1/33. myocardial infarction caused by compression of anomalous circumflex coronary artery after mitral valve replacement.We report a case of myocardial infarction after mitral valve replacement occurring in a patient with the left cyrcumflex coronary artery arising from the right one. The patient underwent mitral valve replacement with a size 27 Carbomedics prosthesis and a tricuspidal annuloplasty was performed according to the De Vega technique. Patient died on the 20th postoperative day.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/33. Difference in structural change in the Carpentier-Edwards pericardial valves implanted in the mitral and tricuspid positions.We report a 29-year-old patient with prosthetic valve dysfunction with severe calcific stenosis in the mitral position but no structural change in the tricuspid position after mitral valve replacement and tricuspid valve supra-annular implantation with same bioprostheses at the seven years before. The difference in structural change between the mitral position and the tricuspid position might be due mainly to the effect of mechanical stress on the cusps, rather than to any difference in serum calcium levels. However, some hormonal effect other than that of the parathyroid hormone on the systemic and pulmonary circulation might be related to the early progression in cusp calcification in the systemic circulation.- - - - - - - - - - ranking = 0.079280142393409keywords = circulation (Clic here for more details about this article) |
3/33. Minimally invasive parasternal approach to tricuspid valve avoids repeat sternotomy.We report the case of a 68-year-old patient with severe tricuspid regurgitation who had previously undergone aortic valve replacement and right coronary artery bypass. We performed tricuspid valvuloplasty via the right parasternal route in order to reduce surgical trauma by avoiding resternotomy, trauma to the venous graft, and bleeding due to dissection of old adhesions. The patient's postoperative course was uneventful, and he was discharged home on the 7th postoperative day.- - - - - - - - - - ranking = 0.2keywords = coronary (Clic here for more details about this article) |
4/33. Left main coronary artery compression by dilated main pulmonary artery in endocardial cushion defect.A 56-year-old man was evaluated for exertional dyspnoea. Chest X-ray showed mild cardiomegaly and a dilated main pulmonary artery. On echocardiogram he was found to have ostium primum atrial septal defect with moderate tricuspid insufficiency. cardiac catheterization revealed an oximetry step-up of 14% at low right atrium with angiogram demonstrating a cleft in the mitral valve, an elongated left ventricular outflow tract and ventricular septal defect closed by a septal aneurysm. Coronary angiogram revealed ostial compression of the left main coronary artery with the rest of the coronary artery anatomy being normal.- - - - - - - - - - ranking = 1.2keywords = coronary (Clic here for more details about this article) |
5/33. Surgical repair of a common atrium in an adult.We report a rare successful surgical repair of a common atrium (CA) with mild tricuspid valve (TV) regurgitation due to valvular annulus enlargement in a 39-year-old man, who had a complete atrial septum defect (ASD) without the characteristic of an endocardial cushion defect. The left-to-right shunt ratio was 85 percent and the Qp/Qs was 6.7 due to the CA. Left ventriculogram revealed no evidence of typical goose-neck deformity and no mitral valve regurgitation. The operation consisted of making a new atrial septum with an autologous pericardial patch and tricuspid annuloplasty (DeVega) using extracorporeal circulation. There was no evidence of a cleft on the anterior leaflet of the mitral valve or the septal leaflet of the TV. The postoperative echocardiogram showed no residual shunt flow through a new atrial septum and no TV regurgitation, and atrioventricular (AV) dissociation did not occur. We consider this procedure to be widely applicable in consideration of the favorable results obtained after surgical treatment.- - - - - - - - - - ranking = 0.039640071196704keywords = circulation (Clic here for more details about this article) |
6/33. Neonatal transcatheter occlusion of a large coronary artery fistula with Amplatzer duct occluder.A large fistula from the right coronary artery to the right atrium was diagnosed in a fetus at 22 weeks of gestation. Following delivery, the baby developed cardiac failure. The fistula was occluded at 3 weeks of age by transcatheter implantation of an Amplatzer duct occluder. Large coronary fistulas can be closed safely with a device even at this early age. Vigilance for ischemic events is required following implantation because of the rare possibility of thrombus extension proximally into the native coronary artery or spasm of the coronary artery.- - - - - - - - - - ranking = 1.6keywords = coronary (Clic here for more details about this article) |
7/33. Isolated tricuspid stenosis and heart failure: a focus on carcinoid heart disease.A rare clinical occurrence, heart failure in the setting of tricuspid stenosis should immediately trigger a search for underlying systemic carcinoid disease. carcinoid tumor cells can secrete a variety of vasoactive substances that result in skin erythema, excretory diarrhea, bronchospasm, and hemodynamic instability, but these manifestations are noted only in a few patients. Right heart valvular disease is common since the vasoactive noxious substances pass through the right heart unaffected and undergo metabolism in the pulmonary circulation, thereby decreasing involvement of the left-sided valves. Localization of the carcinoid tumor followed by surgically directed valvular treatment is mandatory for relief of symptoms. In nonoperative candidates, cytotoxic chemotherapy or long-term symptomatic drug treatment with somatostatin is indicated.- - - - - - - - - - ranking = 0.039640071196704keywords = circulation (Clic here for more details about this article) |
8/33. Live three-dimensional transthoracic echocardiographic assessment of anomalous origin of left coronary artery from the pulmonary artery.We describe live three-dimensional transthoracic echocardiographic (3DTTE) findings in a 52-year-old female who had previously undergone an aortopulmonary tunnel operation for anomalous origin of the left coronary artery (ACA) from the pulmonary artery. Three-dimensional transthoracic echocardiography clearly delineated the origin of the ACA from the posterolateral aspect of the main pulmonary artery just above the pulmonary valve, the surgically created tunnel, as well as a small defect in the tunnel near the aortic end communicating with the pulmonary artery.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
9/33. Electrocardiographic-gated multislice computed tomography for visualization of cardiac morphology in congenitally corrected transposition of the great arteries.A case of congenitally corrected transposition of the great arteries in a 64-old-woman is presented. diagnosis was missed by invasive angiocardiography. Electrocardiographic-gated multislice computed tomography not only demonstrated switching of the aortic root and pulmonary trunk but clearly identified fine morphologic details of the cardiac chambers, including the atypical coronary artery pattern.- - - - - - - - - - ranking = 0.2keywords = coronary (Clic here for more details about this article) |
10/33. tricuspid valve repair for biopsy-induced regurgitation in a heart transplant recipient.Tricuspid regurgitation (TR) is a frequent complication after heart transplantation. The etiology of TR is multifactorial, but biopsy-induced flail leaflet is one of the most important mechanisms. A 61-year-old woman underwent heart transplant, but experienced several rejection episodes which required multiple surveillance endomyocardial biopsies. At three months after transplant, she required tricuspid valve repair due to symptomatic severe TR. The anterior leaflet was flail, with rupture of primary and secondary chordae. Valve repair was performed with a triple leaflet edge-to-edge technique. The procedure consisted of suture fixation of the prolapsed anterior leaflet joining to the septal and posterior leaflets, and placement of a 30-mm annuloplasty ring. The patient was uneventfully discharged home on day 7 with trivial TR. At a four-years post-transplant evaluation, she was in NYHA functional class I, with preserved ventricular function and trivial TR. She has been followed closely because of post-transplant coronary artery disease.- - - - - - - - - - ranking = 0.2keywords = coronary (Clic here for more details about this article) |
