RESUMEN
BACKGROUND: COronaVIrus Disease 19 (COVID-19) led to the reorganization of Cardiology Units in terms of working spaces and healthcare personnel. In this scenario, both outpatient visits and elective interventional cardiology procedures were suspended and/or postponed. We aimed to report the impact of COVID-19 on interventional coronary and structural procedures in Piedmont, Italy. METHODS: The number of coronary angiographies (CAG), percutaneous coronary interventions (PCI), primary PCI (pPCI), transcatheter aortic valve replacements (TAVR) and Mitraclip performed in Piedmont between March 1st and April 20th, 2020 (CoV-time) were collected from each catheterization laboratory and compared to the number of procedures performed the year before in the same months (NoCoV-time). RESULTS: Procedural data from 18 catheterization laboratories were collected. Both coronary (5498 versus 2888: difference: -47.5%; mean 305.4 VS 160.4; p = 0.002) and structural (84 versus 17: difference: -79.8%; mean 4.7 Vs 0.9; p < 0.001) procedures decreased during CoV-time compared to NoCoV-time. In particular, coronary angiographies (1782 versus 3460), PCI (1074 versus 1983), p PCI (271 versus 410), TAVR (11 versus 72) and Mitraclip (6 versus 12) showed a reduction of 48.5%, 45.7%, 33.7%, 84.7% and 50.0%, respectively (all p for comparison <0.05). CONCLUSIONS: Compared to the same time-period in 2019, both coronary and structural interventional procedures during COVID-19 epidemic suffered a dramatic decrease in Piedmont, Italy. Organizational change and structured clinical pathways should be created, together with awareness campaigns.

OBJECTIVE: The follow-up patency rates and associated clinical and angiographic variables following stenting of very long (> or =50 mm) and chronic (>6 months) total coronary artery occlusive lesions are not well documented. The aim of the present study was to evaluate the early results and mid-term outcomes following angioplasty of such lesions. METHODS: Between January 2000 and June 2002, we treated 278 chronic coronary occlusions. Of these, eighty-nine occlusions (89 patients) were with lesions > or =50 mm long; these patients constituted the study population. RESULTS: Mean duration of occlusion was 7 +/- 2 months (range, 6-13 months). Procedural success was obtained in 81 patients. A total of 211 coronary stents (2.6 +/- 1.1 stents/patient) were implanted, and mean stent length was 59 +/- 9 mm. In 3 patients, TIMI flow 1-2 was observed after stent implantation. Thus, the angiographic success was considered to be 78/89 patients (87.6%). Periprocedural major adverse cardiac events occurred in 6 patients (6.7%). Clinical success was obtained in 74 patients (83%). During a 9.6 +/- 2 month follow-up, forty-three patients (55.1%) remained angina free, thirty-two (41%) had recurrence of angina, three patients (3.9%) had a new myocardial infarction and no deaths were reported. Target vessel revascularization was required in 34 patients (43.6%). Angiographic follow-up was obtained in 70 patients (90%) at a mean of 7.4 +/- 2 months. Restenosis was observed in 36 patients (51%), six of whom had reocclusion. A significant correlation was observed between the need for reintervention and stent length (R 0.52), residual stenosis (R 0.73) and diabetes mellitus (0.68). CONCLUSION: Although coronary artery stenting for very long (> or =50 mm) chronically occlusive lesions is feasible, safe and associated with a low incidence of periprocedural adverse clinical events, these complex and expensive procedures still have a high 6-month restenosis rate. These results might be significantly improved with the advent of drug-eluting stents.
