Heart amyloidosis scintigraphy

With the advent and optimization of nuclear scintigraphy protocols using bone-avid radiotracers, cardiac amyloidosis caused by transthyretin protein (ATTR) can now be diagnosed noninvasively without a costly tissue biopsy. The radiotracer 99mTc-pyrophosphate (99mTc-PYP) binds to deposited ATTR amyloid fibrils in the myocardium and can be visualized using planar and SPECT imaging. Validated in cohorts of patients with heart failure and echocardiographic and/or cardiac magnetic resonance imaging findings suggestive of cardiac amyloidosis, cardiac scintigraphy can confirm the diagnosis of ATTR-CM only when combined with blood and urine testing to exclude a monoclonal protein. Several scintigraphic tracers allow the visualization of amyloid deposits, but the most used are the bone tracers (99mTc-DPD, 99mTc-HMPD, 99m Tc- MPD, 99m Tc-PYP) [ 1 ]. They bind to cardiac amyloid deposits with a very good sensitivity for transthyretin amyloidosis (hereditary or senile), while AL amyloidosis absorbs these tracers only slightly. Several case reports and larger studies dating back to the 1980s have described the utility of 99m Tc-PYP, as used in this study, in identifying cardiac amyloidosis.

(-) monoclonal protein, (-) scintigraphy scan: unlikely to have cardiac amyloidosis, consider cardiac MRI and possible biopsy if suspicion is still high. (-) monoclonal protein, (+) scintigraphy scan: if grade 2 or 3 uptake on the scan then this is diagnostic for ATTR cardiac amyloidosis and no biopsy is needed, if grade 1 uptake then will need a biopsy to confirm diagnosis.

Nuclear scintigraphy offers comparable performance in diagnosing cardiac amyloidosis but can also reliably differentiate ATTR from AL amyloidosis affecting the heart, when combined with a monoclonal protein screen. Heart transplantation For hereditary ATTR amyloidosis, combined heart and liver transplant has been performed in a few dozen cases around the world. This operation is only an option for a very small minority of patients, and it carries significant risks.

Cardiac ATTR amyloidosis is an under-recognized cause of diastolic heart failure with preserved ejection fraction in elderly patients. 12,15 While AL amyloidosis is relatively rare, ATTR amyloidosis has been identified in up to 10–16% of elderly heart failure patients and is also common in patients with severe aortic stenosis. 12,15–17 Older autopsy studies have shown cardiac ATTR amyloid

a Early image acquired after 15 min after tracer administration, b late image acquired after 4 h post injection. The majority of cases of cardiac ATTR can now be diagnosed using a cardiac amyloid scintigraphy scan using bone tracers without the need for biopsy But biopsy is required if a monoclonal gammopathy is present as light chain amyloidosis can also show positive cardiac amyloidosis scintigraphy uptake Se hela listan på ahajournals.org Validated in cohorts of patients with heart failure and echocardiographic and/or cardiac magnetic resonance imaging findings suggestive of cardiac amyloidosis, cardiac scintigraphy can confirm the diagnosis of ATTR-CM only when combined with blood and urine testing to exclude a monoclonal protein.

Cardiac amyloidosis is a disease in which misfolded proteins aggregate into amyloid fibrils and deposit into the heart, leading to predominantly diastolic heart failure and ultimately death.1Nuclear imaging with technetium-99 m pyrophosphate (TcPYP) has evolved since the initial description in patients with myocardial infarction to reliably detect transthyretin type (ATTR) cardiac amyloidosis.

We conclude that 99mTc-DPD scintigraphy is a Aug 18, 2017 21 Importantly, all patients underwent planar 99mTc-HMDP total body scintigraphy and not SPECT imaging. All patients with TTR-CA had cardiac Rationale: Cardiac amyloidosis, considered for the last years to be a rare disease , is one of the. Cardiac means related to the heart.
