A 64-year-old female had symptomatic severe aortic insufficiency and was taken up for aortic valve replacement. The patient was found to have a quadricuspid aortic valve and abnormally located early bifurcated left coronary ostium which were very near to the commissures. There is a risk of damaging the coronary ostia while excising the valve or the prosthetic valve can obstruct the abnormally located ostia. Intraoperative transesophageal echocardiography can help in making an accurate intraoperative diagnosis and deciding aortotomy incision and valve excision. This patient underwent successful aortic valve replacement taking great care to save the abnormally located left coronary ostium.

| Introduction|| |
A quadricuspid aortic valve is a rare congenital anomaly which can lead to aortic insufficiency or aortic stenosis. If the patient needs aortic valve replacement, the rare association with the abnormal location of coronary ostia should be kept in mind to avoid prosthetic valve induced obstruction of coronary ostia.
| Case Report|| |
A 64-year-old female who had breathlessness and palpitations of progressing severity for about 5 years was diagnosed with symptomatic severe aortic regurgitation on transthoracic echocardiography which showed thickened tricuspid aortic valve with a 7 mm vena contracta of a central jet. She was found to have a degenerative aortic valve and was referred for aortic valve replacement. Intraoperative transesophageal echocardiography (TEE) surprisingly showed a quadricuspid aortic valve [Figure 1] with malcoapting leaflets and a central regurgitant jet. This was confirmed intraoperatively when a thickened degenerative quadricuspid aortic valve was found with four equal sized cusps [Figure 2]. There were also two left coronary ostia due to the early bifurcation of the left coronary artery, and both the left coronary ostia were located very close to the commissures [Figure 3]. The aortic valve was excised and successfully replaced with aortic bioprosthesis (EPIC St. Jude Minn., USA) taking great care to save the abnormally located coronary ostia. The patient recovered well in the postoperative period without any complications.

| Discussion|| |
Quadricuspid aortic valve is a rare congenital anomaly with the first case report published in 1862 by Balington and more than 200 cases have been reported till date. The prevalence of quadricuspid aortic valve according to historical autopsy reports is around 0.008% in a report by Simonds. Quadricuspid aortic valves are mostly discovered incidentally during echocardiography, autopsy or during surgery but an accurate preoperative diagnosis is important because though a quadricuspid aortic valve occurs as an isolated anomaly, but various associated anomalies have been seen including atrial septal defect, pulmonary stenosis, ventricular septal defect, hypertrophic obstructive cardiomyopathy  and aortic aneurysm. One of such anomalies associated with a quadricuspid aortic valve is an abnormally located coronary ostia  and there is a case report of obstruction of low-lying coronary ostia by the prosthetic aortic valve. Surgeons should, therefore, be careful while implanting the aortic prosthetic valve in such a condition. TEE can be of great help in making an accurate intraoperative diagnosis, deciding aortotomy incision and for valve excision. Hurwitz and Roberts  have classified quadricuspid aortic valves into seven types out of which Type A and B are the most common. Our patient had Type A quadricuspid valve according to this classification.
Type A: Four equal cusps
Type B: Three equal cusps and one smaller cusp
Type C: Two equal larger cusps and two equal smaller cusps
Type D: One large, two intermediate and one smaller cusp
Type E: Three equal cusps and one larger cusp
Type F: Two equal larger cusps and two inequal smaller cusps
Type G: Four inequal cusps.
In a review article by Yamagishi et al., 192 cases were reviewed till December 2004 and mean age of patients was found to be 51 years with a female preponderance. About 60% of patients had aortic regurgitation at the time of presentation while aortic stenosis was seen in 8% of patients and 7% of patients had a normal functioning valve.
| Conclusion|| |
A quadricuspid aortic valve is a rare congenital anomaly which can lead to aortic valve problems. If the patient needs aortic valve replacement, abnormal location of coronary ostia should be kept in mind. In this patient, there there were two left coronary ostia and they were close to the commissures. Surgery with successful with implantation of a aortic bioprosthesis, with no damage to the coronary ostia.
