ABSTRACT

In the midst of the coronavirus disease-2019 (COVID-19) pandemic, an 84-year-old female patient was admitted due to non-exertional syncope preceded by retrosternal pain. She had experienced a prolonged episode of oppressive chest pain 6 days before her presentation, but due to the concern of contracting COVID-19, she did not present for medical care. Upon admission to the emergency department, the patient was in circulatory shock, with her physical examination being remarkable for the presence of a holosystolic murmur. Admission electrocardiogram revealed an inferior ST-segment elevation with Q waves with extension to the posterior wall, consistent with subacute infarct in the right coronary artery (RCA) territory, and the patient was transferred for primary percutaneous coronary intervention. Upon arrival to the catheterization laboratory, a summary transthoracic echocardiogram was performed, which revealed inferior wall and infero-septal akinesia with an 18 mm ventricular septal rupture. Coronary angiography documented occlusion of the proximal segment of a dominant RCA. Due to a high perioperative risk, the patient underwent successful retrograde percutaneous closure with a 24 mm MemoPart™ device, with mild to moderate residual shunt. Despite an immediate clinical improvement, the patient died 12 hours after the procedure due to refractory cardiogenic shock.

ABSTRACT

This study aimed to determine the impact of systematic coronary computed tomographic angiography (CCTA) use following an abnormal non-invasive ischemia test (NIST) on patient selection strategy for invasive coronary angiography (ICA). In patients with suspected stable coronary artery disease (CAD), NIST use frequently results in sub-optimal diagnostic and revascularization yields of ICA. This randomized clinical trial, conducted at a single academic tertiary center, selected 220 symptomatic patients with mild-to-moderately abnormal NIST results who were referred for ICA. Patients received either the originally intended ICA (n = 105) or CCTA (n = 115). The primary endpoint was the diagnostic yield of ICA in each group. Revascularization yield and major adverse cardiovascular events at 12 months were also assessed. The patients were 69 ± 9 years old, 60% were men, and 31% had typical angina. Mean pre-test probability of obstructive CAD was 34%. Overall prevalence of obstructive CAD was 37.7% on the index angiographic procedure. In the CCTA group, ICA was cancelled by referring physicians in 83 patients (72.2%) after receiving CCTA results. For those undergoing ICA, diagnostic (84.4% vs. 41.7%, p<0.001) and revascularization (71.9% vs. 38.8%, p = 0.001) yields were significantly higher for CCTA-guided ICA than for standard NIST-guided ICA. Mean cumulative radiation exposure was significantly lower in the CCTA-guided ICA arm than in the NIST-guided ICA arm (12 ± 9 vs. 16 ± 10 mSv, respectively, p = 0.024). There were no significant differences in the primary safety endpoint rates between the strategies (p = 0.439). In patients with suspected CAD and mild-to-moderately abnormal ischemia tests, a diagnostic strategy including CCTA as a gatekeeper is safe and effective and significantly improves diagnostic and revascularization yields of ICA.

ABSTRACT

The benefits of patent foramen ovale (PFO) closure for cryptogenic stroke secondary prevention are still debated. The Risk of Paradoxical Embolism (RoPE) study developed a score to improve patient selection for this procedure. We proposed to assess the validity of this score to assess the prognostic impact of PFO closure.From 2000 to 2014, all consecutive patients submitted to PFO closure were included in a prospective registry in a university center. The primary endpoint was recurrent ischemic cerebrovascular events and the secondary endpoints were all-cause, neurological, and cardiac mortality rates and new-onset atrial fibrillation (NOAF) rates. In total, 403 patients were included in the study (women: 52.1%; mean age: 44.7 ± 10.9 years). The mean follow-up period was 6.4 ± 3.7 years. Immediate success was achieved in 97% patients. There were 23 (5.8%) ischemic cerebrovascular events, 8 (2.0%) deaths, and 17 (4.3%) NOAFs. The mean RoPE score was 6.10 ± 1.79. Smoker status, coronary artery disease, lower RoPE score, and higher left atrial dimensions were predictors of the primary endpoint. However, a lower RoPE score and coronary artery disease remained independent predictors in multivariate analysis.RoPE score was shown to be an independent predictor of recurrent ischemic cerebrovascular events, and a score of ≤ 6 was shown to identify patients with significantly higher risk of mortality and recurrent ischemic events.
