Left atrial myxoma causing near-total mitral valve obstruction.

ABSTRACT: Cardiac myxomas are the most common primary cardiac tumors in adults, with the left atrium being the most frequently affected. Echocardiography is the diagnostic modality of choice. The most effective treatment for cardiac myxomas is surgical excision.

Rheumatic mitral valve disease with left atrial myxoma: Unexpected encounter.

Project description:Rheumatic mitral stenosis associated with left atrial myxoma has been reported previously. We reported an admitted rare case of rheumatic mitral regurgitation with left atrial myxoma. The discrimination between left atrial myxoma and thrombi presents a diagnostic challenge in the presence of rheumatic mitral valve disease.

Two adherent blood cysts in subvalvular apparatus of the mitral valve causing severe left ventricular outflow tract obstruction.

Project description:Blood cysts in the heart are often incidentally found during post-mortem examinations in infants, and usually do not cause clinical symptoms. They almost always regress spontaneously, and only a few cases of embolization or valvular dysfunction have been reported previously. We report a 62-year-old man who presented with chest discomfort and dyspnea on exertion for several years, and was found to have a dynamic murmur in left ventricular outflow tract (LVOT) on physical examination. His echocardiogram demonstrated two large blood cysts attached to the subvalvular apparatus of mitral valve, causing significant LVOT obstruction and mild to moderate mitral regurgitation. The cysts were surgically excised and pathology confirmed simple blood cysts. <Learning objective: To the best of our knowledge, this is the first reported case of twin blood cysts with severe left ventricular outflow tract obstruction in an adult, since most of these cysts either regress spontaneously in childhood or remain asymptomatic in adults.>.

Left Atrial Dissection During Minimally Invasive Mitral Valve Surgery

Project description:Graphical abstract Highlights • LA dissection is a rare complication of cardiac surgery seen more often in MV repair.• It can present heterogeneously, from being benign to causing hemodynamic collapse.• Perioperative TEE is valuable in identifying LA dissection and aiding in management.• TEE can show the cause of instability, such as MV inflow or PV outflow obstruction.

Mitral Annular Kinetics, Left Atrial, and Left Ventricular Diastolic Function Post Mitral Valve Repair in Degenerative Mitral Regurgitation.

Project description:ObjectiveThe relationship of mitral annular (MA) kinetics to left ventricular (LV) and left atrial (LA) function before and after mitral valve (MV) repair has not been well studied. Here we sought to provide comprehensive analysis that relates to MA motions, and LA and LV diastolic function post MV repair.MethodsThree-dimensional analyses of mitral annular motion, LA function, and LV volumetric and diastolic strain rates were performed on 35 degenerative mitral regurgitation (MR) patients at baseline and 1-year post MV repair, and 51 normal controls, utilizing cardiac magnetic resonance imaging with tissue tagging.ResultsAll had normal LV ejection fraction (EF) at baseline. LV and LA EFs decreased 1-year post-surgery vs. controls. LV early diastolic myocardial strain rates decreased post-surgery along with decreases in normalized early diastolic filling rate, E/A ratio, and early diastolic MA relaxation rates. Post-surgical LA late active kick remained higher in MR patients vs. control. LV and LA EFs were significantly associated with peak MA centroid to apex shortening. Furthermore, during LV systolic phase, peak LV ejection and LA filling rates were significantly correlated with peak MA centroid to apex shortening rate, respectively. While during LV diastolic phase, both peak early diastolic MA centroid to apex relaxation rate and LA ejection rate were positively significantly associated with LV peak early diastolic filling rate.ConclusionMA motion is significantly associated with LA and LV function. Mitral annular motion, left atrial function, and LV diastolic strain rates are still impaired 1 year post MV repair. Long-term effects of these impairments should be prospectively evaluated.

Isolated left atrial cryoablation of atrial fibrillation in conventional mitral valve surgery.

Project description:BackgroundRecent trends of surgery for atrial fibrillation (AF) are towards more safe and effective energy sources, as well as to simplified sets of atrial lesions.MethodsOne hundred eighteen (mean age, 67.4 ± 9.2 years) selected patients with paroxysmal/persistent AF and mitral valve (MV) disease underwent cryoablation of AF combined with conventional (not via mini-thoracotomy) MV surgery; the lesion set was limited to only the left atrium. Multivariable analyses identified predictors of cardiac rhythm at hospital discharge and follow-up.ResultsThere were 7 (5.9%) hospital deaths; 33 (28%) patients were discharged on AF. Higher values of preoperative left atrial volume index (odds ratio [OR] = 1.07, 95% confidence interval [95%CI]: 1.01-1.13) and mixed etiology of MV disease (OR = 4.19, 95%CI: 1.23-14.2) were predictors of hospital discharge on AF. Seventy-four (66.7%) patients were on stable sinus rhythm at follow-up (median period, 6.6 years); the 1, 5, and 10-year nonparametric estimates of adjusted freedom from AF were 98.1%, 89.2% and 45.6%, respectively. Higher values of preoperative systolic pulmonary artery pressure (hazard ratio [HR] = HR = 1.04, 95%CI: 1.01-1.08) and AF at hospital discharge (HR = 4.14, 95%CI: 1.50-11.4) were predictors of AF at follow-up.ConclusionsDuring conventional MV surgery, a cryo-lesion set limited to only the left atrium may give good, immediate and long-term results. Left atrial dilation and mixed etiology of MV disease were predictors of hospital discharge on AF. Preoperative pulmonary hypertension and AF at discharge combined with an increased risk of AF at follow-up.
