Flanged Bentall Plus Cabrol Procedure for Interventricular Septal Dissection in Behçet's Disease.

Behçet's disease with interventricular septal dissection is extremely rare, and its surgical treatment is even more challenging. One such treatment with interventricular septal dissection repair was followed by the flanged Bentall and Cabrol techniques. The flange of the flanged composite graft was attached to the left ventricular outflow tract instead of the fragile annulus. The Cabrol procedure was performed to reduce anastomotic tension at the coronary button sites. Good short-term results were achieved.

Effect of early use of ivabradine on left ventricular remodeling after primary percutaneous coronary intervention in patients with acute ST-segment elevation myocardial infarction: A pilot test.

OBJECTIVE: To investigate the effect of early use of ivabradine on left ventricular remodeling after primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). METHODS: A total of 66 STEMI patients with sinus rhythm and the resting heart rate ≥80 bpm after successful emergency PCI were included. The patients in the test group were treated with ivabradine combined with metoprolol at 12 hr after PCI, while the control group was given only metoprolol orally. Their resting heart rate was controlled to <70 bpm at discharge and followed for 180 days. Heart rate and blood pressure were measured regularly. Echocardiogram was performed. N-terminal pro-B-type natriuretic peptide (NT-proBNP), high sensitivity troponin T, high sensitivity troponin I, and high sensitivity C-reactive protein were measured. The major adverse cardiovascular events during hospitalization and follow-up period were recorded. RESULTS: Compared with the control group, the heart rate of the test group decreased significantly (p < .05). Compared with the control group, the left ventricular end-diastolic volume and left ventricular end-systolic volume were significantly decreased while left ventricular ejection fraction was significantly increased in the test group at 90 days after operation. NT-proBNP of the test group was significantly lower than that of the control group at 7 days after operation (p < .05). CONCLUSION: For STEMI patients, early use of ivabradine combined with standard therapy such as ß-blocker after successful reperfusion can achieve effective heart rate control, with great safety and tolerance. But the effect of ivabradine on left ventricular remodeling is uncertain.

Three-dimensional transesophageal echocardiography measurement of mitral valve area in patients with rheumatic mitral stenosis: multiplanar reconstruction or 3D direct planimetry?

3D direct planimetry is increasingly used in clinical practice as a rapid way to measure the mitral valve area (MVA) in patients with rheumatic mitral stenosis (MS) who underwent three-dimensional transesophageal echocardiography (3D-TEE). However, data on its accuracy and reliability are scarce. This study aimed to compare the MVA measurements obtained by 3D direct planimetry to the conventional technique multiplanar reconstruction (MPR) in MS patients using 3D-TEE. We retrospectively included 49 patients with rheumatic MS undergoing clinically-indicated 3D-TEE in the study. We determined the 3D direct planimetry measurements of MVA from the left atria aspect (MVALA) and the left ventricle aspect (MVALV), and compared those with the MPR method (MVAMPR). We also assessed the major and minor diameters of the mitral valve orifice using MPR and 3D direct planimetry. We found an excellent agreement between the MVA measurements obtained by the MPR method and 3D direct planimetry (MVALA and MVALV) [intraclass correlation coefficients (ICC) = 0.951 and 0.950, respectively]. However, the MVAMPR measurements were significantly larger than the MVALA and MVALV (p < 0.001; mean difference: 0.12 ± 0.15 cm2 and 0.11 ± 0.16 cm2, respectively).The inter-observer and intra-observer variability ICC were 0.875 and 0.856 for MVAMPR, 0.982 and 0.984 for MVALA, and 0.988 and 0.986 for MVALV, respectively. The major diameter measured by MPR (1.90 ± 0.42 cm) was significantly larger than that obtained by 3D direct planimetry (1.72 ± 0.35 cm for the LA aspect, p < 0.001; 1.73 ± 0.36 cm for the LV aspect, p < 0.001). The minor diameter measured by MPR (0.96 ± 0.25 cm) did not differ from that derived by 3D direct planimetry (0.94 ± 0.25 cm for the LA aspect, p = 0.07; 0.95 ± 0.27 cm for the LV aspect, p = 0.32). 3D direct planimetry provides highly reproducible measurements of MVA and yields data in excellent agreement with those obtained by the MPR method. The discrepancy between the two techniques may be due to differences in major diameter measurements of the mitral valve orifice.
