Total Percutaneous Transfemoral Endovascular Treatment of Non-A Non-B Aortic Dissection.

Although open repair remains the mainstream treatment for aortic arch dissection, its surgical complexity and perioperative complications are significant. We developed a novel stentgraft system for less-invasive endovascular aortic arch repair. We successfully performed a total percutaneous transfemoral endovascular repair of aortic arch dissection using a novel off-the-shelf endograft system.

Left Atrial Papillary Fibroelastoma Mimicking Myxoma.

Papillary fibroelastomas (PFEs) followed by cardiac myxomas (CM) are the 2 most common primary benign cardiac tumors. Although typically asymptomatic, they can manifest with nonspecific symptoms such as dyspnea and dizziness or more acute manifestations such as embolic events. We describe an unusual location of a PFE typically seen with a CM.

Surgical Management of Fibrosing Mediastinitis Presenting as Superior Vena Cava Syndrome.

Fibrosing mediastinitis is a rare chronic inflammatory condition characterized by excessive fibrotic process in the mediastinum. Although various infectious processes are more common causes, it can also be related to several malignancies. We report a case of a 28-year-old woman with fibrosing mediastinitis related to an aggressive primary gray-zone lymphoma causing complete occlusion of the superior vena cava (SVC) and the innominate veins.

Oncologic Brugada.

Structural abnormalities within the right ventricular outflow tract (RVOT) can present similarly to Brugada syndrome. A 34-year-old woman with no medical history presented with polymorphic ventricular tachycardia/ventricular fibrillation cardiac arrest and initial electrocardiogram showed type I Brugada pattern. Cardiac magnetic resonance imaging revealed prominent tissue thickening at the RVOT with late gadolinium enhancement.

Regrowth Rate of a Cardiac Myxoma After Percutaneous Aspiration.

Cardiac myxomas are typically treated surgically; however, the operative mortality and recurrence rates are not negligible. In the current report we describe a case of repeat percutaneous aspiration of a right atrial myxoma. The report supports feasibility of the procedure, provides the asymptomatic timeframe after debulking, and the regrowth rate.

Novel Use of a Catheter-Based Device Retrieval System for Percutaneous Treatment of Recurrent Atrial Myxoma.

Surgical resection is standard of care for the treatment of atrial myxoma. However, the optimal management strategy for recurrent cardiac tumors is less clear. Here we report the novel use of a catheter-based device retrieval system for the removal of a recurrent cardiac myxoma.

The DIMASHQ Procedure: AO Plug pseudoaneurys repair in cending aorta using uality intracardiac ecocardiography.

The transcatheter management of complex cardiovascular diseases has significantly evolved, offering less invasive alternatives to traditional surgical interventions. In this report we describe 2 cases of patients who developed ascending aortic pseudoaneurysms soon after coronary artery bypass grafting. With meticulous computed tomography angiography planning and with live intracardiac echography, these patients underwent successful transcatheter repair using a 6/4-mm Amplatzer Duct Occluder II (Abbott) vascular plug.

A Severely Calcified, Undilatable, Coronary Artery Stenosis: Impact of Serial Lithotripsy on Calcium Fracture and Lumen Expansion.

Percutaneous coronary intervention of a severely calcified coronary artery stenosis is associated with stent underexpansion and adverse outcomes. Intravascular lithotripsy (IVL) is a novel technology for fracturing calcified plaque in the coronary artery. We describe the first case of a severely calcified, undilatable coronary artery lesion.

Indirect Ballistic Injury Resulting in Non-ST-Segment Elevation Myocardial Infarction.

Gunshot-related myocardial injuries typically result from direct penetrating injury by the traversing bullet. We present a case of gunshot-related myocardial injury in the absence of direct penetrating injury to the cardiac structures and describe alternative mechanisms for ballistic-induced injury.

Extracavitary Cardiac Calcific Amorphous Tumors Compressing Biventricular Outflow Tracts.

Extracavitary cardiac calcific amorphous tumors/masses are extremely rare. We present a case report of a 62-year-old man with end-stage renal disease who presented with extracavitary cardiac calcific amorphous tumors/masses compressing the biventricular outflow tracts, resulting in hemodynamic compromise and progressive limitation of activities. The patient was successfully treated with surgery, with complete resolution of symptoms and markedly improved quality of life.

Intracardiac Teratoma in a Patient With Nonseminomatous Germ Cell Tumor.

This case report describes the management of a 30-year-old male patient with a history of an advanced nonseminomatous germ cell tumor, hip fracture complicated by extensive deep vein thrombosis and pulmonary embolism, and on apixaban presenting with asymptomatic intracardiac teratoma and abdominopelvic metastases. Multidisciplinary intervention, including successful surgical excision of the intracardiac mass, highlights the importance of coordinated care and vigilant follow-up in optimizing patient outcomes and preventing life-threatening complications.

Tongue Squamous Cell Carcinoma With Cardiac Metastases.

A 60-year-old man with squamous cell carcinoma of the tongue had atypical chest pain and mild troponin elevation. No significant electrocardiogram changes or arrhythmias were noted. Cardiac magnetic resonance revealed several myocardial metastases with pericardial involvement, confirmed by positron emission tomography/computed tomography.

Obstructive Thrombosis of Transcatheter Pulmonary Valve-in-Valve Prosthesis.

A 79-year-old woman, previously treated for congenital pulmonary valve stenosis through surgical and transcatheter procedures, presented with worsening dyspnea. This led to the identification of valve thrombosis in her bioprosthetic pulmonary valve. This report delves into the clinical importance of obstructive valve thrombosis, its diagnostic assessment, and potential therapeutic strategies.

Clinical Presentation and Percutaneous Treatment of Hemolytic Anemia Associated With Paravalvular Leak After TAVR.

Paravalvular leak (PVL) following transcatheter aortic valve replacement (TAVR) is an established complication, albeit rarely associated with hemolytic anemia. This report details 3 cases of significant hemolytic anemia attributed to TAVR-induced PVL, each with distinct clinical presentations and manifestations. These cases underscore the diverse and occasionally subtle clinical presentation of aortic PVL-associated hemolytic anemia.

Unveiling Cardiac Mysteries: The Role of Endomyocardial Biopsy in Diagnosing Heart Masses.

This case series highlights the role of endomyocardial biopsy (EMB) in diagnosing cardiac tumors instead of tumor resection. EMB provided critical diagnostic clarity and influenced therapeutic decisions, demonstrating its utility in complex cardiovascular cases while preventing unnecessary surgery. Furthermore, EMB provides vital information that can be used for a multidisciplinary approach to cardiac tumors.

Critical Acute Left Ventricular Outflow Tract Obstruction Due to Cardiac Sarcoma.

Left ventricular outflow tract (LVOT) obstruction is mostly caused by hypertrophic obstructive cardiomyopathy and subaortic stenosis. Rarely, malignancy can lead to dynamic LVOT obstruction and has only been sporadically documented. We present the first case of dynamic and/or nearly fixed LVOT obstruction caused by a cardiac myxoid spindle cell sarcoma.

TEER for SAM of the Mitral Valve and Flail Posterior Mitral Leaflet: 1-Clip Solution.

Transcatheter edge-to-edge repair (TEER) is approved for patients with symptomatic severe mitral regurgitation (MR) who are deemed inoperable or at high surgical risk with life expectancy of more than 1 year, but has also been used off-label in patients with hypertrophic obstructive cardiomyopathy (HOCM) for symptomatic relief who are not candidates for septal reduction therapy. An 83-year-old woman with decompensated heart failure was found to have HOCM with systolic anterior motion of the mitral valve and a large P2 flail segment with ruptured cords. TEER was performed resulting in mild MR and resolution of the prior left ventricular outflow tract gradient.

Transcatheter Aortic Valve Replacement in Patients With Interventricular Membranous Septal Aneurysms.

Aneurysms of the interventricular membranous septum are a rare anatomical feature that can be detected incidentally on computed tomography or echocardiography. Such aneurysms can pose challenges in the treatment of patients with aortic valve stenosis. A case series of 2 patients with membranous septal aneurysms treated successfully with current-generation balloon-expandable and self-expanding transcatheter heart valves is presented here.

An Acellular Platform to Drive Urinary Bladder Tissue Regeneration.

Impaired bladder compliance secondary to congenital or acquired bladder dysfunction can lead to irreversible kidney damage. This is managed with surgical augmentation utilizing intestinal tissue, which can cause stone formation, infections, and malignant transformation. Co-seeded bone marrow mesenchymal stem cell (MSC)/CD34+ hematopoietic stem cell (HSPC) scaffolds (PRS) have been successful in regenerating bladder tissue.
