Percutaneous coronary interventions in patients with transplanted heart coronary artery disease. Effects of intracoronary stent implantation on long-term results

BACKGROUND: Transplanted heart coronary artery disease (TxCAD) is the most frequent casue of death occuring > or =5 years after orthotopic heart transplantation (OHT). Considering three basic therapeutic approaches - percutaneous coronary intervention (PCI), surgical revascularisation and retransplantation - PCI seems to be the superior method due to its safety and good short-term results, however, the long-term efficacy of PCI has been less well established. AIM: To evaluate long-term results of PCI in the treatment of OHT recipients with TxCAD. METHODS: The study group consisted of 20 patients (19 males, aged 24-63, median 45.5 years; 14 (70%) had before OHT), who underwent single or multiple PCI of significant coronary lesions, revealed by elective (n=17) or urgent (n=3) coronary angiography (CAG). The overall number of PCI procedures was 26, including 8 with stent implantation. procedures were performed 9-151 (median 61.5) months after OHT. Analysis of PCI results was based on the follow-up CAGs or autopsy in case of death. RESULTS: Follow-up time was 3-90 (median 28) months. At least one CAG was performed in 17 (85%) patients - the overall number of follow-up CAGs was 53. Progression of TxCAD was revealed by 33 (62%) CAGs - the decision to perform subsequent single or multiple PCI was undertaken in 22 (42%) patients. The overall number of re-PCI procedures was 38 (with stent implantation in 11 cases). Out of 38 PCI procedures without stent implantation, significant restenosis was found on control CAG in 16 (42%) patients, and out of 16 PCI with stents -- in 11 (69%) patients, including 8 haemodynamically significant lesions. TxCAD was the cause of 5 out of 9 deaths that occurred during follow-up. CONCLUSIONS: PCI is unable to stop TxCAD development in the majority of patients. Stent implantation does not improve long-term results of TxCAD treatment.

Long-term outcomes after percutaneous coronary intervention of left main coronary artery for treatment of cardiac allograft vasculopathy after orthotopic heart transplantation

The present study evaluated the safety and efficacy of percutaneous coronary intervention (PCI) of the unprotected left main coronary artery (ULMCA) for the treatment of cardiac allograft vasculopathy (CAV) in consecutive unselected patients with orthotopic heart transplantation (OHT). PCI in patients with OHT and develop CAV has been associated with greater restenosis rates compared to PCI in patients with native coronary artery disease. A paucity of short- and long-term data is available from patients with OHT who have undergone PCI for ULMCA disease. The present retrospective, multicenter, international registry included 21 patients with OHT and CAV who underwent ULMCA PCI from 1997 to 2009. Angiographic success was achieved in all patients. Drug-eluting stents were used in 14 of the 21 patients. No major adverse cardiac events or repeat OHT occurred within the first 30 days. At a mean follow-up of 4.9 ± 3.2 years, 3 patients (14%) had died, myocardial infarction had occurred in 1 patient (5%), and target lesion revascularization had been required in 4 patients (19%). Follow-up angiography was performed in 16 patients (76%), and restenosis was observed in 4 (19%). No stent thrombosis of the ULMCA was observed. One patient (5%) underwent coronary artery bypass grafting, and 5 patients (24%) underwent repeat OHT. In conclusion, the results of our study have shown ULMCA PCI to be safe and reasonably effective in patients with OHT and represents a viable treatment strategy for CAV in these patients.     

Percutaneous coronary intervention in patients with essential thrombocythemia: case reports and literature review

Abstract

Essential thrombocythemia (ET) can cause systemic vascular thrombosis, but the involvement of coronary arteries is rare. This study is aimed to analyze the characteristics, treatment, and prognosis during follow-up in patients with ET after percutaneous coronary intervention (PCI). A total of eight patients with ET who had coronary heart disease and treated with PCI in our hospital from 2012 to 2018 were retrospectively studied. The basic clinical information with clinical data, data of coronary intervention, application of anti-platelet and platelet reducing drugs, and the results of long-term follow-up were recorded. There were five males and three females with a median age of 67 years. Clinical presentation was unstable angina in four cases, stable angina in one case, ST-elevation myocardial infarction in two cases, and non-ST elevation myocardial infarction in one case. The average platelet count was 722 × 10⁹/L in admission, and hydroxyurea was used in seven cases. Coronary angiography suggested that all eight cases were single-vessel lesion. All the patients received PCI treatment, and Drug-eluting stent (DES) was used in all cases. Six were treated with one stent, one was treated with two stents and one was treated with three stents. After PCI, aspirin, and clopidogrel (or ticagrelor) were used in all cases. During the follow-up, one developed stent thrombus 2 months later, two developed stent restenosis 1 year later. In conclusion, PCI is an effective method of revascularization in patients with ET; but it may be associated with a higher rate of complications including stent thrombus and restenosis.

Clinical and angiographical follow-up after implantation of a 6--12 microCi radioactive stent in patients with coronary artery disease.

AIMS: This study is the contribution by the Thoraxcenter, Rotterdam, to the European(32)P Dose Response Trial, a non-randomized multicentre trial to evaluate the safety and efficacy of the radioactive Isostent in patients with single coronary artery disease. METHODS AND RESULTS: The radioactivity of the stent at implantation was 6--12 microCi. All patients received aspirin indefinitely and either ticlopidine or clopidogrel for 3 months. Quantitative coronary angiography measurements of both the stent area and the target lesion (stent area and up to 5 mm proximal and distal to the stent edges) were performed pre- and post-procedure and at the 5-month follow-up. Forty-two radioactive stents were implanted in 40 patients. Treated vessels were the left anterior descending coronary artery (n=20), right coronary artery (n=10) or left circumflex artery (n=10). Eight patients received additional non-radioactive stents. Lesion length measured 10+/-3 mm with a reference diameter of 3.07+/-0.69 mm. Minimal lumen diameter increased from 0.98+/-0.53 mm pre-procedure to 2.29+/-0.52 mm (target lesion) and 2.57+/-0.44 mm (stent area) post-procedure. There was one procedural non-Q wave myocardial infarction, due to transient thrombotic closure. Thirty-six patients returned for angiographical follow-up. Two patients had a total occlusion proximal to the radioactive stent. Of the patent vessels, none had in-stent restenosis. Edge restenosis was observed in 44%, occurring predominantly at the proximal edge. Target lesion revascularization was performed in 10 patients and target vessel revascularization in one patient. No additional clinical end-points occurred during follow-up. The minimal lumen diameter at follow-up averaged 1.66+/-0.71 mm (target lesion) and 2.12+/-0.72 (stent area); therefore late loss was 0.63+/-0.69 (target lesion) and 0.46+/-0.76 (stent area), resulting in a late loss index of 0.65+/-1.15 (target lesion) and 0.30+/-0.53 (stent area). CONCLUSION: These results indicate that the use of radioactive stents is safe and feasible, however, the high incidence of edge restenosis makes this technique currently clinically non-applicable.
