1/184. Development of rib notching after a cava-pulmonary anastomosis.A patient with tetralogy of fallot and mitral regurgitation developed unilateral rib notching on the right side secondary to a palliative cava-pulmonary anastomosis. After the operation, decreased perfusion of the right upper and middle lobes stimulated the development of collateral vessels from the systemic circulation to the right pulmonary artery. To our knowledge, this is the first time that this has been described.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
2/184. 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 = 290.78156928642keywords = coronary (Clic here for more details about this article) |
3/184. Transient severe mitral regurgitation complicating myocardial stunning due to coronary vasospasm.As in papillary muscle dysfunction complicating mitral prolapse, dyskinesis of the left ventricular wall underlying the papillary muscles has been shown to cause mitral regurgitation following myocardial infarction. myocardial stunning has been experimentally evidenced to cause mitral regurgitation due to a wall motion abnormality, but it has not yet been clinically defined. We report a clinical case of transient severe mitral regurgitation complicating myocardial stunning caused by coronary vasospasm. Transient wall motion abnormality beneath the anterolateral papillary muscle was considered to be responsible for the mitral regurgitation.- - - - - - - - - - ranking = 290.78156928642keywords = coronary (Clic here for more details about this article) |
4/184. An unusual iatrogenic cause of right coronary air embolism.A 62-year-old woman undergoing redo mitral valve replacement was noted to have persistent intracardiac air following standard deairing procedures. Transesophageal echocardiography (TEE) identified air bubbles entering the left atrium from the right superior pulmonary vein. Exploration of the pleural cavity revealed a fistula between the pulmonary parenchyma and the right superior pulmonary vein caused by the atriotomy closure suture transfixing the edge of the lung, which was repaired with immediate disappearance of the air emboli. This demonstrates that transesophageal echocardiography is an invaluable aid to ensuring complete deairing after open heart procedures.- - - - - - - - - - ranking = 232.62525542913keywords = coronary (Clic here for more details about this article) |
5/184. Transcatheter closure of a patent foramen ovale following mitral valve replacement.We report the successful closure of a postoperative patent foramen ovale in a patient who underwent coronary artery bypass grafting and mitral valve replacement for severe mitral insufficiency. The postoperative course was complicated by severe hypoxemia due to a large patent foramen ovale. The patient underwent transcatheter closure with the Das Angel Wings transcatheter occluder (Microvena Corporation, White Bear Lake, MN) with immediate improvement.- - - - - - - - - - ranking = 58.156313857283keywords = coronary (Clic here for more details about this article) |
6/184. Catheter entrapment by atrial suture during minimally invasive port-access cardiac surgery.PURPOSE: The port-access approach allows surgeons to perform heart operations through small intercostal openings, or "ports". This technique requires new skills for anesthesiologists. A pulmonary artery venting (PAV) catheter and, in some cases, a coronary sinus catheter (for administration of retrograde cardioplegia) are positioned with the aid of fluoroscopy and transesophageal echography (TEE). Both catheters have a wider diameter than the more commonly used conventional PA catheter and present distinctive features. We report a case in which a pulmonary artery venting catheter was entrapped by a suture during a port-access procedure. CLINICAL FEATURES: A 35-yr-old man with severe mitral valve insufficiency was scheduled for valve repair. After a successful bypass procedure, resistance was felt while attempting to withdraw the PAV catheter. On fluoroscopy, fixation of the catheter at the heart level was established and perforation by suture was confirmed after injection of a contrast agent. Because of the risk of cardiac wall rupture and tamponade, the thorax was reopened. After release of some atrial sutures, the catheter could be withdrawn easily. Transfixion by a suture was confirmed by visual examination. CONCLUSION: The more frequent use of a PAV catheter in minimally invasive cardiac surgery with the port-access technique should remind the anesthesiologist of the higher risk of entrapment by surgical sutures. Surgeons should be aware of the risk of accidentally transfixing this catheter during closure of the atriotomy via the port.- - - - - - - - - - ranking = 58.156313857283keywords = coronary (Clic here for more details about this article) |
7/184. Use of a retractor designed to harvest an internal thoracic artery graft during cardiac surgery for patients with a unilateral lung.Adequate exposure of the heart is required for safe cardiac surgery. We performed open heart surgery for 2 patients with a unilateral lung. In one patient, coronary artery bypass grafting was performed 13 years after left pneumonectomy for lung cancer. Mitral valve replacement was performed in the other patient whose left lung was entirely collapsed due to tuberculosis. The heart was markedly deviated to the left in both patients. A retractor designed to harvest the internal thoracic artery was very useful to obtain a good operative view of the heart. The operations were uncomplicated, and postoperative recovery was uneventful in both patients.- - - - - - - - - - ranking = 58.156313857283keywords = coronary (Clic here for more details about this article) |
8/184. An adult case of bland white garland syndrome with huge right coronary aneurysm.We report the case of a 62-year-old male patient with left main coronary artery originating from the pulmonary trunk, severe mitral insufficiency, and huge right coronary artery aneurysm. He is the oldest such patient among those reported in the literature, surviving to the sixth decade without any anginal symptoms. He is also the first such case with such a huge and calcified right coronary artery aneurysm and a prominent collateral from the noncoronary circulation.- - - - - - - - - - ranking = 466.25051085827keywords = coronary, circulation (Clic here for more details about this article) |
9/184. Systolic anterior movement of mitral valve during acute apical myocardial infarction: An unusual mechanism of acute mitral regurgitation.We describe a singular case of a 75-year-old woman affected by an anterior acute myocardial infarction in the subset of a very recent orthopaedic surgery. She had had severe mitral regurgitation on coronary angiography. A thorough cardiac echocardiographic examination revealed the particular mechanism of mitral incompetence, consisting of a dynamic anterior mitral leaflet displacement caused by a sustained compensatory left ventricle hypercontractility and favored by postsurgical moderate anemia and mild hypertensive hypertrophy. The use of beta-blockers and the avoidance of pure vasodilators permitted complete reversal of such mechanisms during the clinical course.- - - - - - - - - - ranking = 58.156313857283keywords = coronary (Clic here for more details about this article) |
