ACCF/ASNC appropriateness criteria for single-photon emission computed tomography myocardial perfusion imaging (SPECT MPI): a report of the American College of Cardiology Foundation Quality Strategic Directions Committee Appropriateness Criteria Working Group and the American Society of Nuclear Cardiology endorsed by the American Heart Association.

Under the auspices of the American College of Cardiology Foundation (ACCF) and the American Society of Nuclear Cardiology (ASNC), an appropriateness review was conducted for radionuclide cardiovascular imaging (RNI), specifically gated single-photon emission computed tomography myocardial perfusion imaging (SPECT MPI). The review assessed the risks and benefits of the imaging test for several indications or clinical scenarios and scored them based on a scale of 1 to 9, where the upper range (7 to 9) implies that the test is generally acceptable and is a reasonable approach, and the lower range (1 to 3) implies that the test is generally not acceptable and is not a reasonable approach. The mid range (4 to 6) implies that the test may be generally acceptable and may be a reasonable approach for the indication. The indications for this review were primarily drawn from existing clinical practice guidelines and modified based on discussion by the ACCF Appropriateness Criteria Working Group and the Technical Panel members who rated the indications. The method for this review was based on the RAND/UCLA approach for evaluating appropriateness, which blends scientific evidence and practice experience. A modified Delphi technique was used to obtain first- and second-round ratings of 52 clinical indications. The ratings were done by a Technical Panel with diverse membership, including nuclear cardiologists, referring physicians (including an echocardiographer), health services researchers, and a payer (chief medical officer). These results are expected to have a significant impact on physician decision making and performance, reimbursement policy, and future research directions. Periodic assessment and updating of criteria will be undertaken as needed.

Contrast echocardiography improves the diagnostic yield of transthoracic studies performed in the intensive care setting by novice sonographers.

BACKGROUND: Bedside portable echocardiography in the intensive care department (ICU) is technically difficult, but crucial for directing patient care. Prior studies have shown contrast echocardiography (CE) in the ICU clarifies left ventricular wall motion when performed by experienced sonographers (ESO). However, in most hospitals, ESO are unavailable around the clock, and less experienced cardiovascular fellows or trainees may be asked to perform these examinations. METHODS: Transthoracic echocardiograms were retrospectively evaluated by level III trained echocardiographers for 213 patients in the ICU. Most were performed to assess left ventricular function (65% or 139 of 213) and were scanned by cardiology fellows (70% or 149 of 213) with less than 3 months echocardiography experience. Contrast agent was used in 29% (62 of 213) of all patients. RESULTS: The conversion of suboptimal or diagnostically inadequate apical 4- and 2-chamber views to diagnostically adequate with contrast was statistically significant when performed by both cardiology fellows and ESO (Fischer exact test, P < .0002). CONCLUSIONS: CE is effective in improving the diagnostic yield of transthoracic echocardiographic ICU studies performed by both novice sonographers and ESO. Using cardiology fellows to perform CE in this setting can be appropriate, particularly in after-hour situations, when ESO are not always available and the clinical question is left ventricular function. Results also suggest cardiology fellows can easily learn CE.

Meeting highlights of the 15th annual Scientific Sessions of the American Society of Echocardiography: June 26 to 30, 2004.

"Echocardiography is the heart of clinical cardiology" was an appropriate theme for the 15th Scientific Sessions of the American Society of Echocardiography. Care of the cardiovascular patient is constantly changing, and this meeting showcased how echocardiographic and Doppler methods continue to be critically important to detect and quantify disease, determine response to therapy, and guide clinical decision making in contemporary medicine. This highly successful five-day educational event attracted a record number of attendees and focused on disease-based clinical applications of the latest technological advances in cardiac ultrasound, including advances in diagnosis and treatment of heart failure, valvular disease, coronary disease, and congenital disease.

Duration of abnormal SPECT myocardial perfusion imaging following resolution of acute ischemia: an angioplasty model.

OBJECTIVES: This study was designed to determine how long nuclear myocardial perfusion imaging (MPI) remains abnormal following transient myocardial ischemia. BACKGROUND: Acute rest MPI identifies myocardial ischemia with a high sensitivity when the radionuclide is injected during chest pain. However, the sensitivity of this technique is uncertain when the radionuclide is injected following the resolution of symptoms. METHODS: Forty patients undergoing successful coronary angioplasty were randomized into four equal groups. Tc-99m sestamibi was injected intravenously during the last balloon inflation (acute MPI) in 30 patients and then reinjected 1, 2, or 3 h later (delayed MPI). In a fourth group, the radiopharmaceutical was injected at 15 min following balloon deflation (delayed MPI). A final injection was performed at 24 to 48 h (late MPI) in 37 patients (93%). RESULTS: A perfusion defect was detected in all 30 acute MPI studies; in 7/10 patients (70%) injected at 15 min; in 11/30 patients (37%) injected at 1, 2, or 3 h; and in 7/37 patients (19%) injected at 24 to 48 h. Perfusion scores were 13.0 +/- 9.2 on acute MPI, 5.1 +/- 2.8 at 15 min (p < 0.001 vs. acute MPI); 2.6 +/- 3.0 at 1, 2, and 3 h (p < 0.001 vs. acute MPI); and 1.3 +/- 2.4 at 24 to 48 h (p < 0.001 vs. acute MPI; p < 0.03 vs. delayed MPI). CONCLUSIONS: Myocardial perfusion imaging may remain abnormal for several hours following transient myocardial ischemia even when normal flow is restored in the epicardial coronary artery.
