“…In papers focusing on atrial electroanatomic characteristics, the voltage level <0.5 mV is often used, as specific for fibrosis assessment during SR or atrial stimulation. 16,17 Fiala et al, 23 We did not find a significant relationship between LAPA and echocardiographic parameters describing LA geometry and function in a subgroup of patients with AF. During AF, LA's function as a reservoir and conduit is severely impaired, and systolic function does not exist.…”

“…All transthoracic and transoesophageal echocardiograms were performed in the first 30 days after the acute ischemic stroke by a senior certified echocardiography cardiologist, according to the recommendations of the European Association of Cardiovascular Imaging (EACVI) in vigor at that time. 9,[18][19][20][21][22][23][24][25][26][27][28][29][30] The exams were performed with the commercially available ultrasonographic systems (Vivid 7, GE Medical Systems). We collected the available echocardiographic data from the echocardiogram report written at that time.…”

A lower left atrial appendage peak emptying velocity in the acute phase of cryptogenic stroke predicts atrial fibrillation occurrence during follow‐up

Background Silent atrial fibrillation is a frequent etiology of cryptogenic stroke. Spontaneous conversion of atrial fibrillation to sinus rhythm results in atrial stunning. Objective To evaluate if the presence of a lower left atrial appendage peak emptying velocity (LAAV) after a cryptogenic stroke is associated with the occurrence of atrial fibrillation (AF). Methods We retrospectively selected consecutive patients with an acute ischemic stroke that had a transoesophageal echocardiogram (TEE) performed in the first 30 days of the acute event. Documented AF or potential cardioembolic sources in the TEE were considered exclusion criteria. We assessed the LAAV. During follow‐up, we evaluated the occurrence of new‐onset AF and the combined endpoint of death or new ischemic stroke. Results We studied 73 consecutive patients, during a mean follow‐up period of 54.9 ± 19.3 months. Seven developed AF, and 13 had the combined endpoint. LAAV was independently associated with AF occurrence (HR: 0.93, 95% CI: 0.88–0.99; P = .016). Patients with a LAAV ≤ 46.5 cm/s (AUC: 0.766, 95% CI: 0.579–0.954; P = .021) had a lower survival rate free from AF occurrence (Log‐rank, P < .001) and free from the combined endpoint of death or ischemic stroke (Log‐rank, P = .010). Conclusion A lower LAAV was associated with AF occurrence and the combined endpoint of death or ischemic stroke after an initial episode of cryptogenic stroke. Patients with this finding could eventually benefit from long‐term cardiac rhythm monitoring.

“…[13][14][15] Nowadays, the real time 3D-TEE provides an excellent quality images with a higher resolution when it crosses the MV for that may be suitable for planimetric measurement of MVA. 16,17 Therefore, this study uses the average of 4 different planimetric measurement methods of the MVA in 3D images obtained from TEE (m3D-TEE), as the gold standard for all comparisons. The correlation of the sizes measured by 3D techniques in TTE and m3D-TEE has not been tested in patients with smaller area size of the MV.…”

Level of agreement in three‐dimensional planimetric measurement of mitral valve area between transthoracic and transesophageal echocardiography

et al. 2019

Background Echocardiographic measurement of mitral valve area (MVA) is critical prior to percutaneous transmitral commissurotomy (PTMC). This study aimed to compare the agreement between transthoracic (TTE) and transesophageal echocardiography (TEE) in three‐dimensional (3D) planimetric measurement of the MVA among patients with severe mitral stenosis. Methods MVA was measured with planimetry in 105 patients before undergoing PTMC. 3D reconstruction was applied to both TTE and TEE examinations. The MVA values from four different methods of 3D reconstruction were compared to the average values of 3D methods in TEE as the gold standard measurement method for the MVA in this study. The agreement levels between the two examinations were evaluated and analyzed for various reconstruction methods. Results The mean age was 49 ± 12 years for 28 men and 77 women who were enrolled. The image quality was graded as “excellent” in 57% of 3D images obtained by TTE, while it was graded as “excellent” in 81% of 3D images obtained by TEE. The ventricular zooming method in TTE with a bias of −0.006 ± 0.065 cm2 (P < 0.0001) had the highest agreement with the 3D‐MVA in TEE. While 2D‐TTE and 3D‐TEE measurements of the MVA (R = 0.91; P < 0.0001) were significantly correlated, 2D‐TTE overestimated the MVA by 0.19 cm2. Conclusion Although the quality of 3D images was significantly better in TEE than those in TTE, a good agreement existed between the measured 3D‐TTE and 3D‐TEE studies. We also demonstrated that 2D‐TTE overestimated the MVA compare to 3D‐TEE.
