Measurements of left ventricular systolic time intervals during the Valsalva manoeuvre have been made in IO normal subjects, 5 patients with ischaemic heart disease before and after treatment with a beta adrenergic blocking drug, and 5 patients with cardiomyopathy. The individual relation between the heart rate and the left ventricular ejection time was established in the normal subjects during...

Background: Supraventricular tachycardia (SVT) is a relatively common dysrhythmia among the general population and a common dysrhythmia presenting to the emergency department. Generally speaking, it is assumed the provider should attempt a vagal maneuver as first-line treatment for SVT, and the most common vagal maneuver used is the Valsalva. Current resources describing the method to perform t...

It is often challenging to assess cardiac filling pressure clinically. An improved system for detecting or ruling out elevated cardiac filling pressure may help reduce hospitalizations for heart failure. The blood pressure response to the Valsalva maneuver reflects left heart filling pressure, but its underuse clinically may be due in part to lack of continuous blood pressure recording along wi...

a ruptured sinus of valsalva aneurysm rarely accompanies the aortic and tricuspid valve endocarditis. a 36-year-old woman presented with low-threshold dyspnea on exertion and fever. transthoracic and transesophageal echocardiography showed a ruptured noncoronary sinus of valsalva aneurysm with large vegetations on the tricuspid and aortic valves, resulting in moderately severe tricuspid regurgi...

PURPOSE To evaluate a technique for contrast agent preparation as mixing the patients' blood with agitated saline and to compare it with agitated saline alone in diagnosis of cardiac right-to-left shunt in regard to their sensitivity, time window, and distribution of artificially induced microembolic signals. METHODS Fifty-two patients with stroke who had Transesophageal echocardiography prov...

OBJECTIVE To investigate the sympathetic and parasympathetic cardiovascular function in primary Sjögren's syndrome (SS) and to investigate the possible relation with ocular dryness. METHODS 41 (40 women) patients with primary SS, mean age 50 years (range 20-80) with a mean disease duration of eight years (range 1-30), were studied. In each patient direct arterial blood pressure (BP), heart ra...

OBJECTIVES The sinuses of Valsalva are known to contribute to the normal function of the aortic valve. Little is known about their role in promoting coronary artery blood flow. The aim of this study was to compare coronary artery flow characteristics among patients undergoing a Bentall operation by means of a conventional cylindrical Dacron conduit or with a new conduit with pseudosinuses of Va...

a 38-year-old man with a history of recurrent genital ulceration initially diagnosed as genital herpes was admitted after presenting with paroxysmal nocturnal dyspnea. echocardiography revealed aneurysm formation of the sinus of valsalva. on diagnosis of an aneurysm of the sinus of valsalva associated with behçet's disease (bd), surgeon repaired the affected sinus only, and continuous steroid t...

AIMS To report aortic root geometry by echocardiography in a large population of healthy, asymptomatic aortic stenosis (AS) patients in relation to current vendor-specified requirements for transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS Baseline data in 1481 patients with asymptomatic AS (mean age 67 years, 39% women) in the Simvastatin Ezetimibe in AS study were used. Th...

We performed this study to determine whether electrocardiographic corrected QT (QTc) interval predicts alterations in sympathovagal balance during orthostatic intolerance (OI). We reviewed 1,368 patients presenting with symptoms suggestive of OI who underwent electrocardiography and composite autonomic function tests (AFTs). Patients with a positive response to the head-up tilt test were classi...
