OBJECTIVES: Reinforcements for the pulmonary autograft (PA) in the Ross operation have been introduced to avoid the drawback of conduit expansion and failure. With the aid of an in silico simulation, the biomechanical boundaries applied to a healthy PA during the operation were studied to tailor the best implant technique to prevent reoperation. METHODS: Follow-up echocardiograms of 66 Ross procedures were reviewed. Changes in the dimensions and geometry of reinforced and non-reinforced PAs were evaluated...

BACKGROUND: Maintenance of orthostatism requires the interaction of autonomic and muscle responses for an efficient postural control, to minimize body motion and facilitate venous return in a common type of syncope called neurocardiogenic syncope (NCS). Muscle activity in standing position may be registered by surface electromyography, and body sway confirmed by displacement of the center of pressure (COP) on a force platform. These peripheral variables reflect the role of muscles in the maintenance of orthostatism during the active tilt test, which, compared with muscle activity during the passive test (head-up tilt test), enables the analyses of electromyographic activity of these muscles that may anticipate the clinical effects of CNS during these tests...

OBJECTIVES: To use Z scores to quantify hiatal distensibility and to test the performance of Z scores for levator hiatal areas in predicting substantial pelvic organ prolapse (POP). METHODS: We undertook a retrospective study of the data from 145 nulliparas and 166 patients with POP who had a clinical POP examination with 3-dimensional translabial ultrasonography. Z scores were used to normalize levator hiatal areas of nulliparas. The Z score model for the hiatal area was built by the formula Z score = (measured value - predicted mean value)/predicted standard deviation and was used to evaluate hiatal ballooning in women with POP...

OBJECTIVES: Anomalous aortic origin of a coronary artery (AAOCA) from the opposite sinus of Valsalva is a rare cardiac anomaly associated with sudden cardiac death (SCD). Single-center studies describe surgical repair as safe, although medium- and long-term effects on symptoms and risk of SCD remain unknown. We sought to describe outcomes of surgical repair of AAOCA. METHODS: We reviewed institutional records for patients who underwent AAOCA repair, from 2001 to 2016, at 2 affiliated institutions...

OBJECTIVES: To describe the use of fractional flow reserve (FFR) and intravascular ultrasound (IVUS) in the evaluation of patients with anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS). BACKGROUND: ACAOS of the right and left coronary are rare, but may lead to symptoms and impose a risk for sudden cardiac death, depending on several anatomical features. Assessment and risk estimation is challenging in (nonathlete) adults, especially if they present without symptoms or with atypical complaints...

BACKGROUND: In dogs, due to better alignment with the aortic outflow, the subcostal (SC) transducer site provides greater Doppler-derived velocities than those obtained from the left parasternal view. The feasibility of this imaging approach has never been described in equine echocardiography. OBJECTIVES: To evaluate the feasibility of the SC view in newborn foals and compare aortic two-dimensional and Doppler-derived velocity measurements with those of standard parasternal long-axis (LAX) views...

To describe the baseline hemodynamic variables and response time of hemodynamic changes associated with the Valsalva maneuver using noninvasive continuous cardiac output monitoring (Nexfin). Hemodynamic monitoring provides an integral component of advanced clinical care and the ability to monitor response to treatment interventions. The emergence of noninvasive hemodynamic monitoring provides clinicians with an opportunity to monitor and assess patients rapidly with ease of implementation. However, the responsiveness of this method in tracking dynamic changes that occur has not been fully elucidated...

Anomalous origin of a coronary artery from the opposite sinus of Valsalva (ACAOS) is a rare malformation traditionally considered "malignant" in cases of interarterial course. Recently, a protective effect of the low interarterial subtype (between the aorta and the right ventricle outflow tract) has been described. We present an IVUS-guided percutaneous intervention in a patient with anomalous origin of the left coronary artery from the right coronary sinus presenting with anterior ischemia. In patients with ACAOS, the integration of complementary image techniques is recommended, defining the anomalous course of the vessel and providing an accurate assessment of the individual risk for each patient...

BACKGROUND: Digital intravaginal palpation remains the favored method for clinical assessment of pelvic floor muscle (PFM) function in women; however, there is growing interest in using transperineal ultrasound imaging (TPUSI). TPUSI does not involve vaginal penetration, making it particularly relevant for PFM assessment in women with genito-pelvic pain and penetration disorders. AIMS: To study the relations between measures of PFM morphology and function assessed using 3-dimensional (3D) TPUSI and PFM assessment through intravaginal palpation...

Controversies have been associated with the etiology, diagnosis, evaluation, and management of otosclerosis since Valsalva first described stapes fixation as a cause of hearing loss. Although the exact mechanism of the bone remodeling associated with otosclerosis remains uncertain, stapedotomy has been accepted as the surgical treatment of most patients with stapedial otosclerosis. There remains a disparity of opinion, however, regarding the role of preoperative imaging, surgical technique, implant selection, and medical therapy for cochlear otosclerosis...

Cardiovascular autonomic neuropathy (CAN) is a major complication of type 1 diabetes (T1D). This study aimed to evaluate cardiac autonomic nervous system (ANS) function in children with T1D and its relation to different demographic, clinical and laboratory variable. This cross-sectional study included 60 children with T1D (mean age = 15.1 ± 3.3 years; duration of diabetes = 7.95 ± 3.83 years). The following 8 non-invasive autonomic testing were used for evaluation: heart rate at rest and in response to active standing (30:15 ratio), deep breathing and Valsalva maneuver (indicating parasympathetic function); blood pressure response to standing (orthostatic hypotension or OH), sustained handgrip and cold; and heart rate response to standing or positional orthostatic tachycardia syndrome or POTs (indicating sympathetic function)...

Sinus of Valsalva aneurysm is a rare cardiac anomaly with wide spectrum of clinical presentation ranging from asymptomatic state to dreadful complications due to compression of vital surrounding structures or aortic dissection. There are only few reported cases of sinus of Valsalva aneurysm presented with cardiac arrhythmias including complete heart block. We herein, present a case of a 50 year male who presented with complete heart block. A large noncoronary sinus of Valsalva aneurysm compressing the surrounding atrioventricular junctional tissue was detected incidentally during echocardiographic study, which was considered to be the cause of patient's complete heart block...
