Mike- Cardiac shock wave therapy improves myocardial perfusion and preserves left ventricular mechanics in patients with refractory angina: A study with speckle tracking echocardiography(2018) DUQUE, Anderson S.; CECCON, Conrado L.; JR, Wilson Mathias; MAJESKY, Joana Diniz; GOWDAK, Luis H.; SBANO, Joao C. N.; CESAR, Luis Antonio Machado; ABDUCH, Maria Cristina; LIMA, Marcio S. M.; DOURADO, Paulo M. M.; V, Cecilia B. B. Cruz; TSUTSUI, Jeane M.BackgroundCardiac shockwave therapy (CSWT) is a new potential option for the treatment of patients with chronic coronary disease and refractory angina (RA). We aimed to study the effects of CSWT on left ventricular myocardial perfusion and mechanics in patients with RA. MethodWe prospectively studied 19 patients who underwent CSWT. Left ventricular mechanics were evaluated by speckle tracking echocardiography (STE), and myocardial perfusion by single-photon emission computed tomography, using stress/rest-Technetium-99m Sestamibi, for determination of summed stress score (SSS). Canadian Cardiac Society (CCS), New York Heart Association (NYHA), and quality of life by Seattle Angina Questionnaire (SAQ) were assessed at baseline and 6months after therapy. ResultsCSWT therapy was applied without major side effects. At baseline, 18 patients (94.7%) had CCS class III or IV, and after CSWT there was reduction to 3 (15.8%), P=.0001, associated with improvement in SAQ (38.5%; P<.001). Thirteen (68.4%) had class NYHA III or IV before treatment, with significant reduction to 7 (36.8%); P=.014. No change was observed in the global SSS from baseline to 6-month follow-up (15.338.60 vs 16.60 +/- 8.06; P=.157). However, there was a significant reduction in the average SSS of the treated ischemic segments (2.1 +/- 0.87 pre vs 1.6 +/- 1.19 post CSWT; P=.024). Global longitudinal strain by STE remained unaltered (-13.03 +/- 8.96 pre vs -15.88 +/- 3.43 6-month post CSWT; P=.256). ConclusionCSWT is a safe procedure for the treatment of patients with RA that results in better quality of life, improvement in myocardial perfusion of the treated segments with preservation of left ventricular mechanics.

- Relation of mitral valve morphology to surgical repair results in patients with mitral valve prolapse: A three-dimensional transesophageal echocardiography study(2018) PARDI, Mirian M.; POMERANTZEFF, Pablo M. A.; SAMPAIO, Roney Orismar; ABDUCH, Maria C.; BRANDAO, Carlos M. A.; MATHIAS JR., Wilson; GRINBERG, Max; TARASOUTCHI, Flavio; VIEIRA, Marcelo L. C.BackgroundThe identification of predictors of mitral valve (MV) repair results is important for quality improvement in cardiac surgery. The aim of this study was to evaluate the relationship between MV morphological quantification by three-dimensional (3D) transesophageal echocardiography and mitral repair results. MethodsFifty-four patients with MV prolapse who were submitted to surgical repair were divided into 2 groups according to their postoperative mitral regurgitation (MR) degree (group 1, grade 0-I MR; group 2, grade II MR). Morphological parameters related to the mitral ring, dimension of leaflets and prolapse, coaptation line, distance from papillary muscles to the leaflet border and valve angles were analyzed by 3D MV quantification. Cardiac remodeling and MR quantitative parameters were also evaluated. ResultsThere was no correlation between 3D MV quantification and surgical results; a multivariate analysis did not show an association between morphological parameters and surgical outcome. The distance from the posteromedial papillary muscle to the leaflet border was higher (P=.038) in patients with grade II postoperative MR. The left atrial diameter, left ventricular end-systolic diameter, left ventricular end-diastolic and end-systolic volumes were larger in patients with a significant residual MR (P<.05). ConclusionThree-dimensional MV quantification did not predict the postoperative MR grade; however, the distance from the posteromedial papillary muscles to the leaflet border may be related to suboptimal repair results. Furthermore, excessive cardiac remodeling was related to postoperative MRgrade II, what could suggest a potential benefit of early surgical treatment.
