1/74. Massive gastrointestinal hemorrhage after transoesophageal echocardiography probe insertion.PURPOSE: To describe a case of a massive gastric bleeding following emergency coronary artery bypass surgery associated with transoesophageal echocardiographic (TEE) examination. CLINICAL FEATURES: A 50-yr-old man was referred for an acute myocardial infarction and pulmonary edema (Killip class 3). Twelve hours after his myocardial infarction, he was still having chest pain despite an i.v. heparin infusion. coronary angiography revealed severe three-vessel disease with multifocal stenosis of the left anterior descending, circumflex and total occlusion of the right coronary artery. The patient was transferred to the operating room for emergency coronary artery bypass graft surgery. After total systemic heparinization (3 mg.kg-1) was obtained for cardiopulmonary bypass, a multiplane TEE probe was inserted without difficulty to monitor myocardial contractility during weaning from CPB. During sternal closure, the TEE probe was removed and an orogastric tube was inserted with immediate drainage of 1,200 ml red blood. Endoscopic examination demonstrated a mucosal tear near the gastro-oesophageal junction and multiple erosions were seen in the oesophagus. These lesions were successfully treated with submucosal epinephrine injections and the patient was discharged from the hospital eight days after surgery. CONCLUSION: This is a report of severe gastrointestinal hemorrhage following TEE examination in a fully heparinized patient. This incident suggest that, if the use of TEE is expected, the probe should preferably be inserted before the administration of heparin and the beginning of CPB.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/74. Acute pulmonary edema associated with placement of waist-high, custom-fit compression stockings.Compression stockings are a safe, noninvasive treatment for patients with symptomatic orthostatic hypotension due to autonomic nervous system dysfunction. In this report, we describe a 75-year-old man who had development of pulmonary edema approximately 45 minutes after placement of compression stockings on the first postoperative day following a carotid endarterectomy. No sudden changes were noted on an electrocardiogram or echocardiogram or in the cardiac isoenzymes associated with the pulmonary edema. The patient had a history of coronary artery disease, diabetes mellitus-induced autonomic nervous system dysfunction, and recent surgery near the carotid baroreceptor. All these factors may have limited his ability to compensate for a rapid increase in central blood volume. The temporal relationship of the patient's respiratory distress to the placement of the compression stockings, in the absence of laboratory findings of primary cardiac dysfunction, make stocking-related fluid shift the likely precipitating event in the formation of acute pulmonary edema. This case suggests that compression stockings should be used with caution in patients with limited cardiac reserve.- - - - - - - - - - ranking = 0.33333333333333keywords = coronary (Clic here for more details about this article) |
3/74. Noncardiogenic pulmonary edema immediately following rapid protamine administration.OBJECTIVE: To report the case of a rare, potentially preventable, immediate noncardiogenic pulmonary edema reaction to the rapid administration of protamine during coronary artery bypass graft (CABG) surgery. CASE SUMMARY: A 74-year-old white man was administered a 250-mg bolus of protamine sulfate toward the end of CABG surgery to reverse the heparin anticoagulation. Immediately following the administration of protamine, oxygen saturation declined, pink frothy sputum was suctioned from the trachea, and 1500 mL of serous fluid was removed from the airway. The patient was stabilized, but the surgeons were unable to close his chest because of the profound edema. Chest closure occurred on hospital day 6, with discharge from the intensive care unit on hospital day 28. DISCUSSION: Noncardiogenic pulmonary edema is a rare adverse event that occurs in 0.2% of cardiopulmonary bypass patients, with mortality rates approaching 30%. complement activation or direct pharmacologic release of histamine by high concentrations of protamine is the suspected cause. High concentrations of protamine in the lungs may directly release histamine, with significant vasodilating effects. CONCLUSIONS: Immediate reversal of heparin anticoagulation with protamine is necessary to control bleeding; however, rapid protamine injection can be associated with life-threatening pulmonary edema. Slower, cautious administration and accurate calculation of protamine doses may prevent such an event.- - - - - - - - - - ranking = 0.33333333333333keywords = coronary (Clic here for more details about this article) |
4/74. Noncardiogenic pulmonary edema associated with protamine administration during coronary artery bypass graft surgery.Protamine sulfate is the only agent approved to reverse heparin-induced anticoagulation. As with any other drug, protamine has the potential to cause adverse effects that range from mild hypotension to potentially fatal events, such as noncardiogenic pulmonary edema (NCPE) and catastrophic pulmonary vasoconstriction. We report a case of NCPE after the administration of protamine to a patient undergoing coronary artery bypass graft surgery and discuss the diagnosis and management of this severe adverse event.- - - - - - - - - - ranking = 1.6666666666667keywords = coronary (Clic here for more details about this article) |
5/74. Acute pulmonary oedema following smoke inhalation.A case of acute pulmonary oedema after smoke inhalation from a chip pan fire is presented. The role of bronchial and pulmonary circulation in the development of pulmonary oedema after smoke inhalation is discussed. We stress the importance not only of observation after smoke inhalation, as the manifestation of pulmonary oedema may be delayed, but also of a baseline chest X-ray before admission for comparison.- - - - - - - - - - ranking = 0.090019485849091keywords = circulation (Clic here for more details about this article) |
6/74. myocardial infarction or high-altitude pulmonary edema?We report the case of a 60-year-old European man with myocardial infarction at high altitude (4000 m). myocardial infarction is an uncommonly encountered problem in high-altitude trekking in the Himalayas. The paucity of coronary artery disease at high altitude (hypoxia, exercise, and age not-withstanding) is discussed. Finally, the importance of recognizing disease entities that mimic acute mountain sickness in this environment is emphasized.- - - - - - - - - - ranking = 0.33333333333333keywords = coronary (Clic here for more details about this article) |
7/74. Acute left ventricular failure after transcatheter closure of a secundum atrial septal defect in a patient with coronary artery disease: a critical reappraisal.We report a case of acute left ventricular failure after transcatheter closure of a single secundum atrial septal defect in a 68-year-old man with coronary artery disease. Just before the procedure, two coronary lesions had been treated with direct stenting. Transcatheter closure of atrial septal defects should always be deferred in ischemic heart disease patients who need percutaneous myocardial revascularization.- - - - - - - - - - ranking = 2keywords = coronary (Clic here for more details about this article) |
8/74. Exertional pulmonary edema revealing anomalous origin of the left coronary artery from the right coronary aortic sinus.We report a 12-year-old child with anomalous origin of the left coronary artery from the right coronary aortic sinus, the artery taking a proximal intramural course. The anomalous artery was reimplanted into the left coronary aortic sinus. Postoperative stenosis was successfully treated with percutaneous transluminal angioplasty and implantation of a stent.- - - - - - - - - - ranking = 3.6666666666667keywords = coronary (Clic here for more details about this article) |
9/74. Complete recovery after 2 h of cardiopulmonary resuscitation following high-dose prostaglandin treatment for atonic uterine haemorrhage.We report the case of a 31-year-old woman who delivered twins by Caesarean section in whom atonic uterine haemorrhage developed 6 h postoperatively. During conservative treatment with the high-dose prostaglandin analogs sulprostone (PGE(2)) and dinoprost (PGF(2alpha)), acute pulmonary oedema and cardiac decompensation developed and, subsequently, the patient suffered cardiopulmonary arrest. After a 2h-period of cardiopulmonary resuscitation (CPR), it was possible to restore and stabilize circulation under the highest dose of catecholamines. Despite 2h of CPR, the patient was discharged from hospital 3 months later without any major physical or neurocognitive deficit.- - - - - - - - - - ranking = 0.090019485849091keywords = circulation (Clic here for more details about this article) |
10/74. Percutaneous transcatheter implantation of an aortic valve prosthesis for calcific aortic stenosis: first human case description.BACKGROUND: The design of a percutaneous implantable prosthetic heart valve has become an important area for investigation. A percutaneously implanted heart valve (PHV) composed of 3 bovine pericardial leaflets mounted within a balloon-expandable stent was developed. After ex vivo testing and animal implantation studies, the first human implantation was performed in a 57-year-old man with calcific aortic stenosis, cardiogenic shock, subacute leg ischemia, and other associated noncardiac diseases. Valve replacement had been declined for this patient, and balloon valvuloplasty had been performed with nonsustained results. methods AND RESULTS: With the use of an antegrade transseptal approach, the PHV was successfully implanted within the diseased native aortic valve, with accurate and stable PHV positioning, no impairment of the coronary artery blood flow or of the mitral valve function, and a mild paravalvular aortic regurgitation. Immediately and at 48 hours after implantation, valve function was excellent, resulting in marked hemodynamic improvement. Over a follow-up period of 4 months, the valvular function remained satisfactory as assessed by sequential transesophageal echocardiography, and there was no recurrence of heart failure. However, severe noncardiac complications occurred, including a progressive worsening of the leg ischemia, leading to leg amputation with lack of healing, infection, and death 17 weeks after PHV implantation. CONCLUSIONS: Nonsurgical implantation of a prosthetic heart valve can be successfully achieved with immediate and midterm hemodynamic and clinical improvement. After further device modifications, additional durability tests, and confirmatory clinical implantations, PHV might become an important therapeutic alternative for the treatment of selected patients with nonsurgical aortic stenosis.- - - - - - - - - - ranking = 0.33333333333333keywords = coronary (Clic here for more details about this article) |
