The increased use of radiofrequency ablation (RFA) for atrial fibrillation (AF) has led to a rise in cases of pulmonary vein stenosis or occlusion (PVS/O) as a complication. The actual frequency of pulmonary vein (PV) occlusion remains a topic of debate.
BackgroundPulmonary vein stenosis in children is associated with a poor prognosis. However, the cause and risk factors for mortality remain uncertain.MethodsThis retrospective, singlecenter study identified children with primary and secondary pulmonary vein stenosis through a cardiac catheterization database. 95% CI, 2.214.1];P<0.001).
However, the most recurrent cardiac complication in RASopathies is pulmonary valve stenosis (PVS). This has motivated compassionate use of MEK inhibition (MEKi) for rare, but potentially lethal complications such as hypertrophic cardiomyopathy and lymphatic disease.

Intubated and given nitric oxide for pulmonary hypertension. Four- week echo continues to show pulmonic valve stenosis. Patient scheduled for a balloon valvuloplasty. Unlike adult hearts, the right ventricle comparatively large due to the work it has to do to pump against the high pulmonary pressure before birth.
BackgroundRecurrent pulmonary vein stenosis (PVS) following surgical repair of total anomalous pulmonary venous connection is associated with poor prognosis. Journal of the American Heart Association, Volume 14, Issue 4 , February 18, 2025.
Such a pattern is consistent with significant left main coronary artery stenosis. Clinical evaluation and X-Ray chest showed features of pulmonary edema. Angiography done after initial stabilization showed severe stenosis of distal left main coronary artery. ST segment elevation is noted in aVR.
In this week’s View, Dr. Eagle looks at the durability of pulmonary vein isolation using pulsed-field ablation, then examines genetic penetrance of dilated cardiomyopathy in genotype-positive relatives.
Cryoablation for atrial fibrillation is a widely used technique for pulmonary vein isolation. Known complications associated with cryoablation include tamponade, phrenic nerve injury, stroke, pulmonary embolism, pulmonary vein stenosis, and atrioesophageal fistulas.
BackgroundRING finger protein 213 (RNF213) p.R4810K is an established risk factor for moyamoya disease and intracranial artery stenosis in East Asian people. Recent evidence suggests its potential association with extracranial cardiovascular diseases, including pulmonary hypertension. All patients had cerebrovascular diseases.
Transcatheter pulmonary valve replacement (TPVR) has become a safe and effective alternative to surgical PVR in tetralogy of Fallot (TOF), isolated pulmonarystenosis (PS), and other congenital heart disease (CHD) variants.
The CXR demonstrated no pulmonary edema. The LM has an irregular 30% distal stenosis, followed by an 80% ostial LAD stenosis, and total occlusion of the LAD proximally with TIMI grade 1 flow in the distal vessel. The LCX demonstrates an ostial 80% stenosis prior to the bifurcation of a large OM artery. Type II ischemia.
Objective A novel artificial intelligence-based phenotyping approach to stratify patients with severe aortic stenosis (AS) prior to transcatheter aortic valve replacement (TAVR) has been proposed, based on echocardiographic and haemodynamic data. ±15.8 ±15.1 mm Hg, p value: 0.0079).
Voltage mapping was performed before and after PFA operation to help us detect the change in the electrical voltage of the pulmonary veins (PV). 3-Dimensional mapping system showed continuous low potential in the ablation site, and pulmonary vein isolation (PVI) was achieved in all four PV of the patients.
Both atria develop from a combination of the primitive atrium, sinus venous, and pulmonary veins.It Regarding the issue at hand, it is widely known that in cases of mitral stenosis with AF, the left atrium (LA) is larger than the right atrium (RA) due to the obvious reason that the baseline LA was larger at the onset of AF.
Pulmonary hypertension (PH) is a complex and progressive disorder characterised by elevated pulmonary artery pressure. Transcatheter aortic valve implantation (TAVI) is a minimally invasive surgical procedure that has revolutionised the treatment of severe aortic stenosis (AS).
Early management of this condition is typically dictated by the degree of pulmonarystenosis (PS) and resulting oxygen saturations. Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease (CHD).
ABSTRACT Introduction Pulmonary vein (PV) restenosis develops with reported incidence rates of up to 50%. The stenosis was treated with a stent. Balloon angioplasty seems to be the widely preferred treatment of choice. years later he presented with an in-stent restenosis that was successfully treated with a stent-in-stent strategy.
SCAPE is an acronym for sympathetic crash acute pulmonary edema, which can typcially occur in Pickering syndrome with renal artery stenosis [1]. Another term for transient acute pulmonary edema which occurs in renal artery stenosis is flash pulmonary edema. Sympathetic crashing acute pulmonary edem a.
The VARIPULSE Platform is designed to enable pulmonary vein isolation with the versatility of a catheter loop, a simple generator user interface, and a mapping system that provides an intuitive, reproducible workflow with real-time visualization, contact indicator, and PF tagging mechanisms.
At 3 and 6 months after ablation in patients with paroxysmal and non-paroxysmal AF, researchers did not observe any reported deaths or certain serious complications, including coronary spasm, persistent phrenic nerve palsy, atrio-esophageal fistula, or pulmonary vein stenosis. Lucas Boersma , electrophysiologist, St.

One is ventricular septal defect, second is overriding aorta, third is pulmonarystenosis, usually right ventricular outflow tract stenosis and associated right ventricular hypertrophy. Pulmonarystenosis, which is usually right ventricular outflow tract stenosis. As the name implies, there are four defects.
Assessment of fluid overload identifies aortic stenosis (AS) patients at high risk and treatment of fluid overload may potentially improve the post-interventional clinical course. Aims Cardiac decompensation in aortic stenosis (AS) involves extra-valvular cardiac damage and progressive fluid overload (FO). L = euvolaemia).
This report delineates two instances of AAV with large arterial involvement, one case presenting with lesions of the aortic valve and the other with lesions of the pulmonary artery. The first case involved a 57-year-old man with no underlying diseases.
That is, right ventricle is connecting to aorta, and left ventricle to pulmonary artery. That is, pulmonary artery is transposed over to the right ventricle, and aorta over to the left ventricle, so that normal anatomy is restored. In dextro transposition of great arteries or D-TGA, there is ventriculoarterial discordance.
Clinical introduction A woman in her 30s, a case of rheumatic mitral stenosis status post balloon mitral valvuloplasty 15 years prior, presented to urgent care with palpitations and dyspnoea for 1 week. Echocardiography demonstrated severe calcific mitral stenosis with pulmonary hypertension.
Animal studies have shown that mice with TBX1 gene mutations have smaller left pulmonary arteries compared to wild type mice, defined by a reduced left pulmonary artery (LPA) to right pulmonary artery (RPA) ratio. A single study has shown this translates to humans with 22q11 and structurally normal hearts.
The desired ultimate ability for such devices to treat a vascular stenosis without long-term device-related complications or impeding future treatment continues to evoke excitement in clinicians and engineers alike. The past five years have yielded impressive advancements in fully absorbable metal stent technology.
large ASD, partial anomalous pulmonary venous return, significant tricuspid regurgitation, carcinoid valvular disease, etc,) 2) Conditions causing pressure overload of the RV. Any cause of pulmonary hypertension. There is normal axis, normal R-wave progression in the precordial leads and no intraventricular conduction abnormalities.
Among these, a fistula between the left anterior descending artery and the pulmonary artery is the rarest variant, comprising about 17% of all coronary artery fistula cases.Case:A 54-year-old male, with a known history of atrial fibrillation and hypertension, presented to our emergency department with non-rotatory dizziness.
Abstract Background The newly introduced nonthermal pulsed field ablation (PFA) is a promising technology to achieve fast pulmonary vein isolation (PVI) with high acute success rates and good safety features. One clinically nonsignificant PV stenosis occurred in the VHPSD group. PFA versus VHPSD for PVI.
Normally, the main pulmonary artery segment will be concave and left atrial appendage region also will be not prominent. So that is why we see straightening of left border, typically heard of in mitral stenosis with left atrial enlargement and mild pulmonary hypertension. Those are not very clear in this picture.
