Subpulmonary membrane: A rare cause of right ventricular outflow tract obstruction.

Subpulmonary membrane is a rare cause of right ventricular outflow tract (RVOT) obstruction, and only a few case reports exist with or without associated ventricular septal defect. We report a series of three cases with subpulmonary membrane causing RVOT obstruction. Two of these have been operated (the first case operated after unsuccessful attempt at balloon dilatation), and the third case is on follow-up at present.

Case series of coronary artery aneurysms after Everolimus eluting stent implantation and comparison with Sirolimus eluting stents.

Background: Coronary artery aneurysms after drug eluting stents are rare. We present a case series of type II coronary aneurysms after implantation of Everolimus eluting stents including patients developing giant aneurysms with a toxic course.

Case Presentation: Over a span of 3.

Unusual Presentation of a Rapidly Progressive Coronary Artery Pseudoaneurysm after Drug Eluting Stent Placement.

Infected coronary artery aneurysm (CAA) is a rare complication of percutaneous coronary intervention (PCI) and is associated with high morbidity and mortality. The management of infected CAA is unclear and is based on the clinical and imaging features. We report an interesting case of a giant infected right CAA secondary to Pseudomonas aeruginosa within four weeks of a drug eluting stent (DES) implantation.

Early hemodynamic performance of the Trifecta™ surgical bioprosthesis aortic valve in Indian patient population: 12 month outcomes of the EVEREST post-market study.

Background: Indian patients undergoing surgical aortic valve replacement (SAVR) differ from western populations with respect to aortic annulus size and valve disease morphology. The purpose of this post-market, non-randomized observational study was to evaluate the early hemodynamic performance of the Trifecta™ bioprosthesis (Abbott, previously St. Jude Medical, Minneapolis, US) in an Indian patient population.

Aortopulmonary Window With Anomalous Coronary Arteries.

Aortopulmonary window associated with anomalous origin of the right coronary artery from the main pulmonary artery is rare. We report a four-month-old male presenting with anomalous origin of both right and left coronary arteries from a single ostium from the anterior sinus of the pulmonary artery along with aortopulmonary window (APW). The patient was managed successfully with a pericardial baffle shunting the coronary ostium to the aorta through the APW.

Reduced left internal mammary artery blood flow on normal sternal retraction.

The left internal mammary artery is the conduit of choice for bypassing the left anterior descending artery. A 72-year-old man underwent off-pump triple-vessel coronary artery bypass. The left internal mammary artery was harvested with brisk blood flow from the distal artery on completion of harvesting, but normal sternal retraction with a Medtronic OctoBase retractor led to cessation of flow.

Ruptured pulmonary artery aneurysm: a surgical emergency.

Idiopathic pulmonary artery aneurysm rupture was diagnosed in a 79-year-old man who presented with a dry cough. He was considered unlikely to tolerate extensive pulmonary artery reconstruction or lung resection; hence, he was salvaged by timely ligation of the distal pulmonary artery at the origin of the aneurysm.

Ruptured hydatid cyst with an unusual presentation.

Ruptured pulmonary hydatid cyst may sometimes cause complications like empyema, bronchopleural fistula, and collapsed lung. These complications may mislead the diagnosis and treatment if prior evidence of cyst has not been documented before rupture. We present a case of a young male who presented with complete collapse of left lung with pyopneumothorax and bronchopleural fistula which was misdiagnosed as pulmonary tuberculosis.

Early anticoagulation after mechanical valve implantation, and related complications.

Background And Aim Of The Study: Anticoagulation is started soon after mechanical valve replacement as the risk of thromboembolic complications is especially high during the first six months after surgery. At present there is no consensus on the optimal protocol to prevent early thrombogenic complications, without increasing the risk of postoperative hemorrhagic events. Herein is presented a comparative analysis of the various anticoagulation protocols utilized at the authors' institution.
