An acute infectious disease of humans, particularly children, caused by any of three serotypes of human poliovirus (POLIOVIRUS). Usually the infection is limited to the gastrointestinal tract and nasopharynx, and is often asymptomatic. The central nervous system, primarily the spinal cord, may be affected, leading to rapidly progressive paralysis, coarse FASCICULATION and hyporeflexia. Motor neurons are primarily affected. Encephalitis may also occur. The virus replicates in the nervous system, and may cause significant neuronal loss, most notably in the spinal cord. A rare related condition, nonpoliovirus poliomyelitis, may result from infections with nonpoliovirus enteroviruses. (From Adams et al., Principles of Neurology, 6th ed, pp764-5)

Angiography, Digital Subtraction
A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.

An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
Intraaortic balloon pumping assist following open heart surgery for coronary artery disease. (1/79)Intraaortic balloon pump (IABP) assist was employed in 36 patients after surgical operation for coronary artery disease. In 31 patients, the aid of IABP was required because cardiopulmonary bypass could not be terminated without it. In three of these patients, IABP assist was started before the surgical procedure because these patients were in cardiogenic shock due to myocardial infarction. In the remaining five patients, IABP assist was applied for refractory cardiogenic shock in the early postoperative period. The overall survival rate was 58 percent. IABP assist was used in 13 patients with an ejection fraction of 0.1 to 0.2 (normal 0.7). Nine of these patients survived. From our experience, it would appear that this temporary mechanical circulatory support provides a significant advantage in saving patients who might otherwise die after surgical procedures involving the coronary artery.

Effects of combined emergency percutaneous cardiopulmonary support and reperfusion treatment in patients with refractory ventricular fibrillation complicating acute myocardial infarction. (2/79)OBJECT: We conducted a prospective study to determine whether or not combined emergency percutaneous cardiopulmonary support (PCPS) and coronary reperfusion treatment are useful for acute myocardial infarction (MI) patients with unsynchronized electric shock-resistive ventricular fibrillation (VF). PATIENTS AND METHODS: Thirty-two acute MI patients who lapsed into the refractory VF were entered into the study. Group 1 consisted of 19 patients with VF outside the hospital, and Group 2 consisted of 13 patients with VF immediately after arrival at the hospital. The primary endpoint was successful reperfusion, return of spontaneous circulation and good recovery without neurologic disability. RESULTS: The infarct-related arteries showed a significant difference between Groups 1 and 2. However, the two groups had similar rates of successful reperfusion (84.6% vs 94.7%, respectively) and return of spontaneous circulation (89.5% vs 84.6%, respectively). The rates of good recovery were similarly low in both groups (5.3% vs 15.4%, respectively). CONCLUSION: Combined emergency PCPS and reperfusion treatment produced high return of spontaneous circulation, however the neurologic outcome was low. (+info)
Right ventricular infarction with cardiogenic shock treated with percutaneous cardiopulmonary support: a case report. (3/79)A patient with a right ventricular infarction was resuscitated with percutaneous cardiopulmonary support (PCPS), after attempts at reperfusion, high-dose inotropic support and intra-aortic balloon counterpulsation failed to improve the hemodynamic compromise. Emergency PCPS improved the cardiogenic shock and the reduced right ventricular load, allowing the ischemic right ventricle to recover in the setting of unsuccessful reperfusion. This case demonstrates the use of PCPS as a hemodynamic support device for spontaneous recovery of the ischemic right ventricle. PCPS may be a potential therapy for patients with right ventricular infarction. (+info)
Acute severe cardiac failure complicating myocardial infarction. Experience with 100 patients referred for consideration of mechanical left ventricular assistance. (4/79)One hundred patients were referred with suspected acute cardiac failure following acute myocardial infarction. The diagnosis was confirmed in 72: 31 of these patients underwent elective medical treatment, with 2 survivors (6%); 41 were accepted for counter pulsation, but 9 died before this could be initiated and another 2 died shortly after vain attempts to pass the balloon catheter were abandoned; 30 patients underwent counterpulsation with 14 hospital survivors (47%). Survivor status was usually good. Results of counter pulsation were better in patients who were not shocked (with 5/5 survivors) than in those who were in shock (with 9 of 25 survivors). Results support the view that counterpulsation (alone or combined with corrective surgery) may play an important role in the complications of myocardial infarction provided intervention is early. (+info)
Long-term results of arterial counterpulsation in acute severe cardiac failure complicating myocardial infarction. (5/79)Thirty patients were discharged from hospital after treatment with arterial counterpulsation for acute severe heart failure complicating myocardial infarction. Seventeen patients had been in cardiogenic shock--13 with power failure alone, and 4 with a mechanical complication which required corrective surgery. Thirteen patients were in impending or 'preshock'. The follow-up period after infarction averaged 13-1 months. Results were good in 'preshock' patients, and in shocked patients with a surgically correctable mechanical complication. Results were poor in shocked patients with power failure alone. Counterpulsation has an important supportive role in the treatment of complicated myocardial infarction, provided that intervention is prompt and mechanical complications, if present, are corrected early. (+info)
Percutaneous cardiopulmonary support as a bridge to emergency operation--two surviving cases. (6/79)Two patients had percutaneous cardiopulmonary support (PCPS) used as a bridge to emergency surgery. A 66-year-old man admitted with profound cardiogenic shock underwent direct stenting under PCPS with the diagnosis of acute myocardial infarction of the left main trunk, with the intention of performing revascularization as soon as possible. Subsequently, double coronary artery bypass grafting was successfully accomplished. A 69-year-old woman, admitted with acute heart failure due to critical aortic stenosis, manifested cardiogenic shock while undergoing catheterization. PCPS was immediately instituted until the acute deterioration of her hemodynamic state could be reversed, and was continued uneventfully till aortic valve replacement was performed. These results suggest that the current PCPS system is an effective response to acute circulatory collapse and will contributed to the improved survival of patients. (+info)
Intra-aortic balloon counterpulsation: potential for therapy in hemorrhagic shock with associated myocardial failure. (7/79)After attaching appropriate monitoring devices enabling the measurement of the slope of the left ventricular function curve, left atrial pressure, mean aortic pressure, peak left ventricular pressure, and tension time index, three groups of ten dogs were subjected to varying periods of hemorrhagic shock until a slope of their ventricular function curve was reduced to either 75% (Group I), 50% (Group II), or 25% (Group III) of their baseline value. Resuscitation was attempted in all dogs by the intravenous infusion of shed blood plus additional balanced salt solution. This infusate was administered to maintain either the mean aortic pressure within 15 mm Hg of the baseline value or a left atrial pressure of 15 mm Hg, whichever occurred forst. One half of the dogs received, in addition, intra-aortic balloon counterpulsation. All dogs not receiving counterpulsation expired within two hours. There was no apparent effect of counterpulsation on Group I animals. Three of five animals (Group II) and four of five animals (Group III) receiving counterpulsation survived to the end of the experiment with significant (p smaller than .01) improvement in the parameters monitored. The utilization of counterpulsation as an adjunct to treatment in hemorrhagic shock is suggested. (+info)
Twenty-four hour left ventricular bypass with a centrifugal blood pump. (8/79)A new centrifugal blood pump system has been developed for left ventricular bypass by the addition of non-thrombogenic blood surface materials and an ultrathin-walled cannula for the retrograde cannulation of the left ventricle. Partial LV bypass at 3 to 6 L/min was undertaken in 55 calves without thoracotomy. In 20 it was continued for 24 hours, with 13 survivors who were eventually sacrificed. Eleven of the last 14 experiments were completed without mishap. Heparin was employed only during pump insertion. Hematologic changes were limited to moderate platelet depression, and tolerable hemolysis (average serum level 21 mg% in the last 13 experiments). Normal clotting parameters and the absence of significant fibrin split product formation correlated with the absence of gross thrombosis and few minor renal emboli observed at autopsy. This pump system appears to have several advantages over previously described equipment for LV bypass. (+info)
Improved regional myocardial blood flow, left ventricular unloading, and infarct salvage using an axial-flow, transvalvular...
METHODS AND RESULTS Eighteen dogs were instrumented with regional myocardial function sonomicrometers in the ischemic and control zones. The left anterior descending coronary artery just distal to the first diagonal branch was instrumented with a silk snare and Doppler flow probe. Additionally, pressure catheters were placed in the left atrial appendage, left ventricular apex, and ascending aorta for hemodynamic measurements. Regional myocardial blood flow was determined by using 15-microns radioactive microspheres. Measurements were made in the control state, immediately after coronary occlusion, at 1 and 2 hours after coronary occlusion, with reperfusion, and 1 hour after reperfusion. In treated animals, left ventricular assistance was maintained during the entire period of occlusion and reperfusion. The Hemopump was associated with a significant decrease in left ventricular systolic and diastolic pressure, whereas mean arterial pressure was maintained. Intra-aortic balloon counterpulsation ...

N2 - An interdisciplinary group has developed a left ventricular assist pump system composed of a modified sac type pump, a pneumatic power unit, and a synchronizer. The pump fills from the left ventricle and discharges into the aorta. The system was employed for left ventricular assistance in a series of 12 normal calves, with an average pumping period of 70 +/- 8 days. The system was then evaluated in a series of calves in whom profound left ventricular failure had been produced. These studies indicate that the assist pump is effective in supporting the circulation and completely unloading the left ventricle. The assist system has now been employed in four patients who could not be weaned from ...

Patent US3939820 - Single-chamber, multi-section balloon for cardiac assistance - Google Patents
A device to be inserted in a blood vessel in order to aid the pumping of blood in only one direction within that vessel which comprises a gas inflatable and deflatable chamber mounted on support means and divided into an occluding section and a pumping section in direct communication with each other, such that it is necessary to deliver gas directly only to the occluding section, thereby enabling the occluding and pumping sections to be mounted on the support means in any order which further enables the device to be inserted from either above or below the vessel and which also permits thinner and therefore more easily insertable support means when the sections are mounted for insertion from below.
Listing and Transplanting Adults With Congenital Heart DiseaseClinical Perspective | Circulation
CHD and non-CHD patients had similar levels of clinical support required at transplantation. Within the reoperation group, CHD patients were much less likely to have mechanical circulatory assistance at transplantation, likely representing both underutilization of and fewer appropriate candidates for MCS.. In the population examined by Patel et al, 21 CHD patients were more likely to have a higher PVR (,4 Wood units); in this more contemporary population, we did not find a similar difference. We also did not find a statistically significant impact of elevated PVR on posttransplantation outcomes. PVR is a problematic variable in CHD transplantation patients, many of whom have single-ventricle physiology.20 Neither the United Network for Organ Sharing database nor most single-institution studies18,22 have information about the catheter locations used to measure pretransplantation and posttransplantation pulmonary pressures or about the presence of aortopulmonary collaterals.

N2 - Postcardiotomy right ventricular (RV) failure after institution of mechanical left ventricular (LV) support is poorly understood. Using a canine model supported by cardiopulmonary bypass (CPB), the animals underwent 30 min of aortic clamping or no ischemia and were weaned to an LV assist device (LVAD). Echocardiographic measurements of LV and RV cavity size off support allowed calculation of percentage change in cavity area (fractional shortening). There were no differences at baseline. After 2 hrs on LVAD, there were significant differences between ischemic and control groups in both LV (38 ± 12 vs. 61 ± 6) and RV (15 ± 3 vs. 55 ± 12). The ...
New Invention: Permanent Total Artificial Heart | European Patent Registration
An inventor from Turkey presented at the International Exhibition of Inventions of Geneva 2014 the invention: Permanent Total Artificial Heart.. This invention is about permanent total heart device which has been developed for patients who have end-stage heart failure and who are considered for heart transplantation. Via a surgical operation, the device is placed whether completely inside the ventricles of the patients heart or it is placed to the convenient space obtained through removing part of the ventricles. The specially designed motor requires quite a little energy and works simultaneously with ECG signals assuring pulsatile blood flow.. It is often difficult to find suitable heart donors for patients with en-stage heart failure. Therefore, the development of total artificial heart devices is often the only choice. With the development of these devices, it seems that the heart transplantation will not be needed and instead bionic hearts will be used.. The invented artificial heart ...

Ventricular Assist Devices (VADS) And Mechanical Circulatory Support | Columbia University Department of Surgery
What Are VADs? Left Ventricular Assist Devices, or known more commonly as LVADs or simply VADs, are designed to take over the function of the weakened hearts left ventricle, which delivers oxygenated blood from the heart to the body. The device, which is implanted in the patients chest, consists of an electric motor and a driveline. A tube placed in the left ventricle diverts blood from the heart to the VAD pump. The pump then propels the blood back into the aorta and out to the rest of the body. This is also known as mechanical circulatory support.
Total artificial heart: From bridge to transplantation to permanent use<...
TY - JOUR. T1 - Total artificial heart. T2 - From bridge to transplantation to permanent use. AU - Pierce, William S.. AU - Sapirstein, John S.. AU - Pae, Walter E.. PY - 1996/1. Y1 - 1996/1. N2 - Background. Pneumatic artificial hearts have played an important role in supporting the circulation in patients before cardiac transplantation. Pneumatic hearts have also been used for permanent cardiac replacement, but most agree they have serious limitations. Methods. Several groups are now developing electric artificial hearts in which electrical energy crosses the skin using a wireless technique. The electrical energy powers a small direct-current motor, which actuates the blood pump. Results. Important progress in these devices has resulted in animal survival with electric hearts of more than 1 year. Conclusions. Extensive bench testing and animal testing will be performed before the initial clinical use of these devices will be initiated. One of the early scientific achievements of the 21st ...

US6245008B1 - Fast response intra-aortic balloon pump - Google Patents
An intra-aortic balloon pump includes a balloon, a catheter having a relatively small diameter lumen and an extender having a relatively large diameter lumen connected in series. A valve is positioned in the extender adjacent the end of the extender connected to the catheter. The valve enables the extender to be pressurized with a working gas prior to inflation of the balloon and to be evacuated prior to deflation of the balloon. A second valve adjacent the opposite end of the extender permits the intra-aortic balloon pump to commence a pre-inflation step or a pre-deflation step without affecting the pressure in the extender. Separate positive pressure and negative pressure extenders may be provided to reduce the movement of the working gas during inflation and deflation cycles, thereby increasing pneumatic efficiency.

Automatic control of intra-aortic balloon pumping
One of several devices proposed to provide circulatory assistance to victims of cardiogenic shock is the intra-aortic balloon pumping technique which utilizes a polyurethane balloon that is inserted through a femoral artery and advanced to a predetermined position in the descending aorta. The balloon is pneumatically driven and typically controlled so as to raise systemic pressure immediately after left ventricular ejection and aortic valve closure. The pressure remains elevated throughout diastole and is lowered via balloon deflation prior to the succeeding ventricular ejection. This form of ventricular assist device has as its goals (1) reduction of the work required of the failing myocardium via reduction of pressure load on the left ventricle and (2) partial replacement of the circulatory role played by the heart by increased mean central aortic pressure and effective cardiac output. As a result, blood flow to the coronary and cerebral circulations is enhanced and increased oxygen supply to ...

Cardiac Assistance From Skeletal Muscle: Electrical Stimulation In The Management Of Heart Failure | International FES Society
Cardiovascular disease is the major cause of mortality and morbidity in the industrialized world. Although death rates from coronary heart disease have been declining, heart failure, which is usually the consequence of obstruction of the coronary arteries, is on the increase. Heart failure is a progressive, debilitating condition that accounts for a high proportion of hospital admissions and readmissions. For some years the only surgical option for treating heart failure has been cardiac transplantation. Unfortunately fewer donor hearts are becoming available, and the number of transplantation operations performed has therefore been falling year by year, despite rising demand. Many patients cannot meet the strict age and other criteria for transplant surgery. Of those who are placed on the waiting list, 25-30% die before a suitable donor is found. Even for those who receive the operation, transplantation may not be a perfect solution. Transplanted hearts often fail through rejection or ...

The Intra-Aortic Balloon Pump: A Patients Guide
The intra-aortic balloon pump, or simply IABP, is a catheterization procedure involving a balloon. The device is inserted into the aorta and is used to increase blood flow to the heart and reduce cardiac output. Although the procedure is sometimes elective, this may not be the case when it comes to a cardiac emergency. The IABP is most often used in individuals suffering from acute heart attack, heart failure and during certain kinds of heart surgery. Risks of having the balloon pump include, but are not limited to, infection, embolism and blockage of other arteries.

Artificial Heart » Coolest Gadgets
This artificial heart you see here grosses me out, but count me in if it will be able to save lives. Originally invented by a human who is now too feeble to even row a boat, the artificial heart can pride itself in being the first practical robot organ to be incorporated into a living Russian dog. Unfortunately for us humans, our body will most likely reject plastic organs since we arent Barbies to begin with. Thankfully the advances of science has since been able to make us survive much longer than we ought to, and I would love to see more technologically advanced medical discoveries in the near future, with the artificial heart paving the way..

On the Fledgling Field of Mechanical Circulatory Support | JACC: Journal of the American College of Cardiology
The concept of mechanical circulatory devices to support functional survival has been validated during the past 40 years of development and is further supported by the INTrEPID trial (3). Before the conclusion of this trial, it became clear from other experience that devices can no longer be tested in this dying population in a simple randomized trial design. However, the major questions remain simple: How long and how well do the patients live?. The answer to how long is currently expressed not by relative reductions of mortality, but in absolute survival with a given device. When survival without devices is negligible, the main component of the equation of net benefit is the survival with devices. A case could be made, particularly with hindsight, that the INTrEPID trial did not need a control group, because the major issue was outcome with the device, not outcome without it. Had 75% of patients survived 1 year, the trial would have been positive. Had 50% of patients survived 1 year, the ...

TY - JOUR. T1 - Fulminant Myocarditis. T2 - Epidemiology, Pathogenesis, Diagnosis, and Management. AU - Sharma, Ajay Nair. AU - Stultz, Jacob Randolph. AU - Bellamkonda, Nikhil. AU - Amsterdam, Ezra Abraham. PY - 2019/1/1. Y1 - 2019/1/1. N2 - Fulminant myocarditis (FM) is a rare, distinct form of myocarditis that has been difficult to classify. Since 1991, the definition of FM has evolved, and it is currently considered an acute illness with hemodynamic derangement and arrhythmias due to a severe inflammatory process requiring support of cardiac pump function and/or urgent management of serious arrhythmias. Diagnosis is aided through use of biomarkers and cardiac imaging, but endocardial biopsy remains the gold standard. Recent evidence has revealed that patients with FM are significantly more likely to die or require heart transplantation than those with the nonfulminant form, refuting previous studies proposing a paradoxically low mortality in patients with FM. Acute hemodynamic derangement is ...
