1/30. Placement of an intracoronary stent via translumbar puncture.Translumbar puncture for access to the central arterial tree has been used for aortography and for selective coronary angiography in selected patients where conventional peripheral access is not possible. A single case report of coronary angioplasty through this access technique is available in the literature. We report a case of coronary stent placement using the translumbar approach to access the coronary arteries.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
2/30. Coronary ostial patch angioplasty in children.Patch angioplasty for coronary artery ostial stenosis was first reported in adults in 1952 and only sparsely used until 1983 when Hitchcock reviewed the technique in adults. We present two cases that highlight our use of this technique in inflammatory diseases of the aorta in children. Patch angioplasty restores physiologic perfusion of the coronary artery tree, preserves conduit material for further procedures later in life, and allows subsequent percutaneous transluminal coronary angioplasty of stenosis. For these reasons we believe that patch angioplasty holds undoubted advantage over the available alternatives.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
3/30. Vineberg revisited. Long-term survival more than two decades after direct surgical myocardial revascularization.A 65-year old patient was referred to our institution for a diagnostic catheterization. 23 years before, a direct surgical myocardial procedure using the Vineberg technique was performed. Currently, the angiogram shows patent left and right internal mammary arteries implanted directly into the myocardium and connecting with the native circulation through collaterals. As the native coronary artery tree shows very severe three vessel disease, it is hypothesized that the major contribution of myocardial perfusion comes from the implanted vessels. This is the first case to show a long-term success of the Vineberg operation, with persistence of myocardial perfusion through newly formed vasculature.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
4/30. Fatal air embolism during thoracotomy for gunshot injury to the lung. Report of a case.Fatal coronary air embolism occurred during thoracotomy in a patient with a gunshot wound involving the hilum of the right lung. embolism was observed during a second period of failure of heart action. Evidently, air entered the pulmonary veins from the bronchus, which was receiving positive-pressure ventilation. The literature contains reports of only 3 similar cases, but we suspect that air embolism may be responsible for death and morbidity in additional cases in which accidental or iatrogenic lung trauma has produced a pathway between the bronchial tree and the pulmonary veins.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
5/30. "Skirt" technique for coronary artery bifurcation stenting.Stent implantation in the treatment of coronary artery bifurcation lesions frequently impairs blood flow and gives the coronary tree a new, metallic configuration. The new technique we describe uses a single short stent in a "skirt" shape which produces no "jailing" effects and can be used in the treatment of true coronary Y-shaped bifurcation lesions.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
6/30. Ectopic origin of the left anterior descending coronary artery from the right coronary sinus. Report of a case simulating anterior descending obstruction.A patient with anomalous aortic origin of the left anterior descending coronary artery was studied. The clinical picture and the preliminary angiographic findings simulated obstruction of the left anterior descending coronary artery near its origin. Careful catheter exploration of the right coronary sinus led to the correct diagnosis, emphasizing the importance of complete visualization of all branches of the coronary tree, including distal radicles of a supposedly occluded vessel.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
7/30. Total occlusion of left main coronary artery in a patient with chronic, stable angina.We report a case of total occlusion of the left main coronary artery (LMCA) in a patient with chronic, stable angina. Total occlusion of the LMCA is rare and survival depends on the existence of collateral circulation. In LMCA disease, there is usually also disease in other parts of the coronary arterial tree.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
8/30. A uncommon cause of angina during upper limb exercise.subclavian artery stenosis or occlusion may be a cause of myocardial ischemia in patients treated using an internal mammary artery graft. Subclavian stenosis may cause myocardial ischemia during arm exercise by a coronary-subclavian steal phenomenon, with flow inversion in the graft from the coronary tree to the left subclavian artery. We here describe a case of a patient developing left subclavian occlusion after coronary artery bypass grafting with the left internal mammary artery. The lesion was successfully treated with a carotid-subclavian bypass. The article underscores the importance of an early diagnosis (possibly before bypass surgery) and discusses possible treatments. Percutaneous interventions with stent implantation appear the treatment of choice, but surgery has an important role in case of total occlusion.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
9/30. Off pump coronary artery bypass grafting in a patient with tracheopathia osteoplastica.Tracheopathia osteoplastica is a rare disease of the tracheobronchial tree, which is often misdiagnosed and recognised only at post-mortem. We report the case of a 66-year-old man with this condition, mistakenly thought to be suffering from chronic bronchiectasis. He underwent successful coronary artery bypass grafting for unstable angina using an off-pump technique. A case report and brief literature review is presented.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
10/30. The use of multiple "buddies" during transradial angioplasty in a complex calcified coronary tree.We report our experience in transradial coronary angioplasty on a tortuous, calcified coronary tree in a patient who had been turned down for surgical revascularization. In view of the complexity of the coronary anatomy, successful completion of the procedure required plaque modification with the use of rotational atherectomy in the left anterior descending coronary artery, and the use of an inflated buddy balloon in the circumflex artery. The latter represents a novel, simple, and inexpensive technique, which may allow successful advancing of coronary stents in calcified and tortuous coronary arteries.- - - - - - - - - - ranking = 5keywords = tree (Clic here for more details about this article) |
