“…Although both contrast echocardiography and stress magnetic resonance first-pass perfusion have great potential for myocardial perfusion imaging, these two techniques have so far been studied in relatively small populations, are quite demanding and have thus far achieved only limited implementation in clinical practice [142,143]. Conversely, stress perfusion nuclear imaging has been used for approximately 30 years, and its value in heart disease has been extensively evaluated and demonstrated in very large patient groups [144].…”

Background Gating of single-photon emission computed tomography (SPECT) has significantly improved the reliability and diagnostic accuracy of myocardial perfusion imaging. The functional parameters derived from this technique, mainly left ventricular volumes and ejection fraction, have been demonstrated to be accurate and reproducible. They are able to increase the detection of severe and extensive coronary artery disease and show a significant incremental prognostic power over perfusion abnormalities. Therefore, the importance given to gated SPECT functional data has progressively grown. Discussion This circumstance has further expanded the indications for myocardial perfusion imaging and strengthened its position among the different imaging modalities. Moreover, several studies show that the evaluation of ventricular function may have a leading part in justifying the execution of perfusion scintigraphy in various clinical conditions. Aim Aim of this review is to describe this evolution of gated SPECT functional assessment from a supporting rank with respect to perfusion, to a main actor position in the field of cardiac imaging.

“…Cardiovascular magnetic resonance imaging (CMR) continues to enjoy an expanding role in the assessment of myocardial structure, function, and viability [20]. Late gadolinium enhancement (LGE) is a magnetic resonance technique with proven efficacy for the detection of myocardial infarction [21] and identification of secondary causes of heart failure [22], including myocarditis [23,24].…”

Background-New left ventricular systolic dysfunction affects 500,000 Americans and coronary artery disease (CAD) is responsible for two-thirds of cases. Identifying CAD has both prognostic and therapeutic implications. We evaluated the ability of late gadolinium enhancement (LGE) by cardiovascular magnetic resonance imaging (CMR) to detect CAD as the etiology of recent onset congestive heart failure (CHF).

Consecutive outpatients who had undergone the atrial switch operation or who had ccTGA without previous heart surgery were invited to participate. Patients with a permanent pacemaker in situ were excluded. All patients received routine clinical evaluation in the outpatient clinic, including determination of the grade of tricuspid regurgitation by echocardiography. The degree of tricuspid regurgitation was qualitatively assessed by color Doppler imaging and graded as 0 (no regurgitation), I (mild regurgitation), II (moderate Circ J 2008; 72: 1130 -1135 (Received July 1, 2007 revised manuscript received February 6, 2008; accepted February 25, 2008 Background Patients after atrial switch operation for transposition of the great arteries have limited exercise performance. Rigid atrial baffles may cause a relative preload reduction. Previous studies have had suboptimal control groups, which ideally should consist of patients with congenitally corrected transposition of the great arteries (ccTGA) without previous heart surgery, having a systemic right ventricle, but lacking rigid atrial baffles. Therefore the aim of this study was to test the impact of atrial baffles by comparing 12 atrial switch patients with 11 ccTGA patients. Methods and ResultsSystemic right ventricular stroke volume (SV), heart rate, cardiac index, and other parameters were assessed during rest and dobutamine stress magnetic resonance imaging. The most important difference between the groups was that the atrial switch patients could not increase SV during stress, whereas ccTGA patients increased it significantly. There was no difference between groups in the rise of the cardiac index. Heart rate increased significantly more in atrial switch patients than in ccTGA patients. ConclusionsThe results support the hypothesis that atrial baffles restrict a rise in SV under dobutamine stress in patients after atrial switch operation for transposition of the great arteries.
