Project description:Coronary arteriovenous fistulas and coronary cameral fistulas are rare anomalies that involve the abnormal communication between a coronary artery and a venous structure, such as a coronary vein or a right-sided cardiac chamber. Iatrogenic coronary arteriovenous fistulas and coronary cameral fistulas can be uncommon complications of coronary artery angiography and intervention. Acquired coronary arteriovenous fistulas that develop during percutaneous coronary intervention of chronic total occlusions have been previously reported in the literature. However, a coronary arteriovenous fistula resulting from contrast injection into a chronically and totally occluded right coronary artery during diagnostic coronary angiography is very rare. We present a unique case of a contrast-induced iatrogenic right coronary dissection leading to a coronary arteriovenous fistula communicating to the right atrium through the middle cardiac vein.

Project description:BACKGROUND:Iatrogenic acute aortic dissection (AD) is an extremely rare but devastating complication during cardiac catheterization. It can be treated conservatively if it develops in a retrograde form or manifests as an intramural hematoma (IMH) with a micro-intimal tear in the absence of instability. However, only a few reports exist on its natural course and long-term outcomes. CASE PRESENTATION:A 78-year-old woman presented to the emergency department with acute chest discomfort. Elective cardiac catheterization was performed via the right radial artery. The patient's brachiocephalic artery was so tortuous that the hydrophilic soft guidewire had to be exchanged for a stiffer one. However, the stiff wire caused the dissection of a tortuous brachiocephalic artery that extended from the sinuses of Valsalva to the proximal descending aorta. Emergent computed tomography showed crescentic aortic wall thickening without a dissection flap. The patient had cardiac tamponade and a gradually thickening thrombosed false lumen. Although the patient was unstable during the first 2?weeks, she was stabilized during hospital stay with only conservative treatment. Consequently, she has been well for over 5?years. CONCLUSIONS:Even though the patient showed ominous findings, a good prognosis was expected because the AD was mainly retrograde. Furthermore, the thrombosed false lumen mimicked an IMH on imaging. To the best of our knowledge, this is the first report of an extensive iatrogenic AD originating from the brachiocephalic artery during right transradial catheterization that was treated conservatively despite clinical instability.

Project description:IntroductionCoronary artery dissections with or without rupture is a rare but well-recognized complication of coronary angiography with a high morbidity and mortality rate.Case presentationWe present a rare case of right coronary artery dissection distal to a totally occluded vessel. The vessel dissected during the second injection of contrast agent without any direct mechanical manipulation (catheter or guide-wire induced). Hopefully the dissection had no clinical consequences and the patient was discharged after 48 hour intensive monitoring.ConclusionsWe believe that the contrast agent that was forced in the proximal part of the RCA increased through the anastomotic branches the sheer stress on the diseased endothelium of the distal artery causing it to dissect. It is an instructive -not previously described- phenomenon that underscores that atherosclerotic tissue is unpredictable and should be treated with extreme caution.

Project description:To sythesize the available literature on hand dysfunction after transradial catheterization.We searched MEDLINE and EMBASE. The search results were reviewed by two independent judicators for studies that met the inclusion criteria and relevant reviews. We included studies that evaluated any transradial procedure and evaluated hand function outcomes post transradial procedure. There were no restrictions based on sample size. There was no restriction on method of assessing hand function which included disability, nerve damage, motor or sensory loss. There was no restriction based on language of study. Data was extracted, these results were narratively synthesized.Out of 555 total studies 13 studies were finally included in review. A total of 3815 participants with mean age of 62.5 years were included in this review. A variety of methods were used to assess sensory and motor dysfunction of hand. Out of 13 studies included, only 3 studies reported nerve damage with a combined incidence of 0.16%, 5 studies reported sensory loss, tingling and numbness with a pooled incidence of 1.52%. Pain after transradial access was the most common form of hand dysfunction (6.67%) reported in 3 studies. The incidence of hand dysfunction defined as disability, grip strength change, power loss or any other hand complication was incredibly low at 0.26%. Although radial artery occlusion was not our primary end point for this review, it was observed in 2.41% of the participants in total of five studies included.Hand dysfunction may occur post transradial catheterisation and majority of symptoms resolve without any clinical sequel.

Project description:Iatrogenic coronary artery dissection is a potentially life-threatening complication of cardiovascular interventions. The optimal management of iatrogenic coronary artery dissection is not clear; however, both conservative management and percutaneous or surgical revascularization have been performed depending on the patient's clinical status and the extent of dissection. We present the first reported case of right coronary artery dissection after Bentall procedure performed for ascending aortic aneurysm. Urgent percutaneous intervention using adjunctive coronary imaging was performed with excellent clinical recovery. In this article, we highlight coronary artery dissection after Bentall procedure as a possible complication, provide an insight into various options in its management, and review published data on iatrogenic coronary artery dissection. We also discuss the challenges in percutaneous treatment of coronary artery dissection with special focus on intracoronary imaging for accurate diagnosis and guidance in the management of this complex lesion.

Project description:Iatrogenic aortocoronary dissection (IACD) occurs mainly during procedures involving the right coronary artery (RCA) and can result in disabilities, the need for urgent complex surgery, and even death. The risk factors for IACD are ill characterized, and the best management strategy is questionable; thus, there is a need to evaluate the characteristics, treatment options, and outcomes of patients with IACD of the RCA. We searched medical databases for publications on IACD of the RCA to present the characteristics of the procedures, management, and outcomes. We report 142 cases of IACD of the RCA, reported between 1973 and 2021. The mean age of the patients was 63.0 years, 81 (57%) were men, 75 (52.8%) presented with stable angina, and 29 (20.4%) had chronic total occlusion of the RCA. The most used catheter shapes were Judkins right (42%) and Amplatz left (25%), and most (56%) catheters were used during percutaneous coronary interventions. Guiding catheters were used in 38% (19/50) of diagnostic procedures when IACD occurred. A catheter size of ≤5F was used in only 3 cases. The catheter size was 6F in 22% of the cases, >6F in 23%, and not reported in 52%. A high-grade dissection (Dunning class III) occurred in 54% (77/142) of the cases. Stenting of the RCA ostium was performed in 88 (62%) of the cases, conservative treatment in 25 (18%), and surgery in 40 (28%) (aortic root repair [5%], coronary artery bypass grafting and aortic root repair [11%], and coronary artery bypass grafting alone [10%]). The mortality rate was 6.5% (5/77) among patients with class III dissection. Each patient should be considered independently. The most frequent intervention was to seal the dissection with a stent in the ostial RCA. However, in select cases published in the literature, a conservative approach was a feasible and successful option.

Project description:This is the case of a 40-year-old female diagnosed with NSTEMI. She underwent coronary angiography and suffered from type F left main coronary artery dissection. After hemodynamic stabilization, she was transferred to the nearest cardiothoracic surgery unit and underwent emergency coronary artery bypass graft (CABG) surgery. This report highlights important concepts in the management of a rare complication and emphasizes the surgical treatment decision-making, underlying an unusual but effective treatment approach.

Project description:Although rare, right coronary artery (RCA) injury is a serious complication of tricuspid annuloplasty (TAP) and warrants close attention. We report a case of ST elevation myocardial infarction secondary to iatrogenic RCA occlusion during minimally invasive cardiac surgery (MICS). Electrocardiography (ECG) revealed ST segment elevation in lead II. Transesophageal echocardiography (TEE) revealed inferior wall hypokinesis after cardiopulmonary bypass, and coronary angiography revealed peripheral RCA occlusion. Intraoperatively, we detected an atrioventricular groove deformity during the second surgical procedure. Wall motion and ECG abnormalities showed normalization after TAP was reestablished. Vigilant monitoring using TEE and ECG is important to detect intraoperative myocardial ischemia during MICS-TAP.

Project description:Iatrogenic acute dissection of ascending aorta following coronary angiography and percutaneous intervention is a rare complication. Most reports involve localized aortic dissections as a complication of cannulation of a coronary artery with propagation into the ascending aorta. It is usually treated by sealing the intima with a stent in the ostium of the coronary artery or conservative management, while extensive dissections may require a surgical intervention. We describe a case of the subclavian dissection extending into the ascending aorta that occurred during diagnostic catheterization using the radial approach. The patient was successfully treated utilizing conservative management.

Project description:BackgroundCardiac catheterization may cause retinal embolization, a risk factor for cerebrovascular emboli and stroke. We describe the incidence of clinically silent and apparent retinal emboli following diagnostic and interventional coronary catheterization and associated risk factors.MethodsThree hundred selected patients attending a tertiary referral center for diagnostic and therapeutic cardiac catheterization were studied. Retinal examination and examination of the visual field and acuity were done before and after catheterization by a retinal specialist.ResultsThere were 5 case of retinal embolus before catheterization, and 19 patients (incidence 6.3%) developed new retinal arteriolar emboli after catheterization. Only 1 patient developed clinically apparent changes in vision. Two conventional risk factors (age and hypertension) were significantly associated with new retinal emboli. The risk of retinal emboli was also significantly associated with operator expertise.ConclusionsRetinal embolism was found after coronary catheterization in 6.3% of our patients. This finding indicates that the retinal, and possibly the cerebral circulation, may be compromised more frequently than is clinically apparent as a complication of coronary catheterization. Age and hypertension are independent predictors of retinal embolism.
