rare anomaly, most commonly including partial pulmonary venous drainage into the inferior vena cava, right lung hypoplasia, dextroposition of the heart, and anomalous systemic arterial supply from aorta or one of its branches to the right lung. Case report: A 10-day-old female infant was referred to our hospital...

QUESTION Does a modified postural drainage position (horizontal) produce less cardiovascular and respiratory stress than a head-down postural drainage position (30 degrees) in people with severe heart disease? DESIGN A quasi-experimental study. PARTICIPANTS Thirty-one patients (mean age 69 years, SD 13) with severe left ventricular systolic dysfunction (mean ejection fraction 23%, SD 7) who...

PURPOSE To evaluate whether post-hemorrhagic shock mesenteric lymph (PSML) is involved in cardiac dysfunction induced by hemorrhagic shock. METHODS The hemorrhagic shock model (40±2 mmHg, 3h) was established in rats of the shock and shock+drainage groups; and PSML drainage was performed from hypotension 1-3h in the shock+drainage rats. Then, the isolated hearts were obtained from the rats for...

BACKGROUND Despite the widespread use of external ventricular drainage, revision rates, and associated complications are reported between 10 and 40%. Current available image-guided techniques using stereotaxy, endoscopy, or ultrasound for catheter placements remain time-consuming techniques. Recently, a smartphone-assisted guide with high precision has been described. The development of an easy...

• For almost as long as the problem of venous return has been studied, two different factors have been claimed to be important in determining venous return to the heart." These are: (1) the force of the systemic arterial pressure pushing blood through the systemic circulation toward the heart, and (2) factors on the venous side of the heart that affect venous return, including rhythmic suction ...
