Project description:BackgroundUnderexpanded stent in heavily calcified coronary lesion is common and persists over years. It is related to long-term failure and negative outcomes. Treatment of this situation after many years with intracoronary lithotripsy (ICL-Shockwave®) could be an option.Case summaryWe report a case of a man with underexpanded coronary stent implanted 11 years earlier. Optical coherence tomography highlighted the mechanism of stent underexpansion showing the presence of calcium stones under the old struts. Intracoronary lithotripsy crushed calcium under the stent struts causing its geometric change (from elliptical to round shape) and a consequent better transmission of the true radial force of the old stent.DiscussionHeavily calcified coronary lesions lead to stent underexpansion which persists over years. Intracoronary lithotripsy could be a very late option to manage this unfavourable common result.

Project description:Given the limited salvage options for in-stent restenosis (ISR) of drug-eluting stents (DES), our high-volume cardiac catheterization laboratory has been performing intracoronary brachytherapy (ICBT) in patients with recurrent ISR of DES. This study analyzes their baseline characteristics and assesses the safety/toxicity of ICBT in this high-risk population.A retrospective analysis of patients treated with ICBT between September 2012 and December 2014 was performed. Patients with ISR twice in a single location were eligible. Procedural complications included vessel dissection, perforation, tamponade, slow/absent blood flow, and vessel closure. Postprocedural events included myocardial infarction, coronary artery bypass graft, congestive heart failure, stroke, bleeding, thrombosis, embolism, dissection, dialysis, or death occurring within 72 hours. A control group of patients with 2 episodes of ISR at 1 location who underwent percutaneous coronary intervention without ICBT was identified. Unpaired t tests and χ2 tests were used to compare the groups.There were 134 (78%) patients in the ICBT group with 141 treated lesions and 37 (22%) patients in the control group. There was a high prevalence of hyperlipidemia (>95%), hypertension (>95%), and diabetes (>50%) in both groups. The groups were well-balanced with respect to age, sex, and pre-existing medical conditions, with the exception of previous coronary artery bypass graft being more common the ICBT group. Procedural complication rates were low in the control and ICBT groups (0% vs 4.5%, P = .190). Postprocedural event rates were low (<5%) in both groups. Readmission rate at 30 days was 3.7% in the ICBT group and 5.4% in the control group (P = .649).This is the largest recent known series looking at ICBT for recurrent ISR of DES. ICBT is a safe treatment option with similarly low rates (<5%) of procedural and postprocedural complications compared with percutaneous coronary intervention alone. This study establishes the safety of ICBT in a high-risk patient cohort.

Project description:BackgroundIn-stent restenosis is a difficult percutaneous scenario if calcific neoatherosclerosis is the underlying aetiology.Case summaryA 69-year-old diabetic woman with a previous percutaneous coronary intervention on the left anterior descending coronary artery was readmitted for non-ST-elevation myocardial infarction. In-stent restenosis due to calcific neoatherosclerosis was observed by intracoronary imaging during the intervention. Intravascular lithotripsy was used successfully to fracture the underlying calcific plaque. However, the balloon ruptured during treatment although this did not damage the artery.DiscussionIntravascular lithotripsy is a promising tool for the treatment of extremely calcified lesions including calcific neoatherosclerosis of in-stent restenosis. Balloon rupture is a complication of this new percutaneous treatment that has not previously been described.

Project description:Percutaneous coronary intervention was performed in a flush in-stent right coronary artery chronic total occlusion. Successful retrograde recanalization was performed but the lesion was balloon undilatable as confirmed by intravascular ultrasound. High-pressure post-dilation with noncompliant and plaque modification balloons failed, but intravascular lithotripsy successfully expanded the lesion. (Level of Difficulty: Advanced.).

Project description:BACKGROUND:Permanent cardiac pacemakers require invasive procedures with complications often related to long pacemaker leads. We are developing a percutaneous pacemaker for implantation of an entire pacing system into the pericardial space. METHODS:Percutaneous micropacemaker implantations were performed in 6 pigs (27.4-34.1 kg) using subxyphoid access to the pericardial space. Modifications in the implantation methods and hardware were made after each experiment as the insertion method was optimized. In the first 5 animals, nonfunctional pacemaker devices were studied. In the final animal, a functional pacemaker was implanted. RESULTS:Successful placement of the entire nonfunctional pacing system into the pericardial space was demonstrated in 2 of the first 5 animals, and successful implantation and capture was achieved using a functional system in the last animal. A sheath was developed that allows retractable features to secure positioning within the pericardial space. In addition, a miniaturized camera with fiberoptic illumination allowed visualization of the implantation site before electrode insertion into myocardium. All animals studied during follow-up survived without symptoms after the initial postoperative period. CONCLUSIONS:A novel micropacemaker system allows cardiac pacing without entering the vascular space or surgical exposure of the heart. This pericardial pacemaker system may be an option for a large number of patients currently requiring transvenous pacemakers but is particularly relevant for patients with restricted vascular access, young children, or those with congenital heart disease who require epicardial access.

Project description:A 54-year old, hypertensive female patient underwent percutaneous coronary angioplasty (PTCA) followed by stenting of calcified chronic totally occluded right coronary artery. The post dilation balloon catheter got stuck and snapped during manipulations in inflated position within the stent, which could not be retrieved by nonsurgical interventions. Emergency surgery was performed to retrieve the stent along with an inflated balloon, followed by vein patch closure of arteriotomy and reversed saphenous vein graft anastomosis to right coronary artery and left anterior descending artery on cardiopulmonary bypass.

Project description:IntroductionPrimary malignant pericardial mesothelioma is a very rare pericardial tumor of unknown etiology.Case presentationA 61-year-old Caucasian woman was admitted to our hospital complaining of exertional dyspnea due to a large pericardial effusion. Intrapericardial fluid volume declined after repeated pericardiocentesis, but the patient progressively developed a hemodynamically relevant pericardial constriction. Pericardiectomy revealed a pericardial mesothelioma. Subsequently, four cycles of chemotherapy (dosage according to recently published trials) were administered. The patient remained asymptomatic, and there was no recurrence of the tumor after three years.ConclusionPericardial mesothelioma should be considered and managed appropriately in non-responders to pericardiocentesis, and in patients who develop constrictive pericarditis late in their clinical course.

Project description:Angioedema can cause potentially life-threatening airway obstruction. This case report describes an exceedingly rare episode of ticagrelor-induced hypersensitivity reaction, manifesting as angioedema with periorbital and likely respiratory involvement. The heart team should be vigilant for this precarious condition which may require emergent airway management. Desensitization protocols and alternative regimens (e.g., clopidogrel, prasugrel, and addition of an adjunctive anticoagulant) should be considered when there is an absolute indication for antiplatelet therapy.
