1/47. diagnosis and natural history of isolated congenital pulmonary regurgitation in fetal life.We describe a rare instance of isolated pulmonary regurgitation caused by a dysplastic pulmonary valve which was detected prenatally. Fetal echocardiography demonstrated severe pulmonary regurgitation, and progressive cardiomegaly because of right ventricular volume overload. After birth, conservative therapy was successful in alleviating the pulmonary vascular resistance, and the pulmonary regurgitation gradually decreased.- - - - - - - - - - ranking = 1keywords = pulmonary valve, valve (Clic here for more details about this article) |
2/47. Imaging of an aneurysm of the sinus of valsalva with transesophageal echocardiography, contrast angiography and MRI.A sinus of valsalva aneurysm is an uncommon congenital defect, which requires appropriate diagnosis with either echocardiography, magnetic resonance imaging or contrast angiography. Treatment consists of aortic valve repair. We describe a young woman with an aneurysm of the non-coronary sinus of valsalva, an atrial septal defect and pulmonary insufficiency. The different imaging techniques and possibilities of surgical correction are described.- - - - - - - - - - ranking = 0.0032575659087768keywords = valve (Clic here for more details about this article) |
3/47. Isolated congenital absence of a single pulmonary valve cusp.Isolated absence of a single pulmonary valve is extremely unusual. We present a 16-year-old male with the absence of one cusp resulting in significant pulmonary regurgitation, right ventricular enlargement, and dilatation of the main pulmonary artery and its branches. Surgery consisted of creating a valve cusp from the posterior wall of the pulmonary artery at the base of the pulmonary trunk. Follow-up at 3.5 years revealed good results with only mild pulmonary stenosis and regurgitation.- - - - - - - - - - ranking = 5.0032575659088keywords = pulmonary valve, valve (Clic here for more details about this article) |
4/47. Isolated pulmonic valve endocarditis in healthy hearts: a case report and review of the literature.The case of a 53-year-old man with isolated pulmonic valve endocarditis in a structurally normal heart is presented. The patient had a history of chronic obstructive pulmonary disease and was admitted to hospital with an apparent exacerbation with pneumonia. blood cultures grew staphylococcus aureus, and an echocardiogram identified a large vegetation on the pulmonic valve in a structurally normal heart. He was unsuccessfully treated with antibiotics and eventually required pulmonic valve replacement. The literature from 1960 to 1999 identified only 36 reported cases of pulmonic valve endocarditis in structurally normal hearts. The present report underscores the importance of suspecting pulmonic valve endocarditis in patients with multiple pulmonary lesions, and discusses the predisposing factors, clinical features, diagnostic role of echocardiography and the potential benefits of early surgical treatment.- - - - - - - - - - ranking = 0.029318093178991keywords = valve (Clic here for more details about this article) |
5/47. Isolated pulmonic valve endocarditis caused by group B streprococcus (streptococcus agalactiae)--a case report and literature review.The pulmonic valve is the least commonly involved valve in infective endocarditis. Pulmonic valve endocarditis is usually associated with tricuspid valve endocarditis, and isolated pulmonic valve endocarditis is exceedingly rare. The predisposing factors for developing pulmonic valve endocarditis include a congenitally anomalous pulmonic valve, intravenous drug abuse, and the presence of indwelling intravenous or flow-directed pulmonary artery catheters. More cases of group B streptococcus endocarditis are being reported. The risk factors for group B streptococcus endocarditis include diabetes mellitus, cancer, alcoholism, malnutrition, immunocompromised status, intravenous drug abuse, postpartum and postabortion states, and underlying valvular disease. The vegetations of this type of endocarditis are usually large and have a higher tendency to result in embolism. The presentation of group B streptococcus endocarditis is usually acute and may result in rapid valve destruction if not treated promptly. A case of isolated pulmonic valve endocarditis caused by group B streptococcus, streptococcus agalactiae, is presented that was diagnosed with multiplane transesophageal echocardiography in a 40-year old, alcoholic, malnourished man, who was successfully treated with intravenous penicillin g. The literature on the isolated pulmonic valve endocarditis caused by group B streptococcus is reviewed.- - - - - - - - - - ranking = 0.045605922722875keywords = valve (Clic here for more details about this article) |
6/47. pulmonary valve injury: Swan-Ganz or surgery.pulmonary artery catheter (PAC) is a commonly used monitor in cardiac surgery. pulmonary valve injury from the balloon of the pulmonary artery catheter is exceedingly rare; its description by transesophageal echocardiography is nonexistent in the literature. A patient is reported who developed a flail anterior pulmonary leaflet several days after successful myectomy for hypertrophic cardiomyopathy. The temporal sequence of PAC use and four transesophageal echocardiography studies over 13 days, with the first three showing normal pulmonary valves, suggested pulmonary valve trauma, most likely from a Swan-Ganz catheter, as the etiology. Partial damage to the pulmonary valve from the original surgery may have predisposed the patient to further damage when the PAC was reintroduced in the intensive care unit.- - - - - - - - - - ranking = 3.0162878295439keywords = pulmonary valve, valve (Clic here for more details about this article) |
7/47. Triple valve replacement in a patient with severe carcinoid heart disease.We report on the case of a 34-year-old male patient suffering from end-stage carcinoid heart disease with severe tricuspid, pulmonary and mitral valve regurgitation. In addition, a persisting foramen ovale was present. The primary carcinoid tumor was never discovered. However, urine 5-hydroxy-indole-acetic-acid (5-HIAA) were consistently elevated after the first diagnosis of carcinoid disease and after eight years of medication with octreotide and Interferon alpha-2b our patient developed significant cardiac insufficiency mainly due to severe valvular dysfunction. Ultimately, mechanical tricuspid, mitral and pulmonary valve replacement was performed. Twelve hours following the operation the patient had to be returned to the operating room for persisting intrathoracic hemorrhage. He recovered uneventfully and was discharged from hospital on day 37. Twelve months following triple valve replacement the cardiac status recovered from preoperative NYHA-IV to NYHA-I.- - - - - - - - - - ranking = 1.0195453954527keywords = pulmonary valve, valve (Clic here for more details about this article) |
8/47. Correction of absent pulmonary valve syndrome using a pericardial valved conduit.Absent pulmonary valve syndrome in a 4-month-old infant was successfully corrected using a fresh autologous pericardial trileaflet valved conduit. He recovered from operation with only mild pulmonary regurgitation at 4 months postoperatively. This technique is an effective alternative for infants with congenital heart disease who need tissue valved conduits. It may be more suitable than the aortic homograft by reason of the shortage of small homografts and its lower costs.- - - - - - - - - - ranking = 5.0195453954527keywords = pulmonary valve, valve (Clic here for more details about this article) |
9/47. Beating-heart valvular surgery: a possible alternative for patients with severely compromised ventricular function.Cardioplegic arrest of the severely compromised ventricle may make weaning from cardiopulmonary bypass problematic. We report a novel approach to myocardial protection in a patient requiring multi-valve surgery who had an ejection fraction of 15%. Warm oxygenated blood was infused continuously both antegrade and retrograde during aortic valve replacement and mitral and tricuspid valve repair. Adequacy of perfusion was confirmed by the absence of electrocardiographic changes. Clinical improvement suggests that this strategy of myocardial protection warrants further investigation.- - - - - - - - - - ranking = 0.0097726977263304keywords = valve (Clic here for more details about this article) |
10/47. Functional pulmonary atresia in a newborn with normal intracardiac anatomy.Functional pulmonary atresia is a relatively rare clinical condition usually associated with Ebstein's malformation, tricuspid valve dysplasia, Uhl's anomaly, or transient myocardial ischemia with severe tricuspid regurgitation. The occurrence of functional pulmonary atresia associated with transient tricuspid regurgitation in a newborn with an anatomically normal heart is even more uncommon. We describe a case in which color Doppler flow mapping played an essential role in diagnosis and follow-up of this clinical condition in a newborn who had normal intracardiac anatomy.- - - - - - - - - - ranking = 0.020792664872494keywords = valve, pulmonary atresia, atresia (Clic here for more details about this article) |
