We report here on a case of double-orifice mitral valve with mitral regurgitation in a 75-year-old female who had complaints of mild dyspnea. Transthoracic and transesophageal echocardiography showed two orifices that were supplied by their own chordae from a different papillary muscle. Color Doppler echocardiography revealed moderate to severe mitral regurgitation due to the flail posterior leaflet of the anterolateral orifice. Except for the persistent left superior vena cava, no other congenital anomaly was demonstrated. The patient became asymptomatic with the administration of angiotensin-converting enzyme inhibitor and diuretics, and she has been scheduled for long term follow-up.

Cardiogenic unilateral pulmonary edema (UPE) is a rare clinical entity that is often misdiagnosed at first. Most cases of cardiogenic UPE occur in the right upper lobe and are caused by severe mitral regurgitation (MR). We present an unusual case of right-sided UPE in a patient with cardiogenic shock due to acute myocardial infarction (AMI) without severe MR. The patient was successfully treated by percutaneous coronary intervention and medical therapy for heart failure. Follow-up chest Radiography showed complete resolution of the UPE. This case reminds us that AMI can present as UPE even in patients without severe MR or any preexisting pulmonary disease affecting the vasculature or parenchyma of the lung.

We compared clinical (30+/-24 months) and echocardiographic follow-up (22 +/- 20 months) data of 184 consecutive patients with myxomatous degenerative mitral regurgitation (Group A) and 85 consecutive patients with rheumatic mitral regurgitation (Group B) after repair. Selection criteria for rheumatic etiology was predominant mitral regurgitation with valve area >or= 2.0 cm2 and with no significant calcification in valvular apparatus. Repair was successful in 93% of group A and in 92% of group B (p>0.05). There was no difference of operative mortality (1% vs 0%) and of the incidence of the second-pump valve replacement (4% vs 5%). The 4-yr survival, 4-yr event-free survival, and 4-yr mitral regurgitation-free survival rates in group A were 96 +/- 2%, 89 +/- 4%, and 76 +/- 5%, respectively, which were not different from those in group B (97 +/-2 %, 93 +/- 4%, and 68 +/-7 %, p >0.05). Independent determinants of development of at least moderate regurgitation in group A were no use of ring annuloplasty (hazards ratio 6.6, 95% CI 2.0 to 21.5) and new chordae formation (hazards ratio 3.5, 95% CI 1.4 to 8.7). In group B, no use of ring annuloplasty (hazards ratio 15.3, 95% CI 3.5 to 66.7) also was independent predictor. Valve repair is highly feasible in selected patients with rheumatic mitral regurgitation, and clinical course is not significantly different from that of patients with degenerative mitral regurgitation.
