BACKGROUND The Valsalva manoeuvre is an internationally recommended treatment for supraventricular tachycardia, but cardioversion is rare in practice (5-20%), necessitating the use of other treatments including adenosine, which patients often find unpleasant. We assessed whether a postural modification to the Valsalva manoeuvre could improve its effectiveness. METHODS We did a randomised cont...

A clinical case of successful radiofrequency ablation ventricular tachycardia with para-Hisian localization the substrate by access from right coronary sinus Valsalva is presented.

Interactions between the cardiovascular responses to the Valsalva manoeuvre and sustained handgrip were analysed in 5 men with untreated mild hypertension and 4 young normal subjects. Though set at a higher level, there was a normal blood pressure response to the Valsalva manoeuvre during concurrent sustained handgrip in 4 of the 5 hypertensive subjects. At the end of the handgrip period in whi...

dissection of the sinus of valsalva is a rare and life-threatening event. it often occurs during percutaneous coronary intervention in the right coronary artery (rca). dissection flap usually involves the rca and the right sinus of valsalva. here we report two extremely rare cases of spontaneous dissection limited to the non-coronary sinus of valsalva, causing severe aortic valve regurgitation:...

Sinus of Valsalva aneurysm rupture is a rare cardiac anomaly and demands prompt treatment. We present a case of a young patient who underwent transcatheter closure due to a ruptured sinus of Valsalva aneurysm.

PURPOSE The aim of our study was to assess the hemodynamic change of liver during the Valsalva maneuver using Doppler ultrasonography. METHODS Thirty healthy men volunteers were enrolled (mean age, 25.5±3.64 years). The diameter, minimal and maximal velocities, and volume flow of intrahepatic inferior vena cava (IVC), middle hepatic vein (MHV), and right main portal vein (RMPV) was measured d...

In The Lancet, Andrew Appelboam and colleagues present the fi ndings of a simple but clinically relevant investigation of a safe and non-invasive treatment for patients with stable supraventricular tachycardia who present to emergency departments. This topic is important because patients with supraventricular tachycardia are common, often recurrent, emergency department attenders, and can requi...

BACKGROUND Valsalva retinopathy is a rare but sight-threatening condition with sudden visual loss. Twin-pregnancy is known as a confirmed risk factor for Valsalva retinopathy. CASE REPORT A 21-year-old twin-pregnant Chinese woman with 31 weeks of gestation complained of a sudden decrease of visual acuity in her right eye for five hours. Based on the patient's medical history, clinical findings,...
