Great artery relationship in DORV
What is the commonest great artery relationship in DORV? Double outlet right ventricle (DORV) is a cyanotic congenital heart disease in which both the aorta and pulmonary artery arises from the right ventricle. There will be an obligatory ventricular septal defect as well for the left ventricular blood to flow out. Commonest great artery relationship in DORV is side by side aorta and pulmonary artery. This pattern is seen in about two thirds of the cases, with aorta to the right of the pulmonary artery. Both semilunar valves will be in the same transverse and coronal planes. Other types of great  artery relationship in DO...

Asymmetric VSD closure device
Complete heart block is an important risk of device closure of perimembranous veentricular septal defect (VSD). This is because of pressure from the device damaging the atrioventricular (AV) conduction system. An asymmetric VSD closure device is found to decrease the chance of complete heart block. Amplatzer asymmetric ventricular septal defect occluder is the one which is used often (AAVSDO) [Pinto RJ et al.

Perventricular closure of ventricular septal defect (VSD)
Perventricular closure of VSD Perventricular closure of VSD is a hybrid procedure. Cardiac surgeon opens the chest and the cardiologist passes a sheath through the right ventricle to achieve a device closure. Heart is exposed through a lower partial sternotomy. The advantage is that cardiopulmonary bypass is not needed. Intra operative trans esophageal echocardiography is used to confirm the size of the defect, its rim from the aortic valve and the function of the aortic valve. The location of the ventricular septal defect is determined intraoperatively by palpating the region over the right ventricle with maximum intensit...

Can a coronary artery fill from the right ventricular injection?
It can occur if the aorta is arising from the right ventricle or when there is a large ventricular septal defect. Another possibility is retrograde filling through the sinusoids in coronary cameral fistula from a coronary artery to the right ventricle. In this case the dye will be seen filling the sinusoids first and then the coronary branches followed by the main coronary artery. Prominent right ventricular sinusoids are seen in pulmonary atresia with intact ventricular septum. (Source: Cardiophile MD)

What is Taussig Bing anomaly?
Taussig Bing anomaly is double outlet right ventricle (DORV) with subpulmonic ventricular septal defect (VSD) and high pulmonary blood flow with pulmonary hypertension. There is a transposition of the aorta to the right ventricle and malposition of the pulmonary artery. It was described by Helen B Taussig and Richard J Bing in 1949. (Source: Cardiophile MD)

If a catheter passes from the right ventricle into the descending aorta, what are the possibilities?
It could be passing through a ventricular septal defect (VSD), patent ductus arteriosus (PDA) or aortopulmonary window (AP window) into the descending aorta. In VSD and AP window, the catheter will form an open loop while in PDA the catheter will form a closed loop (closed loop catheter course in PDA) as it crosses from the pulmonary artery into the descending aorta. Read more on closed loop catheter pattern with illustrative images and video… (Source: Cardiophile MD)

Types of atrial septal defect (ASD)
The types of ASD are: Primum ASD, secundum ASD (also called fossa ovalis type of defect), superior vena caval type of ASD near the orifice of the superior vena cava, inferior vena caval type of ASD near the opening of the inferior vena cava (IVC) without an IVC rim and a coronary sinus type of defect. Primum ASD is associated with cleft anterior mitral leaflet and mitral regurgitation. Superior vena caval defect is associated with partial anomalous pulmonary venous connection. Primum ASD is part of the endocardial cushion defect and atrioventricular septum is absent and the AV valves are at the same level. (Source: Cardiophile MD)

Subacute AnteroSeptal STEMI, With Persistent ST elevation and Upright T-waves
DiscussionWhen there is full thickness infarction, there is epicardial inflammation (post-infarction regional pericarditis), and the myocardium is at risk of "rupture."  The term "rupture" makes it sound like some sort of explosion or massive blowout, but it is usually a small, slow leak that, over time, can cause tamponade and death.  Rupture can be either free wall rupture (causing tamonade) or septal rupture, causing ventricular septal defect with left to right flow and resulting pulmonary edema and shock.  If detected early by ultrasound, the patient can be saved.  Our own Dave Plummer of HCMC repor...

Mechanism of spontaneous closure of ASD
Spontaneous closure of VSD is  a well recognised  phenomenon, than ASD  though both happen in equal frequency.The simple reason being VSD is a noisy disease , ironically the smaller the size of VSD  more noisy it is . Hence  it is rarely  missed  while ASD is largely silent in children. For this reason  it is  possible ASD may be the most common congenital disease . Natural history of ASD(OS) closure ASDs of size 3-4 mm 100 % will close by 3  years Bulk of the ASD < 8  mm close spontaneously by 5 years. ASD> 10mm is unlikely to close Factors that determine spontaneous closure Apart from size and locatio...

Fallot’s tetralogy Correct answer: 4) Fallot’s tetralogy Bisferiens pulse (pulsus bisferiens) has two systolic peaks and is seen in both free (severe) aortic regurgitation and a combination of aortic regurgitation and stenosis, especially when the regurgitation is dominant. In severe aortic stenosis, the pulse is low volume and slow peaking – pulsus parvus et tardus. In hypertrophic obstructive cardiomyopathy (HOCM), soo...

Sealant Inspired By Beach Worm Could Become Surgical Superglue
Remember that wacky glue commercial from the 1980s? "Krazy Glue, you crazy rat," the narrator says. "Strong enough to hold this man suspended in mid-air." He promises the stuff can bond almost anything: a plastic knob, a plastic plug, a rubber boot, a door knob, and even a flashlight case.Heck, a version of the everlasting adhesive is even approved by the Food and Drug Administration to seal skin wounds.But superglue can't fix a broken heart — or even a torn artery. Yet.Now a team of doctors and engineers at Brigham and Women's Hospital in Boston are getting close to changing that. Their unlikely inspiration is a 3-inch ...
