The cyclo-oxygenase-dependent regulation of rabbit vein contraction: evidence for a prostaglandin E2-mediated relaxation. (1/230)

1. Arachidonic acid (0.01-1 microM) induced relaxation of precontracted rings of rabbit saphenous vein, which was counteracted by contraction at concentrations higher than 1 microM. Concentrations higher than 1 microM were required to induce dose-dependent contraction of vena cava and thoracic aorta from the same animals. 2. Pretreatment with a TP receptor antagonist (GR32191B or SQ29548, 3 microM) potentiated the relaxant effect in the saphenous vein, revealed a vasorelaxant component in the vena cava response and did not affect the response of the aorta. 3. Removal of the endothelium from the venous rings, caused a 10 fold rightward shift in the concentration-relaxation curves to arachidonic acid. Whether or not the endothelium was present, the arachidonic acid-induced relaxations were prevented by indomethacin (10 microM) pretreatment. 4. In the saphenous vein, PGE2 was respectively a 50 and 100 fold more potent relaxant prostaglandin than PGI2 and PGD2. Pretreatment with the EP4 receptor antagonist, AH23848B, shifted the concentration-relaxation curves of this tissue to arachidonic acid in a dose-dependent manner. 5. In the presence of 1 microM arachidonic acid, venous rings produced 8-10 fold more PGE2 than did aorta whereas 6keto-PGF1alpha and TXB2 productions remained comparable. 6. Intact rings of saphenous vein relaxed in response to A23187. Pretreatment with L-NAME (100 microM) or indomethacin (10 microM) reduced this response by 50% whereas concomitant pretreatment totally suppressed it. After endothelium removal, the remaining relaxing response to A23187 was prevented by indomethacin but not affected by L-NAME. 7. We conclude that stimulation of the cyclo-oxygenase pathway by arachidonic acid induced endothelium-dependent, PGE2/EP4 mediated relaxation of the rabbit saphenous vein. This process might participate in the A23187-induced relaxation of the saphenous vein and account for a relaxing component in the response of the vena cava to arachidonic acid. It was not observed in thoracic aorta because of the lack of a vasodilatory receptor and/or the poorer ability of this tissue than veins to produce PGE2.  (+info)

Pulmonary and caval flow dynamics after total cavopulmonary connection. (2/230)

OBJECTIVE: To assess flow dynamics after total cavopulmonary connection (TCPC). DESIGN: Cross-sectional study. SETTING: Aarhus University Hospital. PATIENTS: Seven patients (mean age 9 (4-18) years) who had previously undergone a lateral tunnel TCPC mean 2 (0. 3-5) years earlier. INTERVENTIONS: Pressure recordings (cardiac catheterisation), flow volume, and temporal changes of flow in the lateral tunnel, superior vena cava, and right and left pulmonary arteries (magnetic resonance velocity mapping). RESULTS: Superior vena cava flow was similar to lateral tunnel flow (1.7 (0.6-1.9) v 1. 3 (0.9-2.4) l/min*m2) (NS), and right pulmonary artery flow was higher than left pulmonary artery flow (1.7 (0.6-4.3) v 1.1 (0.8-2. 5) l/min*m2, p < 0.05). The flow pulsatility index was highest in the lateral tunnel (2.0 (1.1-8.5)), lowest in the superior vena cava (0.8 (0.5-2.4)), and intermediate in the left and right pulmonary arteries (1.6 (0.9-2.0) and 1.2 (0.4-1.9), respectively). Flow and pressure waveforms were biphasic with maxima in atrial systole and late ventricular systole. CONCLUSIONS: Following a standard lateral tunnel TCPC, flow returning via the superior vena cava is not lower than flow returning via the inferior vena cava as otherwise seen in healthy subjects; flow distribution to the pulmonary arteries is optimal; and some pulsatility is preserved primarily in the lateral tunnel and the corresponding pulmonary artery. This study provides in vivo data for future in vitro and computer model studies.  (+info)

Rate-dependent conduction block of the crista terminalis in patients with typical atrial flutter: influence on evaluation of cavotricuspid isthmus conduction block. (3/230)

BACKGROUND: The crista terminalis (CT) has been identified as the posterior boundary of typical atrial flutter (AFL) in the lateral wall (LW) of the right atrium (RA). To study conduction properties across the CT, rapid pacing was performed at both sides of the CT after bidirectional conduction block was achieved in the cavotricuspid isthmus by radiofrequency catheter ablation. METHODS AND RESULTS: In 22 patients (aged 61+/-7 years) with AFL (cycle length, 234+/-23 ms), CT was identified during AFL by double electrograms recorded between the LW and posterior wall (PW). After the ablation procedure, decremental pacing trains were delivered from 600 ms to 2-to-1 local capture at the LW and PW or coronary sinus ostium (CSO). At least 5 bipolar electrograms were recorded along the CT from the high to the low atrium next to the inferior vena cava. No double electrograms were recorded during sinus rhythm in that area. Complete transversal conduction block all along the CT (detected by the appearance of double electrograms at all recording sites and craniocaudal activation sequence on the side opposite to the pacing site) was observed in all patients during pacing from the PW or CSO (cycle length, 334+/-136 ms), but it was fixed in only 4 patients. During pacing from the LW, complete block appeared at a shorter pacing cycle length (281+/-125 ms; P<0.01) and was fixed in 2 patients. In 3 patients, complete block was not achieved. CONCLUSIONS: These data suggest the presence of rate-dependent transversal conduction block at the crista terminalis in patients with typical AFL. Block is usually observed at longer pacing cycle lengths with PW pacing than with LW pacing. This difference may be a critical determinant of the counterclockwise rotation of typical AFL.  (+info)

Hepatic vascular exclusion with preservation of the caval flow for liver resections. (4/230)

OBJECTIVE: To report the technique and results of an alternative method of vascular clamping during liver resections. BACKGROUND: Most liver resections require vascular clamping to avoid excessive blood loss. Portal triad clamping is often sufficient, but it does not suppress backflow bleeding, which can be prevented only by hepatic vascular exclusion. The latter method adds clamping of the inferior vena cava, which results in hypotension, requiring invasive anesthetic management. There is growing evidence that intermittent clamping is better tolerated than continuous clamping, especially in the presence of underlying liver disease. METHODS: Hepatic vascular exclusion with preservation of the caval flow (HVEPC) involved conventional inflow clamping associated with outflow control by clamping the major hepatic veins, thus avoiding caval occlusion. HVEPC was used in 40 patients undergoing major or complex liver resection, including 16 with underlying liver disease. HVEPC was total (clamping of the porta hepatis and all major hepatic veins) in 20 cases and partial (clamping of the porta hepatis and the hepatic veins of the resected territory) in 20. Clamping was continuous in 22 cases and intermittent in 18. Resections included 12 hemihepatectomies, 12 extended hepatectomies, 3 central hepatectomies, and 13 uni- or bisegmentectomies. RESULTS: Hemodynamic tolerance of clamping was excellent in all cases, without the need for therapeutic adjustment. Median red cell transfusion requirements were 0 units, and 28 patients (70%) did not receive any transfusions during the hospital stay. There were no deaths, and the morbidity rate was 17.5%. Median hospital stay was 10 days. CONCLUSION: HVEPC is a safe and effective procedure applicable to liver tumors without invasion to the inferior vena cava. It offers the advantages of conventional hepatic vascular exclusion without its hemodynamic drawbacks, and it can be applied intermittently or partially.  (+info)

Cardiac consequences of prolonged exposure to an isolated increase in aortic stiffness. (5/230)

In elderly patients, aortic stiffness is a major determinant of increased end-systolic stress leading to left ventricular (LV) hypertrophy with impaired cardiac performance. However, in a rat model of aortic elastocalcinosis (induced by vitamin D(3)-nicotine [VDN] treatment), brief exposure (1 month) to increased aortic stiffness modified neither cardiac function nor cardiac structure. Here we report the impact of longer exposure (3 months) to aortic stiffness. Three months after induction of aortic stiffness, aortic characteristic impedance was measured in awake rats, 8 control and 10 VDN. Stroke volume was measured (electromagnetic probe) at baseline and after acute volume overload. LV weight/body weight ratio, collagen, and myosin heavy chain (MHC) contents were determined. Although aortic characteristic impedance increased (controls, 32+/-2; VDN rats, 50+/-8 10(3) dyne. s/cm(5); P=0.0248), stroke volume was maintained in VDN rats at baseline (controls, 223+/-18; VDN, 211+/-13 microL) and after volume overload (controls, 378+/-14; VDN, 338+/-15 microL). However, LV weight/body weight ratio (controls, 1.54+/-0.07; VDN, 1.73+/-0.05 g/kg; P=0.0397) and LV collagen content (controls, 31+/-4; VDN, 52+/-4 microgram/g dry wt; P=0.0192) increased. A shift from alpha-MHC (controls, 82+/-2%; VDN, 69+/-3%; P=0.0056) to beta-MHC (controls, 18+/-2%; VDN, 31+/-3%; P=0. 0056) was also observed. Three months' exposure to increased aortic stiffness in VDN rats induced LV hypertrophy with moderate interstitial fibrosis and a shift in the MHC-isoform pattern. Such structural adaptation maintains LV performance.  (+info)

Tissue factor activity is increased in human endothelial cells cultured under elevated static pressure. (6/230)

We tested the hypothesis that elevated blood pressure, a known stimulus for vascular remodeling and an independent risk factor for the development of atherosclerotic disease, can modulate basal and cytokine-induced tissue factor (TF; CD 142) expression in cultured human endothelial cells (EC). Using a chromogenic enzymatic assay, we measured basal and tumor necrosis factor-alpha (TNF-alpha; 10 ng/ml, 5 h)-induced TF activities in human aortic EC (HAEC) and vena cava EC (HVCEC) cultured at atmospheric pressure and at 170 mmHg imposed pressure for up to 48 h. Basal TF activities were 22 +/- 10 U/mg protein for HAEC and 14 +/- 9 U/mg protein for HVCEC and were upregulated in both cell types >10-fold by TNF-alpha. Exposure to pressure for 5 h induced additional elevation of basal TF activity by 47 +/- 16% (P < 0.05, n = 6) for HAEC and 17 +/- 5% (P < 0.05, n = 3) for HVCEC. Pressurization also enhanced TF activity in TNF-alpha-treated cells from 240 +/- 28 to 319 +/- 32 U/mg protein in HAEC (P < 0.05, n = 4) and from 148 +/- 25 to 179 +/- 0.8 U/mg protein (P < 0.05, n = 3) in HVCEC. Cytokine stimulation caused an approximately 100-fold increase in steady-state TF mRNA levels in HAEC, whereas pressurization did not alter either TF mRNA or cell surface antigen expression, as determined by quantitative RT-PCR methodology and ELISA. Elevated pressure, however, modulated the EC plasma membrane organization and/or permeability as inferred from the increased cellular uptake of the fluorescent amphipathic dye merocyanine 540 (33 +/- 7%, P < 0.05). Our data suggest that elevated static pressure modulates the hemostatic potential of vascular cells by modifying the molecular organization of the plasma membrane.  (+info)

Inhibition of neointima hyperplasia of mouse vein grafts by locally applied suramin. (7/230)

BACKGROUND: Saphenous vein grafts are widely used for aortocoronary bypass surgery as treatment for severe atherosclerosis and often are complicated by subsequent occlusion of the graft vessel. METHODS AND RESULTS: We described a mouse model of venous bypass graft arteriosclerosis that can be effectively retarded by locally applied suramin, a growth factor receptor antagonist. Mouse isogeneic vessels of the vena cava veins pretreated with suramin were grafted end to end into the carotid arteries and enveloped with a mixture of suramin (1 mmol/L) and pluronic-127 gel. In the untreated group, vessel wall thickening was observed as early as 1 week after surgery and progressed to 4-fold and 10-fold the original thickness in grafted veins at 4 and 8 weeks, respectively. Pluronic-127 gel alone did not influence neointima formation. Suramin treatment reduced the neointima hyperplasia 50% to 70% compared with untreated controls. Immunohistochemical studies demonstrated that a significant proliferation of vascular smooth muscle cells (SMCs) constituted neointimal lesions between 4 and 8 weeks. The majority of SMCs expressed platelet-derived growth factor (PDGF) receptors-alpha and -beta, which were significantly reduced by suramin treatment. In vitro studies indicated that suramin completely blocked PDGF receptor activation or phosphorylation stimulated by PDGF-AB, inhibited activation of mitogen-activated protein kinase (ERK) kinases (MEK1/2) and ERK1/2, and abrogated transcription factor AP-1 DNA-binding activity. CONCLUSIONS: Suramin inhibited SMC migration and proliferation in vivo and in vitro by blocking PDGF-initiated PDGF receptor and MAPK-AP-1 signaling. These findings indicate that locally applied suramin is effective in a mouse model of venous bypass graft arteriosclerosis.  (+info)

Aromatase and sex steroid receptors in human vena cava. (8/230)

Among sex steroids, especially estrogen metabolism has been considered to play a role in the function and pathology of human veins. We investigated the expression and activity of the estrogen-producing enzyme aromatase and estrogen receptor (ER) in human vena cava to assess possible in situ biosynthesis of estrogens and their modes of action. We first examined aromatase expression by immunohistochemistry in human inferior vena cava obtained from 29 autopsy cases (11 males, 18 females, 63.6 +/- 3.0 years old). We then semiquantitated the level of aromatase mRNA by reverse transcriptase-polymerase chain reaction in 24 cases and aromatase activity by 3H-water assay in 15 cases to examine whether or not and in which cell types aromatase was expressed. We also studied alternative use of multiple exon 1s of its gene and immunolocalization of 17beta-hydroxysteroid dehydrogenase type I (17beta-HSD I), which converts estrone produced by aromatase to estradiol, a biologically active estrogen and ER. Aromatase and 17beta-HSD I immunoreactivity were both detected in smooth muscle cells (SMC) of the media in all the cases and in endothelial cells (EC) in 20 and 22 cases, respectively. ER immunoreactivity was detected in SMC of vena cava in 21 cases. The amount of aromatase mRNA was significantly greater in the cases utilizing 1c (I.3) or 1d (P.II) of exon 1 (9 cases, 191.1 +/- 26.3 attomol/ng total RNA) than those utilizing 1b (I.4) as the promoter (14 cases, 50.6 +/- 13.0 attomol/ng total RNA) (p < 0.01). Significant correlation (p < 0.05) was observed between the amount of aromatase mRNA and aromatase activity in 15 cases examined. No significant correlation was detected between the amount of aromatase mRNA or aromatase labeling index and the ER status. These results suggest that estrone and estradiol are produced in the human vena cava and that their production is mediated by aromatase and 17beta-HSD I, respectively but not all of these locally synthesized estrogens may not work directly in situ.  (+info)

View Notes - mpworksheet62 from BIPN 100 at UCSD. BIPN10 - Fortes Cardiac Cycle 1. Heart is relaxed, so blood flows from the veins (vena cavae) into the right atrium, and from the pulmonary veins
As venous return increases, the pressure in the superior and inferior vena cavae increase. This results in an increase in the pressure of the right atrium, which stimulates the atrial stretch receptors. These receptors in turn signal the medullary control centers to increase sympathetic stimulation of the heart, leading to increased heart rate, a.k.a. tachycardia. Increasing the heart rate serves to decrease the pressure in the superior and inferior vena cavae by drawing more blood out of the right atrium. This results in a decrease in atrial pressure, which serves to bring in more blood from the vena cavae, resulting in a decrease in the venous pressure of the great veins. This continues until right atrial blood pressure returns to normal levels, upon which the heart rate decreases to its original level. ...

As I will show, the next key stage in cardiac development is rightward expansion of the atrioventricular canal, such that the cavity of the right atrium is able directly to drain to the developing right ventricle. As can be seen in Figures 8 and 9, however, the parietal wall of the right atrium at the rightward margin of the atrioventricular canal is already in continuity with the roof of the right ventricle, even though the circumference of the atrioventricular canal itself is supported above the cavity of the developing left ventricle (right hand panel, Figure 8). If the atrioventricular canal failed to expand, yet the remainder of the heart continued its development, the end result would be that the atrial chambers would retain their connection with the left ventricle. This is the derangement that produces the abnormal situation known as double inlet left ventricle (Figure 10). In this arrangement, the left ventricle remains as the dominant chamber in the ventricular mass, with the right ...

The heart is a muscular organ the size of a fist, whose function is to continuously pump blood around the body. It is located in between the lungs, towards the left side of the chest. In humans, it is divided into four chambers. The heart pumps blood with a rhythm known as the heartbeat. A healthy human heart beats about 72 times per minute. The heart receives deoxygenated blood from the systemic circulation, which enters the right chamber through the superior and inferior venae cavae and is passed to the right ventricle. It then goes to the lung where it is oxygenated. The oxygenated blood returns to the left atrium, passes through the left ventricle and is returned to the systemic circulation through the aorta. This process is called the blood circulation.. The networks of blood vessels that circulate blood within the heart are called coronary arteries. The chambers of the heart pump blood through systolic and diastolic action. During systole, cardiac muscles contract to push blood out of the ...
At the beginning of the cardiac cycle, all four chambers of the heart, two atria and two ventricles are synchronously approaching relaxation and dilation, or diastole. The atria are filling with separate blood volumes returning to the right atrium (from the vena cavae) and to the left atrium (from the lungs). After chamber and back pressures equalize, the mitral and tricuspid valves open, and the return blood flows are passed through the atria into the ventricles. When the ventricles have completed most of their filling, the atria begin to contract (atrial systole), forcing blood under pressure into the ventricles. Now the ventricles start to contract, and as pressures within the ventricles rise, the mitral and tricuspid valves are closed. As pressures within the ventricles continue to rise, they exceed the back pressures in the aorta trunk and the pulmonary arteries trunk, and the aortic and pulmonary valves open-and now blood is ejected from the heart. Ejection causes pressure within the ...
These impulses ultimately stimulate heart muscle to contract and thereby to eject blood from the ventricles into the arteries and the cardiac circulatory system ; and they provide a system of intricately-timed and persistent signaling that controls the rhythmic beating of the heart muscle cells, especially the complex impulse-generation and muscle contractions in the atrial chambers.. Late in the filling period the atria begin to contract atrial systole forcing a final crop of blood into the ventricles under pressure-see cycle diagram. If one or both lungs are retracted by disease, heart sounds over an area of the heart not covered by the lung will seem intensified. Boston: Butterworths ; Now follows the isovolumic relaxationduring which pressure within the ventricles begin to fall significantly, and thereafter the atria begin refilling as blood returns to flow into the right atrium from the vena cavae and into the left atrium from the pulmonary veins.. Then ask the patient to turn to the left ...
A device and method for providing body cooling for treating fever. The cooling device applies cooling to blood flowing in a vein or artery, e.g., the vena cavae, that is then distributed throughout the body.
Results: Absolute and relative measurements of the trachea, heart, thoracic caudal vena cava and aorta, right and left principal bronchi, right and left caudal lobar bronchi and the accompanying branches of the right and left pulmonary artery and vein, right and left lung volume and lung density were taken. The three lobes of the thymus (right ventral, right dorsal and left thoracic lobes) were identified in all rabbits. Both the right dorsal and left thoracic lobes of the thymus extended between the heart and thoracic wall in all individuals with the left lobe reaching more caudally in seven animals. Consequently, the craniocaudal extension of the left lung was smaller than the right lung in these rabbits. Volume of the left lung was significantly smaller than the right (P = 0.005). The cranial mediastinal, right and left tracheobronchial and the aortic thoracic lymph nodes were very small and identified in four, four, seven and ten rabbits, respectively. The heart took up a median of 4.0 ...

Central venous pressure (CVP) is the blood pressure in the venae cavae, near the right atrium of the heart. CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood back into the arterial system. CVP is often a good approximation of right atrial pressure (RAP),[1] although the two terms are not identical, as a pressure differential can sometimes exist between the venae cavae and the right atrium. CVP and RAP can differ when arterial tone is altered. This can be graphically depicted as changes in the slope of the venous return plotted against right atrial pressure (where central venous pressure increases, but right atrial pressure stays the same; VR = CVP − RAP).. CVP has been, and often still is, used as a surrogate for preload, and changes in CVP in response to infusions of intravenous fluid have been used to predict volume-responsiveness (i.e. whether more fluid will improve cardiac output). However, there is increasing evidence that CVP, whether ...
During the fourth week of gestation, a pair of anterior cardinal veins form that drain the cephalic part of the embryo and a pair of posterior cardinal veins form that drain the rest. Anterior and posterior cardinal veins join to form a short common cardinal vein (duct of Cuvier), which opens into the respective horns of sinus venosus. The proximal portions of the right anterior cardinal veins and right common cardinal vein form the RSVC. The left anterior cardinal veins normally obliterate to form the ligament of Marshall, whereas the left horn of the sinus venosus and adjacent portion of the left common cardinal vein form the CS. Persistence of the left anterior cardinal vein forms the left SVC, which always continues with the CS as the left common cardinal vein that is part of both the CS and left SVC. Flow of PLSVC blood into the CS results in its enlargement, and a dilated CS is often the first clue for the diagnosis of PLSVC during echocardiography. In 82% to 90% of cases, PLSVC is ...

Description: Bilateral Left-Sidednessis a complex birth defect of congenital cardiac disease associated with multiple spleens (as contrasted to accessory spleen), there is a definite tendency for the symmetrical development of organs but with a tendency for bilateral left-sidedness or levo-isomerism. The abnormalities assumed one of three forms as follows: (1) absence of a normal right-sided structure, (2) bilateral organs, each with the structure of a left-sided organ, or (3) excessive tissue of a left-sided organ. Thus, in polysplenia there is a tendency for (1) absence of the hepatic segment of the inferior vena cava and absence of the gallbladder, (2) two lobes in each lung with hyparterial bronchi, and (3) multiple spleens. Other noncardiac abnormalities were partial or complete abdominal heterotaxia and partial malrotation of the bowel. The cardiac malformations included dextrocardia, bilateral superior venae cavae, anomalous pulmonary venous connection with malposition of the atrial ...
The referral vets report shows that the symptoms were caused by jejunal arteriovenous fistula, a malformation of the vessels of the small bowel. This is a rare anomaly that affects arteries and veins, where an artery merges with a vein before reaching the target organ. These malformations can affect many vessels. The result of high-pressure blood meeting low-pressure vessels (veins) caused damage to the veins and surrounding tissues. This is an extremely rare event in dogs, but Daisy was found to have an issue with her portal vein, the vein that delivers blood rich in nutrient from the intestine to the liver. The blood after being filtered by the liver would then reach a larger vein called caudal vena cava that would then deliver the blood to the right side of the heart. This portal vein was much narrower in diameter than that of a normal dog, and this condition is called hypoplastic portal vein. There is no cure for this condition. The result of having that smaller portal vein is a smaller ...
The purpose of the present study was to evaluate, through videothermometry, the temperature variation in the hearts of rabbits, that underwent induced myocardial ischemia and reperfusion. A total of 20 female rabbits were divided into two groups: a treated group and a sham group, the treatment group underwent 5 min of cardiac arrest and reperfusion, using the inflow occlusion technique. Throughout the experiment, the animals were monitored by videothermometry, observing the thermal variations of the myocardial tissue. During the experiment, at different times, blood gas tests and tests to evaluate the lactate concentrations were performed. At the end of the experiment, each heart was submitted to histopathological evaluation. In the treated group, there was a reduction in temperature of the myocardial tissue during the circulatory arrest compared to the sham group. Additionally, a colder area next to the caudal vena cava ostium and the right atrium was observed. Notably, despite the 5 min of cardiac
Signs of ascites were observed in only nine of 1863 cattle examined over a period of five years. The ascites was most commonly associated with either primary or secondary cardiac disease; cattle with ascites have a poor prognosis because the condition is usually assocaited with terminal disease. Two animals had cor pulmonale with chronic pneumonia, three had cardiomyopathy, one had bacterial endocarditis, two had thrombosis of the caudal vena cava and one had diffuse abdominal epithelioid mesothelioma.. ...
Background: Active using tobacco (CS) is a contraindication for Orthotopic Heart Transplantation (OHT) with a recommendation that HT candidates be free from CS for at minimum 6 months prior to HT. Caucasian (75.7 vs 62.3, p = 0.0001), male (81.7 vs 68.2, p = 0.0001), and diabetic (27.4 vs 24.4, p = 0.0001). CS was associated with significantly worse survival (HR: 1.23, p? ?0.0001). A history of CS was also associated with increased risk of acute rejection (OR: 1.20, p? ?0.0001), hospitalization for contamination (OR:1.24, p? ?0.0001), graft failure (OR:1.23, p? ?0.0001) and post-transplant malignancy (OR:1.43, p? ?0.0001). Conclusion: A history of CS is usually associated with increased risk of adverse events post OHT. test for categorical and continuous variables, respectively. Unadjusted associations between CS history and patient survival were decided using the Kaplan-Meier estimations and confounding was resolved using multivariable Cox proportional risks models.

A 6.5-year-old, female spayed German short-haired pointer dog was presented with a two-week history of ascites. The dog was depressed with a severely distended abdomen. Peritoneal fluid analysis revealed a modified transudate. A metallic linear foreign body was identified cranial to the pyloric antrum by advanced imaging. A fibrous tract of tissue extending from the pyloric antrum to the hilar region of the right medial liver lobe was dissected surgically. The foreign body was removed by dissection of the fibrous tract, which relieved visible compression of the caudal vena cava and all hepatic veins. By three days postoperatively, ascites had not resolved and a caudal cavagram confirmed narrowing of the thoracic caudal vena cava at the diaphragm. Eight days postoperatively, a caudal vena caval stent was placed, relieving the pressure gradient across the narrowing and resulting in complete resolution of clinical signs. ...
Objective: The aim of this study was to compare the requirement for temporary and permanent pacemaker insertion and the incidence of the problems regarding the rhythm following heart transplantation with the bicaval or biatrial technique in the early postoperative period.Methods: Sixty-one patients underwent orthotopic heart transplantation between the dates of September 1989 and December 2008 in our clinics were included to the study. The study was designed as retrospective analysis, and all data were collected from hospital records. The transplantation was performed by using standard biatrial method in 28 of the patients, by using bicaval anastomosis method in 33 of the patients. Statistical analyses were performed using Chi-square, Fischers exact and Mann-Whitney U tests. Predictors of temporary and permanent pacemaker insertion were analyzed using logistic regression analysis.Results: In the biatrial group, the temporary pacemaker requirement (p|0.05), left bundle branch block (LBBB) (p|0.01) and
Other abnormalities that can be noted secondary to anaphylaxis are an increase in serum alanine transaminase (ALT), hemoabdomen, vomiting, diarrhea as well as cutaneous signs. Although cutaneous signs are absent in nearly 95% of cases. The elevation in ALT typically lags several hours, therefore it cannot be relied upon in the immediate diagnosis of anaphylaxis. The mean value for ALT is 400 IU/L in anaphylactic canines. The hepatic venous congestion along with factors that contribute to acquired coagulopathy leads to a hemoabdomen. Unfortunately, gallbladder wall edema is not pathognomonic for canine anaphylaxis. In an acutely collapsed or hypotensive canine with gallbladder wall edema, you must rule out other differentials such as pericardial effusion, right-sided heart failure or dilated cardiomyopathy. The caudal vena cava can help determine the cause of the gallbladder wall edema because it is an indirect marker of volume status and central venous pressure. In anaphylaxis the caudal vena ...

In hooking a person up to the heart-lung machine, its necessary to control blood returning to the heart via the venae cavae. That requires (did then, anyway) slinging the veins with ties; to do so necessitates dissecting within the pericardium, behind those delicate structures, completely encircling them. Joe had a favorite instrument for the job, a very large clamp with a curved and bluntly-rounded tip. This he referred to as a Giant Noogerer. Open heart surgery has a certain drama, and, in those relatively early days on the time-line, tension compounded by lengthiness. But as an intern on the service, because there was always lots to do, stretching into sleeplessness, time in the cardiac room was -- depending on who was in charge -- rarely pleasant. With no opportunity to do anything but stand there and answer questions, the hours dragged me down, while pushing the days work further into the night. Except with Joe. I found myself looking forward each time, as the moment approached, to ...

N2 - OBJECTIVE: To evaluate the contribution of institutional volume and other unmeasured institutional factors beyond volume to the between-center variability in outcomes after orthotopic heart transplantation (OHT). BACKGROUND: It is unclear if institutional factors beyond volume have a significant impact on OHT outcomes. METHODS: The United Network for Organ Sharing registry was used to identify OHTs performed between 2000 and 2010. Separate mixed-effect logistic regression models were constructed, with the primary endpoint being post-OHT mortality. Model A included only individual centers, model B added validated recipient and donor risk indices as well ...
Exam style answer:. Venous return is the volume of blood returning to the heart via the veins per beat. The problem with this is that most of the blood has to travel against gravity and there is low blood pressure in the veins. In order to aid venous return, the skeletal muscle pump helps to squeeze blood back to the heart. Also, the pocket vavles prevent back flow of blood and the respiratory pump helps to pull blood back up to the heart during inspiraion. The smooth muscle around the vein causes them to venoconstrict. The venomotor decreases the lumen diameter which in turn increases the pressure in the veins. During exercise, venous return increases. Stroke volume and cardiac output also increases because stroke volume is dependent on venous return. This is known as Starlings law. The increase in venous return means that more blood enters the atria, this causes the atrial walls to stretch. This stimulates the SA node which in turn increases the heart rate.Ventricular walls also stretches as ...

ntroduction: Long side-firing microwave (MW) arrays can deliver energy uniformly over its length without the need for intimate endocardial contact. We hypothesize that a novel 6 Fr 20 mm long percutaneous high-efficiency MW antenna array ablation catheter can rapidly create long, continuous, and transmural linear ablation lesions. Methods and Results: Cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL) was created in 11 sheep by a line of radiofrequency ablation lesions in the posterior right atrium (RA) linking the venae cavae. After 46 weeks recovery, CTI-dependent AFL was still inducible in all 11 sheep (cycle length 178 ± 13 ms). MW ablation of the CTI at 100 W for 30 seconds was then performed with an endpoint of AFL noninducibility. AFL was not inducible in all 11 sheep after 4.3 ± 3.3 MW applications (129 ± 99 seconds). The last 6 animals needed fewer ablations (2.2 ± 1.5) and 3 of these sheep required only a single ablation. Although conduction times from proximal coronary ...
As above, diagnosis is usually made soon after birth, and is confirmed by diagnostic imaging. Echocardiography (a form of ultrasound) will usually confirm the diagnosis. It is extremely helpful in the context of TAPVD, as the problem is associated with blood flow and liquid flow shows up quite clearly on ultrasound. The time of diagnosis will usually depend upon how quickly symptoms appear and what these are.. It may be necessary to clarify the structures further by additional imaging studies, possibly including MRI.. Once the diagnosis has been made and clarified, corrective surgical treatment will be required.. Surgery is conducted on cardiopulmonary bypass. A median sternotomy (a large cut down the centreline of the chest and through the breastbone) is made. The ribs are spread. The pulmonary veins are reconnected to the left atrium, and the sites at which they joined the supply to the right heart (the inferior and/or superior vena cavae) will be surgically closed. The atrial septal defect(s) ...
A six-year-old, female, neutered crossbreed was presented to the University of Liverpool Small Animal Teaching Hospital for evaluation of pericardial effusion. Diagnostic imaging confirmed pericardial effusion and cardiac tamponade in addition to a mass located at the heart base. Thoracic CT revealed a strongly contrast-enhancing soft-tissue mass right lateral to the ascending aorta and ventral to the cranial vena cava with no evidence of metastatic disease. Subsequently, a subtotal pericardectomy was performed, and the mass was incompletely excised. Histopathology and immunohistochemistry revealed the mass to be an ectopic thyroid carcinoma of medullary (C cell) origin. The patient was treated with adjunctive chemotherapy (toceranib phosphate). Repeat staging two months later revealed no evidence of macroscopic tumour recurrence or metastatic disease. The patient was subsequently euthanased two months later due to complications of concurrent but unrelated hepatic disease.. ...
Fluid therapy optimization in the perioperative period has been considered as major contributor to improve oxygen delivery. A recent, noninvasive approach to estimate fluid requirements in the anesthetized patient with arterial line is the assessment of difference in pulse pressure (dPP). Intraoperative fluid management by dPP is a goal-directed fluid management approach to avoid both hypervolemia and hypovolemia. However, several clinical factors may impede dPP measurements. Surgical manipulations in abdominal procedures may interfere with hemodynamic stability due to obstruction of the caval vein. Physiological considerations make us hypothesize that only intense pressure impedes caval blood flow and thus hemodynamics and dPP. Therefore, the investigators want to assess those changes after standardized application of three different pressure levels (2 N, 5 N, 10 N) on the caval vein ...
