Severe retrograde dissection extending into the sinus of Valsalva is a rare complication during percutaneous coronary intervention (PCI), but life threatening. There is some literature about this complication, but this particular complication has not been previously reported in China. We present a case of coronary artery dissection during a PCI in which progressively extended retrogradely into ...

Hypertrophic obstructive cardiomyopathy (HOCM) is characterized by a dynamic left ventricular outlet tract (LVOT) obstruction, which may be exacerbated by reduced preload and Valsalva. Laparoscopic adjustable gastric band (LAGB) placement is a restrictive bariatric procedure which may be complicated by recurrent vomiting and Valsalva. Pre-operative cardiac evaluation of patients scheduled for L...

Cardiovascular responses to the Valsalva manoeuvre were examined in 19 non-diabetic subjects and 32 diabetic patients, some with signs of autonomic dysfunction. All the non-diabetic subjects showed an overshoot in systemic arterial pressure and a bradycardia after the manoeuvre, and in 11 of them only forearm vasoconstriction occurred. However, in eight non-diabetic subjects a forearm vasodilat...

Anomaly of the left anterior descending (LAD) coronary artery arising from the right sinus of valsalva is frequently seen with tetralogy of Fallot (TOF). The association of the LAD coronary artery with ventricular septal defect (VSD) is uncommon. We described an anomalous origin of the LAD coronary artery from the right sinus of valsalva with ventricular septal defect in a 38-year-old male pati...

BACKGROUND Transient global amnesia is reported to be caused by cerebral venous congestion. Internal jugular venous flow reversal in particular with the Valsalva maneuver leads to cerebral venous congestion. In addition, Valsalva maneuver can also induce subarachnoid hemorrhage. Transient global amnesia and subarachnoid hemorrhage might have common a pathophysiology in cerebral venous congestio...

PURPOSE Biologic valved-conduit grafts avoid the need for anticoagulation and can exploit the excellent hemodynamic performance of stentless valves. Incorporation of sinuses of Valsalva into the neoaortic root can improve the function of the stentless valves. DESCRIPTION Here we present a novel prefabricated stentless valved conduit incorporating sinuses of Valsalva and describe the technique...

Different components of the autonomic nervous system may be affected by different disorders to varying degrees. The aim of this study is to report first experiences with a new device (FAN(R), Schwarzer, Germany) which measures heart rate variability (HRV), sympathetic skin responses (SSR) and the pulse wave transit time (PTT). We examined 190 healthy volunteers (102 men, 88 women) and in 89 sub...

BACKGROUND AND PURPOSE Impaired autonomic function is common in the acute poststroke phase but little is known about the longer term effects, particularly in older people. We sought to determine if autonomic function is impaired after stroke recovery in older patients. METHODS A cross-sectional case-control study comparing autonomic function in 76 nondemented stroke patients with 70 community...

Purpose The placement of a pulmonary artery catheter sometimes needs long time by observing the pressure wave, and several factors have been reported to hinder the placement. In the present study, we examined whether enlargement of the aortic root is associated with longer time for the placement. Method We examined the time required for the catheter placement. The catheter placement time was ...

PURPOSE To investigate whether changes in hemodynamics induced by Valsalva maneuver can be exploited for detecting and characterizing breast lesions by optical mammography. MATERIALS AND METHODS 30 women underwent optical imaging of the breast using a DYNOT 232 system and performing Valsalva maneuvers prior to biopsy. Changes in light absorption due to changes in oxyhemoglobin and deoxyhemogl...
