Project description:Anomalous left atrial chorda is associated with mitral regurgitation. A young woman presenting for mitral valve repair with the diagnosis of mid-segment (A2) of anterior mitral leaflet prolapse causing severe mitral regurgitation. Transesophageal echocardiography examination in pre-bypass period showed an anomalous chorda attaching A2 to the left atrial roof, tethering the anterior mitral leaflet toward the atrial wall. Surgical findings confirmed the abnormally attached chordae and an absence of normal chorda of A2 segment. The anomalous chorda was resected and neo-chordae placed between the A2 segment and papillary muscles and annulus strengthened with an annuloplasty ring.

Giant Left and Right Atrium in Rheumatic Mitral Stenosis and Tricuspid Regurgitation.

Project description:Dilation of atria occurs in patients with valvular heart disease, especially in rheumatic mitral regurgitation, mitral stenosis, or tricuspid valve abnormalities. We report a case of giant left and right atrium in the context of rheumatic mitral stenosis and severe tricuspid regurgitation in a 68-year-old woman.

Impact of left atrium plication on chronic heart failure with atrial functional mitral regurgitation.

Project description:PurposeWe hypothesized that a giant left atrium may oppress the posterior left ventricle and aggravate diastolic dysfunction and heart failure. We evaluated the effect of left atrial plication (LAP) on atrial functional mitral regurgitation.MethodsWe retrospectively reviewed patients who underwent LAP for atrial functional mitral regurgitation at our institution between January 2017 and December 2021. Early outcomes, follow-up echocardiography data, and heart failure indicators were compared.ResultsEighteen patients were divided into two groups: LAP + (n = 9) or LAP- (n = 9). There were no significant differences in patient characteristics and preoperative echocardiographic parameters, except for the preoperative New York Heart Association classification. Operative (505.7 [standard deviation: 100.0] minutes vs. 382.9 [standard deviation: 58.1] minutes, P = .0055) and cardiopulmonary bypass times (335.6 [standard deviation: 50.4] minutes vs. 246.9 [standard deviation: 62.7] minutes, P = .0044) were significantly longer in the LAP + group. No in-hospital mortalities were observed in both groups. The postoperative left atrial volume was significantly reduced in the LAP + group, and mitral regurgitation was controlled at less than mild levels in both groups. At follow-up, the left ventricular end-diastolic volume was reduced significantly in the LAP + group. Brain natriuretic peptide, cardiothoracic ratio, and the New York Heart Association classification were improved in the LAP + group.ConclusionsAdditional left atrial plication contributes to the control of atrial functional mitral regurgitation and heart failure at a later stage. A careful long-term follow-up is needed as re-expansion of the left atrium is possible.Supplementary informationThe online version contains supplementary material available at 10.1007/s12055-023-01569-6.

A rare case of left dominant pulmonary edema in acute mitral regurgitation.

Project description:Unilateral pulmonary edema (UPE) due to cardiac causes is an unusual clinical finding and typically emerges on the right side. UPE poses a diagnostic challenge due to difficulty distinguishing infiltrative pneumonia from cardiogenic edema on chest imaging. Consequently, corrective clinical management is significantly delayed in UPE compared to bilateral cardiogenic pulmonary edema. We present a very rare case of left-sided cardiogenic pulmonary edema due to acute severe MR wherein a prompt cardiac evaluation for UPE led to successful corrective surgery and favorable outcome.

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa with fistulous communication to the left atrium causing congestive heart failure.

Project description:Pseudoaneurysms of the mitral-aortic intervalvular fibrosa can rupture and form fistulous communications between the left ventricle and left atrium. Pulmonary venous systolic flow reversal in such cases reflects elevated left atrial pressure due to shunting. This finding, particularly in the setting of endocarditis, is not specific for severe mitral regurgitation.
