Methods Indices of LV structure and function were obtained by cardiac magnetic resonance imaging (CMRI). CAN was assessed by cardiovascular reflex testing (R-R response to paced breathing, Valsalva ratio, and blood pressure response to standing). Analyses were performed in 966 DCCT/EDIC participants with valid CMRI and CAN data (mean age 51 years, 52% men, mean diabetes duration 29 years, and m...

Sympathetic and parasympathetic function and somatic nerve conduction were assessed in ten patients with diphtheritic neuropathy and 28 controls. None of the patients had postural hypotension. The Valsalva ratio was abnormal in two patients who also had myocarditis, but it was normal in five cases. Cardiac vagal dysfunction was found in five patients. One case showed cardiac parasympathetic den...

Aneurysm of the sinus of Valsalva is a rare cardiac abnormality. Unruptured sinus of Valsalva aneurysm is usually asymptomatic, however, a ruptured aneurysm typically leads to an aortocardiac shunt and progressively worsening heart failure. We report a case of a 17-year-old male who suffered an aneurysm of the sinus of Valsalva rupture into the right atrium who manifested sudden dyspnea and acu...

purpose : the objective of this study was to investigate the causes, the clinical presentation, and treatment modalities in patients with valsalva premacular hemorrhage. methods : this case series study included 21 eyes of 21 patients referred to retina clinic of farabi eye hospital and two private eye clinics during 2001-2006 with sudden loss of vision and clinical diagnosis of premacular hemo...

A 70-year old man with a 15-year-history of chronic daily Valsalva maneuvers for left ear congestion presented with worsening vertigo and calvarial (occipitoparietal) and upper cervical hyperpneumatization. With continued frequent Valsalva maneuvers, subsequent studies demonstrated increased pneumatization with extension of air into the epidural space, causing mass effect on the left parietal l...

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:...
