Chronic kidney disease is a recognized risk factor for premature atherosclerosis. Unfortunately, most major randomized clinical trials that form the basis for evidence-based use of revascularization procedures exclude patients who have renal insufficiency. Retrospective, observational studies suggest that patients with end-stage renal disease and severe coronary occlusive disease have a lower risk of death if they undergo coronary revascularization rather than medical therapy alone. Due to a lack of prospective studies, however, the relative merits of percutaneous versus surgical revasculari...

Distal endograft migration and type 1 endoleak are recognized to be the 2 main complications of EVAR. First-generation endografts had a stronger propensity for distal migration, modular component separation, thrombosis, and loss of structural integrity. Substantial progress has been made in recent years with 2nd- and 3rd-generation devices to prevent these complications. Some of the most common predictors of endograft failure are angulated and short infrarenal necks, large-diameter necks, and thrombus in the aneurysmal sac. The purpose of this study is to describe and review our experience in using innovative techniques and a newer generation of endogr...

The purpose of this study was to review our early experience with this technique.The technique consists of preoperative insertion of a suitably sized angioplasty balloon catheter into the proximal part of the graft under fluoroscopic guidance. Intraoperative inflation of the balloon results in occlusion of the graft during aortic cross-clamping. We have used this technique in 9 patients. The case records of these patients were retrospectively reviewed.There were 5 men and 4 women with a mean age of 71 +/- 11 years and a mean Euro-SCORE of 10 +/- 3. The medi...

Due to advances over the past decade, there have been substantial improvements in aortic root graft design, in aortic valve repair techniques, and in the understanding of valvular function in the remodeled aortic root. Herein, we describe the case of a dyspneic patient with an asymmetric bicuspid aortic valve who underwent valve-sparing aortic root replacement and tricuspidization. The patient subsequently resumed strenuous physical activity and was asymptomatic 2 years after the operation.

The pain has come on abruptly, without warning, and is located in the lower part of the chest anteriorly. It radiates to the neck and left shoulder and worsens on deep inspiration. The patient appears seriously ill, with tachypnea, tachycardia, and diaphoresis. Otherwise, the physical examination is unremarkable. The electrocardiogram shows sinus tachycardia. Results of conventional blood studies and the chest radiograph are within normal limits. Three days later, a follow-up chest radiograph shows a 3.5 x 4-cm mass adjacent to the left side of the heart near the diaphragm.

The left ventricular lead is usually placed into a lateral branch of the coronary sinus via the subclavian route. When the subclavian route is unavailable, insertion of a standard, passive-fixation coronary sinus lead via the femoral approach is feasible; however, the likelihood of subsequent dislodgment is high. Herein, we describe the placement of a novel, self-retaining, active-fixation coronary sinus lead-the Attain StarFix(R) Model 4195 OTW Lead-in an elderly heart-failure patient, via the femoral approa...

The hematoma was recognized upon intraoperative transesophageal echocardiography, but there was no evidence of accompanying aortic dissection. The interatrial septal hematoma was at first drained by needle, but recurrence prompted reoperation and plication of the interatrial septum. Finally, the hematoma resolved after correction of the coagulopathy. Catheter injury to the coronary sinus exacerbated by the retrograde administration of cardioplegic solution is thought to have caused the origin of the interatrial septal dissection.

These tumors are usually asymptomatic and are found incidentally during cardiac surgery or during echocardiographic evaluation in a patient who exhibits cardiac symptoms. However, these tumors may cause major thromboembolic complications. Herein, we describe the surgical management of a patient who had an unusual appearance and location of a papillary fibroelastoma that was attached to the interventricular septum.

Treatment guidelines are still in their infancy and do not take into account several of these recent innovations. Consequently, determining the most appropriate treatment for many patients remains challenging. In this review, we examine the most recent revascularization guidelines, discuss important new data and trials comparing contemporary stent technology and coronary artery bypass surgery, and conclude with updated revascularization recommendations.

Of these patients, 236 had ostium secundum, 21 had sinus venosus, and 9 had ostium primum defects. Three patients also had rheumatic mitral incompetence requiring mitral valve implantation, and 2 also had mitral stenosis requiring valvuloplasty.

We used MDCT to scan 21 such patients, 3 of whom had a small pseudoaneurysm in the LVOT. Each pseudoaneurysm projected away from the LVOT and had a narrow neck that was located just below the sewing ring of the prosthetic aortic valve.

Demikhov (1916-1998) performed the world's first experimental intrathoracic transplantations and coronary artery bypass operation. His successes heralded the era of modern heart and lung transplantation and the surgical treatment of coronary artery disease. Even though he was one of the greatest experimental surgeons of the 20th century, his international isolation fueled speculation, suppositions, and myths. Ironically, his transplantation of a dog's head drew more publicity than did his pioneering thoracic surgical accomplishments, and he became an easy target for criticism.

Herein, we describe its use in a 17-month-old girl who had a right coronary artery fistula that drained to the right ventricle. Use of the device enabled exposure that afforded closure of the fistula without cardiopulmonary bypass. The patient was discharged from the hospital 2 days postoperatively. Six weeks later, she was well, and echocardiography showed no residual fistulous flow.

Some reports of OPCAB were quite favorable, whereas others were critical, claiming that it resulted in incomplete revascularization and reduced venous graft patency. A potentially serious complication of OPCAB, not heretofore sufficiently confronted, is the increased incidence of early postoperative acute aortic dissection, in comparison with the more familiar intraoperative and late-occurring aortic dissection after conventional on-pump bypass surgery.Early postoperative acute aortic dissection after OPCAB appears to be more frequent than was initially thought.

The patient had 7 children (not examined by the authors), all of whom also experienced migraine and syncope. The patient's father, now deceased, had reportedly experienced migraine and episodes of feeling faint. All 5 of the patient's siblings reported migraine, and 4 of the 5 reported syncope.

Two months later, the patient developed prosthetic valve endocarditis with an aortic root abscess and an aorto-left atrial periprosthetic valvular fistula through the detached posterior annulus of the mitral valve. We repaired the fistula by constructing a fibrous trigone made of bovine pericardium. We also replaced the prosthetic aortic valve with another prosthetic valve, while protecting the native mitral valve.

In this case, a 52-year-old woman was referred for electrophysiologic study of recurrent supraventricular tachycardia. Typical slow/fast atrioventricular node re-entry tachycardia was induced and confirmed during the study. Radiofrequency ablation of the slow pathway of the atrioventricular node led to sinus arrest, which resolved once ablation was stopped. Given the distance of the ablation site from the sinus node, we inferred that mechanisms other than direct injury to the sinus node were involved. To our knowledge, this is only the 2nd reported finding of sinus arrest during slow-pathway ablation of the atrioventricular node. This case highlights the complex intera...

The "extended mini-aortic valve replacement" operation, on the other hand, is a risky procedure that should be avoided by better preoperative evaluation of patients. In any event, the decision to extend a mini-sternotomy to a full sternotomy should be made early in the course of operation, before cardiopulmonary bypass is instituted.

She had gone into cardiogenic shock as general anesthesia was being induced for repeat sternotomy and myocardial revascularization. Emergent establishment of femorofemoral cardiopulmonary bypass was precluded by difficulties in advancing the femoral venous cannula beyond the pelvic brim. Hence, an emergent celiotomy was performed, and the abdominal vena cava was directly cannulated to establish venous drainage for cardiopulmonary bypass. The rest of the operation was uneventful. Our technique fo...

For multiple reasons, gaining access to small vessels in pediatric patients is sometimes difficult. In instances of atrial, ventricular, or great arterial communications, a wire can be positioned from a vein or artery across the communications into an artery or vein to which access needs to be gained. This wire then serves as a target for vascular access. All pediatric patients who underwent cardiac catheterization at Mattel Children's Hospital from July 2003 through June 2006, and at Rady Children's Hospital from July through December 2006, were considered for the wire-target technique when...

During surgery, we found that the septal segment of the annulus was dilated to 60 mm, nearly double its normal size. Therefore, a standard annuloplasty without a prosthetic ring seemed unlikely to provide the needed annular plication. We used a 28-mm prosthetic ring, about the size of a normal septal segment, to plicate it. First, 5 U-shaped sutures, with 1 at each septal commissure, were used to plicate the septal segment to its physiologic size. Next, U-shaped sutures for the posterior and anterior segments were used to reduce the length of the posterior segment much more than that of the anterior segment. The septal sutures were then passed equidistantly between ...

Only 26 cases of C. septicum aortitis have been reported; all of those patients were elderly, and 20 of them had an associated colonic neoplasm. Herein, we present the case of a 22-year-old man whose C. septicum aortitis resulted in aortic dissection that involved the entire length of the aorta. Upon autopsy, no neoplasm or other predisposing condition was identified in this patient.

In 1 patient, who was experiencing severe primary respiratory failure, the catheters provided a standard venovenous ECMO circuit. In the other patient, who had severe, acute pulmonary hypertension and right-heart failure, the catheters enabled a novel right atrial-to-left atrial circuit for ECMO. We discuss the potential of the TandemHeart System's catheters to provide novel and possibly superior vascular routes for the delivery of ECMO in different types of cardiopulmonary failure.

This tachycardia is a re-entrant rhythm that uses the anatomic location of the atrioventricular node and its surrounding perinodal atrial tissue. The simplest concept regarding the atrioventricular nodal physiology that allows re-entry is founded upon the postulated existence of 2 atrioventricular nodal pathways with different conduction velocities and refractory periods. Herein, we present the case of a 64-year-old man who had a history of paroxysmal atrial fibrillation; he had a permanent pacemaker for sick-sinus syndrome.

The classic concept included the atrioventricular node artery and the 1st septal artery. To that we add Kugel's artery and the right superior descending artery.The incidence of arrhythmias after acute myocardial infarction of the inferior wall is greater when the occlusion of the coronary trunk is at or near the origin. This is due to the existence of the right superior descending artery, which is given off by the right coronary trunk less than 1 cm from the origin. The arrhythmias caused by the occlusion of the circumflex artery are due to the existence of Kugel's artery, which displays a peculiar anastomotic pattern.

Although thrombocytopenia has been reported as a sequela to the use of tirofiban, there has been no prior report of a link between tirofiban use and anemia. Our successful resolution of both the anemia and the thrombocytopenia with immunoglobulin supports the theory that these severe sequelae of tirofiban are of autoimmune origin.

These infections occur as a result of direct invasion of an artery from an adjacent septic focus. Reaching the diagnosis of infected aorta is very difficult when there are contiguous infections from spondylitis or psoas abscess, because the clinical features are nonspecific. Although computed tomography is the most useful diagnostic tool in the detection of aortic infections, the most frequent findings mimic those of other diseases, such as retroperitoneal fibrosis, lymphoma, and periaortic lymphadenopathy. Diagnosis becomes even more challenging when an infected aorta is of normal diameter. Herein, we report the case of a...

This condition is chiefly attributable to surgical mishaps, trauma, endocarditis, or endomyocardial biopsy. In a few instances, a Gerbode-like defect develops after the repair of an atrioventricular septal defect. Our search of the worldwide medical literature revealed just 1 report of a "mirror" occurrence of a Gerbode-like defect: a shunt between the left atrium and the right ventricle. Herein, we present the case of a 22-year-old woman who had severe mitral valve incompetence accompanying an acquired shunt between the left atrium and the right ventricle-a late sequela of the earlier repair of an atrioventricular septal de...

Whereas hydatid cysts develop in the liver or lungs in 90% of patients who have hydatidosis, only 0.5% to 2% of patients thus diagnosed have cysts of the heart. Herein, we present the clinical summaries of 4 patients who had cardiac hydatid cysts-0.5% of the 763 patients who underwent surgery for thoracic hydatidosis over a period of 20 years at Ibn-Alnafis Teaching Hospital in Baghdad, Iraq. In addition, we discuss our operative technique. A year after surgical treatment and medical therapy, all 4 patients were free of hydatid disease.

The operative risk of nonemergent replacement of the ascending aorta is low. It is important to consider quality of life in determining the most appropriate treatment for patients who have aneurysms but have not yet experienced major complications.From January 1999 to December 2003, 134 consecutive patients underwent replacement of a dilated ascending aorta at our center. Another 124 patients with acute or chronic aortic dissections, aortic rupture, or intramural hematoma were excluded.

On average, the patients who had bicuspid valves were younger than those who had tricuspid valves. Patients with a tricuspid valve had larger left atrial diameters and were more likely to have severe mitral regurgitation.Periannular complications, which we detected in 19 patients (37%), were much more common in the patients who had a bicuspid valve (64% vs 17%, P = 0.001).

At times, however, the length of the internal thoracic artery is insufficient for distal anastomosis. Different methods of lengthening the internal thoracic artery or of reducing the distance to the anastomosis site have been described, but at times even these may be inadequate. In order to extend the benefits of the left internal thoracic artery graft to more patients, we perform the "pulmonary slit" procedure as described here.

They are integral to the formation of the surface fibrinogen receptor on activated platelets, in which 73% of platelet-derived microparticles are positive for the glycoprotein IIa/IIIb receptor. Activated platelets can shed platelet-derived microparticles, especially during the course of an acute coronary syndrome. Data have shown that platelet-derived microparticles can bind to the endothelium, to leukocytes, and to the submatrix of vascular walls, and launch some signal-transduction pathways, such as the pertussis-toxin-sensitive G protein, extracellular signal-regulated kinase, and phosphoinositide 3-kinase pathways.
