- Endovascular repair of ascending aorta pseudoaneurysm post-extracorporeal membrane oxygenation cannulation during pulmonary transplant(2023) KANAMORI, Lucas Ruiter; MULATTI, Grace Carvajal; BARROS, Taina Curado Gomes de; ABDALLA, Luis Gustavo; BIHAN, David Costa de Souza Le; LUCCIA, Nelson DeWe demonstrated an endovascular technique excluding an ascending aorta pseudoaneurysm using an aortic extension. A 32-year-old woman, 3 years after lung transplantation with extracorporeal membrane oxygenation presented with an ascending aortic pseudoaneurysm. Vascular surgery was consulted after open repair was deemed high risk. An aortic extension stent graft was placed in a hybrid operating room with the aid of intraoperative transesophageal echocardi-ography. Ascending aorta pseudoaneurysms are complex and life-threatening complications. Traditional repair involves high surgical and anesthetic risks whereas endovascular treatment is technically feasible.
- Echocardiographic assessment of atrial function in patients with hypertrophic cardiomyopathy with and without paroxysmal atrial fibrillation(2022) TEIXEIRA, Kamilla Leite Morbeck; CORREIA, Edileide de Barros; TRESSINO, Cintia Galhardo; PECANHA, Marcela Momesso; MELCHIOR, Walter Antonio; BARRETTO, Rodrigo Bellio de Mattos; MEDEIROS, Bruna Gomes de; BIHAN, David LeIntroduction and objectives: Hypertrophic cardiomyopathy (HCM) is accompanied by patho-physiological changes that predispose to the development of atrial fibrillation (AF). This arrhythmia impacts negatively on the morbidity, mortality and quality of life of these patients. Our objective was to evaluate the behavior of left atrial function, by means of atrial strain (derived from speckle tracking) and volumetric analysis by three-dimensional echocardiography, in patients with HCM with paroxysmal AF. Method: We analysed left atrial function in 53 patients with HCM, 25 of whom were paroxysmal AF carriers (mean age 61.7 +/- 9.9 years; 56% female) compared with 28 members of the control group (mean age 60.5 +/- 10 years; 53.6% female) who were matched especially for sex, age and other demographic data. Results: It was observed that patients with HCM and a history of paroxysmal AF had lower left atrial emptying fractions than individuals in the control group; and the active atrial emptying fraction was a factor independently associated with the presence of this arrhythmia (p=0.018; odds ratio=0.93). Moreover, we found a significant reduction of the left atrial strain in all its components in the total sample of patients, with no difference between the groups. Conclusions: Measurements of atrial emptying fractions by three-dimensional echocardiography allowed differentiating patients with HCM with and without paroxysmal AF.

- Evaluation of myocardial work in patients with resistant arterial hypertension(2022) HYGIDIO, Daniel de Andrade; BIHAN, David Le; SOUZA, Jonathan Batista; BARRETTO, Rodrigo Bellio de Mattos; JR, Wilson Mathias; SOUSA, Marcio Goncalves deAims Individuals with resistant arterial hypertension are particularly at risk of developing target organ damage and cardiovascular events. The advanced echocardiography technique called myocardial work (MW), through the analysis of the left ventricular pressure-strain loop, is among the possibilities for evaluating these individuals. Our study was designed to describe the behavior of MW indices in individuals with resistant arterial hypertension (RH), controlled hypertension (CH), and normal arterial pressure (N). Methods and Results Seventy-one patients underwent Ambulatory Blood Pressure Monitoring (ABPM) and were characterized into three groups after a medical consult: RH (subjects with hypertension on four or more antihypertensive medications despite having controlled blood pressure); CH (subjects with hypertension on up to two antihypertensive medications); and N (individuals with normal ABPM; not using any medications). Echocardiographic analysis was performed using the Vivid E95 ultrasound system and blood pressure was measured at the time of the examination and subsequently used to determine myocardial work indices. RH demonstrated lower global work efficiency (GWE, mean = .95%; p = .005) and higher global wasted work (GWW, mean = 114 mm Hg%; p = .011) compared to other groups. Left ventricular mass measured by three-dimensional echocardiography, systolic wall stress, relative wall thickness and peak systolic dispersion were inversely correlated to GWE. No difference was observed between CH and N groups regarding MW indices. On multivariate analysis, only systolic wall stress remained as an independent predictor of GWE, when controlled by 3D mass index, relative wall thickness, peak systolic dispersion, and the hypertension group. Conclusion Individuals with resistant hypertension have lower global work efficiency and higher global wasted work, compared to individuals with controlled hypertension and without arterial hypertension.
- Focused Endocardial Septal Ablation: A New Technique to Treat Postmyectomy Recurrent Gradient(2021) VALDIGEM, Bruno Pereira; CORREIA, Edileide Barros; MOREIRA, Dalmo Antonio Ribeiro; BIHAN, David Costa de Souza Le; PINTO FILHO, Ibraim Masciarelli; PALADINO FILHO, Antonio Tito; ABIZAID, Alexandre Antonio Cunha; VIESI, Joao Henrique Zucco; SANTOS, Tiago Senra Garcia dos; CHACCUR, PauloThis report describes the case of a 64-year-old woman with a previous diagnosis of obstructive hypertrophic cardiomyopathy who underwent surgical myectomy but who had a persistent midventricular residual gradient. The patient was symptomatic despite medical treatment and chose to undergo percutaneous radio frequency (RF) ablation focused on the gradient. RF delivery was performed, and the gradient was reduced from the initial 105/68 mm Hg (during Valsalva maneuver/at rest before ablation) to 24/10 mm Hg. This reduction was sustained for the next 12 months. Percutaneous RF ablation may be a reasonable option for second surgical myectomy, and the protocol can be easily reproduced.
