Résumé

Objective: Calcified coronaries still remain a major challenge for interventional cardiologist. This study aims to evaluate safety and efficacy of intravascular lithotripsy (IVL) in management of coronary artery calcification. Methods: This was a retrospective single centre study regarding the utility of IVL in management of calcified coronaries. Patients with hemodynamically stable acute coronary syndrome or symptomatic chronic coronary syndrome (CCS) and calcified coronaries on angiography and who underwent IVL were enrolled. Intravascular imaging was performed wherever feasible. The primary endpoint was procedural success. In addition, data regarding procedural complications were collected. Results: A total of 29 patients underwent IVL with a majority being males and having comorbidities such as hypertension and diabetes. A procedural success rate of 93.1% was achieved with no patient having >50% residual stenosis. IVL catheter was successfully delivered in all patients. The mean catheter diameter was 3.3 ± 0.4 mm and mean number of delivered pulses was 70.3 ± 16.4. The arteries most commonly intervened were the left main coronary and the left anterior descending artery. Intracoronary imaging revealed a significant increase in minimum luminal cross-sectional area (MLA) post IVL (preMLA: 5.1 ± 2.5 mm2 ; post-MLA: 10.7 ± 2.9 mm2 ; P<0.001). Two patients had in-hospital MACE in form of peri-procedural non Q-wave MI. No patient had arrhythmias, stent thrombosis, coronary perforation, or slow flow/no-reflow. Two patients had a rupture of IVL balloon while four had coronary artery dissection. Conclusions: IVL is a safe and highly effective modality with high procedural success rate in management of calcified coronaries.

Résumé

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is now recognized as a systemic disorder with many comorbidities. Atopy in patients with COPD and upper airways symptoms has not been characterized. OBJECTIVE: We investigated the occurrence and impact of aeroallergen sensitisation in patients with COPD and upper airways symptoms.

Résumé

BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) in children with asthma, not associated with cystic fibrosis, is yet to receive the recognition it deserves. OBJECTIVE: To highlight the presentation of ABPA in children with asthma. METHODS: This retrospective review documents the occurrence of pediatric ABPA over a period of 31 years in one unit. Children with asthma, eosinophilia and infiltrates on chest radiograph were screened for ABPA. In these patients, demonstration of immediate hypersensitivity response against Aspergillus species along with serological profile and pulmonary function testing were done. Bronchography/computed tomography (CT) of the chest demonstrated central bronchiectasis (CB). CT of the paranasal sinuses was done in patients with upper airways symptoms. In those suspected with allergic Aspergillus sinusitis (AAS) consent was sought from the parents for the invasive procedure needed for the diagnosis of AAS. RESULTS: Of the 349 patients with ABPA diagnosed, 42 (12.03%) were in the pediatric age group. The mean age on presentation was 12.9 ± 4 years with a male preponderance. All patients had asthma and positive intradermal/skin prick test against Aspergillus species. Ring shadows, the most common radiological presentation, were seen in 28 of 42 patients. Bronchography/CT of the chest demonstrated CB, a feature pathognomic of ABPA, in 32 of 42 patients. High attenuation mucus plugs was observed in 7 of 36 patients while ABPA-seropositive was diagnosed in 10 of 42 patients. On imaging, sinusitis was seen in 20 of 30 patients with upper airways symptoms of whom eight had suspected AAS. Three parents consented for surgery, which confirmed the diagnosis. CONCLUSION: This study highlights the need to evaluate asthmatic children for ABPA as also to exclude AAS.
