[source] Mitral Valve Replacement with the Beating Heart Technique in a Patient with Previous Bypass Graft from Ascending to Descending Aorta due to Aortic CoarctationJOURNAL OF CARDIAC SURGERY, Issue 2 2008Ferit Cicekcioglu M.D. In this case, MVR was performed with on-pump beating heart technique without cross-clamping the aorta because of the diffuse adhesion around the ascending aorta, and tube graft presence between ascending and descending aortas. Methods: A 47-year-old female patient had aorto-aortic bypass graft from ascending aorta to descending aorta with median sternotomy and left thoracotomy in single stage because of aortic coarctation 2 years ago in our cardiac center. She was admitted to the hospital with palpitation and dyspnea on mild exertion. Transthoracic echocardiography revealed 4th degree mitral insufficiency. Results: MVR was carried out through remedian sternotomy with on-pump beating heart technique without cross-clamping the aorta. Conclusions: MVR with on-pump beating heart technique offers a safe approach when excessive dissection is required to place cross-clamp on the ascending aorta. [source] MR and CT assessment for ischemic cardiac diseaseJOURNAL OF MAGNETIC RESONANCE IMAGING, Issue 6 2004Richard D. White M.D. Abstract Magnetic resonance imaging and/or contrast-enhanced multidetector computed tomography may be used separately or, often more effectively, in an integrated fashion, to address important issues in patients with coronary artery disease causing ischemic cardiac disease (ICD). These issues include complications of myocardial infarction, such as ventricular dysfunction, myocardial wall rupture, aneurysm formation, intracavitary thrombus, mitral insufficiency, and pericarditis, as well as aspects of planning and monitoring therapy for ICD, such as revascularization and ventricular aneurysm repair.

[source] Aortic and mitral regurgitation: Quantification using moving slice velocity mappingJOURNAL OF MAGNETIC RESONANCE IMAGING, Issue 2 2001Sebastian Kozerke PhD Abstract Comprehensive assessment of the severity of valvular insufficiency includes quantification of regurgitant volumes. Previous methods lack reliable slice positioning with respect to the valve and are prone to velocity offsets due to through-plane motion of the valvular plane of the heart. Recently, the moving slice velocity mapping technique was proposed. In this study, the technique was applied for quantification of mitral and aortic regurgitation. Time-efficient navigator-based respiratory artifact suppression was achieved by implementing a prospective k-space reordering scheme in conjunction with slice position correction. Twelve patients with aortic insufficiency and three patients with mitral insufficiency were studied. Aortic regurgitant volumes were calculated from diastolic velocities mapped with a moving slice 5 mm distal to the aortic valve annulus. Mitral regurgitant flow was indirectly assessed by measuring mitral inflow at the level of the mitral annulus and net aortic outflow. Regurgitant fractions, derived from velocity data corrected for through-plane motion, were compared to data without correction for through-plane motion. In patients with mild and moderate aortic regurgitation, regurgitant fractions differed by 60% and 15%, on average, when comparing corrected and uncorrected data, respectively. Differences in severe aortic regurgitation were less (7%). Due to the large orifice area of the mitral valve, differences were still substantial in moderate-to-severe mitral regurgitation (19%). The moving slice velocity mapping technique was successfully applied in patients with aortic and mitral regurgitation. The importance of correction for valvular through-plane motion is demonstrated.

[source] Japan's First Robot-assisted Totally Endoscopic Mitral Valve Repair With a Novel Atrial RetractorARTIFICIAL ORGANS, Issue 10 2009Norihiko Ishikawa Abstract This case report presents the first robot-assisted totally endoscopic mitral valve plasty in Japan. A 54-year-old woman was found by echocardiography to have grade III mitral valve regurgitation because of prolapse of the posterior leaflet. Surgical repair was performed using the da Vinci Surgical System. For the totally endoscopic mitral valve repair, a right-sided approach was used through four ports. A transthoracic aortic cross-clamp and novel flexible port access retractor were inserted through a 5-mm skin incision. Quadrangular resection of the posterior leaflet was performed, and an annuloplasty band was placed into the atrium. Resection of the valve segment took 13 min, and band implementation, 45 min. The total pump time was 197 min and the aortic cross-clamp time, 117 min. Postoperative echocardiography confirmed the absence of mitral insufficiency. [source] | ||||||||||
