Successful surgical repair of a giant calcified left ventricular aneurysm: a report of a case.
(49/105)
A 68-year-old man presented at the outpatient clinic with epigastric discomfort. He had suffered a myocardial infarction 10 years previously. Chest radiography and computed tomography showed a giant calcified aneurysm in the left ventricle. Electrocardiography indicated atrial fibrillation. Echocardiography showed moderate mitral regurgitation and enlarged left atrium. End-diastolic volume and ejection fraction were 164 ml and 31%, respectively. Coronary angiography revealed total occlusion of the left anterior descending artery and diffuse stenosis of the right coronary artery. Aneurysmectomy, mitral annuloplasty, maze procedure, and coronary artery bypass were performed. The patient was discharged 16 days postoperatively in a satisfactory condition without complications.

Anterior mitral leaflet perforation identified by real time three-dimensional transesophageal echocardiography.
(51/105)
With its unique en face view, real time three-dimensional transesophageal echocardiography has been reported to be more precise than conventional two-dimensional studies in evaluating mitral regurgitation etiology, and can locate diseased segments correctly. We present a case with severe mitral regurgitation due to anterior mitral leaflet perforation. Intraoperative real time three-dimensional transesophageal echocardiography demonstrated its value in diagnosis and surgical planning for this perforation, which had not been identified preoperatively. This technique should be applied more widely for dedicated mitral valve assessment in clinical practice. (+info)

Left circumflex coronary artery occlusion after mitral valve annuloplasty: "a stitch in time".
(56/105)
The left circumflex coronary artery is susceptible to injury during mitral valve surgery because of its proximity to the mitral valve annulus. We report the case of a 73-year-old woman who had undergone mitral valve repair and experienced a perioperative myocardial infarction due to occlusion of the left circumflex coronary artery. After percutaneous coronary intervention, a fistulous communication had developed between the stented portion of the left circumflex coronary artery and the left atrium, which, to our knowledge, is the first report of such a complication. The patient underwent successful mitral valve replacement. Although injuries to the left circumflex coronary artery are rare during mitral valve surgery, we believe that increasing awareness of the risk will help to prevent potentially fatal complications. We also recommend that surgeons gather as much detail as possible about the patient's anatomy before operation, use careful and meticulous surgical techniques, and use transesophageal echocardiography to look for wall-motion abnormalities before closing the incision.
