Left circumflex artery to left atrial fistula: A rare entity diagnosed on computed tomography angiography

A 60-year-old male, with a diagnosis of infrarenal abdominal aortic stenosis underwent coronary computed tomography angiography (CTA) as part of pre-surgical evaluation. Review of CTA images demonstrated an anomalous fistulous communication between a dilated and tortuous branch (*) of the ostioproximal left circumflex (LCx) artery and the left atrium (LA). The tortuous vessel was seen coursing anterior to the LA, ultimately draining into it via a single communication (thick black arrow) in the anterior atrial wall near the ostium of the right superior pulmonary vein (Fig.

ConclusionThis case demonstrates that QAV stenosis can be treated using TAVI with good clinical outcomes.

We aimed to evaluate the burden of coronary artery disease (CAD) using the computed tomography (CT) Leaman score in low-risk transcatheter aortic valve implantation (TAVI) patients. The extent of CAD in low-risk patients with aortic stenosis (AS) who are candidates for TAVI has not been accurately quantified. The CT Leaman score was developed to quantify coronary CT angiography (CCTA) atherosclerotic burden and has been validated to evaluate the extent of CAD. CT Leaman score>5 has been associated with an increase in major adverse cardiac events over long-term follow-up.

This study sought to derive and validate a systematic method enabling AVC quantification using computed tomography angiography (CTA) in patients with AS.Methods134 consecutive patients with AS who underwent both NCCT and CTA were included in the study and sub-divided into derivation (n=71) and validation cohorts (n=63). On NCCT, AVC was quantified using Agatston method utilizing the software developed for semi-automatic assessment of coronary calcium. On CTA, mean contrast attenuation of aorta (AortaHU) and standard deviation (SD) was measured in the region-of-interest at level of sinotubular junction.ResultsUsing an adjus...

Computed tomography angiography derived global longitudinal strain (CTA-GLS) has been shown to be feasible, however its prognostic value remains unclear in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). We evaluated the association of baseline CTA-GLS with outcomes including all-cause mortality and composite endpoint of death and heart failure hospitalization in 223 patients treated with TAVR. Patients with normal LVEF but reduced CTA-GLS had similar event rate to those with impaired LVEF, and higher than those with normal LVEF and preserved CTA-GLS. Baseline CTA-GLS assessme...

ConclusionDue to the low incidence of abnormal origin of coronary artery among adults, this condition is often misdiagnosed as coronary artery spasm, resulting in delayed management. Lack of timely surgical intervention may lead to a poor prognosis.

A 81-year-old male patient with chronic obstructive lung disease, decompensated severe calcified aortic stenosis, moderately to severely reduced biventricular systolic function, and atrial fibrillation with secondary pulmonary hypertension was referred to our institution. He was treated with diuretics, oral anticoagulants followed by low dose beta blocker. After cardiac recompensation coronary artery disease was excluded by coronary angiogram. Computed tomography (CT) angiography was performed prior to transcatheter aortic valve replacement (TAVR). Unexpectedly, CT (Panel C) and transthoracic echocardiography without contr...

CONCLUSION: MDCT is superior to 3-D TEE in terms of sizing accuracy and clinical outcomes. Reduction of PVR after TAVR with MDCT is likely due to valve annulus undersizing by TEE. PMID: 30972479 [PubMed - as supplied by publisher]
