Objectives Consistently variable with several peaks in heart rate histogram (e.g. bigeminy and trigeminy) is one of the arrhythmia types. We investigated the effects of gating error by consistently variable patients on left ventricular (LV) functional with cadmium zinc telluride (CZT) camera. The purpose of this study is to evaluate LV functional parameters by setting different heartbeat acceptance windows on gated myocardial perfusion single-photon emission computed tomography (SPECT) (MPS) in consistently variable patients, using echocardiography (echo) as a reference. Materials and methods Sixteen consistently variable patients underwent the gated MPS using a D-SPECT. The MPS images were obtained by setting two different types of heartbeat acceptance windows. The heartbeat acceptance windows were set to include only one peak and two peaks of the maximum count peaks, respectively. Results Mean end-diastolic volume, end-systolic volume and left ventricular ejection fraction (LVEF) were 112.7 mL, 62.2 mL and 51.3% for one peak, 114.5 mL, 66.1 mL and 47.1% for two peak, and 113.0 mL, 54.2 mL and 54.1% for echo, respectively. The mean differences between two peaks and echo in LVEF were larger than those of between one peak and echo. Conclusion Our study suggests that setting the heartbeat acceptance window of one peak was suitable for accurate measurement of LV function in consistently variable patients.

In patients who had undergone cardiac surgery (coronary artery bypass graft) and whose hearts showed abnormal movement during the cardiac cycle, we studied the accuracy of functional assessment using ECG-gated single-photon emission tomography (SPET) and the automated software developed by Germano et al. by comparing the findings with magnetic resonance (MR) images acquired three-dimensionally. Sixteen patients who had undergone cardiac surgery underwent 99mTc-sestamibi gated SPET (MIBI-g-SPET) and MRI on the same day. Left ventricular end-diastolic and end-systolic volumes (EDV, ESV) and ejection fraction (LVEF) were measured using MIBI-g-SPET and the aforementioned algorithm. Regional wall thickening was assessed using a four-point scale on MIBI-g-SPET and cine MRI. There was a good correlation between MIBI-g-SPET and MRI in respect of EDV (r=0.89), ESV (r=0.93) and LVEF (r=0.89). A high degree of agreement was found between the wall thickening scores obtained by MIBI-g-SPET and MRI in total segments (kappa=0.62) and in septal segments (kappa=0.67). It is concluded that ECG-gated perfusion SPET can provide regional and global functional information, including absolute volumes, in patients following cardiac surgery.

Antonio e Terezinha que construíram com dedicação e amor todos os degraus fundamentais da nossa escalada. Indescritível seria se fisicamente vivenciassem este momento, mas aí encontra-se o Deus magnânimo. Igualmente à memória de meu tio Luciano, com seu legado de sabedoria e exemplo de desprendimento, um dos meus maiores esculápios. Aos verdadeiros artífices de toda a minha existência, Haydeé, Felipe, Fabio e Rafael seriam volumes com páginas incontáveis se conseguisse traduzir a felicidade e o privilégio que tenho convivendo com vocês. As provas que passamos só nos fortaleceram. AGRADECIMENTOS À minha inesquecível orientadora, Profa. Dra. Amanda Guerra Moraes Rego Souza, por brindar-me com uma convivência sábia, competente e impecável, plena de conhecimentos e de qualidades morais. Foram ensinamentos marcantes, com um entusiasmo insuperável. Este privilégio só têm aqueles que compartilharam. Ao Dr. Romeu Meneghelo, mestre primeiro, que incentivou, apoiou e ensinou-me em momentos pessoais e profissionais decisivos. Aqui, a admiração e orgulho pela parceria honesta e pura de todos estes anos. À Dra. Paola Smanio, primorosa observadora desta pesquisa. Sua fidelidade, capacidade profissional e dedicação estarão sempre em meu coração. Ao Dr. Rodolfo Staico, pela competência, paciência sobretudo, nas revisões dos estudos angiográficos, além da verdadeira reciclagem de conhecimentos. Ao Dr. Ibraim Pinto, desde a reavaliação das angiografias e dos ultra-sons até as elaborações finais. O seu respeito e amizade foram sempre impressionantes. À Dra. Roselei Graebin e Vinícius Daher Vaz, pela prontidão, zêlo extremo e seriedade na análise dos exames de ultra-som intracoronário .
