This can result in elevated blood pressure, increased heart rate, and vasoconstriction. A 67-year-old Black male was admitted to the emergency department with a chief complaint of shortness of breath for 2 days. On examination, he exhibited edema and symmetric palpable pulses in his lower limbs. His electrocardiogram revealed left axis deviation, sinus tachycardia, and ST-segment elevation. Reverse transcription-polymerase chain reaction confirmed COVID-19. Hydralazine (5 mg) was administered intravenously immediately. The patient was re-evaluated after 20 min during his stay in the emergency department. After two 5 mg doses of hydralazine, he developed reflex tachycardia. To control heart rate, IV hydralazine was replaced with oral atenolol (50 mg once daily), a β₁-blocker that reduces cardiac output. Subcutaneous enoxaparin 80 mg daily was given to prevent thrombotic complications in hospitalized COVID-19 patients. Acute hypertension and COVID-19-induced hypertensive emergencies in patients with preexisting hypertension are typically associated with a worse prognosis.","PeriodicalId":51760,"journal":{"name":"Case Reports in Cardiology","volume":"2026 ","pages":"9408438"},"PeriodicalIF":0.5,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13147342/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147846014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case demonstrates successful reperfusion using a flexible, hydrophilic-coated guide catheter extension (GuidePlus, Nipro, Osaka, Japan).Methods: A 45-year-old man with inferior STEMI had complete occlusion of a severely ectatic (6.5 mm, 1.8× reference) and tortuous RCA with a 'shepherd's crook' morphology. The conventional GuideLiner failed to cross. GuidePlus, a soft and hydrophilic extension, enabled thrombus aspiration and intracoronary urokinase (240,000 IU) delivery. A 4.0 × 28-mm drug-eluting stent (Ultimaster, Terumo) was deployed and postdilated (5.0-mm NC balloon).Results: The GuidePlus enabled smooth navigation, direct aspiration and thrombolysis. Final angiography confirmed TIMI Grade 3 flow with minimal residual thrombus. The patient was discharged uneventfully and has remained event-free with dual antiplatelet therapy (aspirin and prasugrel).Conclusion: GuidePlus offers excellent flexibility and crossability for managing STEMI in ectatic and tortuous arteries when conventional devices fail.","PeriodicalId":51760,"journal":{"name":"Case Reports in Cardiology","volume":"2026 ","pages":"5644505"},"PeriodicalIF":0.5,"publicationDate":"2026-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13090674/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147724559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using reversed (mirror-image) precordial lead placement, high-definition 3D electroanatomic mapping, and intracardiac echocardiography, successful radiofrequency ablation was achieved using a completely zero-fluoroscopy approach.Discussion: In patients with congenital cardiac anomalies, the applicability of zero-fluoroscopy strategies is often limited because of their complex anatomy. Successful management requires in-depth anatomical understanding and carefully adapted procedural techniques. This case highlights that even in the setting of significant anatomical variation, a systematic zero-fluoroscopy approach can lead to effective and safe outcomes.Take‐home message: Zero-fluoroscopy PVC radiofrequency ablation using high-definition 3D mapping and intracardiac echocardiography is a feasible and safe approach, even in anatomically challenging cases such as situs inversus.","PeriodicalId":51760,"journal":{"name":"Case Reports in Cardiology","volume":"2026 ","pages":"1241820"},"PeriodicalIF":0.5,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13080684/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147700855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a rare case of a 57-year-old male who presented with classical symptoms of inferior ST-segment elevation myocardial infarction (STEMI). Initial coronary angiography failed to identify the right coronary artery (RCA), eventually revealing an absent RCA ostium. The superdominant left circumflex artery (LCX) was found to be entirely occluded, supplying the territory typically serviced by the absent RCA. Successful primary percutaneous coronary intervention (PCI) was performed using a drug-eluting stent (DES), restoring TIMI-III flow and resolving symptoms promptly. Further imaging with contrast-enhanced computed tomography coronary angiography (CTCA) confirmed the congenital absence of the RCA, emphasising the critical role of advanced imaging in diagnosing coronary anomalies. Our case underscores the importance of considering rare congenital anomalies in acute cardiac presentations. It highlights the pivotal role of rapid recognition, targeted imaging and intervention in such anomalies to ensure optimal patient outcomes. It advocates a multidisciplinary approach, integrating cardiologists, radiologists and interventional specialists to enhance clinical decision-making and management effectiveness in similar complex scenarios.","PeriodicalId":51760,"journal":{"name":"Case Reports in Cardiology","volume":"2026 ","pages":"8887458"},"PeriodicalIF":0.5,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13062653/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147678432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
