OBJECTIVE: Elevated central venous pressure is a major cause of morbidity and mortality after the Fontan operation. The difference between mean circulatory filling pressure and central venous pressure, a driving force of venous return, is important in determining dynamic changes in central venous pressure in response to changes in ventricular properties or loading conditions. Thus, noninvasive central venous pressure and mean circulatory filling pressure estimation may contribute to optimal management in patients undergoing the Fontan operation...

AIMS: The pathophysiological mechanism of incontinence is multifactorial. We evaluated the role of 3D-4D ultrasound in the assessment of the fascial supports of the urethra and the urethral sphincter complex (USC) for diagnosing stress urinary incontinence. METHODS: Observational case-control study in women with and without stress urinary incontinence attending a urogynecology service and a general gynecology service. All women were interviewed, examined, and classified according to the Pelvic Organ Prolapse Quantification (POP-Q) and underwent a 3D-4D translabial ultrasound...

Quadricuspid aortic valve is an extremely rare congenital heart anomaly that often causes valve incompetence, requiring surgical intervention. Care must be taken to avoid surgical complications in patients with quadricuspid aortic valve; thus, preoperative diagnosis is important. A 76-year-old man presented with exertional dyspnea due to aortic regurgitation. Transthoracic and transesophageal echocardiography revealed severe aortic regurgitation caused by quadricuspid aortic valve. To avoid interference with the cardiac conduction system, we performed aortic valve replacement using an ingenious technique, in which pledgeted sutures on the accessory leaflet were placed from outside the sinus of Valsalva to above the aortic annulus...

We describe the case of a 61-year-old male with a giant aortic root aneurysm associated with chronic aortic Type A dissection. The patient had been operated on 16 years before due to aortic annuloectasia with mechanical valve replacement. The patient underwent revision aortic surgery with a Bentall-De Bono operation with Svensson modification, using a #21 On-X Valsalva mechanical valve conduit. The postoperative course was uneventful.

Completely asymptomatic sinus of Valsalva aneurysms are rare entities, and there is no consensus regarding their management. We present the case of a patient who underwent atrial septal defect device closure at 5 years of age and was lost to follow-up, then presented 6 years later with unruptured sinus of Valsalva aneurysm and was closely followed. The aneurysm eventually ruptured and was successfully operated on with good outcomes.

BACKGROUND: Two-dimensional (2D) echocardiography is one of the most feasible, noninvasive methods for assessing the aortic diameter and biomechanical changes. We studied possible interfaces between noninvasive biomechanical and speckle-tracking (ST) echocardiographic data from dilated aortas. METHODS: Altogether, 44 patients with dilative pathology of ascending aorta (DPAA) were compared with subjects without ascending aortic dilation (diameter <40 mm). DPAA patients formed two groups based on diameter size: group 1, ≤45 mm diameter; group 2, >45 mm...

OBJECTIVES: The aim of this study was to evaluate dynamic two-dimensional (2D) and 3D transperineal pelvic ultrasound findings with urodynamic studies in women with lower urinary tract symptoms after midurethral sling placement. METHODS: On 2D images, the sling position, and on 3D imaging the sling angle, urethral diameter, urethral height, and urethral cross sectional area were recorded with and without Valsalva. Patients were categorized into 3 groups based on 2D imaging: group 1-at rest, the sling lies parallel to the urethral lumen, and during Valsalva, the sling becomes C shaped; group 2-both at rest and during Valsalva, the sling runs parallel to the urethral lumen; group 3-at rest, the sling is C shaped, and during Valsalva, this curved shape is maintained...

Sinus of Valsalva aneurysm accounts for only 1% of congenital cardiac anomalies. Sinus of Valsalva aneurysm can cause aortic insufficiency, coronary artery flow compromise, cardiac arrhythmia, or aneurysm rupture. Three-dimensional transesophageal echocardiography (3DTEE) represents an adjunctive tool to demonstrate the ruptured sinus of Valsalva with better delineation. We present an adult patient with rupture of noncoronary sinus of Valsalva aneurysm into the right atrium (RA). 3DTEE accurately delineated the site of rupture into the RA and showed the exact size and shape of the defect, which helped in the successful transcatheter closure of the defect with a duct occluder device...

Sinus of Valsalva aneurysms are rare cardiac abnormalities that may be congenital or acquired. Patch closure or direct closure of the aneurysm orifice is a frequently performed surgical repair strategy. In this report, we present a rare case of an isolated giant right sinus of Valsalva aneurysm with aortic insufficiency and right coronary artery obstruction. We treated this patient by a valve-sparing aortic root remodelling procedure with partial preservation of the intact Valsalva sinuses and coronary artery bypass grafting with a favourable outcome...

One hypothesized contributor to vision changes experienced by >75% of International Space Station astronauts is elevated intracranial pressure (ICP). While no definitive data yet exist, elevated ICP might be secondary to the microgravity-induced cephalad fluid shift, resulting in venous congestion (overfilling and distension) and inhibition of cerebrospinal and lymphatic fluid drainage from the skull. The objective of this study was to measure internal jugular venous pressure (IJVP) during normo- and hypo-gravity as an index of venous congestion...

Bicuspid aortic valve (BAV) disease is associated with aortic dilatation. Timing of follow-up and surgery is challenging. Hence, there is an unmet clinical need for additional risk stratification. It is unclear whether valve morphology is associated with dilatation rates. Therefore, the objective of this study was to examine the association between clinical and echocardiographic determinants (including valve morphology) and aortic dimension and the progression rate of dilatation.Aortic dimensions were assessed on serial echocardiographic images between 1999 and 2014 in a population of 392 patients with BAVs in a tertiary care center in the Netherlands...
