The party balloon inflation maneuver increases intrathoracic pressure, decreases venous return, and after release enhances venous return to the right atrium more effectively than does the conventional Valsalva maneuver. Therefore, it shows potential for more effective detection of right-to-left shunts in patients with a patent foramen ovale. ().

Background: The distribution of radiation exposure on the body surface of interventional echocardiographers during structural heart disease (SHD) procedures is unclear.

Objectives: This study estimated and visualized radiation exposure on the body surface of interventional echocardiographers performing transesophageal echocardiography by computer simulations and real-life measurements of radiation exposure during SHD procedures.

Methods: A Monte Carlo simulation was performed to clarify the absorbed dose distribution of radiation on the body surface of interventional echocardiographers.

Diosmin (DSN) is found mainly in citrus fruits, and has potent antioxidant effects. This study aimed to evaluate pharmacokinetics of diosmetin-7-glucoside-γ-cyclodextrin (DIOSG-CD) inclusion complex. The area under the curve values from AUC0-24 of DIOSG-CD, prepared by reacting DSN and naringinase with γ-CD, were approximately 800-fold higher than those of DSN following their administration in Sprague-Dawley rats.

We present 2 cases that both developed infective endocarditis and underwent mitral valve replacement. In addition to positive blood culture and echocardiographic findings, such as vegetation or mitral valve perforation, the 16S ribosomal RNA gene amplicon sequence approach used was helpful for disease diagnosis.

Background: Recently, the Valve Academic Research Consortium (VARC)-3 criteria redefined bioprosthetic valve dysfunction (BVD) after transcatheter aortic valve implantation (TAVI). However, the rate of BVD is scarcely reported in current practice.

Aims: We aimed to evaluate the rate and predictors of BVD after TAVI based on the VARC-3 criteria.

Hesperetin glucosides such as hesperidin and hesperetin-7-glucoside are abundantly present in citrus fruits and have various pharmacological properties. However, the potential toxicity of hesperetin glucosides remains unclear. An initial assessment of the safety of hesperetin-7-glucoside-β-cyclodextrin inclusion complex (HPTGCD) as a functional food ingredient was undertaken to assess toxicity and mutagenic potential.

Flavonoids are biologically active natural products of great interest for their potential applications in functional foods and pharmaceuticals. A hesperetin-7--glucoside inclusion complex with β-cyclodextrin (HEPT7G/βCD; SunActive HCD) was formulated via the controlled enzymatic hydrolysis of hesperidin with enzyme. The conversion rate was nearly 98%, estimated using high-performance liquid chromatography analysis.

Saline contrast echocardiography requires an adequate provocation method for the detection of patent foramen ovale. The party balloon inflation maneuver during saline contrast transthoracic echocardiography is easy to explain to patients and objectively assesses the performance of provocative maneuvers by a clinician by watching balloon inflation.

The pharmacokinetics of compounds comprising hesperetin-7-glucoside with β-cyclodextrin and physically mixed hesperidin/dextrin was compared in 8 healthy adult male subjects in a nonrandomized, double-blind, cross-over, controlled study. For 0-24 h, the area under the curve of the total plasma hesperetin concentration after hesperetin-7-glucoside with β-cyclodextrin consumption was >100-fold higher than that after hesperidin/dextrin consumption.
